Osteochondritis dissecans - lateral femoral trochlea

Case contributed by Dr Chris O'Donnell


Chronic anterior knee pain with a sensation of clicking

Patient Data

Age: 19
Gender: Male

Large OCD defect with separated osteochondral fragment i.e. cortical bone with low signal intensity and overlying attached articular cartilage.  Note clear fluid signal sitting between the fragment and underlying bone indicating separation. This situation therefore requires attempted repair (reattachment) or excision.

Case Discussion

Large separated osteochondral fragment typical of OCD although location is unusual. The lateral aspect of medial femoral condyle (tibio-femoral articulation) is the most common
