Simulace a vyhodnocování otěrových procesů pro UHMPE elementů náhrady kolenního kloubu

The demands on artificial knee joint replacement are steadily increasing. Major motivation of this research project, is to increase the lifetime of present prosthesis designs .The main problem of the commonly used UHMWPE / Steel–Implants is the appearance of polyethylene wear which leads to aseptic loosening and therefore to long-term prosthesis failing. In vitro simulations can be an important instrument to predict the wear behavior of new prosthesis designs and materials. ISO 14243 has been developed to obtain comparable results testing on different in vitro simulators. The aim of this study is to verify, how the simplifications made by the in-vitro simulations influence the simulation results and how today’s prosthesis testing can be made more realistic
