Following microtrauma to the bone surface, damage to the cartilage and adjacent subchondral bone result in a lucent defect in the surface of the affected bone. Knees and ankles are commonly affected, usually following trauma.
Because these injuries can often be subtle, they are not infrequently missed by A&E doctors. It's a helpful addition to any ankle checklist.
