A 30-year-old man is transported by ambulance to your emergency department from the scene of a motor vehicle collision. He was a restrained driver who lost control of his vehicle and hit the back of a tractor-trailer. His airbag deployed, and he thinks he had a brief loss of consciousness. He complains of pain in his neck, right-side chest wall, and right knee.
He denies any significant medical history and takes no medications regularly. He reports smoking a half-pack of cigarettes per day and consuming alcohol socially; he denies drinking this evening.
Primary survey shows a male in no obvious distress who is currently awake, alert, and oriented. His Glasgow Coma Scale score is 15. Primary exam is stable except for some neck pain and right-side rib pain.
During secondary survey, examination of his right knee shows a superficial laceration with controlled bleeding. No significant swelling is present. The patient does have decreased range of motion secondary to a moderate amount of pain. Distal pulses are present, and there is no neurovascular compromise.
You obtain a portable radiograph of the knee (shown). What is your impression?
