| abstract |
The invention is directed toward a cartilage repair assembly (10) comprising a shaped allograft construct comprising a cylindrical mineralized cancellous bone base member (12) and a demineralized cancellous bone cap member (20) having a cylindrical top portion (22) and a stem (26) extending from the top portion (22) mounted to the bone base member (12). The base member (12) has a central bore (14) and a transverse bore (16) which intersects the central bore (14) and the cap member stem (26) has a through-going bore (28) which is aligned with the base member transverse bore (16) when the stem (26) is mounted in the central bore (14) to receive a pin member (30). 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 (20) to generate cartilage growth. |
