Stair stepping and swelling of the foot, generally it takes 2-6 weeks to walk, the details are as follows: First, if there is no obvious local ligament tear, only ligament strain or there is soft tissue injury, the patient will have swelling and pain, after resting for two weeks or so, and then fixing the ankle by elastic bandage, the foot function will be fully restored. Secondly, if there are serious ligament injuries, such as partial ligament tears, or even complete tears, the ligaments can be externally immobilized by plaster or surgical ligament reconstruction, to restore the stability of the ankle joints, usually about six weeks, the ligaments will heal completely, and the patient will be able to return to normal walking. Through the above two situations can be analyzed to determine the patient’s recovery time, and at the same time should not forget the rehabilitation training.
