    ObjectiveTo assess the efficacy of UKA versus HTO in the treatment of unicompartmental knee osteoarthritis.MethodsComparative studies of UKA and HTO were retrieved from the domestic and foreign literatures and included for a meta-analysis.ResultsSeven eligible randomized controlled trials included 196 UKAs and 219 HTOs. The result of Meta-analysis indicated that the ratio for an excellent outcome was higher in UKA than HTO. The combined OR was 2.43, 95%CI (1.46, 4.05) (P = 0.0006). The risks of revision and complications were lower in UKA than HTO. The combined OR was 0.47 and 0.24 and 95%CI (0.23, 0.97), (0.10, 0.56).ConclusionUKA reduces the risk of postoperative revision and complications and provides excellent outcomes.
