Ankle sprains are common musculoskeletal injuries, with approximately 27,000 occurring every day in the U.S. alone. The anterior talofibular ligament (ATFL) is the most commonly injured ligament. Although most acute lateral ankle sprains can be treated conservatively, up to 20% of these injuries result in chronic lateral ankle instability and may require surgical stabilization. Recently, an arthroscopic lateral ankle ligament repair technique has become increasingly popular. This minimally invasive procedure is expected to reduce postoperative pain and promote faster recovery. The current article presents an ATFL repair using a 2-portal, non-distraction arthroscopic technique. Chronic lateral ankle instability refractory to physical therapy for 3 to 6 months is the main indication for surgical treatment, and sufficient quality of ligament tissue remnant is required for arthroscopic repair. Compared with an open procedure, equivalent clinical results and earlier recovery following arthroscopic ATFL repair have been reported. The major steps of the procedure, demonstrated in this video article, are (1) placement of portals for the arthroscopic procedure, (2) suture anchor insertion into the distal aspect of the fibula, (3) needle insertion into the ATFL remnant, (4) a lasso-loop stitch using a suture relay technique, (5) reattachment of the ATFL remnant, and (6) postoperative protocol. Complications are rare, and earlier return to daily activities compared with a standard open technique can be achieved.
