Knee Arthroscopy is usually performed under a general or regional anaesthetic.
Once the anesthetic has been administered, the knee is prepared in a sterile fashion and tourniquet is placed around the thigh.
The Arthroscope is introduced through a small incision, about the size of a pen, on the outer side of the knee. A second incision on the inner side of the knee is made to introduce the instruments that allow examination of the joint and treatment of the problem inside the knee joint.
A camera is attached to the arthroscope and the picture is displayed on a TV monitor.
