JOINT PROSTHESIS ABSTRACT An implantable joint prosthesis comprising a metal tray and rigid plastic insert removably fitted into the tray. The tray has an upper surface and a lower surface. The lower surface has at least one stem for insertion into a human bone. The upper surface of the metal tray has a generally flat continuous central region and an upwardly extending wall enclosing the major portion of the central region. Recesses are provided adjacent the base of the wall on opposite sides of the tray. The rigid plastic insert has a generally flat continuous lower surface and a first and second tab at the lower edge of the insert at a location which corresponds to the recesses in the tray. A narrow slot is provided in the lower surface of the insert and spaced immediately behind at least the first tab to allow the first tab to deflect when the insert is forced into the tray.
