Abstract

An osteochondral graft for use in repairing an articular cartilage defect site includes a cartilage cap and a wall extension. The cartilage cap has a top surface and a bottom surface with the wall extension projecting from the bottom surface. The wall extension includes an external surface and an internal surface with the internal surface defining an internal space. At least one of the internal surface or external surface may be tapered at an angle to facilitate implantation of the graft. The graft may be fabricated from collagen and configured as a composite construct, the cartilage cap being made from a porous collagen material to facilitate cartilage regeneration and the wall extension being made from a substantially cross-linked collagen to provide structural strength to facilitate insertion of the graft into the articular cartilage defect site. A method of repairing an articular cartilage defect with the osteochondral graft is also disclosed.
