The need for surgical treatment after a ligament tear depends mainly on the specific location and severity of the injury. If the ligament is partially torn, it usually does not affect the stability of the joint, so surgery is not necessary, and conservative treatment can be considered. Patients should not walk with weight during the fixation period, and should take off the cast and then perform functional exercises. At the same time, oral or topical medications can be used to activate blood stasis, reduce swelling and analgesia, and physical therapy can help the ligament function recovery. If the ligaments in the joint are severely ruptured, or even completely ruptured, affecting the stability of the joint, surgical treatment is required, sometimes through minimally invasive arthroscopic surgery to repair. If the ligament is ruptured in another area, an incision of the ligament may be required for repair. Most ligament tears are caused by choosing unsuitable sports when performing physical exercise, such as too much exercise, too frequent exercise, etc. Therefore, patients should be careful to avoid ligament tears caused by inappropriate exercise.
