Abstract:

Objective To compare the efficacy of unicondylar replacement and high tibial osteotomy in the treatment of osteoarthritis of the medial compartment of the knee. Methods We selected 40 patients with medial compartment osteoarthritis of the knee in our hospital from January 2017 to December 2020 as the research objects. According to patient′s wishes，they were divided into unicondyle replacement group and high tibial osteotomy group with 20 cases in each. The two groups were compared in terms of inflammatory cytokines，knee joint range of motion，knee joint function score，quality of life score，and complication rate. Results There was no significant difference in knee range of motion，knee function scores，and quality of life score between the two groups before surgery（P > 0.05）. Knee range of motion，knee function scores，and quality of life scores were all higher 1 month after surgery and the difference was statistically significant（P < 0.05）. The quality of life score in the two groups showed nostatistical significance（P > 0.05）. Knee joint function score was higher inunicondyle replacement group than that in the high tibial osteotomy group，and the difference was statistically significant（P < 0.05）. The compli⁃ cation rate of the two groups was the same，indicating no statistical significance（P > 0.05）. Conclusion In clinical treatment of osteoarthritis of the medial compartment of the knee，unicondyle replacement is more helpful than high tibial osteotomy to improve knee joint function，but its disadvantage is that the knee joint has poor mobility.
