The paper presents the numerical analysis of stress and strain occuring in the most wearable parts of hip and knee joint endoprostheses. In the hip joint that would be the pair: the head - cup, and in the knee joint: sled - insert. The complexity of the processes taking place both in natural and artificial joint make is necessary to conduct the analysis on the 3D model and basing on already existing mathematical models. Finite elements method makes it possible to calculate the stress in particular elements of the tested model.
