A ruptured ligament is usually treated surgically by re-suturing the ruptured ligament so that the ligament does not become lax after healing and the stability of the joint can be effectively ensured, effectively avoiding degeneration and hyperplasia of the joint. The following steps are usually taken: first, after the anesthesia, cut the skin and subcutaneous tissue to find the ruptured ligaments for suturing, and after the suturing, clean the wound and suture the skin and subcutaneous tissue layer by layer; second, external fixation of the plaster, when fixation, let the sutured ligaments fully in a relaxed state, avoid tension, otherwise it will lead to slow healing of the ligaments and easily lead to ligament relaxation; third, general fixation for about The time, scope and strength of the activity should be gradual, otherwise it will lead to re-injury of the injured ligaments, and it will take about three months to reach full healing, and it is possible to carry out weight-bearing and strenuous exercise.
