Reason: right knee pain History: pain There is a small (4 to 5 mm) subchondral lucency within the anterior aspect of the medial femoral condyle likely corresponding to a subchondral focus of signal abnormality seen on the prior MRI examination from last year representing either a degenerative cyst or a small posttraumatic osteochondral lesion. The knee otherwise appears normal. We see no joint effusion.
