ABSTRACT:
A one-piece hybrid tibial tray component of a knee replacement prothesis includes a laterally extending plate having a proximal surface, a distal surface which includes a peripheral surface for receiving bone cement and a central surface which promotes bone ingrowth and a central stem extending from the distal surface and which is perpendicular thereto. The distal surface is adapted to fit against the upper end of a patient's tibia as part of a knee replacement surgical procedure and provides both initial fixation via the cement bonding as well as long term fixation due to bone ingrowth.
