The main objective of the Action is to develop materials for improved wear resistance of artificial
joints and novel low wearing designs. For this purpose, the biotribology of materials in artificial
hip and knee joints, the mechanisms of lubrication and wear, the methods of in vitro simulation and
testing, and the resulting biocompatibility and biological reactions to the wear products will be
investigated in order to contribute to the standradising of in vitro simulation and testing. This
development will furthermore result in reduced wear particles, lower adverse biological reactions
and longer lifetimes of artifical joints and natural joints.
