During arthroscopy, an orthopedic surgeon makes two or three incisions in the treatment area. The surgeon inserts the arthroscope and any other necessary instruments into the small incisions. Images are sent from the arthroscope to a monitor, so the surgeon can examine joints, cartilage, muscles, ligaments, and tendons. The images are used to diagnose or surgically treat the problem. The arthroscope is removed, and the incision is closed with stitches or staples and a bandage.
