<p>A one-piece hybrid tibial tray component (10) of a knee replacement prosthesis includes a laterally extending plate (11) having a proximal surface (13), a distal surface (14) which includes a peripheral surface (15) for receiving bone cement and a central surface (16) which promotes bone ingrowth and a central stem (19) 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.</p> |
