Posterior stabilized knee system prosthetic devices employing diffusion-hardened surfaces |
摘要 |
An orthopedic implant with a diffusion-hardened surface on non-load bearing areas of the implant for interaction with non-load bearing surfaces of a polymeric bio-compatible material, such as UHMWPE. The orthopedic implant is a posterior stabilized knee prosthetic and system where a coating of oxidized zirconium is formed in the cam of the femoral prosthetic for interaction with the central post of a polymeric tibial insert. The diffusion-hardened surface of the orthopedic implant provides a strengthened cam and reduction in wear in the central post of the polymeric tibial insert.
