ASSESSMENT AND DIAGNOSIS OF ATHLETIC INJURIES DEVELOP SKILLS TO ASSESS
AND DIAGNOSE VARIOUS SPORTS-RELATED INJURIES
1. Question: In a basketball player presenting with knee pain, the athlete reports that the pain started
gradually and worsened over several weeks. The pain is localized to the front of the knee and becomes more
intense when jumping or running. The player denies any sudden traumatic event that caused the pain. On
examination, there is tenderness at the inferior pole of the patella. Based on this information, what is the
most likely diagnosis according to the presentation described?
Solution: The presenting symptoms of gradual onset knee pain exacerbated by activities such as jumping
or running, without a history of acute trauma, are indicative of an overuse injury rather than an acute injury.
The tenderness at the inferior pole of the patella is a classic sign of patellar tendinopathy, commonly known
as jumper’s knee.
Thus, based on the presentation described, the most likely diagnosis is patellar tendinopathy or jumper’s
knee, an overuse injury often seen in athletes engaging in jumping sports like basketball.
Numerical Answer: Patellar tendinopathy
2. Question: A soccer player sustains an injury during a match where she feels a sharp pain in her
knee. The team physician suspects a possible ACL tear and decides to conduct an MRI scan to confirm the
diagnosis. The MRI report reveals a Grade 2 ACL tear. According to the classification system for ACL
tears, what percentage of fibers is disrupted in a Grade 2 tear?
Solution: - Grade 2 ACL tear involves a significant but incomplete tear of the ligament, where approx-
imately 50-90- To find the percentage of ligament fibers disrupted in a Grade 2 tear, we can calculate the
average of the range provided: (50 + 90) / 2 = 70- Therefore, in a Grade 2 ACL tear, approximately 70
3. Question: During a sports event, a soccer player collides with an opponent and experiences pain
and tenderness over the lateral aspect of their ankle. The player has difficulty weight-bearing and walking
without support. Upon examination, the player has localized swelling and ecchymosis over the lateral
malleolus. What is the most common injury that fits this presentation, and what percentage of lateral ankle
sprains is this injury responsible for in athletes?
Solution: The most common injury that fits this presentation is a lateral ankle sprain, specifically involv-
ing the anterior talofibular ligament (ATFL). The ATFL is responsible for approximately 70-85Therefore,
the correct numerical answer is: 70-85
4. Question: A basketball player presents with a knee injury after landing awkwardly during a game.
Upon assessment, it is noted that there is tenderness and swelling around the joint. The player reports
hearing a "pop" at the time of injury. Based on the mechanism of injury and clinical presentation, what is
the most likely diagnosis score on the Ottawa Knee Rule assessment (range: 0-10)?
Solution: The Ottawa Knee Rule is a clinical decision rule used to help determine the need for X-rays
in patients presenting with acute knee injuries. It assigns points based on specific criteria related to the
mechanism of injury and clinical findings.
For this scenario described in the question: - Tenderness at the head of the fibula: 1 point - Isolated
patellar tenderness: 1 point - Unable to flex knee to 90 degrees: 1 point - Inability to bear weight both
immediately and in the emergency department for four steps: 1 point - Age 55 years old or older: 1 point
Given the information provided (tenderness, swelling, "pop" sound), we can likely assign a point for
tenderness at the head of the fibula and a point for isolated patellar tenderness, resulting in a total of 2
points. The inability to bear weight and age criteria are not mentioned in the scenario.
Therefore, the most likely Ottawa Knee Rule assessment score for this injury based on the given infor-
mation is 2 points.
5. Question: A basketball player presents with pain in the anterior knee that worsens with running,
jumping, and cutting movements. Upon assessment, the athletic trainer notes tenderness at the inferior
pole of the patella, along with pain during resisted knee extension. The player reports that the pain started
gradually and has been persistent for the past 6 weeks. Based on these findings, what is the most likely
diagnosis?
Solution: The description provided aligns with the signs and symptoms of patellar tendinopathy, com-
monly known as jumper’s knee. This condition is characterized by pain and tenderness at the inferior pole
of the patella, especially with activities that involve repetitive jumping, running, or cutting movements. The
gradual onset and persistence of symptoms over 6 weeks further support this diagnosis.
Numerical Answer: Patellar tendinopathy
6. Question: In the assessment of a concussion in an athletic injury, how many key symptoms must be
present to diagnose a concussion according to the Sport Concussion Assessment Tool (SCAT-5)?
Solution: According to the Sport Concussion Assessment Tool (SCAT-5), the diagnosis of a concussion
is based on the presence of at least 1 of 22 key symptoms. So, the numerical answer is 1 symptom.
7. Question: During a concussion assessment, which numerical value on the Glasgow Coma Scale
would indicate a severe brain injury?
Solution: The Glasgow Coma Scale (GCS) is used to assess the level of consciousness in a patient with
an acute brain injury, such as a concussion. The scale ranges from 3 to 15, with lower scores indicating
more severe brain injury. A GCS score of 8 or below is considered indicative of a severe brain injury. This
level of severity requires immediate medical attention and intervention.
8. Question: During a standardized sideline assessment for a suspected concussion in an athlete, how
many total questions are typically included in the Standardized Assessment of Concussion (SAC) test?
Solution: The Standardized Assessment of Concussion (SAC) test includes the following components:
orientation questions (5 questions), immediate memory (5 words to remember), concentration (serial sub-
traction tasks), and delayed recall (recalling the 5 words mentioned earlier). Therefore, the total number of
questions in the SAC test is 5 (orientation) + 5 (immediate memory) + 3 (concentration tasks) = 13 questions.
Answer: 13
9. Question: In a patient with a suspected ACL injury, an MRI scan reveals a tear of 1.5 cm in length. If
the total length of the ACL is considered to be 3.5 cm, what percentage of the ACL is affected by the tear?
Solution: To calculate the percentage of the ACL affected by the tear, we will use the formula: Percent-
age affected = (Length of tear / Total length of ACL) * 100
Given: Length of tear = 1.5 cm Total length of ACL = 3.5 cm
Substitute the given values into the formula: Percentage affected = (1.5 cm / 3.5 cm) * 100 Percentage
affected = (0.4286) * 100 Percentage affected 42.86
Therefore, the tear affects approximately 42.86
10. Question: A soccer player presents with pain in their knee after a match. Upon assessment, you
notice swelling, tenderness, and a history of gradual onset of pain over the past 4 weeks. Based on the
presentation, is this sports injury most likely acute or chronic?
Solution: - Acute injuries are typically sudden onset injuries due to an immediate trauma to the body.
Chronic injuries, on the other hand, develop over time due to repetitive stress or overuse.
- In this case, the soccer player’s history of gradual onset of pain over 4 weeks indicates a chronic injury.
Therefore, the sports injury in this scenario is most likely chronic.
11. Question:
During an assessment of an athlete’s ankle injury, the sports medicine professional conducts a Thompson
test to evaluate the integrity of the Achilles tendon. If the athlete’s ankle plantarflexes by 0 degrees compared
to the unaffected side during the test, what percentage of probability does this indicate of a complete Achilles
tendon rupture?
Solution:
A Thompson test is used to assess the integrity of the Achilles tendon, specifically to check for a com-
plete rupture. In a positive Thompson test (0 degrees of ankle plantarflexion), where there is no movement of
the foot in response to calf squeezing, it indicates a high probability of a complete Achilles tendon rupture.
Research indicates that a positive Thompson test has a high sensitivity and specificity for a complete
Achilles tendon rupture, with a likelihood ratio of around 30. This means that a positive test significantly
increases the probability of a complete tear.
Therefore, if the athlete’s ankle plantarflexes by 0 degrees during the Thompson test, it indicates almost
a 100
12. Question: A soccer player presents with pain in their knee that started gradually after increasing
their training intensity over the past few weeks. Upon assessment, the player reports tenderness along the
patellar tendon insertion and pain with running and jumping. Based on the presentation and assessment
findings, what type of sports injury is most likely occurring: acute or chronic? Provide your answer as a
numerical value: 1. Acute 2. Chronic
Solution: Chronic sports injuries develop over time due to repetitive overuse or stress on the body. The
gradual onset of pain after increasing training intensity and tenderness at the patellar tendon insertion point
in this scenario suggest a chronic injury related to overuse. Therefore, the most likely type of sports injury
occurring in this case is: 2. Chronic
13. Question: A basketball player presents with ankle pain after landing awkwardly during a game. The
pain developed suddenly and is localized to the lateral aspect of the ankle. The player reports a popping
sound at the time of injury. Based on this description, on a scale of 1 to 10, how likely is this injury to be
acute rather than chronic?
Solution: In this scenario, an acute injury is more probable due to the sudden onset of pain, localized
pain on the lateral aspect of the ankle (typical for an ankle sprain), and the player reporting a popping sound
which is often associated with ligamentous injury during an acute trauma. Acute injuries typically present
with immediate pain, swelling, and instability. Chronic injuries, on the other hand, develop over time due to
repetitive stress or overuse.
On a scale of 1 to 10, with 1 being very unlikely and 10 being highly likely, the likelihood of this injury
being acute rather than chronic would be around 9.
14. Question: A basketball player presents with symptoms of shoulder pain and limited range of motion.
During assessment, you perform the O’Brien’s Test for labral tears. If the player experiences pain at 90
degrees of shoulder flexion and internal rotation but no pain at 30 degrees of shoulder flexion and internal
rotation, what is the likelihood ratio for a labral tear based on this test result?
Solution: The likelihood ratio for a labral tear can be calculated using the following formula:
Likelihood Ratio =Sensitivity
1−Specificity
First, let’s determine the sensitivity and specificity of the O’Brien’s Test. Sensitivity is the ability of a test to
correctly identify those with the condition, and specificity is the ability of the test to correctly identify those
without the condition.
For the O’Brien’s Test: - Sensitivity: 95- Specificity: 80
Now we can plug in these values into the formula:
Likelihood Ratio =0.95
1−0.80 =0.95
0.20 = 4.75
Therefore, the likelihood ratio for a labral tear based on the O’Brien’s Test result in this case is 4.75.
15. Question: A basketball player presents with pain in the front of their knee and reports that the
symptoms started gradually after increasing their training intensity. On physical examination, they exhibit
tenderness over the inferior pole of the patella and pain with resisted knee extension. What is the most likely
diagnosis for this athlete?
Solution: The symptoms described are characteristic of patellar tendonitis, which is an overuse injury
commonly seen in athletes engaging in sports with repetitive jumping and running. The gradual onset
of symptoms, tenderness over the inferior pole of the patella, and pain with resisted knee extension are
all indicative of patellar tendonitis. To manage this condition, it is important to address the contributing
factors such as overtraining, poor biomechanics, or muscle imbalances through rest, activity modification,
stretching, strengthening exercises, and possibly physical therapy.
The numerical answer: Patellar tendonitis
16. Question: In the assessment of concussions in sports, what is the typical range of scores on the Sport
Concussion Assessment Tool (SCAT) that may indicate a potential concussion?
Solution: The Sport Concussion Assessment Tool (SCAT) is a standardized tool used to assess athletes
for concussions. One component of the SCAT is the Standardized Assessment of Concussion (SAC) portion,
where athletes are evaluated based on their cognitive function through a series of tasks. A typical range of
scores on the SAC portion of the SCAT that may indicate a potential concussion is between 25 to 30 points.
Scores lower than 25 are often considered indicative of a concussion, although it’s essential to evaluate other
factors in conjunction with the SAC score for an accurate diagnosis.
17. Question: In assessing a football player with a suspected grade 2 hamstring strain, how many weeks
of recovery time would typically be recommended?
Solution: A grade 2 hamstring strain involves a significant tear within the muscle resulting in moderate to
severe pain and loss of function. The typical recovery time for a grade 2 hamstring strain in a football player
ranges from 4 to 8 weeks, depending on the extent of the injury and individual healing factors. Therefore,
the recommended recovery time for a grade 2 hamstring strain is approximately 6 weeks.
Answer: 6 weeks
18. Question: An athlete presents with a suspected ankle sprain after a basketball game. A radiograph
of the ankle reveals a lateral malleolus avulsion fracture measuring 5mm in displacement. According to the
Ottawa ankle rules, what is the maximum acceptable displacement for a lateral malleolus avulsion fracture
without requiring further imaging like a CT scan?
Solution: According to the Ottawa ankle rules, for avulsion fractures of the lateral malleolus on ankle
radiographs, the maximum acceptable displacement allowed without needing further imaging is 2mm. In
this case, the 5mm displacement exceeds the threshold, indicating the need for further imaging like a CT
scan.
19. Question: A basketball player experiences an injury to his ankle during a game. The player reports
that the pain started gradually over the past few weeks and has been persistent during games. Based on this
history, is the ankle injury more likely to be considered acute or chronic? Provide your answer in weeks.
Solution: Chronic injuries typically develop over a longer period, often weeks to months, and are char-
acterized by persistent or recurring pain or discomfort. In contrast, acute injuries occur suddenly and are
usually associated with a specific incident.
In this scenario, since the basketball player reports that the pain started gradually over the past few
weeks and has been persistent during games, the ankle injury is more likely to be considered chronic. The
injury has been ongoing for multiple weeks, indicating a longer development time associated with chronic
injuries. Therefore, the ankle injury is chronic and has been persisting for several weeks.
20. Question: A basketball player presents with sharp pain on the lateral aspect of their ankle following
a recent game. Upon assessment, you suspect either a lateral ankle sprain or a peroneal tendon injury. To
differentiate between the two, you perform the anterior drawer test and note that the talar tilt angle is 10
degrees. What is the most likely injury based on this information?
Solution: The anterior drawer test is used to assess the integrity of the anterior talofibular ligament
(ATFL) in cases of an ankle sprain. If the test is positive (indicating excessive anterior translation of the
talus on the tibia), it is suggestive of a ligamentous injury, such as a lateral ankle sprain. On the other
hand, the talar tilt test is used to assess instability related to the calcaneofibular ligament and the anterior
talofibular ligament. Typically, a talar tilt angle greater than 10 degrees is considered indicative of lateral
ankle instability, often seen in cases of lateral ankle sprains.
Therefore, based on the information provided and the talar tilt angle of 10 degrees, the most likely injury
is a lateral ankle sprain.
21. Question: A soccer player presents with sharp pain in the knee, especially when cutting and pivot-
ing. During the physical exam, the athletic trainer notes tenderness on the medial joint line and a positive
McMurray test. What is the most likely differential diagnosis in this case?
Solution: The symptoms described - sharp pain on the medial joint line, exacerbated with cutting and
a positive McMurray test - are indicative of a meniscal injury. Meniscal tears are common in sports that
involve cutting and pivoting movements like soccer. Therefore, the most likely differential diagnosis in this
case is a meniscal injury.
22. Question: What is the most common grade of ankle sprain in athletes based on lateral ligament
injuries assessment?
Solution: Grade 2 ankle sprain is the most common grade among athletes when assessing lateral liga-
ment injuries. This grade is characterized by partial tearing of the ligament, leading to moderate swelling,
bruising, and instability of the joint. Grade 2 ankle sprains usually require a longer recovery time compared
to Grade 1 sprains but have a better prognosis compared to Grade 3 sprains where the ligament is completely
torn.
23. Question: A basketball player presents with acute pain in the ankle after landing awkwardly from
a jump. On examination, there is tenderness and swelling around the lateral malleolus. The player has
difficulty bearing weight on the affected side. What is the most likely injury based on this presentation?
Solution: The presentation described is consistent with a lateral ankle sprain, which is a common sports-
related injury. The tenderness and swelling around the lateral malleolus, along with difficulty bearing
weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized
under the SCAT5 (Sport Concussion Assessment Tool 5) should be present at minimum to indicate a likely
concussion?
Solution: The SCAT5 consists of 22 symptoms, and according to the SCAT5 guidelines, if an athlete
presents with at least one of the 10 signs of this tool and at least one of the 22 symptoms, it may indicate a
likely concussion. Therefore, a minimum of two symptoms should be present to suggest a likely concussion.
25. Question: During a knee assessment, a sports medicine physician performs the anterior drawer test
to assess for anterior cruciate ligament (ACL) injury. The displacement of the tibia in millimeters from its
starting position to its furthest point is measured. If the physician notes a displacement of 8mm during the
anterior drawer test, how would you interpret this finding?
Solution: The anterior drawer test assesses the integrity of the ACL. A displacement of more than 6mm
in the anterior drawer test is indicative of a positive test for an ACL injury. In this case, with a displacement
of 8mm during the test, it suggests a positive finding for an ACL injury, indicating possible ligamentous
laxity and instability in the knee joint. Further imaging studies, such as MRI, might be warranted for a more
detailed evaluation and confirmation of the ACL injury.
5. Question: A basketball player presents with pain in the anterior knee that worsens with running,
jumping, and cutting movements. Upon assessment, the athletic trainer notes tenderness at the inferior
pole of the patella, along with pain during resisted knee extension. The player reports that the pain started
gradually and has been persistent for the past 6 weeks. Based on these findings, what is the most likely
diagnosis?
Solution: The description provided aligns with the signs and symptoms of patellar tendinopathy, com-
monly known as jumper’s knee. This condition is characterized by pain and tenderness at the inferior pole
of the patella, especially with activities that involve repetitive jumping, running, or cutting movements. The
gradual onset and persistence of symptoms over 6 weeks further support this diagnosis.
Numerical Answer: Patellar tendinopathy
6. Question: In the assessment of a concussion in an athletic injury, how many key symptoms must be
present to diagnose a concussion according to the Sport Concussion Assessment Tool (SCAT-5)?
Solution: According to the Sport Concussion Assessment Tool (SCAT-5), the diagnosis of a concussion
is based on the presence of at least 1 of 22 key symptoms. So, the numerical answer is 1 symptom.
7. Question: During a concussion assessment, which numerical value on the Glasgow Coma Scale
would indicate a severe brain injury?
Solution: The Glasgow Coma Scale (GCS) is used to assess the level of consciousness in a patient with
an acute brain injury, such as a concussion. The scale ranges from 3 to 15, with lower scores indicating
more severe brain injury. A GCS score of 8 or below is considered indicative of a severe brain injury. This
level of severity requires immediate medical attention and intervention.
8. Question: During a standardized sideline assessment for a suspected concussion in an athlete, how
many total questions are typically included in the Standardized Assessment of Concussion (SAC) test?
Solution: The Standardized Assessment of Concussion (SAC) test includes the following components:
orientation questions (5 questions), immediate memory (5 words to remember), concentration (serial sub-
traction tasks), and delayed recall (recalling the 5 words mentioned earlier). Therefore, the total number of
questions in the SAC test is 5 (orientation) + 5 (immediate memory) + 3 (concentration tasks) = 13 questions.
Answer: 13
9. Question: In a patient with a suspected ACL injury, an MRI scan reveals a tear of 1.5 cm in length. If
the total length of the ACL is considered to be 3.5 cm, what percentage of the ACL is affected by the tear?
Solution: To calculate the percentage of the ACL affected by the tear, we will use the formula: Percent-
age affected = (Length of tear / Total length of ACL) * 100
Given: Length of tear = 1.5 cm Total length of ACL = 3.5 cm
Substitute the given values into the formula: Percentage affected = (1.5 cm / 3.5 cm) * 100 Percentage
affected = (0.4286) * 100 Percentage affected 42.86
Therefore, the tear affects approximately 42.86
10. Question: A soccer player presents with pain in their knee after a match. Upon assessment, you
notice swelling, tenderness, and a history of gradual onset of pain over the past 4 weeks. Based on the
presentation, is this sports injury most likely acute or chronic?
Solution: - Acute injuries are typically sudden onset injuries due to an immediate trauma to the body.
Chronic injuries, on the other hand, develop over time due to repetitive stress or overuse.
- In this case, the soccer player’s history of gradual onset of pain over 4 weeks indicates a chronic injury.
Therefore, the sports injury in this scenario is most likely chronic.

