title: Fluoroscopic and gait analysis of the functional performance in stair ascent of two total knee replacement designs.
abstract: Understanding total knee replacement mechanics and their influence on patient mobility requires accurate analysis of knee joint kinematics and traditional full body kinematics and kinetics. Three-dimensional fluoroscopic and gait analysis techniques were carried out on patients with either mobile bearing or posterior stabilized knee prostheses during stair ascent. Statistically significant correlation was found between knee flexion at foot strike and the position of the mid-condylar contact points, and between maximum knee adduction moment and corresponding lateral trunk tilt. A more complete and powerful assessment of the functional performances of different TKR designs can be performed in-vivo by combining gait and fluoroscopic analyses.
