After the ankle lesion, the patient will be treated with surgery, and most of the patients will have adhesion of the ankle muscles, which will affect the movement of the ankle joints, and they should be instructed by the rehabilitation doctor to carry out early functional exercises for the ankle joints. Specifically, the patient can be instructed to take a standing position, the patient’s affected side of the foot completely on the ground, and encourage the patient to squat down as far as possible to maximize the range of movement of the ankle joint. The above exercises can prevent the ankle muscles from sticking together, and can also maximize the range of motion of the ankle joints, and at the same time can prevent the ankle muscles from atrophy and other conditions.
