Abstract:

In the context of the development of the Munich Knee Joint Simulator (MKS) a mathematical description of the biomechanical aspects of the intact and pathological knee joint is required. This article presents a biomechanical model of the knee joint, which consists of inertial, gravitational, elastic, and friction forces and moments. The mathematical description of the said forces / moments as functions of the displacement is based on mechanical properties, data from literature, own measurements and heuristics. For identifying the elastic properties of varus-valgus and flexion-extension degree of freedom measurements with a robot-based approach were performed at a human cadaver knee joint. The biomechanical model of the knee joint was formulated in a way that meets the requirements for implementing in the simulation environment of the Munich Knee Joint Simulator.
