Volume 85, Number 5 www.aafp.org/afp American Family Physician 509 A 20-year-old man presented to his university’s student health clinic with intermittent pain in his right knee that began two months earlier. He had no history of knee injury or surgery and was otherwise in good health. Physical examination showed a visually normal knee with no effusion. He had normal range of motion but slight tenderness to palpation over the lateral femoral condyle. Testing of the medial and lateral collateral ligaments showed no laxity, and the iliotibial band was not tight. Radiography of the knee was performed (see accompanying figure).
