Lateral ankle ligament injuries require different treatments depending on the degree of ligament damage, mainly including braking and resting, and surgical repair. Ligament injuries are minor and have little effect on activity. It is only necessary to brake the ankle joint and apply cold compresses within 72 hours after the injury to help reduce swelling and pain in the ankle joint. Recovery usually occurs with 3 to 6 weeks of rest. If the ligament is mostly torn or partially torn, and it affects the bone and joint movement and the pain is more serious, the ankle can be kept braked and externally immobilized in a plaster cast, and recovery can usually be achieved in 6 to 8 weeks. If the ligament is completely torn or ruptured, early surgical treatment is needed to repair or reconstruct the ligament, and recovery can usually be achieved in 2 to 4 weeks of postoperative cast immobilization. When the lateral ligament of the ankle joint is injured, the relevant examination should be carried out to clarify the degree of injury, and standardized treatment under the guidance of the doctor.
