The clinical symptoms of ankle ligament rupture mainly include the following aspects: First, pain at the ankle ligament tear, after the ligament tear, there will be severe and persistent local pain symptoms, local braking or brace fixation, the pain symptoms will be relieved. Secondly, after the ankle ligament is torn, the stability of the ankle joint will be reduced, so the patient will have limited movement of the ankle joint, and the inward and outward turning activity will be obviously limited. Third, swelling, after the ankle ligament is torn, due to the large amount of bleeding at the severed end, it will cause obvious edema in the soft tissue and also affect the blood supply to the severed end of the ligament, which will eventually make the ligament injury unable to repair itself. Combining the above several clinical symptoms, most of them can determine whether there is a ligament rupture or not. The diagnosis can be clarified if the manipulative examination is added during the clinical examination, and MRI can also be chosen as an auxiliary examination.
