To determine whether the ankle ligaments are strained or ruptured, you can further confirm through the doctor’s examination, together with the MRI or musculoskeletal ultrasonography. 1. Physical examination: when ankle ligament is strained or ruptured, there will be obvious localized swelling, and there will be obvious pain when pressed. If it is a rupture of the ankle ligament, the stability of the ankle joint will be reduced when doing physical examination of the ankle joint. The ankle joint is obviously loose. 2. MRI examination: MRI examination can clearly determine the situation of ligament injury and whether there is ligament rupture. The location of the injury will be obvious in the imaging. 3. Musculoskeletal ultrasonography: musculoskeletal ultrasonography is flexible and convenient, and can be performed at the patient’s bedside, and will have a good display of ligament damage or rupture around the ankle joint. After the ankle sprain, you must go to the regular hospital in time, and under the guidance of the doctor to carry out the appropriate treatment, do not take care of yourself, so as not to delay the condition.
