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. |
