Objective: To observe the clinical effects of Oxford Ⅲ unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA) in the treatment of medial compartment osteoarthritis of the knee joint. Methods: The clinical data of 66 patients with medial compartment osteoarthritis of the knee admitted to the Fourth Hospital of Baotou from January 2018 to January 2021 were selected and divided into observation group and control group (33 patients in each group) according to different surgical methods. The observation group was treated with UKA, and the control group was treated with TKA. The surgical related indexes of the two groups were compared. The femoral-tibial angle (FTA) and range of motion (ROM) of the two groups were compared before and 1 year after operation. The pain and knee function were evaluated by visual analogue scale (VAS) and Hospital for Special Surgery knee score (HSS). And the complications of the two groups. Results: The operation time, incision length and hospitalization time of the observation group were shorter than those of the control group, and the intraoperative blood loss was less than that of the control group (P＜0.05). Before operation, there was no significant difference in FTA, ROM, VAS score and HSS score between the two groups (P＞0.05), while the FTA and VAS scores of the two groups at 1 year after operation were significantly lower than those before operation, and those of the observation group were lower than the control group (P＜0.05). At 1 year after operation, the ROM and HSS scores of the two groups were higher than those before operation, and those of the observation group were higher than the control group (P＜0.05). The total incidence of postoperative complications such as persistent pain, prosthesis shedding, joint stiffness, and lateral compartment osteoarthritis in the observation group (9.09%) was lower than that in the control group (30.30%) (P＜0.05). Conclusion: Compared with TKA, UKA has the advantages of less trauma, shorter operation time, less intraoperative blood loss and faster postoperative recovery in the treatment of medial compartment osteoarthritis of knee joint. Meanwhile, it can improve the femoral-tibial angle, knee joint mobility and knee joint function, effectively reduce the pain of patients, reduce postoperative complications and shorten the hospitalization time. Therefore, it is worthy of popularization and application.
