Numerical Simulations of the Virtual Human Knee Joint

In this paper we are presenting the results of the research based on dynamic simulation of human knee virtual model. Starting from the parts realized with computer tomography help, there were realized virtual models for the femur, tibia, meniscus and ligaments that form the complex human knee joint, and their meshing in finite elements. There are presented comparative stress diagrams for the normal walking and for the case of sectioned anterior crisscross ligament.Maps of stress are presented for the whole joint and for its components, to different movement moments. 3DP rapid prototyping technology is used to obtain the components of the human knee joint necessary for future experimental research.
