To review the biomechanical characteristics of patients after anterior cruciate ligament reconstruction (ACLR), the kinematics, kinetics changes and the functional performances of the knee joint after ACLR are discussed. The changes of the biomechanical characteristics of the patients after ACLR are mainly observed in the sagittal plane, and the alterations of the frontal plane and the transverse plane are observed only accompanying other severe injuries after ACLR. In addition, for the patients after ACLR, one will also observe alterations in the proprioception and neuromuscular control, suggesting that in addition to the routine rehabilitation, the patients after ACLR should also pay extra attention to their proprioception and neuromuscular control training.
