摘要： The invention is directed toward a cartilage repair assembly comprising a shaped allograft two piece construct with a demineralized cancellous cap and a mineralized cylindrical base member defining a blind bore with a through going transverse bore intersecting the blind bore. The demineralized cancellous cap has a cylindrical top portion and a smaller diameter cylindrical stem extending away from the top portion which fits into the blind bore of the mineralized base member. The cap stem defines a transverse through going bore which is aligned with the through going bore of the base member to receive a cylindrical cortical pin holding the cap within the base member. The shaped structure is dimensioned to fit in a drilled bore in a cartilage defect area so that the assembly engages the side wall of the drilled bore in an interference fit.

摘要： Mixtures, such as gels or pastes, comprising freeze-milled cartilage particles and exogenous growth factors are used for repairing chondral defects. Such mixtures may be applied to constructs comprising cancellous bone for implantation at the defect site. Suitable growth factors include variants of FGF-2, particularly variants that include a sole amino acid substitution for asparagine at amino acid 111 of the β8-β9 loop of the FGF-2 peptide. Such FGF-2 variants are released slowly and continuously at a constant rate from cartilage pastes. In other embodiments, the amino acid substituted for asparigine is glycine. Other variants that may be used include FGF-9 variants having truncated chains and a sole amino acid substitution in the β8-β9 loop of the FGF-9 peptide either for tryptophan at amino acid 144 or for asparagine at amino acid 143.

摘要： Constructs that are at least partially constructed of allograft cancellous bone are disclosed, along with cartilage particles that may be used with the constructs for repairing articular cartilage defects. A multi-piece construct includes a base member, a cap member and at least one pin that secures the cap member to the base member. The base member may be constructed of mineralized cancellous bone, and is used to replace the subchondral bone removed when a surgeon cuts a bore in the area of an adjacent cartilage defect. The base member includes a blind bore and first and second through-going transverse bores in opposite sides of a wall of the base member. The cap member includes an upper section that has a thickness that is similar to that of a patient's surrounding articular cartilage layer and a stem depending from the upper section that is dimensioned to be received in and by the blind bore of the base member. The stem includes a transverse through-going bore, which may be aligned with the transverse through-going bores of the base member to receive the pin therein when the construct has been assembled. The cap member is at least partially formed of demineralized allograft cancellous bone, into which a mixture containing lyophilized, freeze-milled allograft cartilage particles may be infused for the repair of articular cartilage defects. The cartilage particles have a size within a range of from about 10 microns to about 210 microns.

摘要： The invention is directed toward a cartilage repair assembly comprising a shaped allograft construct comprising a cylindrical mineralized cancellous bone base member and a demineralized cancellous bone cap member having a cylindrical top portion and a stem extending from the top portion mounted to the bone base member. The base member has a central bore and a transverse bore which intersect the central bore and the cap member stem has a through going bore which is aligned with the base member transverse bore when the stem is mounted in the central bore to receive a pin member. Milled cartilage particles having a size ranging from 10 to 212 microns are mixed with a biocompatible carrier and a cartilage growth factor, with the mixture being infused in the cap member to generate cartilage growth.
