Review Question - QID 215743

A 25-year-old male weightlifter presents to your office with anteromedial knee pain, worse with repetitive flexion-extension of the knee. He reports feeling a "popping sensation," along the medial aspect of the knee when he squats. On examination, you note a negative McMurray's test but feel a prominent fold of tissue over the anteromedial knee joint that is painful with flexion and extension of the knee when the tibia is internally rotated. Given these findings, what is the next best step in management of this patient?
