  • Patent number: 7842669
    Abstract: Methods and compositions are provided for the treatment of articular cartilage defects and disease involving the combination of tissue, such as osteochondral grafts, with active growth factor. The active growth factor is preferably a composition containing at least one bone morphogenetic protein and a suitable carrier. The method results in the regeneration and/or functional repair of articular cartilage tissue.

  • Patent number: 7648524
    Abstract: An anchor for fixing a ligament or tendon replacement in a bore formed in a bone has two parts. A first partially cylindrical part has a semi-circular bore therethrough extending along an axis. The bore tapers conically inwardly with respect to the axis from a larger radius at a first end to a smaller radius at second end. The outer surface of the partially cylindrical part is spaced at a constant radius from the axis between the first and second ends. The first and second parts have side walls formed between the bore and the outer surface which walls extend along a plane which forms an angle with respect to the central axis. When the two parts are engaged along their side wails and slide with respect to the axis the outer diameter of the two parts enlarges.

  • Publication number: 20040131754
    Abstract: A process for applying a coating having a therapeutic agent such as an antibiotic or a bone morphogenic protein such as OP-1 protein to an implant uses the high surface area of a calcium phosphate coated metal implant as a repository for the therapeutic agent. The implant is coated with one or more layers of calcium phosphate minerals such as hydroxyapatite. After the crystalline layer is applied, which is usually done within an aqueous solution, the implant is dried and packaged. Immediately prior to implantation, the implant is removed from the package and the crystalline layer of calcium phosphate is wetted with an aqueous solution containing the therapeutic agent.
