Arthroscopy is a surgical procedure orthopaedic surgeons use to visualize, diagnose, and treat problems inside a joint.

An arthroscopy involves the use of a device called an arthroscope to examine the joints. This is a thin, metal tube about the length and width of a drinking straw that contains a light source and a camera. Images are sent from the arthroscope to a video screen or an eyepiece, so the surgeon is able to see inside the joint.
