Abstract:
OBJECTIVE: Electroacupuncture has been commonly used in clinical practice for pain after total knee arthroplasty, but its effects and safety remain controversial. The efficacy and safety of electroacupuncture in the treatment of pain after total knee arthroplasty were systematically evaluated. METHODS: PubMed, Embase, Cochrane Library, SinoMed, CNKI, VIP and Wanfang databases were searched to collect randomized controlled trials on electroacupuncture in the treatment of pain after total knee arthroplasty from inception to December 31, 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was performed by RevMan 5.3 software. RESULTS: (1) A total of six studies involving 304 patients were included. (2) The results of meta-analysis showed that compared with control group, the experimental group had significantly lower visual analogue scale scores at 3 days [MD=-0.67, 95%CI(-1.01 to-0.33), P < 0.001], 7 days [MD=-0.60, 95%CI (-0.88 to-0.33), P < 0.001), 14 days [MD=-0.97, 95%CI(-1.74 to-0.21), P < 0.05) and end point of clinical trial (MD=-0.67, 95%CI(-1.04 to-0.30), P < 0.001), respectively, after total knee arthroplasty. There were no significant differences in visual analogue scale scores at 1 day after total knee arthroplasty [MD=-0.12, 95%CI(-0.64, 0.40), P >0.05). (3) The incidence of postoperative vertigo was significantly lower in the trial group than that in the control group [OR=0.28, 95%CI(0.10, 0.78), P < 0.05]. (4) The incidence of postoperative vomiting was not significantly different between the trial and control groups [OR=0.83, 95%CI(0.37, 1.87), P > 0.05]. CONCLUSION: Electroacupuncture has obvious advantages in the treatment of pain after total knee arthroplasty, which can significantly relieve the pain reaction of patients at 3, 7, 14 days and the end point of clinical trial, and can reduce the incidence of postoperative vertigo, but it cannot reduce the incidence of postoperative vomiting and pain at 1 day after total knee arthroplasty. Due to the limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
