Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Trial group
The patients who receive arthroscopic surgery.
Arthroscopy surgery
The patient receives intraspinal anesthesia or general anesthesia under supine position. Establish an anteromedial channel at the inner side of the tibial anterior tibial tendon at the level of the tibiotalar joint, and establish an anterolateral channel at the lateral angle of the talus. Exploring and clearing the ankle joint and dealing with possible combined injuries, such as talar cartilage injury, ankle impingement, and loose ankle joints. Then observe the lateral sulcus through the anterior medial channel, clean the synovium in the lateral sulcus, and explore the anterior talofibular ligament. A double-line anchor was inserted into the fibula side stop of the anterior talofibular ligament through the anterolateral channel. The anterior talofibular ligament was sutured using an outside-in technique in the anterior inferior safety zone of the distal end of the fibula. Fix the ankle joint with the suture after the dorsiflexion, neutral valgus position.
Control group
The patients who receive BrostrÖm surgery.
BrostrÖm surgery
The patient receives intraspinal anesthesia or general anesthesia under supine position. The first ankle arthroscopy is performed to deal with possible combined injuries, such as talar cartilage injury, ankle impingement, and loose ankle joints. Then, open surgery was performed, and an arc incision was made at the anterior edge of the lateral malleolus to the tip of the fibula. After separating the subcutaneous tissue, the anterolateral joint capsule and talofibular ligament are exposed. A double-line anchor was placed at the fibular side stop of the anterior talofibular ligament. Tighten and suture the anterior talofibular ligament, anterolateral joint capsule, and extensor support belt with an anchor band. Fix the ankle joint with the suture after the dorsiflexion, neutral valgus position.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. The patient has chronic instability of the lateral ankle joint, including functional instability or mechanical instability; functional instability refers to the patient's subjective ankle joint looseness or instability; mechanical instability refers to the presence of the ankle joint History of repeated sprains, positive examination of the front drawer test or positive X-ray examination of the stress position (inversion stress, anterior axial stress).
3. The ankle MRI suggested the anterior talofibular ligament injury.
4. It is invalid after 3 months of formal conservative treatment.
Exclusion Criteria
2. There was a previous ankle fracture in the affected limb.
3. The affected limb has previously undergone foot and ankle surgery.
4. Ankle inverted arthritis or Charcot joint disease.
5. Suffer from mental illness.
