The recovery time for most ankle sprains is 2-6 weeks. Most ankle sprains are injuries caused by inversion or valgus violence and are not usually associated with fractures or avulsion fractures, but mainly torn or ruptured ankle ligaments, such as the inferior tibiofibular joint ligament, talofibular ligament, and heel-fibular ligament. There may also be tendon damage or joint capsule tears. The patient’s symptoms are mostly swelling, pain, and limitation of motion, and imaging can rule out a fracture. Magnetic resonance imaging reveals intra-articular effusion and abnormal signals of the ligamentous tendons. In patients with severe ankle sprains, early ankle immobilization and braking with ice elevation is recommended to relieve further bleeding and edema, prevent further aggravation of torn ligaments and soft tissues, and promote soft tissue repair. 2 weeks or so, depending on the recovery situation, patients can remove the cast and perform ankle protection and functional exercises to promote local hematoma absorption and relieve joint stiffness and soft tissue adhesions caused by prolonged cast immobilization. In addition, after removal of the cast, the patient can gradually exercise with the help of a walker. Usually, rest should be the main focus, and can be combined with hot compresses, acupuncture, physiotherapy and other auxiliary methods to promote the recovery of injured soft tissues.
