Although arthroscopic surgery has received a lot of public attention because it is used to treat well-known athletes, it is an extremely valuable tool for all orthopaedic patients and is generally easier on the patient than “open” surgery. Most patients have their arthroscopic surgery as outpatients and are home several hours after the surgery.
Arthroscopy is a minimally invasive surgical procedure on a joint in which an examination and sometimes treatment of damage is performed using an arthroscope, an endoscope that is inserted into the joint through a small incision.
In an arthroscopic examination, an orthopaedic surgeon makes a small incision in the patient’s skin and then inserts pencil-sized instruments that contain a small lens and lighting system to magnify and illuminate the structures inside the joint. Light is transmitted through fiber optics to the end of the arthroscope that is inserted into the joint.
By attaching the arthroscope to a miniature television camera, the surgeon is able to see the interior of the joint through this very small incision rather than a large incision needed for surgery.
Arthroscopic surgery, although much easier in terms of recovery than “open” surgery, still requires the use of anesthetics and special equipment in a hospital operating room or outpatient surgical suite. You will be given a general, spinal, or a local anesthetic, depending on the joint or suspected problem.
A small incision (about the size of a buttonhole) will be made to insert the arthroscope. Several other incisions may be made to see other parts of the joint or insert other instruments.
When indicated, corrective surgery is performed with specially designed instruments that are inserted into the joint through accessory incisions. Initially, arthroscopy was simply a diagnostic tool for planning standard open surgery. With the development of better instrumentation and surgical techniques, many conditions can be treated arthroscopically.