a 100
12. Question: A soccer player presents with pain in their knee that started gradually after increasing
their training intensity over the past few weeks. Upon assessment, the player reports tenderness along the
patellar tendon insertion and pain with running and jumping. Based on the presentation and assessment
findings, what type of sports injury is most likely occurring: acute or chronic? Provide your answer as a
numerical value: 1. Acute 2. Chronic
Solution: Chronic sports injuries develop over time due to repetitive overuse or stress on the body. The
gradual onset of pain after increasing training intensity and tenderness at the patellar tendon insertion point
in this scenario suggest a chronic injury related to overuse. Therefore, the most likely type of sports injury
occurring in this case is: 2. Chronic
13. Question: A basketball player presents with ankle pain after landing awkwardly during a game. The
pain developed suddenly and is localized to the lateral aspect of the ankle. The player reports a popping
sound at the time of injury. Based on this description, on a scale of 1 to 10, how likely is this injury to be
acute rather than chronic?
Solution: In this scenario, an acute injury is more probable due to the sudden onset of pain, localized
pain on the lateral aspect of the ankle (typical for an ankle sprain), and the player reporting a popping sound
which is often associated with ligamentous injury during an acute trauma. Acute injuries typically present
with immediate pain, swelling, and instability. Chronic injuries, on the other hand, develop over time due to
repetitive stress or overuse.
On a scale of 1 to 10, with 1 being very unlikely and 10 being highly likely, the likelihood of this injury
being acute rather than chronic would be around 9.

degrees of shoulder flexion and internal rotation but no pain at 30 degrees of shoulder flexion and internal
rotation, what is the likelihood ratio for a labral tear based on this test result?
Solution: The likelihood ratio for a labral tear can be calculated using the following formula:
Likelihood Ratio =Sensitivity
1−Specificity
First, let’s determine the sensitivity and specificity of the O’Brien’s Test. Sensitivity is the ability of a test to
correctly identify those with the condition, and specificity is the ability of the test to correctly identify those

Now we can plug in these values into the formula:
Likelihood Ratio =0.95
1−0.80 =0.95
0.20 = 4.75
Therefore, the likelihood ratio for a labral tear based on the O’Brien’s Test result in this case is 4.75.
15. Question: A basketball player presents with pain in the front of their knee and reports that the
symptoms started gradually after increasing their training intensity. On physical examination, they exhibit
tenderness over the inferior pole of the patella and pain with resisted knee extension. What is the most likely
diagnosis for this athlete?
Solution: The symptoms described are characteristic of patellar tendonitis, which is an overuse injury
commonly seen in athletes engaging in sports with repetitive jumping and running. The gradual onset
of symptoms, tenderness over the inferior pole of the patella, and pain with resisted knee extension are
all indicative of patellar tendonitis. To manage this condition, it is important to address the contributing

talofibular ligament. Typically, a talar tilt angle greater than 10 degrees is considered indicative of lateral
ankle instability, often seen in cases of lateral ankle sprains.
Therefore, based on the information provided and the talar tilt angle of 10 degrees, the most likely injury
is a lateral ankle sprain.
21. Question: A soccer player presents with sharp pain in the knee, especially when cutting and pivot-
ing. During the physical exam, the athletic trainer notes tenderness on the medial joint line and a positive
McMurray test. What is the most likely differential diagnosis in this case?
Solution: The symptoms described - sharp pain on the medial joint line, exacerbated with cutting and

involve cutting and pivoting movements like soccer. Therefore, the most likely differential diagnosis in this
case is a meniscal injury.
22. Question: What is the most common grade of ankle sprain in athletes based on lateral ligament
injuries assessment?
Solution: Grade 2 ankle sprain is the most common grade among athletes when assessing lateral liga-
ment injuries. This grade is characterized by partial tearing of the ligament, leading to moderate swelling,
bruising, and instability of the joint. Grade 2 ankle sprains usually require a longer recovery time compared
to Grade 1 sprains but have a better prognosis compared to Grade 3 sprains where the ligament is completely
torn.
23. Question: A basketball player presents with acute pain in the ankle after landing awkwardly from
a jump. On examination, there is tenderness and swelling around the lateral malleolus. The player has
difficulty bearing weight on the affected side. What is the most likely injury based on this presentation?
Solution: The presentation described is consistent with a lateral ankle sprain, which is a common sports-
related injury. The tenderness and swelling around the lateral malleolus, along with difficulty bearing
weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized
under the SCAT5 (Sport Concussion Assessment Tool 5) should be present at minimum to indicate a likely
concussion?
Solution: The SCAT5 consists of 22 symptoms, and according to the SCAT5 guidelines, if an athlete
presents with at least one of the 10 signs of this tool and at least one of the 22 symptoms, it may indicate a
likely concussion. Therefore, a minimum of two symptoms should be present to suggest a likely concussion.
25. Question: During a knee assessment, a sports medicine physician performs the anterior drawer test
to assess for anterior cruciate ligament (ACL) injury. The displacement of the tibia in millimeters from its
starting position to its furthest point is measured. If the physician notes a displacement of 8mm during the
anterior drawer test, how would you interpret this finding?
Solution: The anterior drawer test assesses the integrity of the ACL. A displacement of more than 6mm
in the anterior drawer test is indicative of a positive test for an ACL injury. In this case, with a displacement
of 8mm during the test, it suggests a positive finding for an ACL injury, indicating possible ligamentous
laxity and instability in the knee joint. Further imaging studies, such as MRI, might be warranted for a more
detailed evaluation and confirmation of the ACL injury.
5. Question: A basketball player presents with pain in the anterior knee that worsens with running,
jumping, and cutting movements. Upon assessment, the athletic trainer notes tenderness at the inferior
pole of the patella, along with pain during resisted knee extension. The player reports that the pain started
gradually and has been persistent for the past 6 weeks. Based on these findings, what is the most likely
diagnosis?
Solution: The description provided aligns with the signs and symptoms of patellar tendinopathy, com-
monly known as jumper’s knee. This condition is characterized by pain and tenderness at the inferior pole
of the patella, especially with activities that involve repetitive jumping, running, or cutting movements. The
gradual onset and persistence of symptoms over 6 weeks further support this diagnosis.
Numerical Answer: Patellar tendinopathy
6. Question: In the assessment of a concussion in an athletic injury, how many key symptoms must be
present to diagnose a concussion according to the Sport Concussion Assessment Tool (SCAT-5)?
Solution: According to the Sport Concussion Assessment Tool (SCAT-5), the diagnosis of a concussion
is based on the presence of at least 1 of 22 key symptoms. So, the numerical answer is 1 symptom.
7. Question: During a concussion assessment, which numerical value on the Glasgow Coma Scale
would indicate a severe brain injury?
Solution: The Glasgow Coma Scale (GCS) is used to assess the level of consciousness in a patient with
an acute brain injury, such as a concussion. The scale ranges from 3 to 15, with lower scores indicating
more severe brain injury. A GCS score of 8 or below is considered indicative of a severe brain injury. This
level of severity requires immediate medical attention and intervention.
8. Question: During a standardized sideline assessment for a suspected concussion in an athlete, how
many total questions are typically included in the Standardized Assessment of Concussion (SAC) test?
Solution: The Standardized Assessment of Concussion (SAC) test includes the following components:
orientation questions (5 questions), immediate memory (5 words to remember), concentration (serial sub-
traction tasks), and delayed recall (recalling the 5 words mentioned earlier). Therefore, the total number of
questions in the SAC test is 5 (orientation) + 5 (immediate memory) + 3 (concentration tasks) = 13 questions.
Answer: 13
9. Question: In a patient with a suspected ACL injury, an MRI scan reveals a tear of 1.5 cm in length. If
the total length of the ACL is considered to be 3.5 cm, what percentage of the ACL is affected by the tear?
Solution: To calculate the percentage of the ACL affected by the tear, we will use the formula: Percent-
age affected = (Length of tear / Total length of ACL) * 100
Given: Length of tear = 1.5 cm Total length of ACL = 3.5 cm
Substitute the given values into the formula: Percentage affected = (1.5 cm / 3.5 cm) * 100 Percentage
affected = (0.4286) * 100 Percentage affected 42.86
Therefore, the tear affects approximately 42.86
10. Question: A soccer player presents with pain in their knee after a match. Upon assessment, you
notice swelling, tenderness, and a history of gradual onset of pain over the past 4 weeks. Based on the
presentation, is this sports injury most likely acute or chronic?
Solution: - Acute injuries are typically sudden onset injuries due to an immediate trauma to the body.
Chronic injuries, on the other hand, develop over time due to repetitive stress or overuse.
- In this case, the soccer player’s history of gradual onset of pain over 4 weeks indicates a chronic injury.
Therefore, the sports injury in this scenario is most likely chronic.
11. Question:
During an assessment of an athlete’s ankle injury, the sports medicine professional conducts a Thompson
test to evaluate the integrity of the Achilles tendon. If the athlete’s ankle plantarflexes by 0 degrees compared
to the unaffected side during the test, what percentage of probability does this indicate of a complete Achilles
tendon rupture?
Solution:
A Thompson test is used to assess the integrity of the Achilles tendon, specifically to check for a com-
plete rupture. In a positive Thompson test (0 degrees of ankle plantarflexion), where there is no movement of
the foot in response to calf squeezing, it indicates a high probability of a complete Achilles tendon rupture.
Research indicates that a positive Thompson test has a high sensitivity and specificity for a complete
Achilles tendon rupture, with a likelihood ratio of around 30. This means that a positive test significantly
increases the probability of a complete tear.
Therefore, if the athlete’s ankle plantarflexes by 0 degrees during the Thompson test, it indicates almost
a 100
12. Question: A soccer player presents with pain in their knee that started gradually after increasing
their training intensity over the past few weeks. Upon assessment, the player reports tenderness along the
patellar tendon insertion and pain with running and jumping. Based on the presentation and assessment
findings, what type of sports injury is most likely occurring: acute or chronic? Provide your answer as a
numerical value: 1. Acute 2. Chronic
Solution: Chronic sports injuries develop over time due to repetitive overuse or stress on the body. The
gradual onset of pain after increasing training intensity and tenderness at the patellar tendon insertion point
in this scenario suggest a chronic injury related to overuse. Therefore, the most likely type of sports injury
occurring in this case is: 2. Chronic
13. Question: A basketball player presents with ankle pain after landing awkwardly during a game. The
pain developed suddenly and is localized to the lateral aspect of the ankle. The player reports a popping
sound at the time of injury. Based on this description, on a scale of 1 to 10, how likely is this injury to be
acute rather than chronic?
Solution: In this scenario, an acute injury is more probable due to the sudden onset of pain, localized
pain on the lateral aspect of the ankle (typical for an ankle sprain), and the player reporting a popping sound
which is often associated with ligamentous injury during an acute trauma. Acute injuries typically present
with immediate pain, swelling, and instability. Chronic injuries, on the other hand, develop over time due to
repetitive stress or overuse.
On a scale of 1 to 10, with 1 being very unlikely and 10 being highly likely, the likelihood of this injury
being acute rather than chronic would be around 9.
14. Question: A basketball player presents with symptoms of shoulder pain and limited range of motion.
During assessment, you perform the O’Brien’s Test for labral tears. If the player experiences pain at 90
degrees of shoulder flexion and internal rotation but no pain at 30 degrees of shoulder flexion and internal
rotation, what is the likelihood ratio for a labral tear based on this test result?
Solution: The likelihood ratio for a labral tear can be calculated using the following formula:
Likelihood Ratio =Sensitivity
1−Specificity
First, let’s determine the sensitivity and specificity of the O’Brien’s Test. Sensitivity is the ability of a test to
correctly identify those with the condition, and specificity is the ability of the test to correctly identify those
without the condition.
For the O’Brien’s Test: - Sensitivity: 95- Specificity: 80
Now we can plug in these values into the formula:
Likelihood Ratio =0.95
1−0.80 =0.95
0.20 = 4.75
Therefore, the likelihood ratio for a labral tear based on the O’Brien’s Test result in this case is 4.75.
15. Question: A basketball player presents with pain in the front of their knee and reports that the
symptoms started gradually after increasing their training intensity. On physical examination, they exhibit
tenderness over the inferior pole of the patella and pain with resisted knee extension. What is the most likely
diagnosis for this athlete?
Solution: The symptoms described are characteristic of patellar tendonitis, which is an overuse injury
commonly seen in athletes engaging in sports with repetitive jumping and running. The gradual onset
of symptoms, tenderness over the inferior pole of the patella, and pain with resisted knee extension are
all indicative of patellar tendonitis. To manage this condition, it is important to address the contributing
factors such as overtraining, poor biomechanics, or muscle imbalances through rest, activity modification,
stretching, strengthening exercises, and possibly physical therapy.
The numerical answer: Patellar tendonitis
16. Question: In the assessment of concussions in sports, what is the typical range of scores on the Sport
Concussion Assessment Tool (SCAT) that may indicate a potential concussion?
Solution: The Sport Concussion Assessment Tool (SCAT) is a standardized tool used to assess athletes
for concussions. One component of the SCAT is the Standardized Assessment of Concussion (SAC) portion,
where athletes are evaluated based on their cognitive function through a series of tasks. A typical range of
scores on the SAC portion of the SCAT that may indicate a potential concussion is between 25 to 30 points.
Scores lower than 25 are often considered indicative of a concussion, although it’s essential to evaluate other
factors in conjunction with the SAC score for an accurate diagnosis.
17. Question: In assessing a football player with a suspected grade 2 hamstring strain, how many weeks
of recovery time would typically be recommended?
Solution: A grade 2 hamstring strain involves a significant tear within the muscle resulting in moderate to
severe pain and loss of function. The typical recovery time for a grade 2 hamstring strain in a football player
ranges from 4 to 8 weeks, depending on the extent of the injury and individual healing factors. Therefore,
the recommended recovery time for a grade 2 hamstring strain is approximately 6 weeks.
Answer: 6 weeks
18. Question: An athlete presents with a suspected ankle sprain after a basketball game. A radiograph
of the ankle reveals a lateral malleolus avulsion fracture measuring 5mm in displacement. According to the
Ottawa ankle rules, what is the maximum acceptable displacement for a lateral malleolus avulsion fracture
without requiring further imaging like a CT scan?
Solution: According to the Ottawa ankle rules, for avulsion fractures of the lateral malleolus on ankle
radiographs, the maximum acceptable displacement allowed without needing further imaging is 2mm. In
this case, the 5mm displacement exceeds the threshold, indicating the need for further imaging like a CT
scan.
19. Question: A basketball player experiences an injury to his ankle during a game. The player reports
that the pain started gradually over the past few weeks and has been persistent during games. Based on this
history, is the ankle injury more likely to be considered acute or chronic? Provide your answer in weeks.
Solution: Chronic injuries typically develop over a longer period, often weeks to months, and are char-
acterized by persistent or recurring pain or discomfort. In contrast, acute injuries occur suddenly and are
usually associated with a specific incident.
In this scenario, since the basketball player reports that the pain started gradually over the past few
weeks and has been persistent during games, the ankle injury is more likely to be considered chronic. The
injury has been ongoing for multiple weeks, indicating a longer development time associated with chronic
injuries. Therefore, the ankle injury is chronic and has been persisting for several weeks.
20. Question: A basketball player presents with sharp pain on the lateral aspect of their ankle following
a recent game. Upon assessment, you suspect either a lateral ankle sprain or a peroneal tendon injury. To
differentiate between the two, you perform the anterior drawer test and note that the talar tilt angle is 10
degrees. What is the most likely injury based on this information?
Solution: The anterior drawer test is used to assess the integrity of the anterior talofibular ligament
(ATFL) in cases of an ankle sprain. If the test is positive (indicating excessive anterior translation of the
talus on the tibia), it is suggestive of a ligamentous injury, such as a lateral ankle sprain. On the other
hand, the talar tilt test is used to assess instability related to the calcaneofibular ligament and the anterior
talofibular ligament. Typically, a talar tilt angle greater than 10 degrees is considered indicative of lateral
ankle instability, often seen in cases of lateral ankle sprains.
Therefore, based on the information provided and the talar tilt angle of 10 degrees, the most likely injury
is a lateral ankle sprain.
21. Question: A soccer player presents with sharp pain in the knee, especially when cutting and pivot-
ing. During the physical exam, the athletic trainer notes tenderness on the medial joint line and a positive
McMurray test. What is the most likely differential diagnosis in this case?
Solution: The symptoms described - sharp pain on the medial joint line, exacerbated with cutting and
a positive McMurray test - are indicative of a meniscal injury. Meniscal tears are common in sports that
involve cutting and pivoting movements like soccer. Therefore, the most likely differential diagnosis in this
case is a meniscal injury.
22. Question: What is the most common grade of ankle sprain in athletes based on lateral ligament
injuries assessment?
Solution: Grade 2 ankle sprain is the most common grade among athletes when assessing lateral liga-
ment injuries. This grade is characterized by partial tearing of the ligament, leading to moderate swelling,
bruising, and instability of the joint. Grade 2 ankle sprains usually require a longer recovery time compared
to Grade 1 sprains but have a better prognosis compared to Grade 3 sprains where the ligament is completely
torn.
23. Question: A basketball player presents with acute pain in the ankle after landing awkwardly from
a jump. On examination, there is tenderness and swelling around the lateral malleolus. The player has
difficulty bearing weight on the affected side. What is the most likely injury based on this presentation?
Solution: The presentation described is consistent with a lateral ankle sprain, which is a common sports-
related injury. The tenderness and swelling around the lateral malleolus, along with difficulty bearing
weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized
under the SCAT5 (Sport Concussion Assessment Tool 5) should be present at minimum to indicate a likely
concussion?
Solution: The SCAT5 consists of 22 symptoms, and according to the SCAT5 guidelines, if an athlete
presents with at least one of the 10 signs of this tool and at least one of the 22 symptoms, it may indicate a
likely concussion. Therefore, a minimum of two symptoms should be present to suggest a likely concussion.
25. Question: During a knee assessment, a sports medicine physician performs the anterior drawer test
to assess for anterior cruciate ligament (ACL) injury. The displacement of the tibia in millimeters from its
starting position to its furthest point is measured. If the physician notes a displacement of 8mm during the
anterior drawer test, how would you interpret this finding?
Solution: The anterior drawer test assesses the integrity of the ACL. A displacement of more than 6mm
in the anterior drawer test is indicative of a positive test for an ACL injury. In this case, with a displacement
of 8mm during the test, it suggests a positive finding for an ACL injury, indicating possible ligamentous
laxity and instability in the knee joint. Further imaging studies, such as MRI, might be warranted for a more
detailed evaluation and confirmation of the ACL injury.
5. Question: A basketball player presents with pain in the anterior knee that worsens with running,

traction tasks), and delayed recall (recalling the 5 words mentioned earlier). Therefore, the total number of
questions in the SAC test is 5 (orientation) + 5 (immediate memory) + 3 (concentration tasks) = 13 questions.
Answer: 13
9. Question: In a patient with a suspected ACL injury, an MRI scan reveals a tear of 1.5 cm in length. If
the total length of the ACL is considered to be 3.5 cm, what percentage of the ACL is affected by the tear?
Solution: To calculate the percentage of the ACL affected by the tear, we will use the formula: Percent-
age affected = (Length of tear / Total length of ACL) * 100
Given: Length of tear = 1.5 cm Total length of ACL = 3.5 cm
Substitute the given values into the formula: Percentage affected = (1.5 cm / 3.5 cm) * 100 Percentage
affected = (0.4286) * 100 Percentage affected 42.86
Therefore, the tear affects approximately 42.86
10. Question: A soccer player presents with pain in their knee after a match. Upon assessment, you

