Abstract
In one aspect of the invention, an implant includes first and second components to replace a portion of each of a pair of opposed articulating bone ends. The second component has means for low friction articulation with the first component and means for engaging the first component to constrain the motion between the components. The means for low friction articulation includes a first material exhibiting low wear and having a predetermined toughness value. The means for engaging includes a second material having a predetermined toughness value higher than the means for low friction articulation.
