Abstract
Ankle sprains represent one of the most common injuries sustained by professional and recreational athletes. For those who develop chronic instability requiring surgery, the Broström-Gould procedure has been advocated as the gold standard treatment. Many arthroscopic techniques have been developed in the attempt to replicate this procedure. However, since both calcaneofibular ligament and inferior extensor retinaculum are extra-capsular structures, some of these techniques include a stand-alone repair of the anterior talofibular ligament, while others add a mini-open or a percutaneous modification to perform the Gould augmentation. In our technique, lateral ankle endoscopy provides a clear view and access to these structures, allowing for an all-inside Broström-Gould using three portals. The procedure is safe and reproducible, resulting in a repair that mostly resembles the classical open technique.
