Patient outcomes in Anteromedial Osteoarthritis Patients over 80 Years Old Undergoing Oxford Unicompartmental Knee Arthroplasty in China

Abstract

Background: Oxford Unicompartmental Knee Arthroplasty (UKA) has increased rapidly around the world, and the effectiveness and safety of a minimally invasive surgical approach for it demonstrate excellent outcome. Oxford UKA represents an interesting solution for older patients. The aim of our study is to evaluate the perioperative complications and short-term clinical outcome and analyze the safety for older patients who undergo Oxford UKA.Methods: A retrospective review was performed of all patients who underwent Oxford UKA between June 2015 and January 2018. We divided all patients into three groups (ages 60-69; ages 70-79; age over 80). We used the HSS score and WOMAC score to evaluate the general condition of the patients' knees. We also recorded perioperative complications and long-term complications.Result:60 patients (60 knees) between the ages of 60 and 69 (Group 1), 70 patients (79 knees) between the ages of 70-79 (Group 2) and 65 patients (70 knees) over 80 years old (Group 3) were included in the study. The mean follow-up was 21.34±12.04, 22.08±11.38 and 21.76 ± 10.20 months in Group 1, 2 and 3, respectively. At last follow-up, the patients in Group 3 showed lower function scores as compared to group 1 and 2 (P <0.05), but both the HSS score and the WOMAC score were significantly improved in both groups after surgery. The rate of perioperative complications and other complications in elderly patients is the same as in younger patients. Conclusion:Oxford UKA is an effective and safe treatment for osteoarthritis, even in old adult patients in China. The knee joint pain symptoms of the elderly patients are relieved and the function is improved, but the function is still poor compared with the younger patients.

Spinal Versus General Anesthesia for the Outpatient Unicompartmental Knee Arthroplasty: A Randomized Controlled Trial

“…Unicompartmental knee arthroplasty (UKA) is a safe and effective intervention for end-stage knee arthritis con ned to the medial compartment [1] [2]. Compared with total knee arthroplasty (TKA), preservation of cruciate ligaments and less bone loss allowed UKA to attain a earlier recovery, less perioperative complications, and a better range of motion(ROM) of knee [3] [4].…”
