Abstract

The invention relates to a mobile bearing assembly having a non-planar interface, specifically provides a unicompartmental mobile tibial assembly which includes a tibial tray and a tibial insert. The tibial tray includes an upper surface and a bottom surface configured to contact a portion of a surgically-prepared surface of the proximal end of a tibia. The tibial insert includes an upper bearing surface configured to contact a surgically-prepared surface of the distal end of a femur and a bottom bearing surface configured to contact the upper surface of the tibial tray when the tibial insert is coupled to the tibial tray. Any one or more of the upper surface of the tibial tray, the bottom surface of the tibial tray, and / or the bottom bearing surface of the tibial insert may be non-planar.
