177 Robotic Assisted Versus Conventional Unicompartmental Knee Arthroplasty: A Systematic Review and Meta-Analysis

Abstract Aim To compare the robotic-assisted unicompartmental knee arthroplasty (UKA) with conventional UKA. Method We systematically searched on four databases till September 2021. The outcomes were pooled as mean difference (MD) or standardized (SMD) risk ratio (RR), and 95% confidence interval. used RevMan to perform analysis. Results There 22 included studies. no significant differences between UKA one in satisfaction rate (RR=1.05, CI [0.98, 1.14], p=0.19), complication (RR=0.62, [0.32, 1.19], p=0.15), range of motion (MD= -0.23, [-5.76, 5.30], p=0.93). However, showed favouring outliers limb alignment (RR= 0.46, [0.29, 0.74], p=0.001). On other hand, had better surgical time than robotic assisted (MD=20.89, [11.87, 29.90], p<0.00001). Conclusions mainly several such rate, others. significantly favoured tibial alignment, but prolonged group.
