Recovery time from ankle ligament injuries depends on the extent of the injury. The most common ankle ligament injury is ankle sprain, which is the most common trauma in daily life, especially the lateral ligament sprain is the most common, but this kind of injury is rarely paid attention to, serious injury can make the ligament rupture, fracture avulsion. If improperly treated, the joint instability can be left behind, and it is easy to repeatedly sprain. In the long run, joint adhesions or traumatic arthritis may develop, resulting in functional impairment, so its treatment should be as important as fractures. Patients with a sprain of the lateral ligament can be treated with closure if the symptoms are mild, and then braked with an elastic bandage to limit the inward plantar flexion movement of the ankle joint, which can generally be recovered in 2~3 weeks. If the medial deltoid ligament is torn, firstly, the ankle point of the ankle joint needs to be restored by manipulation, and then the movement of the ankle joint can be restricted by using plaster fixation, which can be cured by fixation for 6~8 weeks. If the medial and lateral ligaments are severely damaged, surgical repair will be required, and post-operative review will be required to determine the recovery. Functional exercise should be performed as soon as possible after the pain disappears under the guidance of the doctor.
