OBJECTIVE: To assess the efficacy of UKA versus HTO in the treatment of unicompartmental knee osteoarthritis. METHODS: Comparative studies of UKA and HTO were retrieved from the domestic and foreign literatures and included for a meta-analysis. RESULTS: Seven 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). CONCLUSION: UKA reduces the risk of postoperative revision and complications and provides excellent outcomes.
