摘要：
The invention is directed toward an osteochondral repair assembly comprising a shaped allograft construct comprising an unbalanced barbell-shaped cylindrical cancellous bone primary member formed with a mineralized cylindrical base section having a smaller diameter cylindrical stem leading to a second cylindrical section which is demineralized. A mineralized ring-shaped support member is forced over the compressed demineralized second demineralized the aperture of the ring-shaped member to fit around the stem with one ring surface being adjacent the bottom surface to the second cylindrical section and the opposite ring surface being adjacent the upper surface of the mineralized cylindrical base section.
