Synopsis

37 patients (40 knees involved) with osteoarthritis were randomized to receive either mobile-bearing or fixed-bearing total knee arthroplasty (TKA). This study examined weight-bearing kinematics of the knee at 1 year follow-up when performing step-up exercises in order to compare the two prostheses. Total extent of tibial rotation did not differ between the two groups, though the mobile-bearing gr...
