Abstract: An articular cartilage shell graft is designed to treat the arthritic population for which current biologic treatments are insufficient and as a biological-stage repair for intervention before prosthetic knee arthroplasty.

Abstract: The invention provides an article of manufacture comprising a substantially non-immunogenic xenograft for implantation into humans. The invention also provides methods for preparing a xenograft by removing at least a portion of a soft tissue from a non-human animal to provide a xenograft; washing the xenograft in saline and alcohol; subjecting the xenograft to cellular disruption treatment; treating the xenograft with crosslinking agents, and digesting the xenograft with a proteoglycan-depleting factor and/or glycosidase. The invention further provides a method for sterilizing xenograft material, having the steps of obtaining substantially non-immunogenic xenograft material; treating the xenograft material with at least one crosslinking agent; and subjecting the crosslinked xenograft material to radiation treatment.

Abstract: The invention provides for the use of an improved xenograft bone particulate with respect to osteo-integration and bone remodeling, while diminishing the primate-to-pig immunological response using established bone-processing technique. Work was carried out using undecalcified bone to determine immunocompatibilty and bone remodeling potential of processed porcine bone struts following onlay graft implantation. New bone formation was evident, including the infiltration of cellular materials responsible for fusion and bone reconstruction.

Abstract: Methods and compositions are provided for the treatment of periodontal disease and bone lesions. Preferred methods comprise administering a composition containing one or more osteogenic and/or ligament-inducing bone morphogenetic protein and a suitable carrier. The method results in the regeneration of alveolar bone in both a vertical and horizontal direction, and can result in the regeneration of bone, cementum and ligamentous structure between said regenerated bone and the tooth root surface, such that minimal ankylosis and root resorption results. The method and composition are useful for the repair of supraalveolar periodontal lesions and defects, mandibular and maxillary class II and III furcations and interproximal defects, and augmentation of the alveolar ridge of these structures.

Abstract: A composition comprising a pharmaceutically acceptable admixture of an osteogenic protein; a polymer matrix component selected from the group consisting of poly(lactic acid), poly(glycolic acid), and copolymers of lactic acid and glycolic acid; and an osteogenic protein-sequestering material.
