Abstract
The durability of a total knee endoprosthesis – especially in younger, active patients, is due to increased higher stresses insufficient. Accordingly, implant-associated wear particles lead to aseptic endoprosthesis loosening as a result of osteolysis and thus to premature failure of the endoprosthesis. Amorphous carbon coatings can meet the high requirements for implants. They combine tribologically effective behavior with high biocompatibility and excellent mechanical properties. The focus of this work was on the application and the mechanical-biotribological preclinical in vitro investigation of amorphous carbon coatings on metallic/polymeric articulation partners of endoprostheses. Using rheological investigations and numerical simulations, an application-related, biotribological test chain consisting of a ball-on-three-pin tribometer, pin-on-disk tribometer and fully kinematic knee simulator was established. This test chain allowed a comprehensive wear analysis of numerous contact combinations in a reasonable time with respect to dominant wear mechanisms, typical particle sizes and morphologies, as well as their correlation across the test links. In all test links, the biotribological effectiveness of the amorphous carbon coatings was shown, indicating a significant increase in the service life of endoprostheses.
