Zusammenfassung:A joint prosthesis includes a first prosthesis member having an inferior bone contacting surface, a second prosthesis having a superior bearing surface and a cushion member disposed between the two prosthesis members. The joint prosthesis is particularly useful for replacing bi-condylar joints and especially knee joints. The joint prosthesis is characterized by its high bearing surface contact area and low peak stress which is maintained even under malalignment conditions.
