The most common procedure for advanced osteoarthritis of the knee is a total knee arthroplasty (TKA). Unicompartmental knee arthroplasty (UKA) has become a popular treatment for isolated medial compartment osteoarthritis. The purpose of this study was to look at the functional outcomes following these two procedures. Prior to January 1995, 87 Miller-Galante UKAs (MG UKA) were performed in 68 patients. These were compared to a gender, age, BMI matched Anatomic Modular Knee (AMK) cohort of equal size performed during the same time period. Patients were evaluated using a validated clinical outcome score (Knee Society score) and radiographs. Kaplan-Meier survival analysis was performed.Purpose

The purpose of this study was to compare the outcomes and complications of normal weight, class one obese (BMI=30-34.9 kg/m2) and superobese (BMI≥50 kg/m2) primary total knee replacement (TKR) patients. Between January 1995 and December 2005, 4104 primary TKR were performed in our centre. Patients were stratified for their obesity level according the World Health Organisation (WHO) and current surgical literature classification. Sixty-seven superobese patients (group one) were identified. They were matched with normal weight (group two) and class one obese (group three) primary TKR patients for sex, age, side, preoperative diagnosis, implants used, time since surgery and preoperative SF-12 mental component summary score (MCS). Patient clinical outcomes (WOMAC, SF-12 and Knee Society scores), radiographs, complications, readmissions, and revisions rates were compared for normal BMI, class one obese and superobese patients.Purpose
