After 2 weeks of the above treatment, if the pain and swelling are significantly relieved, you can remove the expenses or bandages and resume weight-bearing walking on the ground. If the pain and swelling do not subside significantly in about 2 weeks, suggesting that the degree of ligament tear is more serious, you can continue to extend the braking and fixation time, and resume walking after 1-2 weeks, or go to the hospital to find an orthopedic surgeon for further examination.
