Functional Outcome of Chronic Ankle Instability Treated by Modified Open Brostrom-Gould Procedure

Abstract

Introduction: Ankle sprains remain one of the most commonly reported injuries in athletes. These injuries occur as a result of forced plantar flexion and inversion causing failure of the anterior talofibular ligament followed by the calcaneofibular ligament. Acute ankle sprains are generally treated conservatively. Nevertheless, 20%–40% of patients with an acute ankle sprain might develop chronic ankle instability (CAI). Surgical treatment is advocated for active young patients who develop CAI. MATERIALS AND METHODS: This study is a case series of 10 cases of CAI treated by the modified open Brostrom-Gould procedure from 2014 to 2021. The AOFAS ankle-hindfoot score and visual analog scores were used to evaluate the patient preoperatively and at regular intervals postoperatively. Results: All the patients had good-to-excellent results. There was a significant improvement in the mean AOFAS ankle-hindfoot scores from a preoperative 59.9 to a postoperative value of 91.3. The mean visual analog scores significantly dropped from a preoperative value of 5.9 to a postoperative value of 1.2. The minimum follow-up duration is around 1 year, while the maximum is around 8 years. Conclusion: The open modified Brostrom-Gould lateral ligament repair provides excellent results for chronic lateral ankle instability in active young individuals.
