- Discussion:
- femoral component is made of chrome colbalt alloy w/ its proven wear characteristics articulating with high density poly ethylene;
- tibial & patella components are metal backed w/ titanium alloy;
- enhance fatigue strength of titanium decreases potential for stress fracture of the metallic tibial tray;
- in metal back patella component, the use of titanium allows thicker polyethylene to decrease the chance of failure by wearing through of
polyethylene surface
