Purpose of review: Ultrasound (US) is an increasingly popular imaging modality currently used both in clinics and operating rooms. The purpose of this review is to appraise literature describing traditional lateral ankle stabilization techniques and discuss potential advantages of US-guided ankle lateral ligament stabilization. In addition, albeit limited, we will describe our experiences in perfecting this technique.
Recent findings: To date, the modified open Broström-Gould technique remains as the gold standard surgical treatment for chronic ankle instability (CAI). In the past decade, modifications of this technique have been done, from a combination of arthroscopic and open procedure to an all-inside arthroscopic technique with a goal of minimizing wound complications, better outcomes, and earlier return to activity. Recently, the use of US as an adjunct to surgical procedures has gained popularity and several novel techniques have been described. The use of US in lateral ankle stabilization could allow accurate placement of the suture anchor at the anatomical attachment of the anterior talofibular ligament (ATFL) without iatrogenic damage to the neurovascular structures such as anterolateral malleolar artery, superficial peroneal nerve, and sural nerve. In summary, the use of US in ankle lateral ligament stabilization is a promising new micro-invasive technique. The theoretical advantages of US-guided ankle lateral ligament stabilization include direct visualization of desired anatomical landmarks and structures which could increase accuracy, decrease iatrogenic neurovascular damage, minimize wound complications, and improve outcomes.
