• First m

eta-analysis to evaluate the efficiency and safety of TEN S

for pain control in TKA. •

TEN S could significantly reduce the VAS scores and opioid

consum ption at 12 , 24, and 48 h, after TKA.

• Effective pain control: early am

bulation and m aintains m

otor function. The risk of throm

botic events and m edical costs w

ould be decreased under adequate analgesia.

• Reduction of opioid consum

ption decreased side effects such, as (nausea and vom

iting).

Lim itations:

• Sam

ple size w as relatively sm

all. •

Som e im

portant outcom es, such as range of m

otion, w ere not

included or fully described •

The m ethods of blinding w

ere unclear or not described •

Short-term follow

-up (underestim ation of com

plications) •

Publication bias inherent to m eta-analysis studies.

Conclusions: TEN

S could significantly reduce pain and opioid consum ption

after TKA. In addition, there w ere few

er adverse effects in the TEN

S groups. Higher quality RCTs are required for further research.

• Significant differences in the incidence of nausea

(P=.020) and vom

iting (P=.018)

Discussion/Im plications

Lim itations/Conclusions

• Focus: Transcutaneous electrical nerve stim

ulation (TEN S)

after total knee arthroplasty (TKA). •

Problem : N

o m eta-analysis has investigated the effectiveness

and safety of TEN S in the setting of postoperative relief of

pain after TKA. •

Benefits: Increase scientific evidence on effectiveness of TEN S

in pain m anagem

ent after TKA. •

Purpose: Evaluate the efficiency and safety of TEN S for pain

control after TKA.

• Setting /Sam

pling: A system atic search w

as perform ed in

M edline PubM

ed, ScienceDirect and the Cochrane Library. O

nly random ized trials (RCT) w

ere included. •

Study design: M eta-analysis of RCTs

• Search strategy: Key w

ords: ”total knee replacem ent O

R arthroplasty", "transcutaneous electrical nerve stim

ulation“ and pain control.

• Data extraction: Prim

ary outcom es: VAS scores and opioids

consum ption at 12, 24, and 48 h. Secondary outcom

es: Side effects (nauseas and vom

iting) •

Statistical M ethods: The fixed /random

effect m odel w

as used according to the heterogeneity tested by I 2statistic.

Introduction

M ethods/Data Collection/Data Analysis

• Significant differences (P < .05) w

ere found regarding opioid consum

ption at 2 h, 24 h, and 48 h.

O utcom

es/Results/G raphs

• Five RCTs, including 472 patients m

et the inclusion criteria. Study G

roup N =237; Control G

roup N =235

• Significant differences (P < .05) betw

een groups in term

s of VAS at 12, 24, and 48 h after TKA.
