Abstract

The purpose of this study was to evaluate outcome of bilateral total knee arthroplasties (TKA's) in two groups of patients: Group A had simultaneous arthroplasty of both knees, and Group B had staged bilateral arthroplasty.Bilateral (TKA's) were performed in fifteen patients with severe rheumatoid arthritis (4 cases) and osteoarthritis (11 cases). Group A (8 patients) had both knees replaced simultaneously in one operation. Group B (7 patients) had two operation in a staged procedure. The postoperative mobility was analyzed in the two groups of patients who were similar with respect to age, type of arthritis, preoperative range of motion, and postoperative management.In this small series of cases there was a significantly shorter hospitalization period, and cheaper costs in Group A.
