Ligament rupture surgery should be performed as early as possible, because if the ligament rupture surgery is late, the severed end of the ruptured ligament will be atrophied at this time, which will be detrimental to the ligament rupture repair surgery. Ligament rupture surgery includes the following ways: 1. direct suture, which is suitable for the early stage of ligament rupture, there is no defect at the broken end, so that the integrity of the ruptured ligament can be repaired, thus restoring the joint function after healing. 2. bone rivet suture fixation, if the ligament rupture until the point of rupture, then often can not be directly sutured, the ligament needs to be sutured with the help of bone anchor nail, often with very good results. If the ligament rupture is very serious and there is a defect that cannot be sutured in the above two ways, ligament reconstruction is often required.
