Abstract: BACKGROUND: Unicompartmental knee arthroplasty and high tibial osteotomy are two effective methods for the treatment of medial compartment osteoarthritis of the knee. However, there is still a lack of medium and long-term efficacy observation, and there is no study to analyze and compare the postoperative kinematic parameters of the two.
OBJECTIVE: To investigate the clinical efficacy and kinematic parameters of unicompartmental knee arthroplasty and high tibial osteotomy in the treatment of medial compartment osteoarthritis of the knee.
METHODS:  Clinical data of 97 patients with osteoarthritis in the medial compartment of the knee who were admitted to the Department of Orthopedics, Foshan Hospital of Traditional Chinese Medicine from January 2016 to June 2017 and met the inclusion criteria were retrospectively collected. According to different surgical methods, they were divided into two groups, including 49 cases in unicompartmental knee arthroplasty group and 48 cases in high tibial osteotomy group. The range of motion, Lysholm knee score, Tegner knee motion score and tibiofemoral angle of the two groups were recorded and compared before operation and 1, 2, 3 years after operation. Simultaneously, Opti-Knee three-dimensional motion analysis system was used to record the three-dimensional six degree of freedom range of motion of knee joint during gait before and 1, 2, 3 years after operation.  
RESULTS AND CONCLUSION: (1) Both groups of patients healed by first intention and had no complications related to endophytes. All patients were followed up. (2) The range of motion, Tegner knee score, Lysholm knee score, tibiofemoral angle and knee kinematics parameters of the two groups were significantly improved 3 years after operation (P < 0.05). However, there was no significant difference in above indexes between the two groups (P > 0.05). (3) It is suggested that both unicompartmental knee arthroplasty and high tibial osteotomy can effectively improve knee joint function and correct deformity, and can effectively improve gait parameters for patients with medial compartment osteoarthritis of knee joint. The curative effect of the two methods is similar, but the long-term efficacy needs further study.
