Ankle sprains are common injuries and typically treated conservatively. Chronic ankle instability, however, can require surgery when nonoperative measures fail. We evaluated the clinical outcomes of an active duty population in a retrospective study of patients who had undergone a modified Broström procedure at our facility from January 2010 through April 2014 by a single surgeon. The electronic medical records and Army E-profile database were reviewed to determine whether the patients had returned to active duty and whether they had any permanent postoperative lower extremity activity restrictions. A total of 127 patients met the inclusion criteria and had undergone the modified Broström procedure during the study period; 34 (26.8%) separated from the military postoperatively. Of these 34 patients, 23 (18.1%) were unfit for reasons related to their ankle and 11 (8.7%) required military separation for reasons unrelated to their ankle. Thus, 93 patients (73.2%) were able to remain on active duty after undergoing the Broström procedure. Of the 93 patients able to remain on active duty, 38 (40.9%) required activity modifications and 55 (59.1%) were able to return to full duty. Chronic ankle instability in active duty patients can be severely limiting. The modified Broström procedure can provide significant improvement in symptoms and allow patients to remain on active duty. In our high-demand population, ˜73% of patients were able to remain on active duty after their injury and subsequent surgery, 60% of whom returned to their previous level of duty without any physical restrictions.
