The indications and procedures for arthroscopy of the ankle and subtalar joints continues to increase. Lateral ankle instability is a common pathology that may require surgery to repair injured structures of patients nonresponsive to conservative management. Common surgical methods generally include ankle arthroscopy with subsequent open approach to repair/reconstruct the ankle ligament(s). This article discusses two different approaches to repairing lateral ankle instability through an arthroscopic approach. The arthroscopic modified Brostrom procedure creates a strong repair with minimal soft tissue dissection, and is a reliable, minimally invasive approach to lateral ankle stabilization. The arthroscopic double ligament stabilization procedure creates a robust reconstruction of the anterior talofibular and calcaneal fibular ligaments with minimal soft tissue dissection.
