发明名称 IMPLANTABLE KNEE JOINT PROSTHESIS CONVERTIBLE FROM PRIMARY TO REVISION
摘要 <p>An implantable orthopedic knee joint prosthesis includes a femoral component (10) having an internal box geometry defined by bone-engaging surfaces (38, 40, 42, 44, 46) configured as a primary prosthesis. The femoral component has a threaded bore (74) through the bone-engaging surface. An adapter (50) has a mating surface (64, 66, 68, 70) complementary to the box geometry of the femoral component and is configured as a revision prosthesis. A hole (72) through the adapter is aligned with the threaded bore of the femoral. An adapter screw (52) holds the adapter to the femoral component. A spacer (100) has a mating surface (104, 106, 108, 110) complementary to the adapter. A screw (102) holds the spacer to the adapter.</p>
