Tibio-femoral kinematics of the healthy knee during functional gait activities

Healthy tibio-femoral kinematics are controversially discussed in the literature. In this study, 10 healthy subjects were assessed throughout dynamic functional gait activities using a moving fluoroscope to establish physiological healthy knee kinematics. Significantly larger range of anterior-posterior (A-P) translation was found for the lateral condyle compared to the medial condyle for level walking as well as stair descent. Nevertheless, subject specific movement patterns were evident and let to larger A-P translation of the medial condyle for two subjects.
