A rupture of the anterior cruciate ligament of the knee requires surgery. A rupture of the anterior cruciate ligament of the knee will lead to joint instability of the knee, especially when the knee is in motion, there is no way to stop the relative movement of the tibial plateau and the distal femur of the knee, which causes the distal femur to move forward during the movement, thus causing serious injury to the joint. In addition, it may cause damage to the nerves and blood vessels of the joint. Therefore, it is important to have arthroscopic ligament reconstruction surgery after ACL rupture, as ligament reconstruction can better maintain the stability of the knee joint and prevent more serious damage to the knee joint.
