Arthroscopic surgery for the treatment of knee pain is one of the most common orthopedic procedures, despite a lack of relevant scientific studies of its efficacy. One recent, double-blind study randomly assigned patients with knee pain to arthroscopic surgery or sham surgery. One year later, 62 of the 70 patients in the treatment group reported improvement, compared with 63 of the 76 patients in the control group.¹
