Rotator cuff surgery is usually performed Arthroscopically. This means that small incisions are made in the shoulder, and a tool approximately the width of a pencil, called an arthroscope, is inserted into one of them. This tool contains a small camera which projects a video onto a screen in the room. The surgeon uses this as a guide, rather than making a large incision and looking directly at the injury or disease. The other tool is similar in width and known as a grasping forceps. It is a combination of a cutting and suction device.
