Arthroscopy is a surgical technique in which a camera is inserted into a joint to diagnose and treat problems arising from the joint. It is also called keyhole surgery due to the small size of cuts (called portals) to insert the camera and instruments which allows the surgeon to view the inside of the joint on a screen. This technique can be used in almost all joints, although it is most commonly used in knee and shoulder.

Arthroscopy can be used to diagnose several knee problems, such as a torn meniscus or cruciate ligament tear, or a malaligned patella (kneecap). It is commonly used to reconstruct ligaments in the joint and also repair meniscus. Shoulder arthroscopy can be used to diagnose and treat problems like rotator cuff tear (tendon injury), labrum (lining of shoulder joint) damage or bursitis. It is usually a day case operation with limited risks, and the result is good for most patients. Your recovery time and prognosis will depend on the severity of the problem and the complexity of the required procedure.
