Osteochondritis Dissecans

What is it??

Wikipedia defines it as:

“Osteochondritis dissecans (pronounced /ˌɒsti.oʊkɒnˈdraɪtɪs ˈdɪsɨkænz/, and often abbreviated to OCD or OD) is a joint disorder in which cracks form in the articular cartilage and the underlying subchondral bone.[1] OCD is caused by blood deprivation in the subchondral bone. This loss of blood flow causes the subchondral bone to die in a process called avascular necrosis. The bone is then reabsorbed by the body, leaving the articular cartilage it supported prone to damage. The result is fragmentation (dissection) of both cartilage and bone, and the free movement of these osteochondral fragments within the joint space, causing pain and further damage.[2][3][4]”

What is it if you have it?

Pain in your knee that gets worse with standing or walking fairly significant amounts.  Popping and cracking.  Swelling.  Locking.  A “my knee is going to go out” kind of feeling.
