What causes an osteochondral defect?
Deep craters involving both the cartilage and the bone may be a result of impact or a condition such as osteochondritis dissecans where blood supply fails to an area of bone, and the bone and cartilage die.
What happens to an OCD without surgical intervention?
The defect is likely to cause pain and altered mobility, but the real issue is that without closing the defect it is likely to extend and lead eventually to arthritis.

Options for cartilage repair of an osteochondral defect
There are a number of possible cartilage repair procedures for attempting to fill the defect back to a congruent cartilage surface.
The big number suggests that none are in fact perfect! Possible interventions include:
