Abstract

Purpose
This study assessed the clinical outcomes of a modified Broström operation using all-suture anchors for patients with chronic lateral ankle instability.
Methods
A comprehensive analysis was conducted on 22 cases with a minimum follow-up of 1 year. Clinical outcomes were assessed using the Karlsson scores and Sefton’s grading system.
Results
Significant improvement was observed in patients’ symptoms postoperatively. Karlsson scores increased markedly from preoperative levels, indicating substantial clinical improvement. Most patients (20 of 22, 90.9%) were categorized as ‘excellent’ or ‘good’ according to Sefton’s grading. There was no anchor related complication.
Conclusion
The modified Broström operation employing all-suture anchors demonstrated favorable clinical outcomes for patients with chronic lateral ankle instability. This technique can be promising alternative for traditional modified Broström operation, offering improved stability and symptom relief.

Figure

• 

  Fig. 1 (A) A curvilinear incision was made over the distal anterior border of the lateral malleolus. (B) After preparing the bone bed with a Rongeur, two all-suture anchors were inserted at the footprint of the anterior talofibular ligament on the distal tip of the fibula. (C) Subsequently, the joint capsule ligament complex was sutured. Finally, the inferior extensor retinaculum was reinforced by suturing it to lateral malleolar periosteum and the joint capsule.

• 

  Fig. 2 (A, B) During the preoperative evaluation, anterior translation and talar tilt were measured. (C, D) These parameters were subsequently reassessed approximately 8 months postoperatively to evaluate changes following the surgical procedure.
