Arthroscopy

Inspection through an endoscope (viewing tube) of the interior of a joint. Arthroscopy is most often used to diagnose disorders of the knee joint but can also be used in other joints such as the shoulder, hip, or wrist. It allows the surgeon to see the surface of the bones, the ligaments, the cartilages, and the synovial membrane. Specimens can be taken for examination. Some surgical procedures, such as removal of damaged cartilage, repair of ligaments, and shaving of the patella (kneecap), are usually performed arthroscopically.
