Abstract
An improved knee prosthesis includes a ceramic tibial component for articulation with natural or prosthetic (re-surfaced) femoral surfaces. The ceramic tibial component is provided in the form of a ceramic monoblock adapted for fixation relative to the patient's tibial bone, or alternately in the form of a ceramic bearing insert component carried by a tibial baseplate member which is adapted in turn for fixation relative to tibial bone. In either form, the ceramic tibial component includes at least one upwardly concave articulation surface for movable bearing engagement by a generally convex or condylar shaped femoral articulation surface. The ceramic tibial component provides improved wear characteristics with extended service life.
