Arthroscopy is a surgical procedure in which a surgeon examines the internal structure of a joint using a tube-like viewing instrument. The process of arthroscopic surgery involves inserting a small tube that has optical fibers and a lens through a small incision into the desired joint. Once the arthroscope is inserted, the interior of the joint can be seen on a television monitor in the operating room. After looking around and identifying the injured area the surgeon will create one or more small incisions to insert the tools necessary to perform the repair. A few benefits to having arthroscopic surgery are it causes less trauma to the tissues, the patient often experiences less pain then an open procedure and the recovery period is often faster. Some patients are instructed to begin physical therapy within the first 24 hours of having surgery while others are advised to wait a few more days. Rehabilitation after having arthroscopic surgery will consist of an exercise program that will gradually strengthen the muscles surrounding the affected joint. The main goals of the rehabilitation process after surgery are to recover stability, range of motion, and strengthen the muscles.
