A 15-year-old boy presented to the emergency department (ED) with acute onset of right knee pain. While playing basketball, the patient had attempted a layup and had felt a “popping” sensation in midair. He was unable to ambulate after the injury.
At presentation, the patient’s vital signs were normal. His right knee had diffuse swelling, a defect palpable at the site of his tibial tuberosity, and a high-riding patella. Drawer tests and valgus and varus laxity were difficult to assess secondary to pain and swelling. The muscle compartments were soft. The patient was unable to extend his right leg. Popliteal pulses and distal pulses in the foot were normal.
A radiograph of the patient’s knee was obtained (Figure).
