Arthroscopic surgery, also known as arthroscopy, is a surgical procedure to visualize, diagnose, and treat problems inside a joint using a specialized instrument known as an arthroscope.
An arthroscope is a flexible fiberoptic tube that contains a small lens or camera and a lighting system to magnify and illuminate structures inside a joint. The camera attached to the arthroscope shows an image of the joint on a television screen allowing the surgeon to examine the affected joint or areas such as cartilage, ligaments, and tendons, and perform the repair.
