<p>This invention relates to an improved total knee prosthesis of the non-hinged type which advantageously provide normal knee motion and stability during ambulation while substantially obviating loosening or cold flowing of the tibial component. For this purpose, the total knee prosthesis substantially adopts the anatomical configuration of the natural knee and includes a tibial component comprising condylar bearing members with lower portions completely embedded in tray-shaped elongated sections, in which they are mounted with a predetermined clearance to mechanically absorb part of the natural stresses and torques. The condylar bearing members are also removable and replaceable to obviate any misalignment, natural or not.</p> |
