Osteochondral Injuries

 

 

        

   

Traditionally, OCDs have been thought to occur as a result of repetitive trauma within the joint. However, more recent studies suggest the possibility of metabolic or genetic causes, which may alter the architecture or composition of the bone.

In OCDs of traumatic origin, such as in patients with a history of injury or recurrent trauma, both the cartilage and the bone are usually affected. These types of injuries may cause a shearing of the cartilage or a focal bone and cartilage injury with a saucer-shaped defect.

In those defects without a history of trauma, in which a new bone injury occurs, the bone scaffold is lost and a cystic lesion forms within the bone, which, as it progresses, may cause the overlying cartilage to collapse into the defect.
