For ankle injuries, doctors will usually determine ligament injuries through questioning, physical examination, and imaging tests. 1. Questioning: Ask the patient about the specific circumstances that led to the ankle ligament injury. Generally, repeated wear and tear, such as long-term walking and running, are more likely to lead to ligament injury. 2. Physical examination: patients with ankle ligament injuries will have mild pain symptoms, ankle joint stability is still good, patients may not have obvious subcutaneous bruising, and the degree of swelling is also mild. 3. Imaging examination: through the ankle MRI or color Doppler ultrasonography at the ankle joint, the diagnosis can be clear. On imaging, ligament injuries can be found as continuous ligament signals. If the patient suffers from ankle injury, it is recommended to go to the hospital in time for a clear diagnosis and early formal treatment.
