Ankle lateral ligament complex injury is common. Traditional ‘Brostrum’ repair, performed either open or arthroscopically, still has a protracted post-operative period. The ‘Internal Brace’ provides a scaffold for the ligament repair and acts as a ‘check-rein’ preventing further injury. 16 patients with ankle instability and injury to the Anterior-Talo-Fibular-Ligament (ATFL) confirmed on MRI were identified. All had completed a period of conservative treatment. All had symptoms of pain in the region of the ATFL and described a feeling of instability. Surgery was performed under general anaesthetic and regional popliteal block. Anterior ankle arthroscopy demonstrated a positive ‘drive through’ in all cases. The ATFL was absent and in the majority replaced by incompetent scar. Scar tissue was removed from the anterior aspect of the ankle allowing visualisation of the fibula and lateral talar neck.
