Anterior shoulder instability commonly occurs in young and active individuals, particularly those participating in contact or collision sports. At the intercollegiate level, rates of anterior instability have been reported to be 0.12 events per 1000 athlete exposures. The treatment of in-season athletes with anterior instability presents a challenge for the team physician. The desire to return to play within the same season with nonoperative management must be weighed against the increased risk of recurrence as well as athlete and team specific demands. The purpose of this chapter is to discuss the key considerations for the management of the athlete with anterior shoulder instability that occurs within the competitive season.
