Abstract
An endoprosthetic knee joint device is suited to a unicondylar procedure in which only one compartment of the knee is treated, or a duocondylar procedure, the latter employing a pair of like femoral components and a tibial component having a common platform defining separate recesses for similar pads. In addition the device maximizes the use of advantageous material properties, allows pad replacement in the event of wear, and allows pad thickness selection to correct for varus and valgus deformities.
