Arthroscopy (also known as arthroscopic or keyhole surgery) is a minimally invasive surgical procedure in which an Arthroscope, which is an endoscope inserted into the joint through a small incision, is used to examine, diagnose, and treat joint injury. Arthroscopy is made up of the terms Atheros (joint) and Skopein (to look), and it literally means "to look inside the joint."
Surgeons use a video monitor to examine the joint area and diagnose and repair damaged joint tissue such as ligaments. An arthroscopy examination can be performed on practically any joint, however it is most typically utilised on the knee, shoulder, elbow, wrist, ankle, foot, and hip. The Knee and Shoulder joints are the most often arthroscopied joints. Correcting cartilage and meniscus abnormalities in the knee, as well as repairing rotator cuff injuries in the shoulder, are the most common treatments included.
