Abstract
Joint endoprosthesis with a prosthesis part which on one side forms a slide surface (1), on the other side is to be connected to the bone without any bend-resistant intermediate spacer, and is made of a polymer material which favors sliding, such as polyethylene. The prosthesis part has a centrally situated area (3) in which it is mainly exposed to the loading and wear. The prosthesis part is essentially plate-shaped. It contains a reinforcement element which exhibits tensile strength, surrounds the main area of loading and wear and lies at least partially within the third of the thickness remote from the slide surface.
