Arthroscopy is a minimally invasive procedure for diagnosing and treating a variety of joint problems. It can be useful for many joints such as the knee, shoulder, hip, elbow, ankle and wrist. An orthopedic surgeon creates a small incision and inserts a very thin instrument called an arthroscope which contains a small camera and lights that allow a better view of the cartilage and ligaments within the joint. This procedure allows the surgeon to diagnose and treat the problem without a large incision. Recovery is typically rapid and most of these procedures are performed on an outpatient basis.
