BACKGROUND: This study aimed to systematically evaluate the therapeutic effects of acupotomy combined with acupuncture and moxibustion on knee osteoarthritis (KOA), which was expected to provide a reference for clinical treatment of KOA using traditional Chinese medicine (TCM). METHODS: The databases PubMed, Embase, Medline, Ovid, and Springer were searched to retrieve randomized controlled trials (RCTs) on KOA treatment by acupotomy combined with acupuncture and moxibustion. The search time was set as from the date the database was established to 31 December 2020. The Cochrane Handbook for Systematic Reviews of Intervention 5.0.2 was used to conduct bias risk assessment on the included literature, and Review Manager 5.3 software was used for meta-analysis. RESULTS: A total of 10 RCTs were included in this study, including 1,073 participants. Meta-analysis results showed that compared with the control group, the clinical treatment efficiency of the experimental group was higher (mean difference (MD) 5.72; 95% confidence interval (CI) 3.39 to 9.64; z = 6.54; p < 0.00001), and the postoperative visual analogue scale (VAS) scores were reduced (MD 1.72; 95% CI -2.41 to -1.03; z = 4.86; p < 0.00001). DISCUSSION: Acupotomy combined with acupuncture and moxibustion treatment for KOA can increase clinical treatment efficiency, and relieve postoperative pain, suggesting that the combination of acupotomy, acupuncture, and moxibustion has better therapeutic effects on KOA and can be promoted clinically.
