Abstract:
AIM: To analyze gait of patients undergoing total knee arthroplasty by three-dimensional (3D) biomechanical approach. METHODS: Fifty-three patients undergoing total knee arthroplasty were selected from Zhongshan Hospital of Dalian University between November 2005 and November 2006, with average age of 59.2 years (range, 42-82 years). The subjects consisted of 33 males with average height of (172?13) cm and body mass of (64?11) kg, and 20 females with average height of (155?11) cm and body mass of (45?1l) kg. All patients were evaluated by 3D gait analysis motion analysis system (DVMC-8801), of which three step lengths at constant gait speed were measured. Sixteen points were set up around hip, knee and ankle and connected to build up 3D dynamic image. RESULTS: Gait speed, gait frequency, step length and affected limb standing phase were all significantly improved postoperatively (P