23. Question: A basketball player presents with acute pain in the ankle after landing awkwardly from
a jump. On examination, there is tenderness and swelling around the lateral malleolus. The player has
difficulty bearing weight on the affected side. What is the most likely injury based on this presentation?
Solution: The presentation described is consistent with a lateral ankle sprain, which is a common sports-
related injury. The tenderness and swelling around the lateral malleolus, along with difficulty bearing
weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized

Solution: The Glasgow Coma Scale (GCS) is used to assess the level of consciousness in a patient with
an acute brain injury, such as a concussion. The scale ranges from 3 to 15, with lower scores indicating
more severe brain injury. A GCS score of 8 or below is considered indicative of a severe brain injury. This
level of severity requires immediate medical attention and intervention.
8. Question: During a standardized sideline assessment for a suspected concussion in an athlete, how
many total questions are typically included in the Standardized Assessment of Concussion (SAC) test?
Solution: The Standardized Assessment of Concussion (SAC) test includes the following components:
orientation questions (5 questions), immediate memory (5 words to remember), concentration (serial sub-
traction tasks), and delayed recall (recalling the 5 words mentioned earlier). Therefore, the total number of
questions in the SAC test is 5 (orientation) + 5 (immediate memory) + 3 (concentration tasks) = 13 questions.
Answer: 13
9. Question: In a patient with a suspected ACL injury, an MRI scan reveals a tear of 1.5 cm in length. If
the total length of the ACL is considered to be 3.5 cm, what percentage of the ACL is affected by the tear?
Solution: To calculate the percentage of the ACL affected by the tear, we will use the formula: Percent-
age affected = (Length of tear / Total length of ACL) * 100
Given: Length of tear = 1.5 cm Total length of ACL = 3.5 cm
Substitute the given values into the formula: Percentage affected = (1.5 cm / 3.5 cm) * 100 Percentage
affected = (0.4286) * 100 Percentage affected 42.86
Therefore, the tear affects approximately 42.86
10. Question: A soccer player presents with pain in their knee after a match. Upon assessment, you
notice swelling, tenderness, and a history of gradual onset of pain over the past 4 weeks. Based on the
presentation, is this sports injury most likely acute or chronic?
Solution: - Acute injuries are typically sudden onset injuries due to an immediate trauma to the body.
Chronic injuries, on the other hand, develop over time due to repetitive stress or overuse.
- In this case, the soccer player’s history of gradual onset of pain over 4 weeks indicates a chronic injury.
Therefore, the sports injury in this scenario is most likely chronic.
11. Question:
During an assessment of an athlete’s ankle injury, the sports medicine professional conducts a Thompson
test to evaluate the integrity of the Achilles tendon. If the athlete’s ankle plantarflexes by 0 degrees compared
to the unaffected side during the test, what percentage of probability does this indicate of a complete Achilles
tendon rupture?
Solution:
A Thompson test is used to assess the integrity of the Achilles tendon, specifically to check for a com-
plete rupture. In a positive Thompson test (0 degrees of ankle plantarflexion), where there is no movement of
the foot in response to calf squeezing, it indicates a high probability of a complete Achilles tendon rupture.
Research indicates that a positive Thompson test has a high sensitivity and specificity for a complete
Achilles tendon rupture, with a likelihood ratio of around 30. This means that a positive test significantly
increases the probability of a complete tear.
Therefore, if the athlete’s ankle plantarflexes by 0 degrees during the Thompson test, it indicates almost
a 100
12. Question: A soccer player presents with pain in their knee that started gradually after increasing
their training intensity over the past few weeks. Upon assessment, the player reports tenderness along the
patellar tendon insertion and pain with running and jumping. Based on the presentation and assessment
findings, what type of sports injury is most likely occurring: acute or chronic? Provide your answer as a
numerical value: 1. Acute 2. Chronic
Solution: Chronic sports injuries develop over time due to repetitive overuse or stress on the body. The
gradual onset of pain after increasing training intensity and tenderness at the patellar tendon insertion point
in this scenario suggest a chronic injury related to overuse. Therefore, the most likely type of sports injury
occurring in this case is: 2. Chronic
13. Question: A basketball player presents with ankle pain after landing awkwardly during a game. The
pain developed suddenly and is localized to the lateral aspect of the ankle. The player reports a popping
sound at the time of injury. Based on this description, on a scale of 1 to 10, how likely is this injury to be
acute rather than chronic?
Solution: In this scenario, an acute injury is more probable due to the sudden onset of pain, localized
pain on the lateral aspect of the ankle (typical for an ankle sprain), and the player reporting a popping sound
which is often associated with ligamentous injury during an acute trauma. Acute injuries typically present
with immediate pain, swelling, and instability. Chronic injuries, on the other hand, develop over time due to
repetitive stress or overuse.
On a scale of 1 to 10, with 1 being very unlikely and 10 being highly likely, the likelihood of this injury
being acute rather than chronic would be around 9.
14. Question: A basketball player presents with symptoms of shoulder pain and limited range of motion.
During assessment, you perform the O’Brien’s Test for labral tears. If the player experiences pain at 90
degrees of shoulder flexion and internal rotation but no pain at 30 degrees of shoulder flexion and internal
rotation, what is the likelihood ratio for a labral tear based on this test result?
Solution: The likelihood ratio for a labral tear can be calculated using the following formula:
Likelihood Ratio =Sensitivity
1−Specificity
First, let’s determine the sensitivity and specificity of the O’Brien’s Test. Sensitivity is the ability of a test to
correctly identify those with the condition, and specificity is the ability of the test to correctly identify those
without the condition.
For the O’Brien’s Test: - Sensitivity: 95- Specificity: 80
Now we can plug in these values into the formula:
Likelihood Ratio =0.95
1−0.80 =0.95
0.20 = 4.75
Therefore, the likelihood ratio for a labral tear based on the O’Brien’s Test result in this case is 4.75.
15. Question: A basketball player presents with pain in the front of their knee and reports that the
symptoms started gradually after increasing their training intensity. On physical examination, they exhibit
tenderness over the inferior pole of the patella and pain with resisted knee extension. What is the most likely
diagnosis for this athlete?
Solution: The symptoms described are characteristic of patellar tendonitis, which is an overuse injury
commonly seen in athletes engaging in sports with repetitive jumping and running. The gradual onset
of symptoms, tenderness over the inferior pole of the patella, and pain with resisted knee extension are
all indicative of patellar tendonitis. To manage this condition, it is important to address the contributing
factors such as overtraining, poor biomechanics, or muscle imbalances through rest, activity modification,
stretching, strengthening exercises, and possibly physical therapy.
The numerical answer: Patellar tendonitis
16. Question: In the assessment of concussions in sports, what is the typical range of scores on the Sport
Concussion Assessment Tool (SCAT) that may indicate a potential concussion?
Solution: The Sport Concussion Assessment Tool (SCAT) is a standardized tool used to assess athletes
for concussions. One component of the SCAT is the Standardized Assessment of Concussion (SAC) portion,
where athletes are evaluated based on their cognitive function through a series of tasks. A typical range of
scores on the SAC portion of the SCAT that may indicate a potential concussion is between 25 to 30 points.
Scores lower than 25 are often considered indicative of a concussion, although it’s essential to evaluate other
factors in conjunction with the SAC score for an accurate diagnosis.
17. Question: In assessing a football player with a suspected grade 2 hamstring strain, how many weeks
of recovery time would typically be recommended?
Solution: A grade 2 hamstring strain involves a significant tear within the muscle resulting in moderate to
severe pain and loss of function. The typical recovery time for a grade 2 hamstring strain in a football player
ranges from 4 to 8 weeks, depending on the extent of the injury and individual healing factors. Therefore,
the recommended recovery time for a grade 2 hamstring strain is approximately 6 weeks.
Answer: 6 weeks
18. Question: An athlete presents with a suspected ankle sprain after a basketball game. A radiograph
of the ankle reveals a lateral malleolus avulsion fracture measuring 5mm in displacement. According to the
Ottawa ankle rules, what is the maximum acceptable displacement for a lateral malleolus avulsion fracture
without requiring further imaging like a CT scan?
Solution: According to the Ottawa ankle rules, for avulsion fractures of the lateral malleolus on ankle
radiographs, the maximum acceptable displacement allowed without needing further imaging is 2mm. In
this case, the 5mm displacement exceeds the threshold, indicating the need for further imaging like a CT
scan.
19. Question: A basketball player experiences an injury to his ankle during a game. The player reports
that the pain started gradually over the past few weeks and has been persistent during games. Based on this
history, is the ankle injury more likely to be considered acute or chronic? Provide your answer in weeks.
Solution: Chronic injuries typically develop over a longer period, often weeks to months, and are char-
acterized by persistent or recurring pain or discomfort. In contrast, acute injuries occur suddenly and are
usually associated with a specific incident.
In this scenario, since the basketball player reports that the pain started gradually over the past few
weeks and has been persistent during games, the ankle injury is more likely to be considered chronic. The
injury has been ongoing for multiple weeks, indicating a longer development time associated with chronic
injuries. Therefore, the ankle injury is chronic and has been persisting for several weeks.
20. Question: A basketball player presents with sharp pain on the lateral aspect of their ankle following
a recent game. Upon assessment, you suspect either a lateral ankle sprain or a peroneal tendon injury. To
differentiate between the two, you perform the anterior drawer test and note that the talar tilt angle is 10
degrees. What is the most likely injury based on this information?
Solution: The anterior drawer test is used to assess the integrity of the anterior talofibular ligament
(ATFL) in cases of an ankle sprain. If the test is positive (indicating excessive anterior translation of the
talus on the tibia), it is suggestive of a ligamentous injury, such as a lateral ankle sprain. On the other
hand, the talar tilt test is used to assess instability related to the calcaneofibular ligament and the anterior
talofibular ligament. Typically, a talar tilt angle greater than 10 degrees is considered indicative of lateral
ankle instability, often seen in cases of lateral ankle sprains.
Therefore, based on the information provided and the talar tilt angle of 10 degrees, the most likely injury
is a lateral ankle sprain.
21. Question: A soccer player presents with sharp pain in the knee, especially when cutting and pivot-
ing. During the physical exam, the athletic trainer notes tenderness on the medial joint line and a positive
McMurray test. What is the most likely differential diagnosis in this case?
Solution: The symptoms described - sharp pain on the medial joint line, exacerbated with cutting and
a positive McMurray test - are indicative of a meniscal injury. Meniscal tears are common in sports that
involve cutting and pivoting movements like soccer. Therefore, the most likely differential diagnosis in this
case is a meniscal injury.
22. Question: What is the most common grade of ankle sprain in athletes based on lateral ligament
injuries assessment?
Solution: Grade 2 ankle sprain is the most common grade among athletes when assessing lateral liga-
ment injuries. This grade is characterized by partial tearing of the ligament, leading to moderate swelling,
bruising, and instability of the joint. Grade 2 ankle sprains usually require a longer recovery time compared
to Grade 1 sprains but have a better prognosis compared to Grade 3 sprains where the ligament is completely
torn.
23. Question: A basketball player presents with acute pain in the ankle after landing awkwardly from
a jump. On examination, there is tenderness and swelling around the lateral malleolus. The player has
difficulty bearing weight on the affected side. What is the most likely injury based on this presentation?
Solution: The presentation described is consistent with a lateral ankle sprain, which is a common sports-
related injury. The tenderness and swelling around the lateral malleolus, along with difficulty bearing
weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized
under the SCAT5 (Sport Concussion Assessment Tool 5) should be present at minimum to indicate a likely
concussion?
Solution: The SCAT5 consists of 22 symptoms, and according to the SCAT5 guidelines, if an athlete
presents with at least one of the 10 signs of this tool and at least one of the 22 symptoms, it may indicate a
likely concussion. Therefore, a minimum of two symptoms should be present to suggest a likely concussion.
25. Question: During a knee assessment, a sports medicine physician performs the anterior drawer test
to assess for anterior cruciate ligament (ACL) injury. The displacement of the tibia in millimeters from its
starting position to its furthest point is measured. If the physician notes a displacement of 8mm during the
anterior drawer test, how would you interpret this finding?
Solution: The anterior drawer test assesses the integrity of the ACL. A displacement of more than 6mm
in the anterior drawer test is indicative of a positive test for an ACL injury. In this case, with a displacement
of 8mm during the test, it suggests a positive finding for an ACL injury, indicating possible ligamentous
laxity and instability in the knee joint. Further imaging studies, such as MRI, might be warranted for a more
detailed evaluation and confirmation of the ACL injury.
5. Question: A basketball player presents with pain in the anterior knee that worsens with running,
jumping, and cutting movements. Upon assessment, the athletic trainer notes tenderness at the inferior
pole of the patella, along with pain during resisted knee extension. The player reports that the pain started
gradually and has been persistent for the past 6 weeks. Based on these findings, what is the most likely
diagnosis?
Solution: The description provided aligns with the signs and symptoms of patellar tendinopathy, com-
monly known as jumper’s knee. This condition is characterized by pain and tenderness at the inferior pole
of the patella, especially with activities that involve repetitive jumping, running, or cutting movements. The
gradual onset and persistence of symptoms over 6 weeks further support this diagnosis.
Numerical Answer: Patellar tendinopathy
6. Question: In the assessment of a concussion in an athletic injury, how many key symptoms must be
present to diagnose a concussion according to the Sport Concussion Assessment Tool (SCAT-5)?
Solution: According to the Sport Concussion Assessment Tool (SCAT-5), the diagnosis of a concussion
is based on the presence of at least 1 of 22 key symptoms. So, the numerical answer is 1 symptom.
7. Question: During a concussion assessment, which numerical value on the Glasgow Coma Scale
would indicate a severe brain injury?
Solution: The Glasgow Coma Scale (GCS) is used to assess the level of consciousness in a patient with
an acute brain injury, such as a concussion. The scale ranges from 3 to 15, with lower scores indicating
more severe brain injury. A GCS score of 8 or below is considered indicative of a severe brain injury. This
level of severity requires immediate medical attention and intervention.
8. Question: During a standardized sideline assessment for a suspected concussion in an athlete, how
many total questions are typically included in the Standardized Assessment of Concussion (SAC) test?
Solution: The Standardized Assessment of Concussion (SAC) test includes the following components:
orientation questions (5 questions), immediate memory (5 words to remember), concentration (serial sub-
traction tasks), and delayed recall (recalling the 5 words mentioned earlier). Therefore, the total number of
questions in the SAC test is 5 (orientation) + 5 (immediate memory) + 3 (concentration tasks) = 13 questions.
Answer: 13
9. Question: In a patient with a suspected ACL injury, an MRI scan reveals a tear of 1.5 cm in length. If
the total length of the ACL is considered to be 3.5 cm, what percentage of the ACL is affected by the tear?
Solution: To calculate the percentage of the ACL affected by the tear, we will use the formula: Percent-
age affected = (Length of tear / Total length of ACL) * 100
Given: Length of tear = 1.5 cm Total length of ACL = 3.5 cm
Substitute the given values into the formula: Percentage affected = (1.5 cm / 3.5 cm) * 100 Percentage
affected = (0.4286) * 100 Percentage affected 42.86
Therefore, the tear affects approximately 42.86
10. Question: A soccer player presents with pain in their knee after a match. Upon assessment, you
notice swelling, tenderness, and a history of gradual onset of pain over the past 4 weeks. Based on the
presentation, is this sports injury most likely acute or chronic?
Solution: - Acute injuries are typically sudden onset injuries due to an immediate trauma to the body.
Chronic injuries, on the other hand, develop over time due to repetitive stress or overuse.
- In this case, the soccer player’s history of gradual onset of pain over 4 weeks indicates a chronic injury.

