摘要：
FIELD: medicine.SUBSTANCE: invention refers to medicine, namely to traumatology and orthopaedics in surgical treatment of knee joint injuries. Tear is diagnosed and partial remnants of an anterior cruciate ligament are removed. Four-beam autograft is formed from tendon of semitendinous muscle, wherein distal and proximal circular sutures are formed at distance from ends of autograft. Corrugatory sutures are formed on ends of autograft by transverse suturing of its bundles with subsequent banding. Anterior cruciate ligament is then plicated by pulling the autograft through the tibial and femoral tunnels under the control of arthroscopic technique. Thereafter, at constant traction behind the cortical fixation threads on the tibia, passive flexion cycles are performed and knee joint extension, autograft tension and final placement of femoral fixator and tibial fixator on frontal-inner surface of tibia are performed. Femoral tunnel is formed along the guide pin installed in the area of the stump of the anterior cruciate ligament by means of through drilling of the tunnel with a drill with diameter of 4.5 mm. Then, on the same spoke on the side of the joint, a countersound of the tunnel is made with a diameter corresponding to the diameter of the autograft to depth of 2 cm. Tibial tunnel is then formed with a cannulated drill of the diameter corresponding to the diameter of the autograft on a spoke using a tibial guide with an entry point above the tendon area of the goose-foot along the anterior-inner surface of the shin bone in the upper one-third, and an exit point in the center of the anterior cruciate ligament attachment area on the shin plateau. Between the above circular seams, in the proximal and distal portion of the graft, proximal and distal expansion zones are connected by means of proximal and distal corrugating threads, wherein length of said zones provides increase in their diameter when tightening corrugations of autograft by not less than 20 %.
