Arthroscopic surgery (arthroscopy) is a surgical procedure that allows your doctor to look at the inside of a joint in your body through a thin viewing instrument called an arthroscope. Common sites for the procedure include the shoulder, hip, and knee.

During arthroscopy, the arthroscope is inserted into your joint through a small cut (incision) in the skin. The arthroscope has a light source and a video camera attached to it. Images from the camera can be seen on a video monitor. These magnified images provide a clear picture of your joint. A sample of joint tissue can be collected during arthroscopy for biopsy. If surgery is done, additional instruments will be inserted into your joint through other small incisions.
