Hip, Ankle, Elbow Keyhole Surgeries (Arthroscopic) Arthroscopy is a surgical procedure which uses a thin telescope with a light source (an arthroscope) to look inside joints. As well as being able to look inside, the surgeon can use an arthroscope to perform 'keyhole' surgery.Arthroscopy can also be used for other joints, including the shoulder, hip, elbow, wrist and ankle joints, and even for hand or foot problems.
