A 25-year-old man attends his local A&E department. He presents with a painful swollen knee which is unable to bear weight. He gives a history of having sustained an injury while playing rugby for his club. The injury occurred when he was tackled. His foot became stuck in the soft ground and his upper body twisted as he fell to the ground. He describes a popping noise coming from his knee as he fell. He was carried from the pitch and was driven by a friend to his flat. Over the next 2 hours his knee became very swollen and stiff. The pain became worse. At this stage his flatmates drove him to his local hospital.
