![]() Since the ligature is not absorbable, rejection reaction, wound infection, and pain may occur after surgery. However, at present, repair of the ATFL stump with a suture anchor under total arthroscopy uses knot pulling fixation, which is prone to irritation of surrounding soft tissue or knot release. With the continuous development of minimally invasive techniques, the treatment of CLAI under total arthroscopy has been favored by most scholars. Anatomical suture repair of ligaments is advocated for some patients with severe injuries, open lateral ligament reconstruction is recommended, using autologous or allogeneic tendons for anatomical reconstruction of the anterior talofibular ligament and calcaneofibular ligament. For CLAI patients with a short course of disease and mild injury, ligament continuity still exists. Surgery can restore ankle stability and function. When conservative treatment fails, articular cartilage damage due to articular kinematic changes can occur. The main manifestations of CLAI are frequent fear of walking at night, persistent ankle swelling and pain, relaxation or stiffness, and chronic lateral ankle instability caused by decreased function. Chronic lateral ankle instability (CLAI) symptoms occur in up to 40% of patients with ankle sprains. Ankle sport injuries account for 10–15% of all sports injuries, often leading to injury or even rupture of the anterior talofibular ligament (ATFL).
