Although the shoulder is a complex joint, our understanding of shoulder injuries and pathology has improved greatly in the past decade. As the diagnosis of shoulder problems has become more accurate and specific, the success of treatment has increased as well. At the same time, arthroscopic minimally invasive surgical techniques for the shoulder have shown tremendous advancements and provide the patient with shoulder pain and dysfunction effective treatment options. Arthroscopic surgery employs the use of a camera attached to a long lens, which is inserted into the shoulder through tiny incisions. Through other small incisions, tools can be introduced to repair, or restore damaged tissues. Less insult to normal tissues often leads to a better and faster recovery.
