Unicompartmental knee arthroplasty (UKA) is a surgical pro cedure that selectively replaces only the damaged compartment of the knee for the treatment of osteoarthritis. It has specific and narrow indications, and treatment success is highly dependent on the surgeon's skill and implant selection. In addition, it is tech nically difficult to perform, early failure rates are relatively high, and the longterm survivorship of UKA has not yet been exten sively studied 1,2). The theme of this issue of the Knee Surgery & Related Research (KSRR) is UKA. The current issue contains three original articles on this theme. In one article, Kim et al. described the longterm clinical results of UKA in patients younger than 60 years of age. Another article by Cho et al. focused on the design of implant and surgical technique of UKA. The last article by Ryu et al. com pared the clinical and radiographic outcomes of HTO and UKA in relatively young patients with unicompartmental arthritis of the knee. The traditional indications for UKA include degenerative ar thritis of the knee affecting one compartment, >60 years of age, body weight <82 kg (180 lb), lowdemand for activities, range of motion ≥90°, flexion contracture ≤5°, angular deformity <15°, and absence of symptoms and signs of inflammatory arthritis 3). However, the indications have continued to expand with recent advancements in surgical techniques and implant designs. As a re sult, UKA is currently considered a viable option in most patients regardless of age, activity level, and weight 4,5). Although the indica

PurposeTo evaluate the long-term clinical results and survivorship of unicompartmental knee arthroplasty (UKA) in patients younger than 60 years of age.Materials and MethodsOne hundred and six cases of medial UKA with a minimum follow-up of 10 years were selected for this study. There were 80 patients and the preoperative diagnosis was osteoarthritis in all cases. The mean age of the patients was 54.2 years and the mean duration of follow-up was 12.1 years. Clinical assessments were performed using the Knee Society clinical rating system, and a survival analysis was performed using the Kaplan-Meier method.ResultsThe mean knee and function scores improved from 52.8±8.4 points and 56.6±10.6 points preoperatively to 85.4±9.1 points and 84.7±10.4 points at the last follow-up, respectively (p<0.001). The mean range of motion was recovered from 130.7° to 132.8° at the last follow-up. Complications occurred in 20 cases (16.7%) and the most prevalent complication was mobile bearing dislocation (n=9, 7.5%). The 10-year survival rate was 92.8% when conversion to total knee arthroplasty was defined as failure, whereas 89.3% when failure was defined as all revision surgeries.ConclusionsThe long-term clinical results of UKA were satisfactory in patients under 60 years of age. Therefore, UKA could be a useful method for the treatment of medial compartment osteoarthritis of the knee in patients younger than 60 years of age.
