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 modular implant system includes a baseplate, a bearing insert and a latch. The baseplate is adapted to receive the bearing insert. The bearing insert has an articular surface and a plate-contacting surface opposite the articular surface and the latch is adapted for disposal through a hole in the bearing insert. The system is adapted so that when the plate-contacting surface of the bearing insert is disposed on the baseplate and the latch is disposed through the hole in the bearing insert, the latch is rotatable from a first position to a second position. In the first position, the bearing insert is removable from the baseplate. In the second position, the bearing insert is held in place on the baseplate.

Abstract: A tool for implanting an orthopedic implant upon a bone includes a body defining an implant socket for releasably retaining an implant and a drill guide opening into the implant socket. The body is an insert receivable in an insert socket of a movable end of the tool. The tool also includes a tip toward which the implant socket faces and opposedly movable relative to the body. The tool is usable in a process that includes clamping a bone between the tip and the implant while the implant is retained in the implant socket. While the bone is clamped, a drill is driven through the drill guide to produce a hole in the bone.

Abstract: A method of forming a bone void for receipt of a prosthesis, comprising the steps of: inserting a stem of a reaming guide assembly into an intramedullary canal of a bone, the reaming guide assembly having first and second reamer guides disposed adjacent to each other, the first and second reamer guides being connected to an end of the stem; reaming the bone through the aperture of the first reamer guide to form a first bone void; inserting the lobe trial into the first bone void; and reaming the bone through the aperture of the second reamer guide to form a second bone void.

Abstract: Disclosed herein are apparatuses and methods for performing joint balancing procedures. The apparatus may have femoral paddle and a tibial paddle attached to a housing. The housing may include a distraction mechanism to vary the space between the femoral paddle and the tibial paddle. The tibial paddle may lie entirely within the femoral paddle in a closed position. A load sensor may be placed in the femoral paddle to measure ligament tension. The apparatus may be inserted into a knee joint and positioned to remain within the knee joint during flexion and extension of the knee without everting a patella.

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 varus-valgus alignment instrument includes a body having a bone contact surface for contacting a distal femur and an opening extending through the body and bone contact surface. The opening is sized to receive an elongate shaft therein. An alignment member is moveably attached to the body and has first and second openings therethrough. The first and second openings are sized to receive the elongate shaft and are interchangeably positioned in alignment with the opening of the body.
