endoprosthesis of knee joint
Opis:: The paper presents analysis of stress distribution in the friction node of knee joint endoprosthesis where sleds are made of various titanium alloys and CoCrMo cooperate with spherical polyethylene inserts. Currently used titanium alloys consists of Nb, Ta, Zr or Mo and with lesser value of Young’s modulus than Ti6Al4V alloy, or steel CoCrMo, which significantly varies from other metal materials. The obtained results make it possible to indicate the “weak points” of the accepted solution, and thus counteract the subsequent effects resulting from premature wear of endoprosthesis elements. The analysis was conducted with numerical method of ADINA System 8.6. The Finite Elements Method allowed to compute and present stress distribution quickly in all elements of the model.

Opis:: The paper presents the numerical analysis of stress and strain occurring in the most wearable parts of knee joint endoprostheses. In the knee joint that would be the pair: sled - flat insert. The complexity of the processes taking place both in natural and artificial joints makes it necessary to conduct the analysis on the 3D model and base it on already existing mathematical models. Finite elements method makes it possible to calculate the stress in particular elements of the tested model. The interaction between the two parts of endoprosthesis takes place on a comparatively small contact surface. The material on that surface is under a spatial state of stress and its stress distribution is very complex and can be designated only as resilience theory. High stress caused by pressure between the two parts is called contact stress.
