Arthroscopy is an important surgical test, which is used to diagnose and treat problems within the joint.  It is mainly used to examine injuries in the knee but techniques have been developed for surgery in other joints, including the shoulder, hip, ankle, wrist and small joints of the fingers.

Arthroscopy is a ‘keyhole’ operation that is used to look inside a joint so that it can be closely examined.

An arthroscope is a narrow tube with a light source attached to a tiny video camera, which transmits pictures back to a TV monitor. The arthroscope is passed through small incisions (cuts) in the skin and lights up and magnifies the damaged area, so the doctor can see everything inside the joint.

Arthroscopy can be used to investigate conditions like arthritis or symptoms such as pain, joint weakness and damage to cartilage and ligaments. There are also small instruments that can be attached to the arthroscope, if needed, to take any biopsy samples or to cut, trim or remove any loose fragments of tissue, bone or cartilage.
