摘要：
A composite for osteochondral defect repair includes a porous scaffold and a periosteal graft secured to a surface of the scaffold. The composite provides cartilage growth from autologous periosteum chondrogenesis. Biological resurfacing of large osteochondral defects, or a complete joint is feasible using the porous scaffold/autologous periosteal composite. The use of this composite eliminates the necessity of using normal cartilage surface as a donor site and its respective associated morbidity. In one form, the strong bone integration capacity of a porous metal (e.g., tantalum) scaffold and the high grade of integration observed from periosteal chondrogenesis into the normal cartilage eliminates the lack of chondral-chondral integration observed in the autologous osteochondral graft technique.
