A 30 year-old male presents to the emergency department with acute onset of left knee pain.
A 30 year-old male who was otherwise healthy presents with acute onset of left knee pain. The patient reports that he was playing basketball with his brother and he jumped up and felt a pop with sudden pain in the anterior aspect of his left knee. He states that he usually does not play sports, but his brother was in town so they played. He was unable to weight-bear and walk after the injury. He denied previous injuries and surgeries to the left knee. He noted left knee swelling and a feeling that the knee was unstable but denied numbness, tingling, locking, or catching. The patient denied any family history of significant diseases and denied any recent medication, tobacco, alcohol, or drug use.
