title: A former hockey player with knee and calf pain.
abstract: A 37-year-old man presented with severe pain in his left knee and calf. He had no other joint pain, fever, chills, or dysuria. He had previously gone to another hospital, where x-rays of the knees and legs reportedly showed inflammation and arthritis. He had been given oxycodone-acetaminophen, but the pain continued.
