A patient presents to the Emergency Department after sustaining a twisting knee injury while skiing. She felt a pop and was unable to bear weight afterward secondary to pain and a feeling of instability. Shortly after the injury, she noted increased swelling and pain. On examination, she has a moderate effusion and a positive Lachman test. An x-ray was obtained and is shown above (Image 1.
