The article analyzes literature data (15 Russian and 45 foreign literature sources) on the issue of rehabilitation of patients after anterior cruciate ligament (ACL) arthroscopic reconstruction. The need to develop effective methods for rehabilitation after ACL arthroscopic surgery is due to the need to quickly improve the patient's quality of life and reduce the risk of re-injury and possible complications. The key rehabilitation period after surgery is the first six months. The main goal of rehabilitation measures after ACL arthroscopic reconstruction is to restore healthy biomechanics in the knee joint, eliminate the negative consequences of injury and surgery, and return to the previous activity level. The effectiveness of medical rehabilitation after ACL surgical reconstruction depends on the correct loading at each stage of rehabilitation, as well as on the quality of exercise performance. Each stage requires an individual approach to the patient, an assessment of the restoration of the strength of the injured limb and careful attitude to the quality of the exercises. Different periods of postoperative joint healing, the complexity of assessing the internal state of the joint and the action of mechanical forces inside it, do not allow us to focus only on the terms of rehabilitation protocols and numerical criteria. It is necessary to pay attention to the quality of exercise performance and biomechanics in the process of basic daily activities
