Transcutaneous electrical nerve stimulation is a possible
adjunctive therapy to pharmacological treatment for controlling pain after total
knee arthroplasty. However, the results are controversial.
A systematic review
and meta-analysis was conducted to explore the effect of transcutaneous
electrical nerve stimulation on patients with total knee arthroplasty. METHODS:
PubMed, Embase, Web of Science, EBSCO, and Cochrane Library databases were
searched systematically. Randomized controlled trials assessing the effect of
transcutaneous electrical nerve stimulation on patients with total knee
arthroplasty were included. Two investigators independently searched articles,
extracted data, and assessed the quality of included studies. Primary outcome was
visual analogue scale (VAS) score over a period of 24 h. Meta-analysis was
performed using a random-effect model. RESULTS: Six randomized controlled trials
involving 529 patients were included in the meta-analysis. Overall, compared with
control intervention, transcutaneous electrical nerve stimulation supplementation
intervention was found to significantly reduce VAS scores and total postoperative
morphine dose over a period of 24 h, and to improve active range of knee motion
(standard mean difference (SMD) = 0.37; 95% confidence interval (95% CI) =
0.06-0.68; p = 0.02), but had no effect on VAS scores at 2 weeks (SMD = 0.20; 95%
CI = -0.07 to 0.48; p = 0.15). CONCLUSION: Compared with control intervention,
transcutaneous electrical nerve stimulation supplementation intervention was
found to significantly reduce pain and morphine requirement over a period of 24 h
and to promote functional recovery in patients who have undergone total knee
arthroplasty.
