administered a cortisone injection and ordered 6 months of physical therapy. The patient later had an arthroscopy with debridement of the right knee by another physician and completed another course of physical therapy. The patient received minimal relief from these treatments and still is not able to walk longer distances or go on hikes. On examination, he is a healthy appearing male with a body mass index of 24 kg/m2. He has a small effusion, minimal quadriceps atrophy, no tenderness about the knee, full range of motion, stable to varus and valgus stress at 30° of flexion, a grade 1 Lachman test, and a normal posterior drawer. Figures 1 through 4 are his arthroscopic views, radiograph and MRI scan from his prior surgical procedure. What is the next most appropriate step in treatment?
