You are evaluating a multiple trauma patient who sustained a substantial head injury, was intubated and is non-communicado. On the secondary survey you note some left knee swelling. The extremity is neuro-vascularly intact, and the knee is stable to stress testing. There is an effusion present. Due to the head injury, you are transferring the patient to the referral center.
Initial portable X-ray of the knee is shown. As fate would have it, the hour is late and the radiologist is at home, all tucked-in and snug in her bed. You would like to give an accurate report to the receiving physician.
Do you see a fracture in the knee joint?
