The ankle joint is the main weight-bearing joint of the human body, and it is very easy to sprain or fall during normal sports. Once the injury occurs, swelling, bruising, and restricted movement, it is necessary to go to the hospital for X-ray examination in time. In case of fracture, it is best to go to a foot and ankle specialist for professional treatment. With the continuous in-depth study of ankle injury, we found that the ankle joint is very special and the traditional orthopedic repositioning and fixation often cannot restore the mobility of the ankle joint to the greatest extent, and even the patient receives inappropriate treatment which leads to the bad consequences of injury aggravation or even disability.
