PROBLEM TO BE SOLVED: To provide a unicompartmental mobile tibial assembly including a tibial tray and a tibial insert. SOLUTION: The tibial tray 12 includes an upper surface 24 and a bottom surface 26 configured to contact a portion of a surgically-prepared surface of the proximal end of a tibia. The tibial insert 14 includes an upper bearing surface 69 configured to contact a surgically-prepared surface of the distal end of a femur and a bottom bearing surface 70 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.
