Abstract

The present invention provides an implant for replacing an articulating bone end adjacent a skeletal joint. The implant includes individual subcomponents having different physical and/or mechanical properties joined together into a multipart implant component.

Claims (3)

1. A tibial implant for a knee joint, the implant comprising:
first and second bearing portions, each of the first and second bearing portions including an articular surface; and an intercondylar portion interposed between the first and second bearing portions, the first bearing portion, second bearing portion, and intercondylar portion forming three separate subcomponents mechanically joined together to form a single component.
2. The implant of claim 1 wherein the first and second bearing portions each have a first predetermined toughness value and the intercondylar portion has a second predetermined toughness value greater then the first predetermined toughness value of the bearing portions.
3. The implant of claim 1 wherein the intercondylar portion comprises a tibial tray including a tibial eminence, the first and second bearing portions being received by the tray with the eminence interposed therebetween.
