Osteochondritis dissecans (OCD) is a focal lesion of the subchondral bone that can result in fragmentation, instability, and if untreated, loose body formation with progression to early degenerative changes. Particularly in adolescent male athletes, OCD of the knee is a common source of pain, effusion, and mechanical symptoms with sporting activities. Conservative treatment of athletes with OCD of the knee can entail several months of activity modification and non-weight-bearing restrictions, with varying degrees of healing and return to activity.

Osteochondritis dissecans of the capitellum is an overuse injury that occurs primarily in adolescent athletes that causes pain and motion loss and can lead to chronic dysfunction. When diagnosed in its early stages, most lesions can be treated conservatively and without long-term consequences. Many osteochondritis dissecans lesions, however, continue to cause progressive symptoms despite nonoperative measures or are too advanced at the time of initial clinical presentation to be effectively treated without surgical intervention.

Osteochondritis dissecans is a focal lesion of articular cartilage that can result in fragment instability with progression of early osteoarthritis. Regarding the knee joint, salvage of an unstable lesion can be achieved using arthroscopic-assisted reduction and fixation via a 2-stage process. The first involves arthroscopic fixation of the fragment using nonbioabsorbable screws, whereas the second stage performed 12 weeks later involves removal of the screws and confirmation of successful healing of the lesion.

The management of osteochondritis dissecans (OCD) continues to baffle even the savviest of surgeons, with unclear etiology, unknown relationship of presentation to outcome, bewildering response to various treatments, and frustratingly difficult-to-predict prognosis. Whether skeletal immaturity may be indicative of surgical success, at least when it comes to lesions requiring screw fixation, remains debatable. Treatment may include activity modification, drilling, fixation, or osteochondral replacement of OCD lesions in the knee. Read More

Not a Chronic Tennis Elbow Lateral elbow pain is a highly unspecific finding and may be caused by one of several possible differential diagnoses. Unfortunately, it is often assumed to be epicondylitis, commonly referred to as tennis elbow, although instability is a frequent cause in chronic cases. In the presented case, it is the less frequent nerve compression of the radial nerve which must also be considered, together with plica syndrome, osteochondritis dissecans and arthrosis of the radiocapitellar joint, as a differential diagnosis of lateral elbow pain.
