Abstract
The invention relates to an articular resurfacing implant which is characterized in that it is composed of a sheet (1) of pyrolytic carbon deposited on a graphite substrate and a layer (8) composed of an adhesive elastomer or polymer material adherent to the inner surface of the sheet (1) on the substrate side. The adhesive elastomer or polymer material layer (8) allows the implant to be adherent to bone (3) and acts as a shock absorber layer. In one embodiment the implant further comprises a hard material, e.g. metallic, sheet (4).
