Computerized searches of randomized controlled trials were conducted in PubMed, EMbase, Cochrane Library, and Web of Science, with a search time frame until January 2024. Methodological and experimental quality was assessed using the risk of bias assessment tool recommended by the Cochrane Handbook. A meta-analysis was conducted of the pain score (as the primary outcome measure) using Review Manager 5.4 and Stata 17. Thirteen studies involving a total of 731 patients were ultimately included. In the comparison of GNB and non-GNB, the analysis results of analgesic effects at all visits showed [SMD=− 0.51, 95% CI (− 0.89, − 0.14)]. Analysis of analgesic effects at a visit at 1 month showed [SMD=− 0.79, 95% CI (− 1.55, − 0.02)]. Subgroup analysis for the control group showed [SMD=− 4.07,9 5% CI (− 4.10, − 1.84)]. Currently, available evidence suggests that GNB may be an effective analgesic therapy and superior to other regimens in the treatment of lesions of the knee joint.Keywords: knee joint, pain, genicular nerve block, meta-analysis |
