Abstract: A distal femoral joint replacement system includes a femoral component having condylar articular surfaces, a stem extending from the femoral component, and a void filler for filling a bone void within a femur. The void filler includes a body and a plurality of legs extending from the body. The body has a sidewall defining an opening for receipt of the stem which extends along a length of the body and extends through the sidewall so as to form a side-slot in the sidewall that extends along an entire length of the sidewall. The plurality of legs each have a first end connected to the body and a second end remote from the body. The legs each have an outer surface that tapers between the first and second ends and is configured to register with a corresponding inner surface of a bone void when implanted in an end of the femur.

Abstract: A hinge knee system includes a tibial assembly having a baseplate component and an axle component. The baseplate component has an opening that extends therein from a proximal end toward a distal end thereof. The axle component has a shaft portion receivable within the opening of the baseplate component and an axle connected to the shaft portion that extends in a direction transverse to a longitudinal axis of the shaft portion. The system also includes a femoral assembly that includes a distal femoral component. The distal femoral component includes condylar portions and an intercondylar portion disposed between the condylar portions. The intercondylar portion includes a bearing surface that defines a recess configured to rotatably receive the axle for articulation therewith.

Abstract: A knee joint distractor includes a handle that has a length that extends along a longitudinal axis of the knee joint distractor and a distraction head connected to the handle. The distraction head has a femoral contact side and a tibial contact side. The femoral contact side has a first femoral contact portion. The tibial contact side has first and second tibial contact portions. The first tibial contact portion defines an inferior apex of the tibial contact side. The second tibial contact portion has a plurality of teeth offset from the inferior apex in a direction toward the handle.

Abstract: A joint prosthesis system includes a femoral component that has an articular side, a bone facing side, and medial and lateral condylar portions. The medial and lateral condylar portions at least partially define an intercondylar recess located therebetween and have a first concave surface extending in a mediolateral direction across the medial and lateral condylar portions. A first modular component has a second concave surface and is connectable to the femoral component such that, when the first modular component is connected to the femoral component, the first and second concave surfaces come together to form a transverse opening extending in the mediolateral direction. A first tibial assembly has a baseplate component and a head extending therefrom. The head defines an axle opening that extends therethrough. An axle is configured to be received within the transverse opening and axle opening so as to connect the tibial assembly to the femoral component.
