Q. A 35-year-old female, an avid tennis player, presents to the orthopedic clinic with a 2-week history of persistent right knee pain. She explains that she felt a sharp pain in her knee after a particularly aggressive match where she had to make several abrupt stops and pivots. The pain has been consistent and is exacerbated when she tries to bend her knee or put weight on it. She has tried over-the-counter pain medications and rest, but the pain has not subsided. On physical examination, the knee appears slightly swollen with tenderness on palpation over the medial aspect. She has a restricted range of motion due to pain, especially during flexion. There is no obvious deformity, and the knee is stable on anterior and posterior drawer tests. There is a suspicion of soft tissue injury. Which of the following would be the most appropriate next step in diagnosing her condition?