Solution: - Acute injuries are typically sudden onset injuries due to an immediate trauma to the body.
Chronic injuries, on the other hand, develop over time due to repetitive stress or overuse.
- In this case, the soccer player’s history of gradual onset of pain over 4 weeks indicates a chronic injury.
Therefore, the sports injury in this scenario is most likely chronic.
11. Question:
During an assessment of an athlete’s ankle injury, the sports medicine professional conducts a Thompson
test to evaluate the integrity of the Achilles tendon. If the athlete’s ankle plantarflexes by 0 degrees compared
to the unaffected side during the test, what percentage of probability does this indicate of a complete Achilles
tendon rupture?
Solution:
A Thompson test is used to assess the integrity of the Achilles tendon, specifically to check for a com-
plete rupture. In a positive Thompson test (0 degrees of ankle plantarflexion), where there is no movement of
the foot in response to calf squeezing, it indicates a high probability of a complete Achilles tendon rupture.
Research indicates that a positive Thompson test has a high sensitivity and specificity for a complete
Achilles tendon rupture, with a likelihood ratio of around 30. This means that a positive test significantly
increases the probability of a complete tear.
Therefore, if the athlete’s ankle plantarflexes by 0 degrees during the Thompson test, it indicates almost
a 100
12. Question: A soccer player presents with pain in their knee that started gradually after increasing
their training intensity over the past few weeks. Upon assessment, the player reports tenderness along the
patellar tendon insertion and pain with running and jumping. Based on the presentation and assessment
findings, what type of sports injury is most likely occurring: acute or chronic? Provide your answer as a
numerical value: 1. Acute 2. Chronic
Solution: Chronic sports injuries develop over time due to repetitive overuse or stress on the body. The
gradual onset of pain after increasing training intensity and tenderness at the patellar tendon insertion point
in this scenario suggest a chronic injury related to overuse. Therefore, the most likely type of sports injury
occurring in this case is: 2. Chronic
13. Question: A basketball player presents with ankle pain after landing awkwardly during a game. The
pain developed suddenly and is localized to the lateral aspect of the ankle. The player reports a popping
sound at the time of injury. Based on this description, on a scale of 1 to 10, how likely is this injury to be
acute rather than chronic?
Solution: In this scenario, an acute injury is more probable due to the sudden onset of pain, localized
pain on the lateral aspect of the ankle (typical for an ankle sprain), and the player reporting a popping sound
which is often associated with ligamentous injury during an acute trauma. Acute injuries typically present
with immediate pain, swelling, and instability. Chronic injuries, on the other hand, develop over time due to
repetitive stress or overuse.
On a scale of 1 to 10, with 1 being very unlikely and 10 being highly likely, the likelihood of this injury
being acute rather than chronic would be around 9.
14. Question: A basketball player presents with symptoms of shoulder pain and limited range of motion.
During assessment, you perform the O’Brien’s Test for labral tears. If the player experiences pain at 90
degrees of shoulder flexion and internal rotation but no pain at 30 degrees of shoulder flexion and internal
rotation, what is the likelihood ratio for a labral tear based on this test result?
Solution: The likelihood ratio for a labral tear can be calculated using the following formula:
Likelihood Ratio =Sensitivity
1−Specificity
First, let’s determine the sensitivity and specificity of the O’Brien’s Test. Sensitivity is the ability of a test to
correctly identify those with the condition, and specificity is the ability of the test to correctly identify those
without the condition.
For the O’Brien’s Test: - Sensitivity: 95- Specificity: 80
Now we can plug in these values into the formula:
Likelihood Ratio =0.95
1−0.80 =0.95
0.20 = 4.75
Therefore, the likelihood ratio for a labral tear based on the O’Brien’s Test result in this case is 4.75.
15. Question: A basketball player presents with pain in the front of their knee and reports that the
symptoms started gradually after increasing their training intensity. On physical examination, they exhibit
tenderness over the inferior pole of the patella and pain with resisted knee extension. What is the most likely
diagnosis for this athlete?
Solution: The symptoms described are characteristic of patellar tendonitis, which is an overuse injury
commonly seen in athletes engaging in sports with repetitive jumping and running. The gradual onset
of symptoms, tenderness over the inferior pole of the patella, and pain with resisted knee extension are
all indicative of patellar tendonitis. To manage this condition, it is important to address the contributing
factors such as overtraining, poor biomechanics, or muscle imbalances through rest, activity modification,
stretching, strengthening exercises, and possibly physical therapy.
The numerical answer: Patellar tendonitis
16. Question: In the assessment of concussions in sports, what is the typical range of scores on the Sport
Concussion Assessment Tool (SCAT) that may indicate a potential concussion?
Solution: The Sport Concussion Assessment Tool (SCAT) is a standardized tool used to assess athletes
for concussions. One component of the SCAT is the Standardized Assessment of Concussion (SAC) portion,
where athletes are evaluated based on their cognitive function through a series of tasks. A typical range of
scores on the SAC portion of the SCAT that may indicate a potential concussion is between 25 to 30 points.
Scores lower than 25 are often considered indicative of a concussion, although it’s essential to evaluate other
factors in conjunction with the SAC score for an accurate diagnosis.
17. Question: In assessing a football player with a suspected grade 2 hamstring strain, how many weeks
of recovery time would typically be recommended?
Solution: A grade 2 hamstring strain involves a significant tear within the muscle resulting in moderate to
severe pain and loss of function. The typical recovery time for a grade 2 hamstring strain in a football player
ranges from 4 to 8 weeks, depending on the extent of the injury and individual healing factors. Therefore,
the recommended recovery time for a grade 2 hamstring strain is approximately 6 weeks.
Answer: 6 weeks
18. Question: An athlete presents with a suspected ankle sprain after a basketball game. A radiograph
of the ankle reveals a lateral malleolus avulsion fracture measuring 5mm in displacement. According to the
Ottawa ankle rules, what is the maximum acceptable displacement for a lateral malleolus avulsion fracture
without requiring further imaging like a CT scan?
Solution: According to the Ottawa ankle rules, for avulsion fractures of the lateral malleolus on ankle
radiographs, the maximum acceptable displacement allowed without needing further imaging is 2mm. In
this case, the 5mm displacement exceeds the threshold, indicating the need for further imaging like a CT
scan.
19. Question: A basketball player experiences an injury to his ankle during a game. The player reports
that the pain started gradually over the past few weeks and has been persistent during games. Based on this
history, is the ankle injury more likely to be considered acute or chronic? Provide your answer in weeks.
Solution: Chronic injuries typically develop over a longer period, often weeks to months, and are char-
acterized by persistent or recurring pain or discomfort. In contrast, acute injuries occur suddenly and are
usually associated with a specific incident.
In this scenario, since the basketball player reports that the pain started gradually over the past few
weeks and has been persistent during games, the ankle injury is more likely to be considered chronic. The
injury has been ongoing for multiple weeks, indicating a longer development time associated with chronic
injuries. Therefore, the ankle injury is chronic and has been persisting for several weeks.
20. Question: A basketball player presents with sharp pain on the lateral aspect of their ankle following
a recent game. Upon assessment, you suspect either a lateral ankle sprain or a peroneal tendon injury. To
differentiate between the two, you perform the anterior drawer test and note that the talar tilt angle is 10
degrees. What is the most likely injury based on this information?
Solution: The anterior drawer test is used to assess the integrity of the anterior talofibular ligament
(ATFL) in cases of an ankle sprain. If the test is positive (indicating excessive anterior translation of the
talus on the tibia), it is suggestive of a ligamentous injury, such as a lateral ankle sprain. On the other
hand, the talar tilt test is used to assess instability related to the calcaneofibular ligament and the anterior
talofibular ligament. Typically, a talar tilt angle greater than 10 degrees is considered indicative of lateral
ankle instability, often seen in cases of lateral ankle sprains.
Therefore, based on the information provided and the talar tilt angle of 10 degrees, the most likely injury
is a lateral ankle sprain.
21. Question: A soccer player presents with sharp pain in the knee, especially when cutting and pivot-
ing. During the physical exam, the athletic trainer notes tenderness on the medial joint line and a positive
McMurray test. What is the most likely differential diagnosis in this case?
Solution: The symptoms described - sharp pain on the medial joint line, exacerbated with cutting and
a positive McMurray test - are indicative of a meniscal injury. Meniscal tears are common in sports that
involve cutting and pivoting movements like soccer. Therefore, the most likely differential diagnosis in this
case is a meniscal injury.
22. Question: What is the most common grade of ankle sprain in athletes based on lateral ligament
injuries assessment?
Solution: Grade 2 ankle sprain is the most common grade among athletes when assessing lateral liga-
ment injuries. This grade is characterized by partial tearing of the ligament, leading to moderate swelling,
bruising, and instability of the joint. Grade 2 ankle sprains usually require a longer recovery time compared
to Grade 1 sprains but have a better prognosis compared to Grade 3 sprains where the ligament is completely
torn.
23. Question: A basketball player presents with acute pain in the ankle after landing awkwardly from
a jump. On examination, there is tenderness and swelling around the lateral malleolus. The player has
difficulty bearing weight on the affected side. What is the most likely injury based on this presentation?
Solution: The presentation described is consistent with a lateral ankle sprain, which is a common sports-
related injury. The tenderness and swelling around the lateral malleolus, along with difficulty bearing
weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized
under the SCAT5 (Sport Concussion Assessment Tool 5) should be present at minimum to indicate a likely
concussion?
Solution: The SCAT5 consists of 22 symptoms, and according to the SCAT5 guidelines, if an athlete
presents with at least one of the 10 signs of this tool and at least one of the 22 symptoms, it may indicate a
likely concussion. Therefore, a minimum of two symptoms should be present to suggest a likely concussion.
25. Question: During a knee assessment, a sports medicine physician performs the anterior drawer test
to assess for anterior cruciate ligament (ACL) injury. The displacement of the tibia in millimeters from its
starting position to its furthest point is measured. If the physician notes a displacement of 8mm during the
anterior drawer test, how would you interpret this finding?
Solution: The anterior drawer test assesses the integrity of the ACL. A displacement of more than 6mm
in the anterior drawer test is indicative of a positive test for an ACL injury. In this case, with a displacement
of 8mm during the test, it suggests a positive finding for an ACL injury, indicating possible ligamentous
laxity and instability in the knee joint. Further imaging studies, such as MRI, might be warranted for a more
detailed evaluation and confirmation of the ACL injury.
5. Question: A basketball player presents with pain in the anterior knee that worsens with running,
jumping, and cutting movements. Upon assessment, the athletic trainer notes tenderness at the inferior
pole of the patella, along with pain during resisted knee extension. The player reports that the pain started
gradually and has been persistent for the past 6 weeks. Based on these findings, what is the most likely
diagnosis?
Solution: The description provided aligns with the signs and symptoms of patellar tendinopathy, com-
monly known as jumper’s knee. This condition is characterized by pain and tenderness at the inferior pole
of the patella, especially with activities that involve repetitive jumping, running, or cutting movements. The
gradual onset and persistence of symptoms over 6 weeks further support this diagnosis.
Numerical Answer: Patellar tendinopathy
6. Question: In the assessment of a concussion in an athletic injury, how many key symptoms must be
present to diagnose a concussion according to the Sport Concussion Assessment Tool (SCAT-5)?
Solution: According to the Sport Concussion Assessment Tool (SCAT-5), the diagnosis of a concussion
is based on the presence of at least 1 of 22 key symptoms. So, the numerical answer is 1 symptom.
7. Question: During a concussion assessment, which numerical value on the Glasgow Coma Scale
would indicate a severe brain injury?
Solution: The Glasgow Coma Scale (GCS) is used to assess the level of consciousness in a patient with
an acute brain injury, such as a concussion. The scale ranges from 3 to 15, with lower scores indicating
more severe brain injury. A GCS score of 8 or below is considered indicative of a severe brain injury. This
level of severity requires immediate medical attention and intervention.
8. Question: During a standardized sideline assessment for a suspected concussion in an athlete, how
many total questions are typically included in the Standardized Assessment of Concussion (SAC) test?
Solution: The Standardized Assessment of Concussion (SAC) test includes the following components:
orientation questions (5 questions), immediate memory (5 words to remember), concentration (serial sub-
traction tasks), and delayed recall (recalling the 5 words mentioned earlier). Therefore, the total number of
questions in the SAC test is 5 (orientation) + 5 (immediate memory) + 3 (concentration tasks) = 13 questions.
Answer: 13
9. Question: In a patient with a suspected ACL injury, an MRI scan reveals a tear of 1.5 cm in length. If
the total length of the ACL is considered to be 3.5 cm, what percentage of the ACL is affected by the tear?
Solution: To calculate the percentage of the ACL affected by the tear, we will use the formula: Percent-
age affected = (Length of tear / Total length of ACL) * 100
Given: Length of tear = 1.5 cm Total length of ACL = 3.5 cm
Substitute the given values into the formula: Percentage affected = (1.5 cm / 3.5 cm) * 100 Percentage
affected = (0.4286) * 100 Percentage affected 42.86
Therefore, the tear affects approximately 42.86
10. Question: A soccer player presents with pain in their knee after a match. Upon assessment, you
notice swelling, tenderness, and a history of gradual onset of pain over the past 4 weeks. Based on the
presentation, is this sports injury most likely acute or chronic?
Solution: - Acute injuries are typically sudden onset injuries due to an immediate trauma to the body.
Chronic injuries, on the other hand, develop over time due to repetitive stress or overuse.
- In this case, the soccer player’s history of gradual onset of pain over 4 weeks indicates a chronic injury.
Therefore, the sports injury in this scenario is most likely chronic.

weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized

12. Question: A soccer player presents with pain in their knee that started gradually after increasing
their training intensity over the past few weeks. Upon assessment, the player reports tenderness along the
patellar tendon insertion and pain with running and jumping. Based on the presentation and assessment
findings, what type of sports injury is most likely occurring: acute or chronic? Provide your answer as a
numerical value: 1. Acute 2. Chronic
Solution: Chronic sports injuries develop over time due to repetitive overuse or stress on the body. The
gradual onset of pain after increasing training intensity and tenderness at the patellar tendon insertion point
in this scenario suggest a chronic injury related to overuse. Therefore, the most likely type of sports injury
occurring in this case is: 2. Chronic
13. Question: A basketball player presents with ankle pain after landing awkwardly during a game. The
pain developed suddenly and is localized to the lateral aspect of the ankle. The player reports a popping
sound at the time of injury. Based on this description, on a scale of 1 to 10, how likely is this injury to be
acute rather than chronic?
Solution: In this scenario, an acute injury is more probable due to the sudden onset of pain, localized
pain on the lateral aspect of the ankle (typical for an ankle sprain), and the player reporting a popping sound
which is often associated with ligamentous injury during an acute trauma. Acute injuries typically present
with immediate pain, swelling, and instability. Chronic injuries, on the other hand, develop over time due to
repetitive stress or overuse.
On a scale of 1 to 10, with 1 being very unlikely and 10 being highly likely, the likelihood of this injury
being acute rather than chronic would be around 9.
14. Question: A basketball player presents with symptoms of shoulder pain and limited range of motion.
During assessment, you perform the O’Brien’s Test for labral tears. If the player experiences pain at 90
degrees of shoulder flexion and internal rotation but no pain at 30 degrees of shoulder flexion and internal
rotation, what is the likelihood ratio for a labral tear based on this test result?
Solution: The likelihood ratio for a labral tear can be calculated using the following formula:
Likelihood Ratio =Sensitivity
1−Specificity
First, let’s determine the sensitivity and specificity of the O’Brien’s Test. Sensitivity is the ability of a test to
correctly identify those with the condition, and specificity is the ability of the test to correctly identify those
without the condition.
For the O’Brien’s Test: - Sensitivity: 95- Specificity: 80
Now we can plug in these values into the formula:
Likelihood Ratio =0.95
1−0.80 =0.95
0.20 = 4.75
Therefore, the likelihood ratio for a labral tear based on the O’Brien’s Test result in this case is 4.75.
15. Question: A basketball player presents with pain in the front of their knee and reports that the
symptoms started gradually after increasing their training intensity. On physical examination, they exhibit
tenderness over the inferior pole of the patella and pain with resisted knee extension. What is the most likely
diagnosis for this athlete?
Solution: The symptoms described are characteristic of patellar tendonitis, which is an overuse injury
commonly seen in athletes engaging in sports with repetitive jumping and running. The gradual onset
of symptoms, tenderness over the inferior pole of the patella, and pain with resisted knee extension are
all indicative of patellar tendonitis. To manage this condition, it is important to address the contributing
factors such as overtraining, poor biomechanics, or muscle imbalances through rest, activity modification,
stretching, strengthening exercises, and possibly physical therapy.
The numerical answer: Patellar tendonitis
16. Question: In the assessment of concussions in sports, what is the typical range of scores on the Sport
Concussion Assessment Tool (SCAT) that may indicate a potential concussion?
Solution: The Sport Concussion Assessment Tool (SCAT) is a standardized tool used to assess athletes
for concussions. One component of the SCAT is the Standardized Assessment of Concussion (SAC) portion,
where athletes are evaluated based on their cognitive function through a series of tasks. A typical range of
scores on the SAC portion of the SCAT that may indicate a potential concussion is between 25 to 30 points.
Scores lower than 25 are often considered indicative of a concussion, although it’s essential to evaluate other
factors in conjunction with the SAC score for an accurate diagnosis.
17. Question: In assessing a football player with a suspected grade 2 hamstring strain, how many weeks
of recovery time would typically be recommended?
Solution: A grade 2 hamstring strain involves a significant tear within the muscle resulting in moderate to
severe pain and loss of function. The typical recovery time for a grade 2 hamstring strain in a football player
ranges from 4 to 8 weeks, depending on the extent of the injury and individual healing factors. Therefore,
the recommended recovery time for a grade 2 hamstring strain is approximately 6 weeks.
Answer: 6 weeks
18. Question: An athlete presents with a suspected ankle sprain after a basketball game. A radiograph
of the ankle reveals a lateral malleolus avulsion fracture measuring 5mm in displacement. According to the
Ottawa ankle rules, what is the maximum acceptable displacement for a lateral malleolus avulsion fracture
without requiring further imaging like a CT scan?
Solution: According to the Ottawa ankle rules, for avulsion fractures of the lateral malleolus on ankle
radiographs, the maximum acceptable displacement allowed without needing further imaging is 2mm. In
this case, the 5mm displacement exceeds the threshold, indicating the need for further imaging like a CT
scan.
19. Question: A basketball player experiences an injury to his ankle during a game. The player reports
that the pain started gradually over the past few weeks and has been persistent during games. Based on this
history, is the ankle injury more likely to be considered acute or chronic? Provide your answer in weeks.
Solution: Chronic injuries typically develop over a longer period, often weeks to months, and are char-
acterized by persistent or recurring pain or discomfort. In contrast, acute injuries occur suddenly and are
usually associated with a specific incident.
In this scenario, since the basketball player reports that the pain started gradually over the past few
weeks and has been persistent during games, the ankle injury is more likely to be considered chronic. The
injury has been ongoing for multiple weeks, indicating a longer development time associated with chronic
injuries. Therefore, the ankle injury is chronic and has been persisting for several weeks.
20. Question: A basketball player presents with sharp pain on the lateral aspect of their ankle following
a recent game. Upon assessment, you suspect either a lateral ankle sprain or a peroneal tendon injury. To
differentiate between the two, you perform the anterior drawer test and note that the talar tilt angle is 10
degrees. What is the most likely injury based on this information?
Solution: The anterior drawer test is used to assess the integrity of the anterior talofibular ligament
(ATFL) in cases of an ankle sprain. If the test is positive (indicating excessive anterior translation of the
talus on the tibia), it is suggestive of a ligamentous injury, such as a lateral ankle sprain. On the other
hand, the talar tilt test is used to assess instability related to the calcaneofibular ligament and the anterior
talofibular ligament. Typically, a talar tilt angle greater than 10 degrees is considered indicative of lateral
ankle instability, often seen in cases of lateral ankle sprains.
Therefore, based on the information provided and the talar tilt angle of 10 degrees, the most likely injury
is a lateral ankle sprain.
21. Question: A soccer player presents with sharp pain in the knee, especially when cutting and pivot-
ing. During the physical exam, the athletic trainer notes tenderness on the medial joint line and a positive
McMurray test. What is the most likely differential diagnosis in this case?
Solution: The symptoms described - sharp pain on the medial joint line, exacerbated with cutting and
a positive McMurray test - are indicative of a meniscal injury. Meniscal tears are common in sports that
involve cutting and pivoting movements like soccer. Therefore, the most likely differential diagnosis in this
case is a meniscal injury.
22. Question: What is the most common grade of ankle sprain in athletes based on lateral ligament
injuries assessment?
Solution: Grade 2 ankle sprain is the most common grade among athletes when assessing lateral liga-
ment injuries. This grade is characterized by partial tearing of the ligament, leading to moderate swelling,
bruising, and instability of the joint. Grade 2 ankle sprains usually require a longer recovery time compared
to Grade 1 sprains but have a better prognosis compared to Grade 3 sprains where the ligament is completely
torn.
23. Question: A basketball player presents with acute pain in the ankle after landing awkwardly from
a jump. On examination, there is tenderness and swelling around the lateral malleolus. The player has
difficulty bearing weight on the affected side. What is the most likely injury based on this presentation?
Solution: The presentation described is consistent with a lateral ankle sprain, which is a common sports-
related injury. The tenderness and swelling around the lateral malleolus, along with difficulty bearing
weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized
under the SCAT5 (Sport Concussion Assessment Tool 5) should be present at minimum to indicate a likely
concussion?
Solution: The SCAT5 consists of 22 symptoms, and according to the SCAT5 guidelines, if an athlete
presents with at least one of the 10 signs of this tool and at least one of the 22 symptoms, it may indicate a
likely concussion. Therefore, a minimum of two symptoms should be present to suggest a likely concussion.
25. Question: During a knee assessment, a sports medicine physician performs the anterior drawer test
to assess for anterior cruciate ligament (ACL) injury. The displacement of the tibia in millimeters from its
starting position to its furthest point is measured. If the physician notes a displacement of 8mm during the
anterior drawer test, how would you interpret this finding?
Solution: The anterior drawer test assesses the integrity of the ACL. A displacement of more than 6mm
in the anterior drawer test is indicative of a positive test for an ACL injury. In this case, with a displacement
of 8mm during the test, it suggests a positive finding for an ACL injury, indicating possible ligamentous
laxity and instability in the knee joint. Further imaging studies, such as MRI, might be warranted for a more
detailed evaluation and confirmation of the ACL injury.
5. Question: A basketball player presents with pain in the anterior knee that worsens with running,
jumping, and cutting movements. Upon assessment, the athletic trainer notes tenderness at the inferior
pole of the patella, along with pain during resisted knee extension. The player reports that the pain started
gradually and has been persistent for the past 6 weeks. Based on these findings, what is the most likely
diagnosis?
Solution: The description provided aligns with the signs and symptoms of patellar tendinopathy, com-
monly known as jumper’s knee. This condition is characterized by pain and tenderness at the inferior pole
of the patella, especially with activities that involve repetitive jumping, running, or cutting movements. The
gradual onset and persistence of symptoms over 6 weeks further support this diagnosis.
Numerical Answer: Patellar tendinopathy
6. Question: In the assessment of a concussion in an athletic injury, how many key symptoms must be
present to diagnose a concussion according to the Sport Concussion Assessment Tool (SCAT-5)?
Solution: According to the Sport Concussion Assessment Tool (SCAT-5), the diagnosis of a concussion
is based on the presence of at least 1 of 22 key symptoms. So, the numerical answer is 1 symptom.
7. Question: During a concussion assessment, which numerical value on the Glasgow Coma Scale
would indicate a severe brain injury?
Solution: The Glasgow Coma Scale (GCS) is used to assess the level of consciousness in a patient with
an acute brain injury, such as a concussion. The scale ranges from 3 to 15, with lower scores indicating
more severe brain injury. A GCS score of 8 or below is considered indicative of a severe brain injury. This
level of severity requires immediate medical attention and intervention.
8. Question: During a standardized sideline assessment for a suspected concussion in an athlete, how
many total questions are typically included in the Standardized Assessment of Concussion (SAC) test?
Solution: The Standardized Assessment of Concussion (SAC) test includes the following components:
orientation questions (5 questions), immediate memory (5 words to remember), concentration (serial sub-
traction tasks), and delayed recall (recalling the 5 words mentioned earlier). Therefore, the total number of
questions in the SAC test is 5 (orientation) + 5 (immediate memory) + 3 (concentration tasks) = 13 questions.
Answer: 13
9. Question: In a patient with a suspected ACL injury, an MRI scan reveals a tear of 1.5 cm in length. If
the total length of the ACL is considered to be 3.5 cm, what percentage of the ACL is affected by the tear?
Solution: To calculate the percentage of the ACL affected by the tear, we will use the formula: Percent-
age affected = (Length of tear / Total length of ACL) * 100
Given: Length of tear = 1.5 cm Total length of ACL = 3.5 cm
Substitute the given values into the formula: Percentage affected = (1.5 cm / 3.5 cm) * 100 Percentage
affected = (0.4286) * 100 Percentage affected 42.86
Therefore, the tear affects approximately 42.86
10. Question: A soccer player presents with pain in their knee after a match. Upon assessment, you
notice swelling, tenderness, and a history of gradual onset of pain over the past 4 weeks. Based on the
presentation, is this sports injury most likely acute or chronic?
Solution: - Acute injuries are typically sudden onset injuries due to an immediate trauma to the body.
Chronic injuries, on the other hand, develop over time due to repetitive stress or overuse.
- In this case, the soccer player’s history of gradual onset of pain over 4 weeks indicates a chronic injury.
Therefore, the sports injury in this scenario is most likely chronic.
11. Question:
During an assessment of an athlete’s ankle injury, the sports medicine professional conducts a Thompson
test to evaluate the integrity of the Achilles tendon. If the athlete’s ankle plantarflexes by 0 degrees compared
to the unaffected side during the test, what percentage of probability does this indicate of a complete Achilles
tendon rupture?
Solution:
A Thompson test is used to assess the integrity of the Achilles tendon, specifically to check for a com-
plete rupture. In a positive Thompson test (0 degrees of ankle plantarflexion), where there is no movement of
the foot in response to calf squeezing, it indicates a high probability of a complete Achilles tendon rupture.
Research indicates that a positive Thompson test has a high sensitivity and specificity for a complete
Achilles tendon rupture, with a likelihood ratio of around 30. This means that a positive test significantly
increases the probability of a complete tear.
Therefore, if the athlete’s ankle plantarflexes by 0 degrees during the Thompson test, it indicates almost
a 100
12. Question: A soccer player presents with pain in their knee that started gradually after increasing
their training intensity over the past few weeks. Upon assessment, the player reports tenderness along the
patellar tendon insertion and pain with running and jumping. Based on the presentation and assessment
findings, what type of sports injury is most likely occurring: acute or chronic? Provide your answer as a
numerical value: 1. Acute 2. Chronic
Solution: Chronic sports injuries develop over time due to repetitive overuse or stress on the body. The
gradual onset of pain after increasing training intensity and tenderness at the patellar tendon insertion point
in this scenario suggest a chronic injury related to overuse. Therefore, the most likely type of sports injury
occurring in this case is: 2. Chronic
13. Question: A basketball player presents with ankle pain after landing awkwardly during a game. The
pain developed suddenly and is localized to the lateral aspect of the ankle. The player reports a popping
sound at the time of injury. Based on this description, on a scale of 1 to 10, how likely is this injury to be
acute rather than chronic?
Solution: In this scenario, an acute injury is more probable due to the sudden onset of pain, localized
pain on the lateral aspect of the ankle (typical for an ankle sprain), and the player reporting a popping sound
which is often associated with ligamentous injury during an acute trauma. Acute injuries typically present
with immediate pain, swelling, and instability. Chronic injuries, on the other hand, develop over time due to
repetitive stress or overuse.
On a scale of 1 to 10, with 1 being very unlikely and 10 being highly likely, the likelihood of this injury
being acute rather than chronic would be around 9.

