The best recovery time for ankle ligament injuries is 2-4 weeks at the very beginning, and the exact recovery time will be determined by the extent of the ligament injury. Clinical ankle ligament injuries are more common, mostly occurring from inversion sprains of the ankle joint, resulting in ligament injuries in the outer ankle region, mostly to the anterior tibiofibular ligament or talofibular ligament. After the injury, the patient should seek medical treatment promptly to clarify the extent of the ligament injury, which includes local swelling and pain, limited joint movement and difficulty in walking. The swelling can subside and normal walking can be resumed after 2-3 weeks of plaster immobilization. If treatment is delayed, permanent damage to the ligament may occur, and surgery may be required at a later stage. The degree of ankle ligament injury is mainly determined by the mechanism of injury, and the best recovery time depends on the adoption of a standardized treatment plan, so the ankle ligament injury should be treated promptly by a doctor.
