Arthroscopy is a procedure that orthopaedic surgeons use to inspect, diagnose, and treat problems inside a joint.
The word arthroscopy comes from two Greek words, “arthro” (joint) and “skopein” (to look). The term literally means “to look within the joint.” During shoulder arthroscopy, your surgeon inserts a small camera, called an arthroscope, into your shoulder joint. The camera displays pictures on a video monitor, and your surgeon uses these images to guide miniature surgical instruments.
Because the arthroscope and surgical instruments are thin, your surgeon can use very small incisions (cuts), rather than the larger incisions needed for standard, open surgery. This results in less pain for patients and shortens the time it takes to recover and return to favorite activities.
Anatomy
Your shoulder is a complex joint that is capable of more motion than any other joint in your body. It is made up of three bones: your upper arm bone (humerus), your shoulder blade (scapula), and your collarbone (clavicle).
Ball and socket : The head of your upper arm bone fits into a rounded socket in your shoulder blade. This socket is called the glenoid. A slippery tissue called articular cartilage covers the surface of the ball and the socket. It creates a smooth, frictionless surface that helps the bones glide easily across each other.
The glenoid is ringed by strong fibrous cartilage called the labrum. The labrum forms a gasket around the socket, adds stability, and cushions the joint.
Shoulder capsule. The joint is surrounded by bands of tissue called ligaments. They form a capsule that holds the joint together. The undersurface of the capsule is lined by a thin membrane called the synovium. It produces synovial fluid that lubricates the shoulder joint.
When Shoulder Arthroscopy Is Recommended
Your doctor may recommend shoulder arthroscopy if you have a painful condition that does not respond to nonsurgical treatment. Nonsurgical treatment includes rest, physical therapy, and medications or injections that can reduce inflammation and allow injured tissues to heal. Inflammation is one of your body’s normal reactions to injury or disease. In an injured or diseased shoulder joint, inflammation causes swelling, pain, and stiffnes
Injury, overuse, and age-related wear and tear are responsible for most shoulder problems. Shoulder arthroscopy may relieve painful symptoms of many problems that damage the rotator cuff tendons, labrum, articular cartilage, and other soft tissues surrounding the joint.
Common arthroscopic procedures include:
Rotator cuff repair
Removal or repair of the labrum
Repair of ligaments
Removal of inflamed tissue or loose cartilage
Repair for recurrent shoulder dislocation
Less common procedures such as nerve release, fracture repair, and cyst excision can also be performed using an arthroscope. Some surgical procedures, such as shoulder replacement, still require open surgery with more extensive incisions.
