Objectives To systematically review the complications of knee arthroscopic surgeries in China.Methods We searched PubMed, EMbase, CNKI, WanFang Data and VIP databases to collect cross-sectional studies on the complications of knee arthroscopic surgeries in China from inception to March 1st, 2019. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using Stata 12.0 software.Results A total of 36 studies involving 20 740 cases were included. The results of meta-analysis showed the incidence rate of complication in knee arthroscopic surgeries in China was 9.71% (95%CI 8.20% to 11.23%). Subgroup analysis showed that the complication incidence rates in the eastern, central and western regions were 10.04% (95%CI 8.00% to 12.14%), 9.67% (95%CI 6.57% to 12.76%) and 7.47% (95%CI 6.20% to 8.73%). The complication incidence rates in the upper first-class and non-upper first-class hospitals were 9.50% (95%CI 7.83% to 11.17%) and 10.95% (95%CI 6.75% to 15.14%). The top 3 complication types with highest incidence rate included joint effusion[2.16% (95%CI 1.44% to 2.87%)], accidental injury of native structures[1.49% (95%CI 0.96% to 2.03%)] and hemorrhage[1.43% (95%CI 1.01% to 1.84%)]. Other severe complications including neurovascular injury, thrombosis diseases and infection were 0.06% (95%CI 0.02% to 0.11%), 0.33% (95%CI 0.19% to 0.48%) and 0.08% (95%CI 0.03% to 0.13%).Conclusions Current evidence shows that the complication incidence rate of arthroscopic surgeries in China is relatively high and the complication type is complex and varied. Due to the quantity and quality of the included studies, more high-quality studies are required to verify the above conclusions in future.
