Abstract
Osteoarthritis in the hip or knee is one of the most common diseases in industrialized countries. The implantation of an endoprosthesis as a joint replacement represents the most effective way to treat serious pathological changes in these joints. The lifetime of an endoprosthesis can be shortened by aseptic inflammation and osteolysis. The main cause for the aseptic inflammations, osteolysis, and thus, the failure of the endoprostheses are abrasion particles of the acetabular cup inlays that are caused by the tribological load of the prosthesis. This research project aims at developing coatings with enhanced tribological behaviour for endoprostheses by an active hydrodynamic lubrication of the joint with synovial fluid. In addition, biocompatibility, as well as the increase of the strength under static and cyclic loading need be realized. In the current approach, a deterministic fluid flow tube structure is formed in a thermally sprayed alumina layer by the introduction of a leachable placeholder. This tube structure allows the transverse transport of the synovial fluid through the alumina layer. Furthermore the synovial fluid can be transported into the lubricating gap of the sliding surfaces by leaving the alumina layer through the porous surface. First results will be presented and the ramifications in correlation to applications will be discussed.
