[Chronic lateral ankle instability. Modified technique]

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Ankle Reconstruction

Background:

• Chronic ankle instability involves recurrent ankle sprains, impacting function.
• It can manifest as either functional or mechanical instability.
• Surgical intervention is often considered for persistent cases.

Purpose of the Study:

• To evaluate the efficacy of the modified Broström-Gould technique with anchors for chronic lateral ankle instability.
• To assess patient outcomes using the American Orthopaedic Foot and Ankle Society (AOFAS) scale and radiographic analysis.
• To analyze data from patients treated between 2008 and 2016.

Main Methods:

• A prospective, descriptive, cross-sectional study design was employed.
• The study included patients diagnosed with chronic lateral ankle instability.
• Treatment involved the Broström-Gould procedure augmented with suture anchors.

Main Results:

• The study followed 13 patients (1 male, 12 female) with an average age of 38 years.
• The modified Broström-Gould technique showed a significant improvement in AOFAS scores from pre-surgery (average not specified) to 6 months post-surgery (73.4 ± 18).
• Left ankle (54%) involvement was slightly more common than right ankle (46%).

Conclusions:

• The modified Broström-Gould technique, when combined with anchors, provides a straightforward and effective surgical option.
• This method facilitates the repair or replacement of key ankle ligaments, including the anterior peroneal and peroneocalcaneal fibular ligaments.
• It represents a valuable alternative for managing chronic lateral ankle instability.
