  • Patent number: 10893947
    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.

  • Publication number: 20180098856
    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.

  • Patent number: 9539096
    Abstract: Methods for supporting a prosthetic implant in a patient are disclosed. In some embodiments, a hollow sleeve and a prosthetic implant with a stem component are implanted in a cavity in an end of a bone where the hollow sleeve provides an axial channel that extends through the length of the hollow sleeve for receiving the stem component. In some embodiments, the hollow sleeve is capable of being impacted into the cavity for obtaining a press fit of the hollow sleeve in the cavity. In some embodiments, the hollow sleeve is formed with a porous material.
