Arthroscopy is a surgery done to examine a joint visually. Most of the time, it is done on larger joints, like the knee or shoulder. A special tool called an arthroscope is used. It is an instrument that looks like a long tube with a miniature camera on the end. Repairs or corrections to the joint may be done by using the arthroscope and other tools.

Your doctor will likely do the following to evaluate the joint:

The doctor may use the images to move around other tools that can cut and repair tissue in your joint.
