Shoulder arthroscopy is sometimes called “keyhole” surgery or a “shoulder scope” and is one of the most commonly utilized surgical approaches to treat shoulder conditions. Shoulder arthroscopy is a minimally invasive surgical technique that uses a small surgical camera, called an arthroscope. The arthroscope, along with specialized, small surgical instruments are placed inside the shoulder joint using small incisions. The camera projects images to a screen, allowing the doctor to see inside the shoulder joint; surgery is then executed without the need to do a large formal cut or incision (arthrotomy). Dr. Riley J. Williams, Orthopedic shoulder surgeon, has extensive training and experience using shoulder arthroscopy for patients in Manhattan, New York City and the surrounding New York boroughs.
