Arthroscopy is usually performed under a general or regional anaesthetic.
Once the anaesthetic has been administered, the ankle is prepared in a sterile fashion and a tourniquet is placed around the thigh.
The arthroscope is introduced through a small (size of a pen) incision on the back of the ankle. A second incision on the front of the ankle is made to introduce the instruments that allow examination of the joint and treatment of the problem inside the ankle joint. After the surgery is complete the incisions are closed and a sterile dressing applied.
