Research methodology: Design for the reconstruction of the ACL using a collagen membrane: The design involves the study of the medical device in experimental treatment groups in comparison with the control group. The study group will initially include 5 patients. As a reference group, the results of treatment of 5 patients with ACL reconstruction by autograft. Design for the collagen spacer of the first toe: The study group will initially include 5 patients. Description of the work stages: For ACL reconstruction using a collagen membrane: Screening: * Procedure for obtaining informed consent; * Collection of demographic data, medical history; registration of previous surgical interventions on the knee joint; * Assessment of vital signs (blood pressure, heart rate, respiratory rate, t°); * Measurement of height, body weight, body mass index (BMI) (growth is estimated once per study - at screening); * Physical examination; * Evaluation of MRI of the knee joint (ACLOAS); * Registration of the previous/concomitant therapy; * Registration of pain therapy; * Assessment of compliance with the inclusion/non-inclusion criteria; For patients who meet the preliminary inclusion criteria and do not meet any of the criteria for non-inclusion in the screening, the date and time of arthroscopy will be assigned. The researcher gives the patient: * Patient information sheet and informed consent form; * Patient's card; * Rehabilitation program.
