Arthroscopic Anatomic Lateral Ankle Reconstruction Using Allograft: A Simplified Approach

Area of Science:

• Orthopedic Surgery
• Sports Medicine
• Anatomy

Background:

• Ankle instability is a prevalent condition requiring surgical intervention when conservative methods are ineffective.
• Existing surgical techniques for lateral ankle ligament reconstruction vary, with anterior talofibular ligament and calcaneofibular ligament repair/reconstruction being common.
• Restoring ankle joint stability and functional outcomes is crucial for patients with chronic ankle instability.

Purpose of the Study:

• To describe a simplified arthroscopic technique for anatomic lateral ankle ligament reconstruction.
• To detail the use of an extensor hallucis longus allograft in the procedure.
• To outline the percutaneous creation of the calcaneal tunnel based on specific anatomical landmarks.

Main Methods:

• Arthroscopic visualization and instrumentation were employed for the reconstruction.
• An extensor hallucis longus allograft was utilized for ligamentous repair.
• A percutaneous calcaneal tunnel was created after identifying the calcaneofibular ligament's distal footprint relative to the lateral malleolus.

Main Results:

• The described technique offers a simplified approach to anatomic lateral ankle ligament reconstruction.
• The use of an extensor hallucis longus allograft facilitates restoration of ankle stability.
• Percutaneous tunnel creation allows for precise graft fixation.

Conclusions:

• This simplified arthroscopic technique provides an effective method for lateral ankle ligament reconstruction.
• The procedure aims to enhance ankle joint stability and improve functional outcomes in patients with instability.
• Further studies may evaluate the long-term efficacy and patient-reported outcomes of this technique.
