The performance of anterior talofibular ligament injury varies according to the degree of injury, and there may be localized swelling, pain and activity limitation. If the injury is mild, edema and pain may occur at the site of the injury due to tissue damage, which can be gradually recovered through rest and braking of the injured ankle. If the injury is severe, hematoma may occur due to damage to small blood vessels, and localized bruising and swelling may require cold compresses within 72 hours, and surgical intervention may be required due to more than one bleeder or rupture of the ligament. Anterior talofibular ligament injuries result in limited mobility as the pain can be exacerbated by movement of the foot. If the anterior talofibular ligament injury does not improve significantly after rest or worsens, it should be consulted in a regular hospital in time, and the doctor will give the correct treatment according to the symptoms, signs and auxiliary examination.
