Objective To systematically review the efficacy of moxibustion in the treatment of model rabbits with knee osteoarthritis (KOA).Methods CNKI, WanFang Data, VIP, CBM, PubMed, EMbase and The Cochrane Library databases were electronically searched to collect animal experiments on moxibustion in the treatment of model rabbits with KOA from inception to January 31st, 2019. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Meta-analysis was then performed by using RevMan 5.3 software.Results A total of 13 articles involving 226 model rabbits were included. The results of meta-analysis showed that moxibustion could reduce Mankin score (MD=−6.47, 95%CI −7.63 to −5.32, P<0.000 01), positive expression rate of chondrocyte apoptosis (MD=−22.21, 95%CI −23.22 to −21.21, P<0.000 01), level of IL-1β in joint fluid (SMD=−8.40, 95%CI −15.09 to −1.72, P=0.01), NO content in joint fluid (SMD=−11.03, 95%CI −17.87 to −4.19, P=0.002), the level of serum IL-1β (MD=−19.94, 95%CI −23.61 to −16.27, P<0.05), and serum NO content (MD=−22.69, 95%CI −28.77 to −16.61, P<0.05) of model rabbits with KOA.Conclusions Current evidence shows that moxibustion can improve articular cartilage injury, strengthen chondrocyte activity, inhibit the inflammatory response, and inhibit chondrocyte apoptosis of model rabbits with KOA. Due to the limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
