A ruptured ACL in the knee does not necessarily require surgery. When the patient’s knee anterior cruciate ligament area has a serious rupture, it will lead to instability of the knee joint. If the patient does not undergo surgical treatment, it may lead to serious injuries to the joint area in the subsequent exercise process, which will seriously cause the patient to be unable to walk, and the impact on the body is very great. Patients should go to the orthopedic department of the hospital as soon as possible after the corresponding symptoms appear, and can choose conservative treatment or daemon method for treatment in a targeted manner, which can effectively reduce the damage to the knee area and help the ligament area to return to normal. Patients should rest in bed after surgery, and try not to do strenuous exercise to prevent aggravation of symptoms.
