Juvenile osteochondritis dissecans
Updates to Case Attributes
Osteochondral defectOsteochondritis dissecans (OCD) is an acquired condition of the joint that affects the articular surface and osteochondral fragment lying freethe subchondral bone.
The juvenile form of the disease (JOCD) presents occured in those aged five to 16 years with open growth plates.The causes of OCD are unknown; however, repetitive trauma, inflammation, accessory centres of ossification, ischaemia and genetic factors has been proposed.
Knee is the most common lesion site for JOCD and the most prevalent location is within the joint associated with underlying subchondral cystic changeslateral aspect of the medial femoral condyle.
Bilateral radiographic knee evaluation is recommended for all patients found having JOCD, as wellthe incidence of bilateral disease is as focal bone marrow edemahigh as 29%, features are consistent with stage V osteochondritis dissecans (OCD)

There is a large crater (osteochondral defect) seen in the medial femoral condyle filled by joint effusion associated with subchondral cystic changes as well as focal bone marrow edema.
Osteochondral fragment seen in the intercondylar area just anterior to ACL root.
Large amount of joint effusion reaching the suprapatellar bursa.
Features are consistent with Juvenile osteochondritis dissecans (OCD).
