With the present thesis, a body model for clinical gait analysis was initially designed and evaluated on the basis of 25 subjects. A reduction of measurement errors for gait parameters and a more accurate determination of the knee joint axis compared to the conventional model could be detected. With this custom made model, the gait of 14 patients with varus malalignment of the knee 12-19 years of age was analyzed in a second experimental study. Varus malalignment occur concomitantly with biomechanical changes in gait pattern in the sagittal, frontal and transverse plane. Three-dimensional gait analysis is a diagnostic tool that can be used to gain a better understanding of the relationship between joint loading and the onset or progression of articular cartilage degeneration in patients with varus malalignment of the knee.
