Abstract
Objectives:
This study aims to provide a comprehensive comparative analysis of functional outcomes between Unicompartmental Knee Arthroplasty (UKA) and Total Knee Arthroplasty (TKA) in patients diagnosed with bilateral knee osteoarthritis. Both procedures were performed simultaneously on separate knees to evaluate their respective efficacy.
Methods:
The study included 25 patients (18 women, 7 men) with a mean age of 59.6 years, all meeting criteria for UKA in one knee and TKA in the other. Radiographic and clinical data were collected over a two-year period, with assessments conducted at 6 months, 1 year, and 2 years postoperatively. Data included age, gender, BMI, medical history, surgical procedures, and various scores and measurements related to knee function.
Results:
The UKA group exhibited significant improvements in functional scores compared to the TKA group. Specifically, the WOMAC score for the UKA knee was 24.5% higher than that of the TKA knee, indicating better functional outcomes. Radiographically, the tibiofibular angle was more than two times greater in the UKA method, while the varus angle was significantly greater in the TKA method. No postoperative complications were reported.
Conclusion:
This study underscores the safety and efficacy of both UKA and TKA procedures in the treatment of bilateral knee osteoarthritis. UKA demonstrated superior functional outcomes, while TKA displayed distinct advantages in radiographic alignment. Individual patient characteristics and preferences should guide the selection of the most appropriate surgical approach.
