  • Patent number: 7320709
    Abstract: A method and system for the creation or modification of the wear surface of orthopedic joints, involving the preparation and use of one or more partially or fully preformed and procured components, adapted for insertion and placement into the body and at the joint site. In a preferred embodiment, component(s) can be partially cured and generally formed ex vivo and further and further formed in vivo at the joint site to enhance conformance and improve long term performance. In another embodiment, a preformed balloon or composite material can be inserted into the joint site and filled with a flowable biomaterial in situ to conform to the joint site. In yet another embodiment, the preformed component(s) can be fully cured and formed ex vivo and optionally further fitted and secured at the joint site.

  • Publication number: 20070293947
    Abstract: Surgical implants use combined anchoring components to replace meniscal or labral cartilage, in ways that provide strong reinforcement while emulating natural anchoring. An arc-shaped polymer segment is coupled to an anchoring rim made of shape-memory material, which will fit into a groove prepared in a bone surface using specialized tools. A fabric material or anchoring ring is provided above the polymer segment, and can be secured to a knee capsule or other soft tissue. Fabric strips can extend out from the tips of the polymer arc, for additional anchoring. An additional polymer segment can also be provided to replace a hyaline cartilage layer, with a porous bottom surface to promote tissue ingrowth. By using peripheral rather than central anchoring, such implants can be given very high strength and stbility, to last for multiple decades.

  • Patent number: 6896702
    Abstract: A selected augment, shown as a tibial augment, is secured at an augmentation location on a prosthetic implant component, shown as a tibial implant component, by a securing element assembled with the body of the augment for displacement relative to the augment body to selectively engage an abutment located on a depending structure of the implant component, adjacent the augmentation location, so as to establish a securing force between the securing element and the depending structure for urging the augment against the implant component, and thereby secure the augment to the implant component at the augmentation location. In the tibial augment, a distal surface includes surface portions extending in anterior-posterior directions and oriented essentially normal to medial-lateral directions.

  • Publication number: 20040172137
    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: 20040162619
    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 within different portions of the slot. Methods for using the tools and/or implanting the prosthetic devices discussed above are also described.

  • Publication number: 20040059425
    Abstract: Osteochondral repair of damaged articular joint surfaces is achieved using implants in the form of cylindrical osteochondral plugs. The plugs have an articular surface formed on at least one end. If articular surfaces are provided on both ends of the implant, the articular surfaces have differently curved surfaces. The defective cartilage is removed to create a recipient socket for the implant. An implant sized to fit the recipient socket is chosen from a plurality of implants provided to the surgeon. The implants are preferably formed of a hydrogel material such as Salubria™, although metal or allograft implants can also be used.

  • Patent number: 6387131
    Abstract: A knee prosthetic including a tibia part (1), which includes a tibia plate (2) that co-operates with at least one meniscal element by a first side (4), and co-operates with a tibia resection plan by a second side (5), including a tibia pin (3) connected with the tibia plate (2), which penetrates into the tibia to fix the tibia part (1) into it; and at least one compensating tibia block (6), which fits flatly between the second side (5) of the tibia plate (2) and the tibia itself, in order to compensate for a lack or absence of local bone tissue between the tibia and the resection plan. This tibia block (6) also co-operates with said tibia part (1) by way of complementary fixating means (10, 11) that are implemented on the tibia block (6) and tibia part, wherein the complementary fixating means are of the pin (10) and hole (11) type and are implemented on the tibia block and the base (9) of the tibia pin.
