Knotless Modified Arthroscopic-Broström Technique for Ankle Instability.

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Anatomy

Background:

• Chronic ankle instability frequently follows recurrent ankle sprains.
• Surgical repair of the lateral ligament complex, augmented by the inferior extensor retinaculum, is a standard treatment when conservative methods fail.
• Arthroscopic techniques now offer outcomes comparable to open procedures.

Purpose of the Study:

• To describe a modified arthroscopic technique for lateral ankle ligament reconstruction.
• To enhance ligamentous repair by increasing the surface area of approximation to the distal fibula.
• To minimize complications associated with traditional arthroscopic methods.

Main Methods:

• Arthroscopic visualization and repair of the lateral ankle ligament complex.
• Modification involves securing the ligaments to the distal fibula over a broader area.
• Utilizes knotless anchors to eliminate the need for an accessory portal and associated knot-related issues.

Main Results:

• The modified technique allows for greater ligament contact with the distal fibula.
• Knotless anchors simplify the procedure and reduce the risk of knot-related complications.
• This approach aims to provide robust and durable ankle stabilization.

Conclusions:

• The described modification to arthroscopic ankle stabilization offers a potentially safer and more effective alternative.
• It facilitates improved ligamentous healing and stability by maximizing the repair surface.
• This technique may become a valuable option for managing chronic ankle instability.
