Arthroscopy

Arthroscopy, technique used to visualize the interior of a joint. Using a fiber-optic endoscope (arthroscope) inserted into the joint through a small incision, a doctor can perform a thorough examination and certain surgical operations. Arthroscopy is most commonly used to treat torn cartilage in the knee, although arthroscopic procedures of the shoulder, elbow, and hip are also common. The low morbidity associated with this procedure makes it useful in a variety of joint disorders as an adjunct to diagnosis, to determine prognosis, and as a treatment.
