A 23-year-old man is brought in after being hit by a car. He was in the process of getting into his car when another vehicle coming from the opposite direction swerved into his lane. He tried to jump onto his hood to avoid the other car but was struck by the side mirror and landed on the ground. He is primarily complaining of left knee and lower leg pain.
He denies any medical history. Primary survey appears to be stable except for scalp and facial lacerations. The patient is awake, alert, and oriented, and his vital signs are stable.
His left lower extremity is in a splint immobilizer, placed by emergency medical personnel. There is a moderate amount of soft tissue swelling around the knee, which is exquisitely tender to palpation. The patient has limited flexion and extension of the knee due to pain. He is able to wiggle his toes, and distally in the leg and foot there appears to be no neurovascular compromise.
Radiographs of the tibia are obtained. What is your impression?
