MOBILE BEARING KNEE PROSTHESIS

摘要

A knee prosthesis having a mobile may include a spherical radius interface comprised of a concave superior surface on a tibial tray (102) and a convex inferior surface on a tibial insert (104). The knee prosthesis may also include a spherical radius interface comprised of a convex superior surface on a tibial tray and a concave inferior surface on a tibial insert. The mobile bearing knee prosthesis can additionally include a bi-concave interface (e.g., having a "wave" like surface geometry).
