Abstract
A modular knee prosthesis can include a femoral component having a superiorly extending portion, a first femoral bearing surface and a second femoral bearing surface. The superiorly extending portion can define a first tapered augment receiving surface. A tibial component can have an inferiorly extending portion and a tibial bearing surface. The inferiorly extending portion can define a second tapered augment receiving surface. A first augment can define a first receiving bore and a first stepped surface. A second augment can define a second receiving bore and a second stepped surface. The first and second augments are adapted to mate at the first and second stepped surfaces in a first position at the first tapered augment receiving surface of the femoral component and in a second position at the second tapered augment receiving surface of the tibial component.
