Whether knee ligament injury can be cured depends on the degree of knee injury, if the degree of knee ligament injury is relatively small, it can be cured by itself, if the knee ligament injury is torn and damaged, it cannot be cured by itself. For patients with minor knee ligament damage, if only a small tear of the knee ligament remains continuous through MRI observation, this situation can be self-healing, but you need to cooperate with some acupuncture, physical therapy and other means of treatment. If the knee joint ligament is completely torn, the human autologous repair can not reconnect the torn ligament, so it can not be self-healing, generally can be treated by surgery, suture the torn ligament, and then external immobilization, it can be effectively treated.
