Abstract: A femoral augment, or set of augments, for use with a knee joint prosthesis, where the femoral augment includes a main body portion, an aperture formed within the main body portion and extending in a generally distal/proximal direction, and a pair of legs extending outwardly from said main body portion in a generally posterior direction. In the preferred embodiment, the aperture is configured to receive a stem extension implant, and to allow it to pass through. Additionally, the legs of the femoral augment are preferably configured to be seated proximal of a proximal side of a pair of condylar portions of a femoral component of a knee joint prosthesis. The present invention is intended for situations in which the distal portion of the femur is defective, and it provides a method and devices that allow for preservation of healthy peripheral bone, while still providing the necessary augmentation to the distal portion of the femur.

Abstract: A tibial augment for use with a knee joint prosthesis, composed of annular members of different stock sizes, each size being configured to fit within a cavity formed in a human tibia. The augment may include a stepped distal surface. A provisional (temporary) tibial augment used to ensure a proper fit for the permanent augment is also provided. The provisional may include grooves configured to cooperate with a set of ribs on a tong-like holder used for removing the provisional from the cavity. A pusher for use implanting the tibial augment is also provided. In addition, a system for creating a cavity in a human tibia is also described. The system preferably includes a guide with a slot therein and a set of osteotomes that are inserted to within different portions of the slot. Methods for using the tools and/or implanting the prosthetic devices discussed above are also described.

Abstract: A method of preparing the proximal tibial and distal ends of the femur for the implantation of prosthetic components, including the steps of exposing the joint; resecting the distal end of the femur; resecting the tibia; and making a preliminary rough cut of a posterior portion of the pair of condyles. The rough cut is made by positioning a guide on the distal end of the femur and severing a small piece of the posterior portion of the pair of condyles. The rough cut is made prior to the step of resecting the tibia. The method may include finishing the femur by severing and removing a final piece of the posterior portion of the pair of condyles. The small piece removed in the preliminary rough cut step is sized to preserve enough of posterior portion to permit the removal of the final piece.

Abstract: A prosthetic system that includes a prosthetic implant and a support structure secured to an inner surface of a cavity of a bone is disclosed. The support structure defines a channel that extends through the length of the support structure. The prosthetic implant is received in the channel, and a portion of the prosthetic implant is secured to an inner surface of the support structure by an adhesive. The support structure may comprise a pair of partially hemispherical components arranged in spaced apart relationship thereby defining the channel between the pair of components.
