Abstract

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 discretisation in finites elements.

There were raised tension and deformation diagrams for the meniscus subjected to different stresses. There are presented comparative diagrams for tensions, deformations and deforming energy for the normal meniscus, and, respectively, for the totally cut meniscus, with a third of the volume, or two thirds of the volume.

There were raised diagrams of the cinematic parameters (positions, speeds, accelerations) of the femur – lateral meniscus couple. Virtual models of the bony structures were subjected to different cinematic and dynamic simulations, separately, or in whole the human knee joint. Maps of tension were presented for the whole joint and for its components, to different movement moments.
