Biomechanics of human knee joint under dynamic conditions

Abstract

Incorporation of numerical methods to analyze the biomechanical behaviour of a human knee joint is the conventional practice. The biological joint simulation studies require incorporating the material, and geometric non-linearities while developing a numerical model. In case of biological joint dynamic analysis, the preprocessing of Finite Element models will be a challenging job and needs huge computational requirements. As the biological tissues are highly non-linear, obviously the researchers face difficulties in handling material and geometric nonlinearities. The aim of this study is to evaluate the contact mechanics behaviour of a human knee joint under various loading conditions. This study explores contact parameters in line with contact mechanics approach, which deals with frictional stresses at the contact interfaces of the knee joint, identifying the failure prone zones in the corresponding soft tissues, and modal response of the knee joint. This study provides the biomechanical characteristics of a human knee joint contact interactions that can be used as a surrogate models in complex dynamic simulations.
