Whether or not a ligament tear requires surgery depends largely on the extent of the ligament tear. If the ligament rupture is relatively minor, only a minor laceration or partial rupture, conservative treatment is feasible to fix the ligament for a period of time to heal. If the ligament is completely torn or mostly torn, then surgery is considered. The treatment plan after a ligament tear is related to the exact extent of the ligament damage. If the ligament is partially torn, conservative treatment can be considered, which mainly consists of cast immobilization and braking for 4-6 weeks, no weight-bearing during the immobilization period, functional exercises after removal of the cast, or oral or topical medications to promote blood circulation, reduce swelling and analgesia, and physical therapy, which can help ligament function recovery. If the ligament in the joint is severely ruptured or even completely ruptured, which affects the stability of the joint, it can be repaired through minimally invasive arthroscopic surgery. If the ligament is ruptured in other areas, an incision of the ligament may be required for repair. Patients must do preparatory activities when exercising ligaments, do not practice too fast or too hard, especially in winter before exercising should move the limbs to avoid muscle and ligament strains or sprains.
