The treatment of a tear of the anterior talofibular ligament can be divided into two ways: conservative treatment and surgical treatment. The choice of treatment is based on the severity of the ligament tear. If the patient has a relatively mild tear of the anterior talofibular ligament, with no destabilization of the ligament, and no subluxation or dislocation of the joint, then conservative treatment with casts or braces can be used. Localized closure and braking with an elastic bandage are also feasible. If the tear of the talofibular ligament is more serious, there is obvious ankle swelling and pain, limitation of movement, and the anterior talofibular ligament that stabilizes the ankle joint is completely ruptured, it needs to be directly sutured by surgical treatment. If there are avulsed bone fragments, they need to be fixed with wires or screws. During the post-treatment rehabilitation of a torn anterior talofibular ligament, the quadriceps muscle needs to be maintained to avoid muscle atrophy. After tearing the anterior talofibular ligament, it is necessary to pay attention to the use of restrictive protective braces for two months; walking with crutches for six weeks to reduce the weight-bearing force of the affected limb; ice packs for 15 to 30 minutes after rehabilitation training to reduce swelling. If you have a tear of the anterior talofibular ligament, you need to consult a doctor in time and under the guidance of a professional physician for treatment and rehabilitation.
