This review deals with the stress strain analysis of the normal tibio-femoral joint in its basic position (extension). On the basis of the analysis, a contact pressure between a femoral and tibial cartilage and femoral cartilage and meniscus has been obtained. The geometry of bones (tibia and femur) was described by computer tomography and the shape of cartilage and meniscus was created with the aid of literature [1], [3], [16]. The system was loaded by displacement. Following the Ansys analysis, force representing the load within the knee joint area has been determined. and Obsahuje seznam literatury
