ABSTRACT:
A grafting technique entailing the transplantation of chondrocytes for promoting the healing of lesions in articular cartilage, use being made for this purpose of in vitro autologous cultured chondrocytes prior to transplantation. The chondrocytes are preferably seeded in a three-dimensional collagen matrix which serves as the graft material. In order to internally fix the graft during the healing process, use is made of a periosteal flap which is sutured to the cartilage after the graft material is implanted therein.
