Objective:To revaluate the systematic review/meta-analysis on efficacy and safety of acupuncture treatment for knee osteoarthritis.Methods:We searched CNKI, VIP, WangFang, CBM, PubMed, Cochrane Library databases, Embase, from inception to December 15, 2020, to retrieve systematic reviews and/or meta analyses on the treatment of knee osteoarthritis with acupuncture and moxibustion. Two researchers independently screened the literature and extracted data, used the AMSTAR2 scale to evaluate the methodological quality, and used the GRADE system to grade the quality of evidence.Results:A total of 11 systematic evaluations were included, including 44 outcomes. Methodological evaluation showed that all 11 literatures were of very low quality. The GRADE system evaluation showed that there were 13 intermediate evidences, 12 low evidences, and 19 very low evidences.Conclusion:The results of the existing systematic reviews show that acupuncture and moxibustion have a certain efficacy in the treatment of knee osteoarthritis, but the methodology and evidence level of the included studies are low, so this conclusion needs to be verified by further high-quality studies.
