Shoulder arthroscopy surgery is performed by making small (1-2 cm) incisions in the front, side, and back of the shoulder, filling the shoulder joint and continuously flushing it with sterile fluid to allow a small camera to be inserted to view the inside of the shoulder. A variety of specialized tools are then placed into the shoulder joint to address any cartilage, muscle, tendon, or ligament injuries. Shoulder arthroscopy is in contrast to open shoulder surgery, where a larger incision is made in the skin and joint capsule (thick fibrous tissue surrounding the joint) in order to access the joint. Smaller incisions and less dissection of the joint capsule allows for quicker recovery and generally less pain after surgery. Today, shoulder arthroscopy has produced equivalent and greater outcomes when compared to open surgery for several shoulder injuries.
