Background:
The high incidence of ankle sprain within the military sets the stage for prevalent chronic ankle instability. The purpose of this review was to compare and evaluate chronic ankle instability treatment strategies in the military population.
Methods:
Electronic databases were systematically searched in accordance with the Preferred Reporting Items for Systematic Reviews guidelines for English-language, human studies with a military patient population that had been diagnosed with and treated for chronic ankle instability. Exclusion criteria were animal, cadaver, and review studies and case reports.
Results:
Eight studies met the inclusion criteria, representing 695 military service members-625 males (89.9%) and 70 females (10.1%)-and 4 treatment strategies: Broström-related procedures, modified Watson-Jones procedure, Colville's technique, and anatomic lateral ligament reconstruction using semitendinosus tendon allograft. The percentage of satisfactory outcomes was 100% for Colville's technique, and ranged from 73.2% to 94.7% for Broström-related procedures and 72% to 80% for the modified Watson-Jones procedure. Mean American Orthopaedic Foot and Ankle Society scores, anterior drawer displacement, talar tilt, and visual analogue scale scores were also reported.
Conclusion:
This review demonstrates that the Bröstrom procedure has consistently satisfactory outcomes within the military population, and Colville's technique is another promising option for this patient population but would require additional studies to support this claim.
Levels Of Evidence:
Level IV.
