Osteochondritis dissecans is a destructive condition of bone, where blood supply becomes insufficient to a small section of cartilage and its underlying cartilage.
The localised bit of bone may die off and leave a crater, but initially the compromised fragment may not be dead, and it may be possible to fix it back onto the main bone.
Osteonecrosis
If the fragment dies, then the area is managed like a chondral defect. The area is cleaned out and a cartilage repair technique such as ACI or OATS may be employed to repair the area.
