Osteochondritis dissecans of the knee: a radiology case report.
OBJECTIVE
To discuss the case of a patient with osteochondritis dissecans, a common disorder primarily affecting children and adolescent patients that involves the medial femoral condyle, and to examine its radiologic appearance.


METHODS
A 25-year-old man with knee pain sought treatment at a chiropractic clinic. The patient had a 2-year history of left knee pain that was exacerbated by activity and relieved with rest. Plain film radiography of the knee revealed findings consistent with osteochondritis dessicans.


RESULTS
The patient was promptly referred for a concurrent orthopedic consultation with subsequent management. A trial basis of conservative care was initiated with the possibility of future surgical intervention if necessary.


CONCLUSIONS
Osteochondritis dissecans is a common disorder of unknown and perhaps controversial cause. The disease is characterized by a fragment of articular cartilage and subchondral bone (osteochondral fragment) that becomes separated from the underlying bone. Treatment is aimed primarily at the preservation of articular surface congruity.
