Arthroscopy is a surgical procedure used to look inside a joint in the body. Arthroscopy allows a doctor to look at the joint surfaces and the surrounding soft tissues.
During arthroscopy, a thin viewing scope called an arthroscope is inserted into a joint through a small 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 the joint. A sample of joint tissue can be collected during arthroscopy for biopsy. If surgery is done, additional instruments will be inserted into the joint through other small incisions.