Now we can plug in these values into the formula:
Likelihood Ratio =0.95
1−0.80 =0.95
0.20 = 4.75
Therefore, the likelihood ratio for a labral tear based on the O’Brien’s Test result in this case is 4.75.

difficulty bearing weight on the affected side. What is the most likely injury based on this presentation?
Solution: The presentation described is consistent with a lateral ankle sprain, which is a common sports-
related injury. The tenderness and swelling around the lateral malleolus, along with difficulty bearing
weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized
under the SCAT5 (Sport Concussion Assessment Tool 5) should be present at minimum to indicate a likely

Solution: The SCAT5 consists of 22 symptoms, and according to the SCAT5 guidelines, if an athlete
presents with at least one of the 10 signs of this tool and at least one of the 22 symptoms, it may indicate a
likely concussion. Therefore, a minimum of two symptoms should be present to suggest a likely concussion.
25. Question: During a knee assessment, a sports medicine physician performs the anterior drawer test
to assess for anterior cruciate ligament (ACL) injury. The displacement of the tibia in millimeters from its
starting position to its furthest point is measured. If the physician notes a displacement of 8mm during the
anterior drawer test, how would you interpret this finding?
Solution: The anterior drawer test assesses the integrity of the ACL. A displacement of more than 6mm
in the anterior drawer test is indicative of a positive test for an ACL injury. In this case, with a displacement
of 8mm during the test, it suggests a positive finding for an ACL injury, indicating possible ligamentous
laxity and instability in the knee joint. Further imaging studies, such as MRI, might be warranted for a more
detailed evaluation and confirmation of the ACL injury.

where athletes are evaluated based on their cognitive function through a series of tasks. A typical range of
scores on the SAC portion of the SCAT that may indicate a potential concussion is between 25 to 30 points.
Scores lower than 25 are often considered indicative of a concussion, although it’s essential to evaluate other
factors in conjunction with the SAC score for an accurate diagnosis.
17. Question: In assessing a football player with a suspected grade 2 hamstring strain, how many weeks
of recovery time would typically be recommended?
Solution: A grade 2 hamstring strain involves a significant tear within the muscle resulting in moderate to
severe pain and loss of function. The typical recovery time for a grade 2 hamstring strain in a football player
ranges from 4 to 8 weeks, depending on the extent of the injury and individual healing factors. Therefore,
the recommended recovery time for a grade 2 hamstring strain is approximately 6 weeks.
Answer: 6 weeks
18. Question: An athlete presents with a suspected ankle sprain after a basketball game. A radiograph
of the ankle reveals a lateral malleolus avulsion fracture measuring 5mm in displacement. According to the
Ottawa ankle rules, what is the maximum acceptable displacement for a lateral malleolus avulsion fracture
without requiring further imaging like a CT scan?
Solution: According to the Ottawa ankle rules, for avulsion fractures of the lateral malleolus on ankle
radiographs, the maximum acceptable displacement allowed without needing further imaging is 2mm. In
this case, the 5mm displacement exceeds the threshold, indicating the need for further imaging like a CT
scan.
19. Question: A basketball player experiences an injury to his ankle during a game. The player reports
that the pain started gradually over the past few weeks and has been persistent during games. Based on this
history, is the ankle injury more likely to be considered acute or chronic? Provide your answer in weeks.
Solution: Chronic injuries typically develop over a longer period, often weeks to months, and are char-
acterized by persistent or recurring pain or discomfort. In contrast, acute injuries occur suddenly and are
usually associated with a specific incident.
In this scenario, since the basketball player reports that the pain started gradually over the past few
weeks and has been persistent during games, the ankle injury is more likely to be considered chronic. The
injury has been ongoing for multiple weeks, indicating a longer development time associated with chronic
injuries. Therefore, the ankle injury is chronic and has been persisting for several weeks.
20. Question: A basketball player presents with sharp pain on the lateral aspect of their ankle following
a recent game. Upon assessment, you suspect either a lateral ankle sprain or a peroneal tendon injury. To
differentiate between the two, you perform the anterior drawer test and note that the talar tilt angle is 10
degrees. What is the most likely injury based on this information?
Solution: The anterior drawer test is used to assess the integrity of the anterior talofibular ligament
(ATFL) in cases of an ankle sprain. If the test is positive (indicating excessive anterior translation of the
talus on the tibia), it is suggestive of a ligamentous injury, such as a lateral ankle sprain. On the other
hand, the talar tilt test is used to assess instability related to the calcaneofibular ligament and the anterior
talofibular ligament. Typically, a talar tilt angle greater than 10 degrees is considered indicative of lateral
ankle instability, often seen in cases of lateral ankle sprains.
Therefore, based on the information provided and the talar tilt angle of 10 degrees, the most likely injury
is a lateral ankle sprain.
21. Question: A soccer player presents with sharp pain in the knee, especially when cutting and pivot-
ing. During the physical exam, the athletic trainer notes tenderness on the medial joint line and a positive
McMurray test. What is the most likely differential diagnosis in this case?
Solution: The symptoms described - sharp pain on the medial joint line, exacerbated with cutting and
a positive McMurray test - are indicative of a meniscal injury. Meniscal tears are common in sports that
involve cutting and pivoting movements like soccer. Therefore, the most likely differential diagnosis in this
case is a meniscal injury.
22. Question: What is the most common grade of ankle sprain in athletes based on lateral ligament
injuries assessment?
Solution: Grade 2 ankle sprain is the most common grade among athletes when assessing lateral liga-
ment injuries. This grade is characterized by partial tearing of the ligament, leading to moderate swelling,
bruising, and instability of the joint. Grade 2 ankle sprains usually require a longer recovery time compared
to Grade 1 sprains but have a better prognosis compared to Grade 3 sprains where the ligament is completely
torn.
23. Question: A basketball player presents with acute pain in the ankle after landing awkwardly from
a jump. On examination, there is tenderness and swelling around the lateral malleolus. The player has
difficulty bearing weight on the affected side. What is the most likely injury based on this presentation?
Solution: The presentation described is consistent with a lateral ankle sprain, which is a common sports-
related injury. The tenderness and swelling around the lateral malleolus, along with difficulty bearing
weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized
under the SCAT5 (Sport Concussion Assessment Tool 5) should be present at minimum to indicate a likely
concussion?
Solution: The SCAT5 consists of 22 symptoms, and according to the SCAT5 guidelines, if an athlete
presents with at least one of the 10 signs of this tool and at least one of the 22 symptoms, it may indicate a
likely concussion. Therefore, a minimum of two symptoms should be present to suggest a likely concussion.
25. Question: During a knee assessment, a sports medicine physician performs the anterior drawer test
to assess for anterior cruciate ligament (ACL) injury. The displacement of the tibia in millimeters from its
starting position to its furthest point is measured. If the physician notes a displacement of 8mm during the
anterior drawer test, how would you interpret this finding?
Solution: The anterior drawer test assesses the integrity of the ACL. A displacement of more than 6mm
in the anterior drawer test is indicative of a positive test for an ACL injury. In this case, with a displacement
of 8mm during the test, it suggests a positive finding for an ACL injury, indicating possible ligamentous
laxity and instability in the knee joint. Further imaging studies, such as MRI, might be warranted for a more
detailed evaluation and confirmation of the ACL injury.
5. Question: A basketball player presents with pain in the anterior knee that worsens with running,
jumping, and cutting movements. Upon assessment, the athletic trainer notes tenderness at the inferior
pole of the patella, along with pain during resisted knee extension. The player reports that the pain started
gradually and has been persistent for the past 6 weeks. Based on these findings, what is the most likely
diagnosis?
Solution: The description provided aligns with the signs and symptoms of patellar tendinopathy, com-
monly known as jumper’s knee. This condition is characterized by pain and tenderness at the inferior pole
of the patella, especially with activities that involve repetitive jumping, running, or cutting movements. The
gradual onset and persistence of symptoms over 6 weeks further support this diagnosis.
Numerical Answer: Patellar tendinopathy
6. Question: In the assessment of a concussion in an athletic injury, how many key symptoms must be
present to diagnose a concussion according to the Sport Concussion Assessment Tool (SCAT-5)?
Solution: According to the Sport Concussion Assessment Tool (SCAT-5), the diagnosis of a concussion
is based on the presence of at least 1 of 22 key symptoms. So, the numerical answer is 1 symptom.
7. Question: During a concussion assessment, which numerical value on the Glasgow Coma Scale
would indicate a severe brain injury?
Solution: The Glasgow Coma Scale (GCS) is used to assess the level of consciousness in a patient with
an acute brain injury, such as a concussion. The scale ranges from 3 to 15, with lower scores indicating
more severe brain injury. A GCS score of 8 or below is considered indicative of a severe brain injury. This
level of severity requires immediate medical attention and intervention.
8. Question: During a standardized sideline assessment for a suspected concussion in an athlete, how
many total questions are typically included in the Standardized Assessment of Concussion (SAC) test?
Solution: The Standardized Assessment of Concussion (SAC) test includes the following components:
orientation questions (5 questions), immediate memory (5 words to remember), concentration (serial sub-
traction tasks), and delayed recall (recalling the 5 words mentioned earlier). Therefore, the total number of
questions in the SAC test is 5 (orientation) + 5 (immediate memory) + 3 (concentration tasks) = 13 questions.
Answer: 13
9. Question: In a patient with a suspected ACL injury, an MRI scan reveals a tear of 1.5 cm in length. If
the total length of the ACL is considered to be 3.5 cm, what percentage of the ACL is affected by the tear?
Solution: To calculate the percentage of the ACL affected by the tear, we will use the formula: Percent-
age affected = (Length of tear / Total length of ACL) * 100
Given: Length of tear = 1.5 cm Total length of ACL = 3.5 cm
Substitute the given values into the formula: Percentage affected = (1.5 cm / 3.5 cm) * 100 Percentage
affected = (0.4286) * 100 Percentage affected 42.86
Therefore, the tear affects approximately 42.86
10. Question: A soccer player presents with pain in their knee after a match. Upon assessment, you
notice swelling, tenderness, and a history of gradual onset of pain over the past 4 weeks. Based on the
presentation, is this sports injury most likely acute or chronic?
Solution: - Acute injuries are typically sudden onset injuries due to an immediate trauma to the body.
Chronic injuries, on the other hand, develop over time due to repetitive stress or overuse.
- In this case, the soccer player’s history of gradual onset of pain over 4 weeks indicates a chronic injury.
Therefore, the sports injury in this scenario is most likely chronic.
11. Question:
During an assessment of an athlete’s ankle injury, the sports medicine professional conducts a Thompson
test to evaluate the integrity of the Achilles tendon. If the athlete’s ankle plantarflexes by 0 degrees compared
to the unaffected side during the test, what percentage of probability does this indicate of a complete Achilles
tendon rupture?
Solution:
A Thompson test is used to assess the integrity of the Achilles tendon, specifically to check for a com-
plete rupture. In a positive Thompson test (0 degrees of ankle plantarflexion), where there is no movement of
the foot in response to calf squeezing, it indicates a high probability of a complete Achilles tendon rupture.
Research indicates that a positive Thompson test has a high sensitivity and specificity for a complete
Achilles tendon rupture, with a likelihood ratio of around 30. This means that a positive test significantly
increases the probability of a complete tear.
Therefore, if the athlete’s ankle plantarflexes by 0 degrees during the Thompson test, it indicates almost
a 100
12. Question: A soccer player presents with pain in their knee that started gradually after increasing
their training intensity over the past few weeks. Upon assessment, the player reports tenderness along the
patellar tendon insertion and pain with running and jumping. Based on the presentation and assessment
findings, what type of sports injury is most likely occurring: acute or chronic? Provide your answer as a
numerical value: 1. Acute 2. Chronic
Solution: Chronic sports injuries develop over time due to repetitive overuse or stress on the body. The
gradual onset of pain after increasing training intensity and tenderness at the patellar tendon insertion point
in this scenario suggest a chronic injury related to overuse. Therefore, the most likely type of sports injury
occurring in this case is: 2. Chronic
13. Question: A basketball player presents with ankle pain after landing awkwardly during a game. The
pain developed suddenly and is localized to the lateral aspect of the ankle. The player reports a popping
sound at the time of injury. Based on this description, on a scale of 1 to 10, how likely is this injury to be
acute rather than chronic?
Solution: In this scenario, an acute injury is more probable due to the sudden onset of pain, localized
pain on the lateral aspect of the ankle (typical for an ankle sprain), and the player reporting a popping sound
which is often associated with ligamentous injury during an acute trauma. Acute injuries typically present
with immediate pain, swelling, and instability. Chronic injuries, on the other hand, develop over time due to
repetitive stress or overuse.
On a scale of 1 to 10, with 1 being very unlikely and 10 being highly likely, the likelihood of this injury
being acute rather than chronic would be around 9.
14. Question: A basketball player presents with symptoms of shoulder pain and limited range of motion.
During assessment, you perform the O’Brien’s Test for labral tears. If the player experiences pain at 90
degrees of shoulder flexion and internal rotation but no pain at 30 degrees of shoulder flexion and internal
rotation, what is the likelihood ratio for a labral tear based on this test result?
Solution: The likelihood ratio for a labral tear can be calculated using the following formula:
Likelihood Ratio =Sensitivity
1−Specificity
First, let’s determine the sensitivity and specificity of the O’Brien’s Test. Sensitivity is the ability of a test to
correctly identify those with the condition, and specificity is the ability of the test to correctly identify those
without the condition.
For the O’Brien’s Test: - Sensitivity: 95- Specificity: 80
Now we can plug in these values into the formula:
Likelihood Ratio =0.95
1−0.80 =0.95
0.20 = 4.75
Therefore, the likelihood ratio for a labral tear based on the O’Brien’s Test result in this case is 4.75.
15. Question: A basketball player presents with pain in the front of their knee and reports that the
symptoms started gradually after increasing their training intensity. On physical examination, they exhibit
tenderness over the inferior pole of the patella and pain with resisted knee extension. What is the most likely
diagnosis for this athlete?
Solution: The symptoms described are characteristic of patellar tendonitis, which is an overuse injury
commonly seen in athletes engaging in sports with repetitive jumping and running. The gradual onset
of symptoms, tenderness over the inferior pole of the patella, and pain with resisted knee extension are
all indicative of patellar tendonitis. To manage this condition, it is important to address the contributing
factors such as overtraining, poor biomechanics, or muscle imbalances through rest, activity modification,
stretching, strengthening exercises, and possibly physical therapy.
The numerical answer: Patellar tendonitis
16. Question: In the assessment of concussions in sports, what is the typical range of scores on the Sport
Concussion Assessment Tool (SCAT) that may indicate a potential concussion?
Solution: The Sport Concussion Assessment Tool (SCAT) is a standardized tool used to assess athletes
for concussions. One component of the SCAT is the Standardized Assessment of Concussion (SAC) portion,
where athletes are evaluated based on their cognitive function through a series of tasks. A typical range of
scores on the SAC portion of the SCAT that may indicate a potential concussion is between 25 to 30 points.
Scores lower than 25 are often considered indicative of a concussion, although it’s essential to evaluate other
factors in conjunction with the SAC score for an accurate diagnosis.
17. Question: In assessing a football player with a suspected grade 2 hamstring strain, how many weeks

weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized

that the pain started gradually over the past few weeks and has been persistent during games. Based on this
history, is the ankle injury more likely to be considered acute or chronic? Provide your answer in weeks.
Solution: Chronic injuries typically develop over a longer period, often weeks to months, and are char-
acterized by persistent or recurring pain or discomfort. In contrast, acute injuries occur suddenly and are
usually associated with a specific incident.
In this scenario, since the basketball player reports that the pain started gradually over the past few
weeks and has been persistent during games, the ankle injury is more likely to be considered chronic. The
injury has been ongoing for multiple weeks, indicating a longer development time associated with chronic
injuries. Therefore, the ankle injury is chronic and has been persisting for several weeks.
20. Question: A basketball player presents with sharp pain on the lateral aspect of their ankle following
a recent game. Upon assessment, you suspect either a lateral ankle sprain or a peroneal tendon injury. To
differentiate between the two, you perform the anterior drawer test and note that the talar tilt angle is 10
degrees. What is the most likely injury based on this information?
Solution: The anterior drawer test is used to assess the integrity of the anterior talofibular ligament
(ATFL) in cases of an ankle sprain. If the test is positive (indicating excessive anterior translation of the
talus on the tibia), it is suggestive of a ligamentous injury, such as a lateral ankle sprain. On the other
hand, the talar tilt test is used to assess instability related to the calcaneofibular ligament and the anterior
talofibular ligament. Typically, a talar tilt angle greater than 10 degrees is considered indicative of lateral
ankle instability, often seen in cases of lateral ankle sprains.
Therefore, based on the information provided and the talar tilt angle of 10 degrees, the most likely injury
is a lateral ankle sprain.
21. Question: A soccer player presents with sharp pain in the knee, especially when cutting and pivot-
ing. During the physical exam, the athletic trainer notes tenderness on the medial joint line and a positive
McMurray test. What is the most likely differential diagnosis in this case?
Solution: The symptoms described - sharp pain on the medial joint line, exacerbated with cutting and
a positive McMurray test - are indicative of a meniscal injury. Meniscal tears are common in sports that
involve cutting and pivoting movements like soccer. Therefore, the most likely differential diagnosis in this
case is a meniscal injury.
22. Question: What is the most common grade of ankle sprain in athletes based on lateral ligament
injuries assessment?
Solution: Grade 2 ankle sprain is the most common grade among athletes when assessing lateral liga-
ment injuries. This grade is characterized by partial tearing of the ligament, leading to moderate swelling,
bruising, and instability of the joint. Grade 2 ankle sprains usually require a longer recovery time compared
to Grade 1 sprains but have a better prognosis compared to Grade 3 sprains where the ligament is completely
torn.
23. Question: A basketball player presents with acute pain in the ankle after landing awkwardly from
a jump. On examination, there is tenderness and swelling around the lateral malleolus. The player has
difficulty bearing weight on the affected side. What is the most likely injury based on this presentation?
Solution: The presentation described is consistent with a lateral ankle sprain, which is a common sports-
related injury. The tenderness and swelling around the lateral malleolus, along with difficulty bearing
weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized
under the SCAT5 (Sport Concussion Assessment Tool 5) should be present at minimum to indicate a likely
concussion?
Solution: The SCAT5 consists of 22 symptoms, and according to the SCAT5 guidelines, if an athlete
presents with at least one of the 10 signs of this tool and at least one of the 22 symptoms, it may indicate a
likely concussion. Therefore, a minimum of two symptoms should be present to suggest a likely concussion.
25. Question: During a knee assessment, a sports medicine physician performs the anterior drawer test
to assess for anterior cruciate ligament (ACL) injury. The displacement of the tibia in millimeters from its
starting position to its furthest point is measured. If the physician notes a displacement of 8mm during the
anterior drawer test, how would you interpret this finding?
Solution: The anterior drawer test assesses the integrity of the ACL. A displacement of more than 6mm
in the anterior drawer test is indicative of a positive test for an ACL injury. In this case, with a displacement
of 8mm during the test, it suggests a positive finding for an ACL injury, indicating possible ligamentous
laxity and instability in the knee joint. Further imaging studies, such as MRI, might be warranted for a more
detailed evaluation and confirmation of the ACL injury.
5. Question: A basketball player presents with pain in the anterior knee that worsens with running,
jumping, and cutting movements. Upon assessment, the athletic trainer notes tenderness at the inferior
pole of the patella, along with pain during resisted knee extension. The player reports that the pain started
gradually and has been persistent for the past 6 weeks. Based on these findings, what is the most likely
diagnosis?
Solution: The description provided aligns with the signs and symptoms of patellar tendinopathy, com-
monly known as jumper’s knee. This condition is characterized by pain and tenderness at the inferior pole
of the patella, especially with activities that involve repetitive jumping, running, or cutting movements. The
gradual onset and persistence of symptoms over 6 weeks further support this diagnosis.
Numerical Answer: Patellar tendinopathy
6. Question: In the assessment of a concussion in an athletic injury, how many key symptoms must be
present to diagnose a concussion according to the Sport Concussion Assessment Tool (SCAT-5)?
Solution: According to the Sport Concussion Assessment Tool (SCAT-5), the diagnosis of a concussion
is based on the presence of at least 1 of 22 key symptoms. So, the numerical answer is 1 symptom.
7. Question: During a concussion assessment, which numerical value on the Glasgow Coma Scale
would indicate a severe brain injury?
Solution: The Glasgow Coma Scale (GCS) is used to assess the level of consciousness in a patient with
an acute brain injury, such as a concussion. The scale ranges from 3 to 15, with lower scores indicating
more severe brain injury. A GCS score of 8 or below is considered indicative of a severe brain injury. This
level of severity requires immediate medical attention and intervention.
8. Question: During a standardized sideline assessment for a suspected concussion in an athlete, how
many total questions are typically included in the Standardized Assessment of Concussion (SAC) test?
Solution: The Standardized Assessment of Concussion (SAC) test includes the following components:
orientation questions (5 questions), immediate memory (5 words to remember), concentration (serial sub-
traction tasks), and delayed recall (recalling the 5 words mentioned earlier). Therefore, the total number of
questions in the SAC test is 5 (orientation) + 5 (immediate memory) + 3 (concentration tasks) = 13 questions.
Answer: 13
9. Question: In a patient with a suspected ACL injury, an MRI scan reveals a tear of 1.5 cm in length. If
the total length of the ACL is considered to be 3.5 cm, what percentage of the ACL is affected by the tear?
Solution: To calculate the percentage of the ACL affected by the tear, we will use the formula: Percent-
age affected = (Length of tear / Total length of ACL) * 100
Given: Length of tear = 1.5 cm Total length of ACL = 3.5 cm
Substitute the given values into the formula: Percentage affected = (1.5 cm / 3.5 cm) * 100 Percentage
affected = (0.4286) * 100 Percentage affected 42.86
Therefore, the tear affects approximately 42.86
10. Question: A soccer player presents with pain in their knee after a match. Upon assessment, you
notice swelling, tenderness, and a history of gradual onset of pain over the past 4 weeks. Based on the
presentation, is this sports injury most likely acute or chronic?
Solution: - Acute injuries are typically sudden onset injuries due to an immediate trauma to the body.
Chronic injuries, on the other hand, develop over time due to repetitive stress or overuse.
- In this case, the soccer player’s history of gradual onset of pain over 4 weeks indicates a chronic injury.
Therefore, the sports injury in this scenario is most likely chronic.
11. Question:
During an assessment of an athlete’s ankle injury, the sports medicine professional conducts a Thompson
test to evaluate the integrity of the Achilles tendon. If the athlete’s ankle plantarflexes by 0 degrees compared
to the unaffected side during the test, what percentage of probability does this indicate of a complete Achilles
tendon rupture?
Solution:
A Thompson test is used to assess the integrity of the Achilles tendon, specifically to check for a com-
plete rupture. In a positive Thompson test (0 degrees of ankle plantarflexion), where there is no movement of
the foot in response to calf squeezing, it indicates a high probability of a complete Achilles tendon rupture.
Research indicates that a positive Thompson test has a high sensitivity and specificity for a complete
Achilles tendon rupture, with a likelihood ratio of around 30. This means that a positive test significantly
increases the probability of a complete tear.
Therefore, if the athlete’s ankle plantarflexes by 0 degrees during the Thompson test, it indicates almost
a 100
12. Question: A soccer player presents with pain in their knee that started gradually after increasing
their training intensity over the past few weeks. Upon assessment, the player reports tenderness along the
patellar tendon insertion and pain with running and jumping. Based on the presentation and assessment
findings, what type of sports injury is most likely occurring: acute or chronic? Provide your answer as a
numerical value: 1. Acute 2. Chronic
Solution: Chronic sports injuries develop over time due to repetitive overuse or stress on the body. The
gradual onset of pain after increasing training intensity and tenderness at the patellar tendon insertion point
in this scenario suggest a chronic injury related to overuse. Therefore, the most likely type of sports injury
occurring in this case is: 2. Chronic
13. Question: A basketball player presents with ankle pain after landing awkwardly during a game. The
pain developed suddenly and is localized to the lateral aspect of the ankle. The player reports a popping
sound at the time of injury. Based on this description, on a scale of 1 to 10, how likely is this injury to be
acute rather than chronic?
Solution: In this scenario, an acute injury is more probable due to the sudden onset of pain, localized
pain on the lateral aspect of the ankle (typical for an ankle sprain), and the player reporting a popping sound
which is often associated with ligamentous injury during an acute trauma. Acute injuries typically present
with immediate pain, swelling, and instability. Chronic injuries, on the other hand, develop over time due to
repetitive stress or overuse.
On a scale of 1 to 10, with 1 being very unlikely and 10 being highly likely, the likelihood of this injury
being acute rather than chronic would be around 9.
14. Question: A basketball player presents with symptoms of shoulder pain and limited range of motion.
During assessment, you perform the O’Brien’s Test for labral tears. If the player experiences pain at 90
degrees of shoulder flexion and internal rotation but no pain at 30 degrees of shoulder flexion and internal
rotation, what is the likelihood ratio for a labral tear based on this test result?
Solution: The likelihood ratio for a labral tear can be calculated using the following formula:
Likelihood Ratio =Sensitivity
1−Specificity
First, let’s determine the sensitivity and specificity of the O’Brien’s Test. Sensitivity is the ability of a test to
correctly identify those with the condition, and specificity is the ability of the test to correctly identify those
without the condition.
For the O’Brien’s Test: - Sensitivity: 95- Specificity: 80
Now we can plug in these values into the formula:
Likelihood Ratio =0.95
1−0.80 =0.95
0.20 = 4.75
Therefore, the likelihood ratio for a labral tear based on the O’Brien’s Test result in this case is 4.75.
15. Question: A basketball player presents with pain in the front of their knee and reports that the
symptoms started gradually after increasing their training intensity. On physical examination, they exhibit
tenderness over the inferior pole of the patella and pain with resisted knee extension. What is the most likely
diagnosis for this athlete?
Solution: The symptoms described are characteristic of patellar tendonitis, which is an overuse injury
commonly seen in athletes engaging in sports with repetitive jumping and running. The gradual onset
of symptoms, tenderness over the inferior pole of the patella, and pain with resisted knee extension are
all indicative of patellar tendonitis. To manage this condition, it is important to address the contributing
factors such as overtraining, poor biomechanics, or muscle imbalances through rest, activity modification,
stretching, strengthening exercises, and possibly physical therapy.
The numerical answer: Patellar tendonitis
16. Question: In the assessment of concussions in sports, what is the typical range of scores on the Sport
Concussion Assessment Tool (SCAT) that may indicate a potential concussion?
Solution: The Sport Concussion Assessment Tool (SCAT) is a standardized tool used to assess athletes
for concussions. One component of the SCAT is the Standardized Assessment of Concussion (SAC) portion,
where athletes are evaluated based on their cognitive function through a series of tasks. A typical range of
scores on the SAC portion of the SCAT that may indicate a potential concussion is between 25 to 30 points.
Scores lower than 25 are often considered indicative of a concussion, although it’s essential to evaluate other
factors in conjunction with the SAC score for an accurate diagnosis.
17. Question: In assessing a football player with a suspected grade 2 hamstring strain, how many weeks
of recovery time would typically be recommended?
Solution: A grade 2 hamstring strain involves a significant tear within the muscle resulting in moderate to
severe pain and loss of function. The typical recovery time for a grade 2 hamstring strain in a football player
ranges from 4 to 8 weeks, depending on the extent of the injury and individual healing factors. Therefore,
the recommended recovery time for a grade 2 hamstring strain is approximately 6 weeks.
Answer: 6 weeks
18. Question: An athlete presents with a suspected ankle sprain after a basketball game. A radiograph
of the ankle reveals a lateral malleolus avulsion fracture measuring 5mm in displacement. According to the
Ottawa ankle rules, what is the maximum acceptable displacement for a lateral malleolus avulsion fracture
without requiring further imaging like a CT scan?
Solution: According to the Ottawa ankle rules, for avulsion fractures of the lateral malleolus on ankle
radiographs, the maximum acceptable displacement allowed without needing further imaging is 2mm. In
this case, the 5mm displacement exceeds the threshold, indicating the need for further imaging like a CT
scan.
19. Question: A basketball player experiences an injury to his ankle during a game. The player reports
that the pain started gradually over the past few weeks and has been persistent during games. Based on this
history, is the ankle injury more likely to be considered acute or chronic? Provide your answer in weeks.
Solution: Chronic injuries typically develop over a longer period, often weeks to months, and are char-
acterized by persistent or recurring pain or discomfort. In contrast, acute injuries occur suddenly and are
usually associated with a specific incident.
In this scenario, since the basketball player reports that the pain started gradually over the past few
weeks and has been persistent during games, the ankle injury is more likely to be considered chronic. The
injury has been ongoing for multiple weeks, indicating a longer development time associated with chronic
injuries. Therefore, the ankle injury is chronic and has been persisting for several weeks.
20. Question: A basketball player presents with sharp pain on the lateral aspect of their ankle following
a recent game. Upon assessment, you suspect either a lateral ankle sprain or a peroneal tendon injury. To
differentiate between the two, you perform the anterior drawer test and note that the talar tilt angle is 10
degrees. What is the most likely injury based on this information?
Solution: The anterior drawer test is used to assess the integrity of the anterior talofibular ligament
(ATFL) in cases of an ankle sprain. If the test is positive (indicating excessive anterior translation of the
talus on the tibia), it is suggestive of a ligamentous injury, such as a lateral ankle sprain. On the other
hand, the talar tilt test is used to assess instability related to the calcaneofibular ligament and the anterior
talofibular ligament. Typically, a talar tilt angle greater than 10 degrees is considered indicative of lateral
ankle instability, often seen in cases of lateral ankle sprains.
Therefore, based on the information provided and the talar tilt angle of 10 degrees, the most likely injury
is a lateral ankle sprain.
21. Question: A soccer player presents with sharp pain in the knee, especially when cutting and pivot-
ing. During the physical exam, the athletic trainer notes tenderness on the medial joint line and a positive
McMurray test. What is the most likely differential diagnosis in this case?
Solution: The symptoms described - sharp pain on the medial joint line, exacerbated with cutting and
a positive McMurray test - are indicative of a meniscal injury. Meniscal tears are common in sports that
involve cutting and pivoting movements like soccer. Therefore, the most likely differential diagnosis in this
case is a meniscal injury.
22. Question: What is the most common grade of ankle sprain in athletes based on lateral ligament
injuries assessment?

ment injuries. This grade is characterized by partial tearing of the ligament, leading to moderate swelling,
bruising, and instability of the joint. Grade 2 ankle sprains usually require a longer recovery time compared
to Grade 1 sprains but have a better prognosis compared to Grade 3 sprains where the ligament is completely
torn.
23. Question: A basketball player presents with acute pain in the ankle after landing awkwardly from
a jump. On examination, there is tenderness and swelling around the lateral malleolus. The player has
difficulty bearing weight on the affected side. What is the most likely injury based on this presentation?
Solution: The presentation described is consistent with a lateral ankle sprain, which is a common sports-
related injury. The tenderness and swelling around the lateral malleolus, along with difficulty bearing
weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized
under the SCAT5 (Sport Concussion Assessment Tool 5) should be present at minimum to indicate a likely
concussion?
Solution: The SCAT5 consists of 22 symptoms, and according to the SCAT5 guidelines, if an athlete
presents with at least one of the 10 signs of this tool and at least one of the 22 symptoms, it may indicate a
likely concussion. Therefore, a minimum of two symptoms should be present to suggest a likely concussion.
25. Question: During a knee assessment, a sports medicine physician performs the anterior drawer test
to assess for anterior cruciate ligament (ACL) injury. The displacement of the tibia in millimeters from its
starting position to its furthest point is measured. If the physician notes a displacement of 8mm during the
anterior drawer test, how would you interpret this finding?
Solution: The anterior drawer test assesses the integrity of the ACL. A displacement of more than 6mm
in the anterior drawer test is indicative of a positive test for an ACL injury. In this case, with a displacement
of 8mm during the test, it suggests a positive finding for an ACL injury, indicating possible ligamentous
laxity and instability in the knee joint. Further imaging studies, such as MRI, might be warranted for a more
detailed evaluation and confirmation of the ACL injury.

weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized
under the SCAT5 (Sport Concussion Assessment Tool 5) should be present at minimum to indicate a likely
concussion?
Solution: The SCAT5 consists of 22 symptoms, and according to the SCAT5 guidelines, if an athlete
presents with at least one of the 10 signs of this tool and at least one of the 22 symptoms, it may indicate a
likely concussion. Therefore, a minimum of two symptoms should be present to suggest a likely concussion.
25. Question: During a knee assessment, a sports medicine physician performs the anterior drawer test
to assess for anterior cruciate ligament (ACL) injury. The displacement of the tibia in millimeters from its
starting position to its furthest point is measured. If the physician notes a displacement of 8mm during the
anterior drawer test, how would you interpret this finding?
Solution: The anterior drawer test assesses the integrity of the ACL. A displacement of more than 6mm
in the anterior drawer test is indicative of a positive test for an ACL injury. In this case, with a displacement
of 8mm during the test, it suggests a positive finding for an ACL injury, indicating possible ligamentous
laxity and instability in the knee joint. Further imaging studies, such as MRI, might be warranted for a more
detailed evaluation and confirmation of the ACL injury.
5. Question: A basketball player presents with pain in the anterior knee that worsens with running,
jumping, and cutting movements. Upon assessment, the athletic trainer notes tenderness at the inferior
pole of the patella, along with pain during resisted knee extension. The player reports that the pain started
gradually and has been persistent for the past 6 weeks. Based on these findings, what is the most likely
diagnosis?
Solution: The description provided aligns with the signs and symptoms of patellar tendinopathy, com-
monly known as jumper’s knee. This condition is characterized by pain and tenderness at the inferior pole
of the patella, especially with activities that involve repetitive jumping, running, or cutting movements. The
gradual onset and persistence of symptoms over 6 weeks further support this diagnosis.
Numerical Answer: Patellar tendinopathy
6. Question: In the assessment of a concussion in an athletic injury, how many key symptoms must be
present to diagnose a concussion according to the Sport Concussion Assessment Tool (SCAT-5)?
Solution: According to the Sport Concussion Assessment Tool (SCAT-5), the diagnosis of a concussion
is based on the presence of at least 1 of 22 key symptoms. So, the numerical answer is 1 symptom.
7. Question: During a concussion assessment, which numerical value on the Glasgow Coma Scale
would indicate a severe brain injury?
Solution: The Glasgow Coma Scale (GCS) is used to assess the level of consciousness in a patient with
an acute brain injury, such as a concussion. The scale ranges from 3 to 15, with lower scores indicating
more severe brain injury. A GCS score of 8 or below is considered indicative of a severe brain injury. This
level of severity requires immediate medical attention and intervention.
8. Question: During a standardized sideline assessment for a suspected concussion in an athlete, how
many total questions are typically included in the Standardized Assessment of Concussion (SAC) test?
Solution: The Standardized Assessment of Concussion (SAC) test includes the following components:
orientation questions (5 questions), immediate memory (5 words to remember), concentration (serial sub-
traction tasks), and delayed recall (recalling the 5 words mentioned earlier). Therefore, the total number of
questions in the SAC test is 5 (orientation) + 5 (immediate memory) + 3 (concentration tasks) = 13 questions.
Answer: 13
9. Question: In a patient with a suspected ACL injury, an MRI scan reveals a tear of 1.5 cm in length. If
the total length of the ACL is considered to be 3.5 cm, what percentage of the ACL is affected by the tear?
Solution: To calculate the percentage of the ACL affected by the tear, we will use the formula: Percent-
age affected = (Length of tear / Total length of ACL) * 100
Given: Length of tear = 1.5 cm Total length of ACL = 3.5 cm
Substitute the given values into the formula: Percentage affected = (1.5 cm / 3.5 cm) * 100 Percentage
affected = (0.4286) * 100 Percentage affected 42.86
Therefore, the tear affects approximately 42.86
10. Question: A soccer player presents with pain in their knee after a match. Upon assessment, you
notice swelling, tenderness, and a history of gradual onset of pain over the past 4 weeks. Based on the
presentation, is this sports injury most likely acute or chronic?
Solution: - Acute injuries are typically sudden onset injuries due to an immediate trauma to the body.
Chronic injuries, on the other hand, develop over time due to repetitive stress or overuse.
- In this case, the soccer player’s history of gradual onset of pain over 4 weeks indicates a chronic injury.
Therefore, the sports injury in this scenario is most likely chronic.
11. Question:
During an assessment of an athlete’s ankle injury, the sports medicine professional conducts a Thompson
test to evaluate the integrity of the Achilles tendon. If the athlete’s ankle plantarflexes by 0 degrees compared
to the unaffected side during the test, what percentage of probability does this indicate of a complete Achilles
tendon rupture?
Solution:
A Thompson test is used to assess the integrity of the Achilles tendon, specifically to check for a com-
plete rupture. In a positive Thompson test (0 degrees of ankle plantarflexion), where there is no movement of
the foot in response to calf squeezing, it indicates a high probability of a complete Achilles tendon rupture.
Research indicates that a positive Thompson test has a high sensitivity and specificity for a complete
Achilles tendon rupture, with a likelihood ratio of around 30. This means that a positive test significantly
increases the probability of a complete tear.
Therefore, if the athlete’s ankle plantarflexes by 0 degrees during the Thompson test, it indicates almost
a 100
12. Question: A soccer player presents with pain in their knee that started gradually after increasing
their training intensity over the past few weeks. Upon assessment, the player reports tenderness along the
patellar tendon insertion and pain with running and jumping. Based on the presentation and assessment
findings, what type of sports injury is most likely occurring: acute or chronic? Provide your answer as a
numerical value: 1. Acute 2. Chronic
Solution: Chronic sports injuries develop over time due to repetitive overuse or stress on the body. The
gradual onset of pain after increasing training intensity and tenderness at the patellar tendon insertion point
in this scenario suggest a chronic injury related to overuse. Therefore, the most likely type of sports injury
occurring in this case is: 2. Chronic
13. Question: A basketball player presents with ankle pain after landing awkwardly during a game. The
pain developed suddenly and is localized to the lateral aspect of the ankle. The player reports a popping
sound at the time of injury. Based on this description, on a scale of 1 to 10, how likely is this injury to be
acute rather than chronic?
Solution: In this scenario, an acute injury is more probable due to the sudden onset of pain, localized
pain on the lateral aspect of the ankle (typical for an ankle sprain), and the player reporting a popping sound
which is often associated with ligamentous injury during an acute trauma. Acute injuries typically present
with immediate pain, swelling, and instability. Chronic injuries, on the other hand, develop over time due to
repetitive stress or overuse.
On a scale of 1 to 10, with 1 being very unlikely and 10 being highly likely, the likelihood of this injury
being acute rather than chronic would be around 9.
14. Question: A basketball player presents with symptoms of shoulder pain and limited range of motion.
During assessment, you perform the O’Brien’s Test for labral tears. If the player experiences pain at 90
degrees of shoulder flexion and internal rotation but no pain at 30 degrees of shoulder flexion and internal
rotation, what is the likelihood ratio for a labral tear based on this test result?
Solution: The likelihood ratio for a labral tear can be calculated using the following formula:
Likelihood Ratio =Sensitivity
1−Specificity
First, let’s determine the sensitivity and specificity of the O’Brien’s Test. Sensitivity is the ability of a test to
correctly identify those with the condition, and specificity is the ability of the test to correctly identify those
without the condition.
For the O’Brien’s Test: - Sensitivity: 95- Specificity: 80
Now we can plug in these values into the formula:
Likelihood Ratio =0.95
1−0.80 =0.95
0.20 = 4.75
Therefore, the likelihood ratio for a labral tear based on the O’Brien’s Test result in this case is 4.75.
15. Question: A basketball player presents with pain in the front of their knee and reports that the
symptoms started gradually after increasing their training intensity. On physical examination, they exhibit
tenderness over the inferior pole of the patella and pain with resisted knee extension. What is the most likely
diagnosis for this athlete?
Solution: The symptoms described are characteristic of patellar tendonitis, which is an overuse injury
commonly seen in athletes engaging in sports with repetitive jumping and running. The gradual onset
of symptoms, tenderness over the inferior pole of the patella, and pain with resisted knee extension are
all indicative of patellar tendonitis. To manage this condition, it is important to address the contributing
factors such as overtraining, poor biomechanics, or muscle imbalances through rest, activity modification,
stretching, strengthening exercises, and possibly physical therapy.
The numerical answer: Patellar tendonitis
16. Question: In the assessment of concussions in sports, what is the typical range of scores on the Sport
Concussion Assessment Tool (SCAT) that may indicate a potential concussion?
Solution: The Sport Concussion Assessment Tool (SCAT) is a standardized tool used to assess athletes
for concussions. One component of the SCAT is the Standardized Assessment of Concussion (SAC) portion,
where athletes are evaluated based on their cognitive function through a series of tasks. A typical range of
scores on the SAC portion of the SCAT that may indicate a potential concussion is between 25 to 30 points.
Scores lower than 25 are often considered indicative of a concussion, although it’s essential to evaluate other
factors in conjunction with the SAC score for an accurate diagnosis.
17. Question: In assessing a football player with a suspected grade 2 hamstring strain, how many weeks
of recovery time would typically be recommended?
Solution: A grade 2 hamstring strain involves a significant tear within the muscle resulting in moderate to
severe pain and loss of function. The typical recovery time for a grade 2 hamstring strain in a football player
ranges from 4 to 8 weeks, depending on the extent of the injury and individual healing factors. Therefore,
the recommended recovery time for a grade 2 hamstring strain is approximately 6 weeks.
Answer: 6 weeks
18. Question: An athlete presents with a suspected ankle sprain after a basketball game. A radiograph
of the ankle reveals a lateral malleolus avulsion fracture measuring 5mm in displacement. According to the
Ottawa ankle rules, what is the maximum acceptable displacement for a lateral malleolus avulsion fracture
without requiring further imaging like a CT scan?
Solution: According to the Ottawa ankle rules, for avulsion fractures of the lateral malleolus on ankle
radiographs, the maximum acceptable displacement allowed without needing further imaging is 2mm. In
this case, the 5mm displacement exceeds the threshold, indicating the need for further imaging like a CT
scan.
19. Question: A basketball player experiences an injury to his ankle during a game. The player reports
that the pain started gradually over the past few weeks and has been persistent during games. Based on this
history, is the ankle injury more likely to be considered acute or chronic? Provide your answer in weeks.
Solution: Chronic injuries typically develop over a longer period, often weeks to months, and are char-
acterized by persistent or recurring pain or discomfort. In contrast, acute injuries occur suddenly and are
usually associated with a specific incident.
In this scenario, since the basketball player reports that the pain started gradually over the past few
weeks and has been persistent during games, the ankle injury is more likely to be considered chronic. The
injury has been ongoing for multiple weeks, indicating a longer development time associated with chronic
injuries. Therefore, the ankle injury is chronic and has been persisting for several weeks.
20. Question: A basketball player presents with sharp pain on the lateral aspect of their ankle following
a recent game. Upon assessment, you suspect either a lateral ankle sprain or a peroneal tendon injury. To
differentiate between the two, you perform the anterior drawer test and note that the talar tilt angle is 10
degrees. What is the most likely injury based on this information?
Solution: The anterior drawer test is used to assess the integrity of the anterior talofibular ligament
(ATFL) in cases of an ankle sprain. If the test is positive (indicating excessive anterior translation of the
talus on the tibia), it is suggestive of a ligamentous injury, such as a lateral ankle sprain. On the other
hand, the talar tilt test is used to assess instability related to the calcaneofibular ligament and the anterior
talofibular ligament. Typically, a talar tilt angle greater than 10 degrees is considered indicative of lateral
ankle instability, often seen in cases of lateral ankle sprains.
Therefore, based on the information provided and the talar tilt angle of 10 degrees, the most likely injury
is a lateral ankle sprain.
21. Question: A soccer player presents with sharp pain in the knee, especially when cutting and pivot-
ing. During the physical exam, the athletic trainer notes tenderness on the medial joint line and a positive
McMurray test. What is the most likely differential diagnosis in this case?
Solution: The symptoms described - sharp pain on the medial joint line, exacerbated with cutting and
a positive McMurray test - are indicative of a meniscal injury. Meniscal tears are common in sports that
involve cutting and pivoting movements like soccer. Therefore, the most likely differential diagnosis in this
case is a meniscal injury.
22. Question: What is the most common grade of ankle sprain in athletes based on lateral ligament
injuries assessment?
Solution: Grade 2 ankle sprain is the most common grade among athletes when assessing lateral liga-
ment injuries. This grade is characterized by partial tearing of the ligament, leading to moderate swelling,
bruising, and instability of the joint. Grade 2 ankle sprains usually require a longer recovery time compared
to Grade 1 sprains but have a better prognosis compared to Grade 3 sprains where the ligament is completely
torn.
23. Question: A basketball player presents with acute pain in the ankle after landing awkwardly from
a jump. On examination, there is tenderness and swelling around the lateral malleolus. The player has
difficulty bearing weight on the affected side. What is the most likely injury based on this presentation?
Solution: The presentation described is consistent with a lateral ankle sprain, which is a common sports-
related injury. The tenderness and swelling around the lateral malleolus, along with difficulty bearing
weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized
under the SCAT5 (Sport Concussion Assessment Tool 5) should be present at minimum to indicate a likely
concussion?
Solution: The SCAT5 consists of 22 symptoms, and according to the SCAT5 guidelines, if an athlete
presents with at least one of the 10 signs of this tool and at least one of the 22 symptoms, it may indicate a
likely concussion. Therefore, a minimum of two symptoms should be present to suggest a likely concussion.
25. Question: During a knee assessment, a sports medicine physician performs the anterior drawer test
to assess for anterior cruciate ligament (ACL) injury. The displacement of the tibia in millimeters from its
starting position to its furthest point is measured. If the physician notes a displacement of 8mm during the
anterior drawer test, how would you interpret this finding?
Solution: The anterior drawer test assesses the integrity of the ACL. A displacement of more than 6mm
in the anterior drawer test is indicative of a positive test for an ACL injury. In this case, with a displacement
of 8mm during the test, it suggests a positive finding for an ACL injury, indicating possible ligamentous
laxity and instability in the knee joint. Further imaging studies, such as MRI, might be warranted for a more
detailed evaluation and confirmation of the ACL injury.

traction tasks), and delayed recall (recalling the 5 words mentioned earlier). Therefore, the total number of
questions in the SAC test is 5 (orientation) + 5 (immediate memory) + 3 (concentration tasks) = 13 questions.
Answer: 13
9. Question: In a patient with a suspected ACL injury, an MRI scan reveals a tear of 1.5 cm in length. If
the total length of the ACL is considered to be 3.5 cm, what percentage of the ACL is affected by the tear?
Solution: To calculate the percentage of the ACL affected by the tear, we will use the formula: Percent-
age affected = (Length of tear / Total length of ACL) * 100
Given: Length of tear = 1.5 cm Total length of ACL = 3.5 cm
Substitute the given values into the formula: Percentage affected = (1.5 cm / 3.5 cm) * 100 Percentage
affected = (0.4286) * 100 Percentage affected 42.86
Therefore, the tear affects approximately 42.86
10. Question: A soccer player presents with pain in their knee after a match. Upon assessment, you

23. Question: A basketball player presents with acute pain in the ankle after landing awkwardly from
a jump. On examination, there is tenderness and swelling around the lateral malleolus. The player has
difficulty bearing weight on the affected side. What is the most likely injury based on this presentation?
Solution: The presentation described is consistent with a lateral ankle sprain, which is a common sports-
related injury. The tenderness and swelling around the lateral malleolus, along with difficulty bearing
weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized
under the SCAT5 (Sport Concussion Assessment Tool 5) should be present at minimum to indicate a likely

monly known as jumper’s knee. This condition is characterized by pain and tenderness at the inferior pole
of the patella, especially with activities that involve repetitive jumping, running, or cutting movements. The
gradual onset and persistence of symptoms over 6 weeks further support this diagnosis.
Numerical Answer: Patellar tendinopathy
6. Question: In the assessment of a concussion in an athletic injury, how many key symptoms must be
present to diagnose a concussion according to the Sport Concussion Assessment Tool (SCAT-5)?
Solution: According to the Sport Concussion Assessment Tool (SCAT-5), the diagnosis of a concussion
is based on the presence of at least 1 of 22 key symptoms. So, the numerical answer is 1 symptom.
7. Question: During a concussion assessment, which numerical value on the Glasgow Coma Scale
would indicate a severe brain injury?
Solution: The Glasgow Coma Scale (GCS) is used to assess the level of consciousness in a patient with
an acute brain injury, such as a concussion. The scale ranges from 3 to 15, with lower scores indicating
more severe brain injury. A GCS score of 8 or below is considered indicative of a severe brain injury. This
level of severity requires immediate medical attention and intervention.
8. Question: During a standardized sideline assessment for a suspected concussion in an athlete, how
many total questions are typically included in the Standardized Assessment of Concussion (SAC) test?
Solution: The Standardized Assessment of Concussion (SAC) test includes the following components:
orientation questions (5 questions), immediate memory (5 words to remember), concentration (serial sub-
traction tasks), and delayed recall (recalling the 5 words mentioned earlier). Therefore, the total number of
questions in the SAC test is 5 (orientation) + 5 (immediate memory) + 3 (concentration tasks) = 13 questions.
Answer: 13
9. Question: In a patient with a suspected ACL injury, an MRI scan reveals a tear of 1.5 cm in length. If
the total length of the ACL is considered to be 3.5 cm, what percentage of the ACL is affected by the tear?
Solution: To calculate the percentage of the ACL affected by the tear, we will use the formula: Percent-
age affected = (Length of tear / Total length of ACL) * 100
Given: Length of tear = 1.5 cm Total length of ACL = 3.5 cm
Substitute the given values into the formula: Percentage affected = (1.5 cm / 3.5 cm) * 100 Percentage
affected = (0.4286) * 100 Percentage affected 42.86
Therefore, the tear affects approximately 42.86
10. Question: A soccer player presents with pain in their knee after a match. Upon assessment, you
notice swelling, tenderness, and a history of gradual onset of pain over the past 4 weeks. Based on the
presentation, is this sports injury most likely acute or chronic?
Solution: - Acute injuries are typically sudden onset injuries due to an immediate trauma to the body.
Chronic injuries, on the other hand, develop over time due to repetitive stress or overuse.
- In this case, the soccer player’s history of gradual onset of pain over 4 weeks indicates a chronic injury.
Therefore, the sports injury in this scenario is most likely chronic.
11. Question:
During an assessment of an athlete’s ankle injury, the sports medicine professional conducts a Thompson
test to evaluate the integrity of the Achilles tendon. If the athlete’s ankle plantarflexes by 0 degrees compared
to the unaffected side during the test, what percentage of probability does this indicate of a complete Achilles
tendon rupture?
Solution:
A Thompson test is used to assess the integrity of the Achilles tendon, specifically to check for a com-
plete rupture. In a positive Thompson test (0 degrees of ankle plantarflexion), where there is no movement of
the foot in response to calf squeezing, it indicates a high probability of a complete Achilles tendon rupture.
Research indicates that a positive Thompson test has a high sensitivity and specificity for a complete
Achilles tendon rupture, with a likelihood ratio of around 30. This means that a positive test significantly
increases the probability of a complete tear.
Therefore, if the athlete’s ankle plantarflexes by 0 degrees during the Thompson test, it indicates almost
a 100
12. Question: A soccer player presents with pain in their knee that started gradually after increasing
their training intensity over the past few weeks. Upon assessment, the player reports tenderness along the
patellar tendon insertion and pain with running and jumping. Based on the presentation and assessment
findings, what type of sports injury is most likely occurring: acute or chronic? Provide your answer as a
numerical value: 1. Acute 2. Chronic
Solution: Chronic sports injuries develop over time due to repetitive overuse or stress on the body. The
gradual onset of pain after increasing training intensity and tenderness at the patellar tendon insertion point
in this scenario suggest a chronic injury related to overuse. Therefore, the most likely type of sports injury
occurring in this case is: 2. Chronic
13. Question: A basketball player presents with ankle pain after landing awkwardly during a game. The
pain developed suddenly and is localized to the lateral aspect of the ankle. The player reports a popping
sound at the time of injury. Based on this description, on a scale of 1 to 10, how likely is this injury to be
acute rather than chronic?
Solution: In this scenario, an acute injury is more probable due to the sudden onset of pain, localized
pain on the lateral aspect of the ankle (typical for an ankle sprain), and the player reporting a popping sound
which is often associated with ligamentous injury during an acute trauma. Acute injuries typically present
with immediate pain, swelling, and instability. Chronic injuries, on the other hand, develop over time due to
repetitive stress or overuse.
On a scale of 1 to 10, with 1 being very unlikely and 10 being highly likely, the likelihood of this injury
being acute rather than chronic would be around 9.
14. Question: A basketball player presents with symptoms of shoulder pain and limited range of motion.
During assessment, you perform the O’Brien’s Test for labral tears. If the player experiences pain at 90
degrees of shoulder flexion and internal rotation but no pain at 30 degrees of shoulder flexion and internal
rotation, what is the likelihood ratio for a labral tear based on this test result?
Solution: The likelihood ratio for a labral tear can be calculated using the following formula:
Likelihood Ratio =Sensitivity
1−Specificity
First, let’s determine the sensitivity and specificity of the O’Brien’s Test. Sensitivity is the ability of a test to
correctly identify those with the condition, and specificity is the ability of the test to correctly identify those
without the condition.
For the O’Brien’s Test: - Sensitivity: 95- Specificity: 80
Now we can plug in these values into the formula:
Likelihood Ratio =0.95
1−0.80 =0.95
0.20 = 4.75
Therefore, the likelihood ratio for a labral tear based on the O’Brien’s Test result in this case is 4.75.
15. Question: A basketball player presents with pain in the front of their knee and reports that the
symptoms started gradually after increasing their training intensity. On physical examination, they exhibit
tenderness over the inferior pole of the patella and pain with resisted knee extension. What is the most likely
diagnosis for this athlete?
Solution: The symptoms described are characteristic of patellar tendonitis, which is an overuse injury
commonly seen in athletes engaging in sports with repetitive jumping and running. The gradual onset
of symptoms, tenderness over the inferior pole of the patella, and pain with resisted knee extension are
all indicative of patellar tendonitis. To manage this condition, it is important to address the contributing
factors such as overtraining, poor biomechanics, or muscle imbalances through rest, activity modification,
stretching, strengthening exercises, and possibly physical therapy.
The numerical answer: Patellar tendonitis
16. Question: In the assessment of concussions in sports, what is the typical range of scores on the Sport
Concussion Assessment Tool (SCAT) that may indicate a potential concussion?
Solution: The Sport Concussion Assessment Tool (SCAT) is a standardized tool used to assess athletes
for concussions. One component of the SCAT is the Standardized Assessment of Concussion (SAC) portion,
where athletes are evaluated based on their cognitive function through a series of tasks. A typical range of
scores on the SAC portion of the SCAT that may indicate a potential concussion is between 25 to 30 points.
Scores lower than 25 are often considered indicative of a concussion, although it’s essential to evaluate other
factors in conjunction with the SAC score for an accurate diagnosis.
17. Question: In assessing a football player with a suspected grade 2 hamstring strain, how many weeks
of recovery time would typically be recommended?
Solution: A grade 2 hamstring strain involves a significant tear within the muscle resulting in moderate to
severe pain and loss of function. The typical recovery time for a grade 2 hamstring strain in a football player
ranges from 4 to 8 weeks, depending on the extent of the injury and individual healing factors. Therefore,
the recommended recovery time for a grade 2 hamstring strain is approximately 6 weeks.
Answer: 6 weeks
18. Question: An athlete presents with a suspected ankle sprain after a basketball game. A radiograph
of the ankle reveals a lateral malleolus avulsion fracture measuring 5mm in displacement. According to the
Ottawa ankle rules, what is the maximum acceptable displacement for a lateral malleolus avulsion fracture
without requiring further imaging like a CT scan?
Solution: According to the Ottawa ankle rules, for avulsion fractures of the lateral malleolus on ankle
radiographs, the maximum acceptable displacement allowed without needing further imaging is 2mm. In
this case, the 5mm displacement exceeds the threshold, indicating the need for further imaging like a CT
scan.
19. Question: A basketball player experiences an injury to his ankle during a game. The player reports
that the pain started gradually over the past few weeks and has been persistent during games. Based on this
history, is the ankle injury more likely to be considered acute or chronic? Provide your answer in weeks.
Solution: Chronic injuries typically develop over a longer period, often weeks to months, and are char-
acterized by persistent or recurring pain or discomfort. In contrast, acute injuries occur suddenly and are
usually associated with a specific incident.
In this scenario, since the basketball player reports that the pain started gradually over the past few
weeks and has been persistent during games, the ankle injury is more likely to be considered chronic. The
injury has been ongoing for multiple weeks, indicating a longer development time associated with chronic
injuries. Therefore, the ankle injury is chronic and has been persisting for several weeks.
20. Question: A basketball player presents with sharp pain on the lateral aspect of their ankle following
a recent game. Upon assessment, you suspect either a lateral ankle sprain or a peroneal tendon injury. To
differentiate between the two, you perform the anterior drawer test and note that the talar tilt angle is 10
degrees. What is the most likely injury based on this information?
Solution: The anterior drawer test is used to assess the integrity of the anterior talofibular ligament
(ATFL) in cases of an ankle sprain. If the test is positive (indicating excessive anterior translation of the
talus on the tibia), it is suggestive of a ligamentous injury, such as a lateral ankle sprain. On the other
hand, the talar tilt test is used to assess instability related to the calcaneofibular ligament and the anterior
talofibular ligament. Typically, a talar tilt angle greater than 10 degrees is considered indicative of lateral
ankle instability, often seen in cases of lateral ankle sprains.
Therefore, based on the information provided and the talar tilt angle of 10 degrees, the most likely injury
is a lateral ankle sprain.
21. Question: A soccer player presents with sharp pain in the knee, especially when cutting and pivot-
ing. During the physical exam, the athletic trainer notes tenderness on the medial joint line and a positive
McMurray test. What is the most likely differential diagnosis in this case?
Solution: The symptoms described - sharp pain on the medial joint line, exacerbated with cutting and
a positive McMurray test - are indicative of a meniscal injury. Meniscal tears are common in sports that
involve cutting and pivoting movements like soccer. Therefore, the most likely differential diagnosis in this
case is a meniscal injury.
22. Question: What is the most common grade of ankle sprain in athletes based on lateral ligament
injuries assessment?
Solution: Grade 2 ankle sprain is the most common grade among athletes when assessing lateral liga-
ment injuries. This grade is characterized by partial tearing of the ligament, leading to moderate swelling,
bruising, and instability of the joint. Grade 2 ankle sprains usually require a longer recovery time compared
to Grade 1 sprains but have a better prognosis compared to Grade 3 sprains where the ligament is completely
torn.
23. Question: A basketball player presents with acute pain in the ankle after landing awkwardly from
a jump. On examination, there is tenderness and swelling around the lateral malleolus. The player has
difficulty bearing weight on the affected side. What is the most likely injury based on this presentation?
Solution: The presentation described is consistent with a lateral ankle sprain, which is a common sports-
related injury. The tenderness and swelling around the lateral malleolus, along with difficulty bearing
weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized
under the SCAT5 (Sport Concussion Assessment Tool 5) should be present at minimum to indicate a likely
concussion?
Solution: The SCAT5 consists of 22 symptoms, and according to the SCAT5 guidelines, if an athlete
presents with at least one of the 10 signs of this tool and at least one of the 22 symptoms, it may indicate a
likely concussion. Therefore, a minimum of two symptoms should be present to suggest a likely concussion.
25. Question: During a knee assessment, a sports medicine physician performs the anterior drawer test
to assess for anterior cruciate ligament (ACL) injury. The displacement of the tibia in millimeters from its
starting position to its furthest point is measured. If the physician notes a displacement of 8mm during the
anterior drawer test, how would you interpret this finding?
Solution: The anterior drawer test assesses the integrity of the ACL. A displacement of more than 6mm
in the anterior drawer test is indicative of a positive test for an ACL injury. In this case, with a displacement
of 8mm during the test, it suggests a positive finding for an ACL injury, indicating possible ligamentous
laxity and instability in the knee joint. Further imaging studies, such as MRI, might be warranted for a more
detailed evaluation and confirmation of the ACL injury.
5. Question: A basketball player presents with pain in the anterior knee that worsens with running,
jumping, and cutting movements. Upon assessment, the athletic trainer notes tenderness at the inferior
pole of the patella, along with pain during resisted knee extension. The player reports that the pain started
gradually and has been persistent for the past 6 weeks. Based on these findings, what is the most likely
diagnosis?
Solution: The description provided aligns with the signs and symptoms of patellar tendinopathy, com-
monly known as jumper’s knee. This condition is characterized by pain and tenderness at the inferior pole
of the patella, especially with activities that involve repetitive jumping, running, or cutting movements. The
gradual onset and persistence of symptoms over 6 weeks further support this diagnosis.
Numerical Answer: Patellar tendinopathy

