Man With Sudden Bilateral Leg Pain and Inability to Ambulate

This is the authors' abstract. We don't add key points for this paper.

A 38-year-old man with years of anabolic steroid and testosterone use presented to the emergency department with acute bilateral knee pain and inability to walk. He felt a “pop” and “crunching” sensation in his knees while running to respond to an emergency at work. On examination, he was unable to actively extend the knee and could not bear weight bilaterally. No neurovascular abnormalities were noted. A palpable divot was noted superior to the patella bilaterally. Bedside ultrasound revealed a large hematoma separating the patella from the visualized quadriceps tendon (Figs 1 and 2).
