If anterior tibiofibular ligament and deltoid ligament injuries are not combined with ankle fracture, they can be treated conservatively; if they are combined with fracture, but the stability of the ankle joint is not affected after fracture reset, they can also be treated conservatively; if the joint instability still exists after fracture reset, it should be repaired surgically. 1. Conservative treatment: It is suitable for ligament injury without ankle fracture, or with fracture but good stability of ankle joint after fracture reduction. It can be applied with ice, elevation of the affected limb, local braking and avoiding strenuous exercise. 2. Surgery: If the fracture is combined with the fracture, and the ankle joint is still unstable after the fracture is reset, surgery should be performed to repair the fracture and restore the normal anatomical relationship of the ankle joint, so as to restore the stability of the ankle joint. Periprosthetic ligament injury is a common injury in clinic, once it occurs, it should go to the hospital in time and be diagnosed and treated under the guidance of professional doctors.