is based on the presence of at least 1 of 22 key symptoms. So, the numerical answer is 1 symptom.
7. Question: During a concussion assessment, which numerical value on the Glasgow Coma Scale
would indicate a severe brain injury?
Solution: The Glasgow Coma Scale (GCS) is used to assess the level of consciousness in a patient with
an acute brain injury, such as a concussion. The scale ranges from 3 to 15, with lower scores indicating
more severe brain injury. A GCS score of 8 or below is considered indicative of a severe brain injury. This
level of severity requires immediate medical attention and intervention.
8. Question: During a standardized sideline assessment for a suspected concussion in an athlete, how

traction tasks), and delayed recall (recalling the 5 words mentioned earlier). Therefore, the total number of
questions in the SAC test is 5 (orientation) + 5 (immediate memory) + 3 (concentration tasks) = 13 questions.
Answer: 13
9. Question: In a patient with a suspected ACL injury, an MRI scan reveals a tear of 1.5 cm in length. If
the total length of the ACL is considered to be 3.5 cm, what percentage of the ACL is affected by the tear?
Solution: To calculate the percentage of the ACL affected by the tear, we will use the formula: Percent-
age affected = (Length of tear / Total length of ACL) * 100
Given: Length of tear = 1.5 cm Total length of ACL = 3.5 cm
Substitute the given values into the formula: Percentage affected = (1.5 cm / 3.5 cm) * 100 Percentage
affected = (0.4286) * 100 Percentage affected 42.86
Therefore, the tear affects approximately 42.86
10. Question: A soccer player presents with pain in their knee after a match. Upon assessment, you
notice swelling, tenderness, and a history of gradual onset of pain over the past 4 weeks. Based on the

To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized

Substitute the given values into the formula: Percentage affected = (1.5 cm / 3.5 cm) * 100 Percentage
affected = (0.4286) * 100 Percentage affected 42.86
Therefore, the tear affects approximately 42.86
10. Question: A soccer player presents with pain in their knee after a match. Upon assessment, you
notice swelling, tenderness, and a history of gradual onset of pain over the past 4 weeks. Based on the
presentation, is this sports injury most likely acute or chronic?
Solution: - Acute injuries are typically sudden onset injuries due to an immediate trauma to the body.
Chronic injuries, on the other hand, develop over time due to repetitive stress or overuse.
- In this case, the soccer player’s history of gradual onset of pain over 4 weeks indicates a chronic injury.
Therefore, the sports injury in this scenario is most likely chronic.
11. Question:
During an assessment of an athlete’s ankle injury, the sports medicine professional conducts a Thompson
test to evaluate the integrity of the Achilles tendon. If the athlete’s ankle plantarflexes by 0 degrees compared
to the unaffected side during the test, what percentage of probability does this indicate of a complete Achilles
tendon rupture?
Solution:
A Thompson test is used to assess the integrity of the Achilles tendon, specifically to check for a com-
plete rupture. In a positive Thompson test (0 degrees of ankle plantarflexion), where there is no movement of
the foot in response to calf squeezing, it indicates a high probability of a complete Achilles tendon rupture.
Research indicates that a positive Thompson test has a high sensitivity and specificity for a complete
Achilles tendon rupture, with a likelihood ratio of around 30. This means that a positive test significantly
increases the probability of a complete tear.
Therefore, if the athlete’s ankle plantarflexes by 0 degrees during the Thompson test, it indicates almost
a 100
12. Question: A soccer player presents with pain in their knee that started gradually after increasing
their training intensity over the past few weeks. Upon assessment, the player reports tenderness along the
patellar tendon insertion and pain with running and jumping. Based on the presentation and assessment
findings, what type of sports injury is most likely occurring: acute or chronic? Provide your answer as a
numerical value: 1. Acute 2. Chronic
Solution: Chronic sports injuries develop over time due to repetitive overuse or stress on the body. The
gradual onset of pain after increasing training intensity and tenderness at the patellar tendon insertion point
in this scenario suggest a chronic injury related to overuse. Therefore, the most likely type of sports injury
occurring in this case is: 2. Chronic
13. Question: A basketball player presents with ankle pain after landing awkwardly during a game. The
pain developed suddenly and is localized to the lateral aspect of the ankle. The player reports a popping
sound at the time of injury. Based on this description, on a scale of 1 to 10, how likely is this injury to be
acute rather than chronic?
Solution: In this scenario, an acute injury is more probable due to the sudden onset of pain, localized
pain on the lateral aspect of the ankle (typical for an ankle sprain), and the player reporting a popping sound
which is often associated with ligamentous injury during an acute trauma. Acute injuries typically present
with immediate pain, swelling, and instability. Chronic injuries, on the other hand, develop over time due to
repetitive stress or overuse.
On a scale of 1 to 10, with 1 being very unlikely and 10 being highly likely, the likelihood of this injury
being acute rather than chronic would be around 9.
14. Question: A basketball player presents with symptoms of shoulder pain and limited range of motion.
During assessment, you perform the O’Brien’s Test for labral tears. If the player experiences pain at 90
degrees of shoulder flexion and internal rotation but no pain at 30 degrees of shoulder flexion and internal
rotation, what is the likelihood ratio for a labral tear based on this test result?
Solution: The likelihood ratio for a labral tear can be calculated using the following formula:
Likelihood Ratio =Sensitivity
1−Specificity
First, let’s determine the sensitivity and specificity of the O’Brien’s Test. Sensitivity is the ability of a test to
correctly identify those with the condition, and specificity is the ability of the test to correctly identify those
without the condition.
For the O’Brien’s Test: - Sensitivity: 95- Specificity: 80
Now we can plug in these values into the formula:
Likelihood Ratio =0.95
1−0.80 =0.95
0.20 = 4.75
Therefore, the likelihood ratio for a labral tear based on the O’Brien’s Test result in this case is 4.75.
15. Question: A basketball player presents with pain in the front of their knee and reports that the
symptoms started gradually after increasing their training intensity. On physical examination, they exhibit
tenderness over the inferior pole of the patella and pain with resisted knee extension. What is the most likely
diagnosis for this athlete?
Solution: The symptoms described are characteristic of patellar tendonitis, which is an overuse injury
commonly seen in athletes engaging in sports with repetitive jumping and running. The gradual onset
of symptoms, tenderness over the inferior pole of the patella, and pain with resisted knee extension are
all indicative of patellar tendonitis. To manage this condition, it is important to address the contributing
factors such as overtraining, poor biomechanics, or muscle imbalances through rest, activity modification,
stretching, strengthening exercises, and possibly physical therapy.
The numerical answer: Patellar tendonitis
16. Question: In the assessment of concussions in sports, what is the typical range of scores on the Sport
Concussion Assessment Tool (SCAT) that may indicate a potential concussion?
Solution: The Sport Concussion Assessment Tool (SCAT) is a standardized tool used to assess athletes
for concussions. One component of the SCAT is the Standardized Assessment of Concussion (SAC) portion,
where athletes are evaluated based on their cognitive function through a series of tasks. A typical range of
scores on the SAC portion of the SCAT that may indicate a potential concussion is between 25 to 30 points.
Scores lower than 25 are often considered indicative of a concussion, although it’s essential to evaluate other
factors in conjunction with the SAC score for an accurate diagnosis.
17. Question: In assessing a football player with a suspected grade 2 hamstring strain, how many weeks
of recovery time would typically be recommended?
Solution: A grade 2 hamstring strain involves a significant tear within the muscle resulting in moderate to
severe pain and loss of function. The typical recovery time for a grade 2 hamstring strain in a football player
ranges from 4 to 8 weeks, depending on the extent of the injury and individual healing factors. Therefore,
the recommended recovery time for a grade 2 hamstring strain is approximately 6 weeks.
Answer: 6 weeks
18. Question: An athlete presents with a suspected ankle sprain after a basketball game. A radiograph
of the ankle reveals a lateral malleolus avulsion fracture measuring 5mm in displacement. According to the
Ottawa ankle rules, what is the maximum acceptable displacement for a lateral malleolus avulsion fracture
without requiring further imaging like a CT scan?
Solution: According to the Ottawa ankle rules, for avulsion fractures of the lateral malleolus on ankle
radiographs, the maximum acceptable displacement allowed without needing further imaging is 2mm. In
this case, the 5mm displacement exceeds the threshold, indicating the need for further imaging like a CT
scan.
19. Question: A basketball player experiences an injury to his ankle during a game. The player reports
that the pain started gradually over the past few weeks and has been persistent during games. Based on this
history, is the ankle injury more likely to be considered acute or chronic? Provide your answer in weeks.
Solution: Chronic injuries typically develop over a longer period, often weeks to months, and are char-
acterized by persistent or recurring pain or discomfort. In contrast, acute injuries occur suddenly and are
usually associated with a specific incident.
In this scenario, since the basketball player reports that the pain started gradually over the past few
weeks and has been persistent during games, the ankle injury is more likely to be considered chronic. The
injury has been ongoing for multiple weeks, indicating a longer development time associated with chronic
injuries. Therefore, the ankle injury is chronic and has been persisting for several weeks.
20. Question: A basketball player presents with sharp pain on the lateral aspect of their ankle following
a recent game. Upon assessment, you suspect either a lateral ankle sprain or a peroneal tendon injury. To
differentiate between the two, you perform the anterior drawer test and note that the talar tilt angle is 10
degrees. What is the most likely injury based on this information?
Solution: The anterior drawer test is used to assess the integrity of the anterior talofibular ligament
(ATFL) in cases of an ankle sprain. If the test is positive (indicating excessive anterior translation of the
talus on the tibia), it is suggestive of a ligamentous injury, such as a lateral ankle sprain. On the other
hand, the talar tilt test is used to assess instability related to the calcaneofibular ligament and the anterior
talofibular ligament. Typically, a talar tilt angle greater than 10 degrees is considered indicative of lateral
ankle instability, often seen in cases of lateral ankle sprains.
Therefore, based on the information provided and the talar tilt angle of 10 degrees, the most likely injury
is a lateral ankle sprain.
21. Question: A soccer player presents with sharp pain in the knee, especially when cutting and pivot-
ing. During the physical exam, the athletic trainer notes tenderness on the medial joint line and a positive
McMurray test. What is the most likely differential diagnosis in this case?
Solution: The symptoms described - sharp pain on the medial joint line, exacerbated with cutting and
a positive McMurray test - are indicative of a meniscal injury. Meniscal tears are common in sports that
involve cutting and pivoting movements like soccer. Therefore, the most likely differential diagnosis in this
case is a meniscal injury.
22. Question: What is the most common grade of ankle sprain in athletes based on lateral ligament
injuries assessment?
Solution: Grade 2 ankle sprain is the most common grade among athletes when assessing lateral liga-
ment injuries. This grade is characterized by partial tearing of the ligament, leading to moderate swelling,
bruising, and instability of the joint. Grade 2 ankle sprains usually require a longer recovery time compared
to Grade 1 sprains but have a better prognosis compared to Grade 3 sprains where the ligament is completely
torn.
23. Question: A basketball player presents with acute pain in the ankle after landing awkwardly from
a jump. On examination, there is tenderness and swelling around the lateral malleolus. The player has
difficulty bearing weight on the affected side. What is the most likely injury based on this presentation?
Solution: The presentation described is consistent with a lateral ankle sprain, which is a common sports-
related injury. The tenderness and swelling around the lateral malleolus, along with difficulty bearing
weight, are typical signs of this injury.
To diagnose the severity of the sprain, healthcare providers often use the grading system: - Grade 1:
Mild sprain with minimal stretching or tearing of ligaments - Grade 2: Moderate sprain with partial tearing
of ligaments and moderate instability - Grade 3: Severe sprain with complete tearing of ligaments and
significant instability
Given the difficulty bearing weight, this suggests at least a moderate-grade sprain. Healthcare providers
may further assess through physical examination and imaging if necessary to confirm the severity.
Therefore, based on the presentation described, the most likely injury is a Grade 2 lateral ankle sprain.
Final numerical answer: Grade 2
24. Question: In the evaluation of a suspected concussion in an athlete, how many symptoms categorized
under the SCAT5 (Sport Concussion Assessment Tool 5) should be present at minimum to indicate a likely
concussion?
Solution: The SCAT5 consists of 22 symptoms, and according to the SCAT5 guidelines, if an athlete
presents with at least one of the 10 signs of this tool and at least one of the 22 symptoms, it may indicate a
likely concussion. Therefore, a minimum of two symptoms should be present to suggest a likely concussion.
25. Question: During a knee assessment, a sports medicine physician performs the anterior drawer test
to assess for anterior cruciate ligament (ACL) injury. The displacement of the tibia in millimeters from its
starting position to its furthest point is measured. If the physician notes a displacement of 8mm during the
anterior drawer test, how would you interpret this finding?
Solution: The anterior drawer test assesses the integrity of the ACL. A displacement of more than 6mm
in the anterior drawer test is indicative of a positive test for an ACL injury. In this case, with a displacement
of 8mm during the test, it suggests a positive finding for an ACL injury, indicating possible ligamentous
laxity and instability in the knee joint. Further imaging studies, such as MRI, might be warranted for a more
detailed evaluation and confirmation of the ACL injury.
