Review Question - QID 211946

A 23-year-old female avid runner with a history of recurrent ankle sprains sustained an acute inversion injury to her right ankle while running 7 weeks ago. At that time, she was able to bear partial weight with crutches. She now returns to the office with complaints of persistent lateral ankle pain and swelling, with the inability to resume running despite the use of an ankle brace and having completed a course of physical therapy. On examination, she has pain with resisted ankle eversion. Weight-bearing radiographs of the ankle are unremarkable. What is the best next step?
