  • Publication number: 20210322173
    Abstract: A shaped cartilage matrix isolated from a human or animal where the cartilage has been crafted to facilitate disinfection, cleaning, devitalization, recellularization, and/or integration after implantation. Also, a process for repairing a cartilage defect with the cartilage matrix. The matrix is in the form of an osteochondral plug including a cartilage cap ad subchondral bone, wherein one or more gaps, slats, bores, or channels extend through the tidemark at the interface between the cartilage cap and the subchondral bone.

  • Patent number: 9125743
    Abstract: The present invention is directed toward recellularizing a devitalized cartilage graft with viable recellularizable cells in vivo, in situ, or in vitro to render the tissue vital. The present invention is also directed toward repairing a cartilage defect and implanting a cartilage graft into a human or animal by crafting a cartilage matrix into individual grafts, disinfecting and cleaning the cartilage graft, applying a pretreatment solution to the cartilage graft, removing cellular debris using an extracting solution to produce a devitalized cartilage graft, recellularizing the devitalized cartilage graft, implanting the cartilage graft into the cartilage defect with or without an insertion device, and sealing the implanted cartilage graft with recipient tissue. The devitalized cartilage graft is optionally stored between the removing cellular debris and the recellularizing steps.
