BACKGROUND: Wrist-ankle acupuncture (WAA) has been reported in the treatment of acute pain in orthopedic surgery. However, the effects of WAA on acute pain were controversial in the current studies. Therefore, the purpose of this meta-analysis was to critically evaluate the effects of WAA on acute pain in orthopedic surgery. METHODS: Several digital databases were searched from the inception of databases to July 2021, including CNKI, VIP, Wanfang, CBM, Pubmed, Cochrane Central Register of Controlled Trials, Embase, Medline, and Web of Science Core Collection. The risk of bias was evaluated using the Cochrane collaboration criteria. The primary outcome indicators included pain score, pain killer dosage, analgesia satisfaction, and adverse reaction incidence. All analyses were performed with Review Manager 5.4.1. RESULT: A total of 10 studies with 725 patients with orthopedic surgery (intervention group: 361, control group: 364) were included in this meta-analysis. The results demonstrated that the pain score of the intervention group was lower than the control group, and the difference was statistically significant (MD -0.29, 95% CI (-0.37 to -0.21), p < 0.0001). Compared with the control group, the patient in the intervention group used smaller amounts of pain killer (MD -0.16, 95% CI (-0.30 to -0.02), p = 0.02). The satisfaction of patients on pain relief was also higher in the intervention group, and the difference was statistically (OR 0.25, 95% CI (0.15 to 0.41), p < 0.0001). CONCLUSION: WAA has a certain effect on acute pain in orthopedic surgery, and the effect of WAA combined with other therapies is better than that of not using WAA therapy.
