Minimally invasive reconstruction of the lateral ankle ligament using tendon allografts to treat chronic ankle latetral instability
Background: Ankle sprain is the most common injury and further improvement in understanding of this injury is still needed.
Methods: During the period from August 2010 until July 2013, 23 patients with chronic post-injury ankle instability underwent minimally invasive surgical ligament reconstruction. All of the 23 patients underwent follow-up examination. The follow-up periods ranged from 8 to 26 months, with a mean of 12 months.
Results: Eighteen patients were post-operatively scored as excellent, 3 as fair, and 2 as pass; therefore, the excellent/fair rate was 91.3%. The mean pre-operative AOFAS score was 70 (range, 65–75); whereas the mean post-operative score was 95 (range, 90–98).
Conclusion: Minimally invasive reconstruction of the lateral ankle ligament using tendon allografts is suitable for use in patients with chronic ankle instability due to lateral ankle ligament injury.
