Objective To explore clinical efficacy of autologous bone grafts and bone substitute for the treatment of tibial plateau fractures by Meta analysis.Methods Controlled clinical studies on autogenous bone transplantation and bone substitutes in treating tibial plateau fractures published on PubMed,Web of Science,CNKI,Wanfang and other databases from January 2005 to August 2022 were searched by computer.Literature screening and data extraction were performed according to random-ized controlled trial(RCT),and the quality of RCT were evaluated by using intervention meta-analysis criteria in Cochrane man-ual.Meta-analysis of joint depression,secondary collapse rate of articular surface,blood loss,operative time and infection rate between two methods were performed by Rev Man 5.3 software.Results Seven RCT studies(424 patients)were included,296 patients in bone replacement group and 128 patients in autograft group.Operative time[MD=-16.79,95％CI(-25.72,-7.85),P=0.000 2]and blood loss[MD=-70.49,95％CI(-79.34,-61.65),P＜0.000 01]between two groups had statistically differ-ences,while joint depression[MD=-0.17,95％CI(-0.91,0.58),P=0.66],secondary collapse rate of joint surface[RR=-0.74,95％CI(0.35,1.57),P=0.43],infection rate[RR=1.21,95％CI(0.31,4.70),P=0.78]between two groups had no differences.Conclusion The effects of bone substitute and autograft for the treatment of tibial plateau fracture have similar effects in terms of joint depression,secondary articular surface collapse rate and infection rate.However,compared with autologous bone trans-plantation,bone replacement could reduce blood loss and shorten operation time.
