Knotless Modified Arthroscopic-Broström Technique for Ankle Instability

Abstract

Instability is a common sequela after repeated ankle sprains. When nonoperative treatment fails, open lateral ligament complex repair and reinforcement with the inferior extensor retinaculum has been the gold standard procedure. The recent advancements in arthroscopic techniques have created comparable biomechanical and functional results to open procedures. The authors' modification to the standard arthroscopic technique permits ligament approximation to the distal fibula over a larger surface area, using knotless anchors to avoid the need of an accessory portal and limit potential suture knot-related complications. Level of Evidence: Level V, expert opinion.
