Segmented lateral, medial femoral condyles with fitted ellipsoids of the geometry-based knee model.
Abstract :
In this paper, we present a comparative study between two knee joint models. The two kinematical models are analyzed on a gait motion, and we evaluate their influence on the joint reaction forces. The first model is mainly based on the femoral and tibial geometries of the subject while the second one lies on statistical properties. We show that we are able to predict the lateral, anterior and longitudinal moments.
