Review Question - QID 5610

A 45-year-old male is referred to you for management one day after an open Achilles tendon rupture. He suffered a forced dorsiflexion injury while landing a jump on his motorcycle. He presented to the emergency department with a clean, 3cm transverse wound over the Achilles tendon just proximal to the insertion. He was taken for urgent debridement that day by the on-call Orthopaedic surgeon. The surgeon could not re-approximate the Achilles tendon and noted a 2 to 3 cm defect with the tendon avulsed off of the calcaneal insertion. The surgeon debrided and primarily closed the wound without repairing the tendon. He then contacted you to assume the patient's care. The patient states he had multiple corticosteroid injections prior to his injury for pain and swelling at the Achilles insertion. Figure A is a radiograph taken prior to his injury. Which of the following is the best option for treatment?
