Modelling of the knee joint arthroplasty

Abstract eng:
From the point of view of the knee joint mathematical modelling, the interest has to be focused to kinematic and geometric relations of the link between femur and tibia (relative motion), static and dynamic loading of this complex (especially the contact force) and tribilogical relations of the artificial knee joint replacement. Application for the synovial fluid flow modelling in the total knee alloplastic is presented. The model is simplified as a planar model and the pressure distribution due to the interaction between femur and tibia in the synovial fluid is computed. The investigated area is defined by the articular cavity between femoral and tibial condyles. The pressure distribution in the total knee replacement is presented at the end of this article
