Abstract :
Computer-based biomechanical modeling and simulation of human organs and their functionality have made a great impact on the field of medicine in the last decade. In this paper we will focus on modeling and simulating the kinematics of the human knee joint. Three-dimensional models of a knee are generated from magnetic resonance acquisitions at varying flexion angles. They include more than 40 different anatomical structures like the femur, tibia, patella, ligaments, menisci and muscles. Using collision detection algorithms, deformable models as well as force-feedback devices, the kinematics of the knee joint are simulated
