Arthroscopic treatment of instability attributable to capsular injury or laxity.

Among the many causes of shoulder instability are traumatic capsular injury associated with the Bankart lesion and capsular laxity as seen in multidirectional instability. Previously, open surgical procedures were the most commonly accepted surgical treatment of these disorders. However, because of the foresight of surgeons such as Richard Caspari, arthroscopy rapidly is becoming the surgical treatment of choice. Current studies have shown a 97% satisfactory outcome of arthroscopic Bankart repair. Similarly, the arthroscopic treatment of multidirectional instability has produced a 93% satisfactory outcome. These results parallel the gold standard open surgical techniques of the past and subsequently have led to a change in the treatment of shoulder instability.
