ACL tears have the potential to heal on their own. If the ligament is slightly torn, the tear surface is not large, and the ligament is not ruptured, timely joint braking and immobilization measures, such as immobilization with bandages, splints, braces, or casts, etc., it is possible that the ligament will gradually heal on its own. If the anterior cruciate ligament injury is serious, the tear surface is relatively large or the ligament is torn, which affects the stability of the joint, surgery should be considered for ligament reconstruction, such as arthroscopic minimally invasive surgery, joint replacement surgery, and so on. Whether or not an ACL tear can heal on its own depends on the severity of the ACL injury. It is recommended that patients go to the orthopedic department of regular hospitals to improve the relevant examinations, such as X-ray film, magnetic resonance imaging, etc., with the professional doctor’s examination and analysis and treatment recommendations, to choose the appropriate treatment plan.
