METHOD FOR SURGICAL RECONSTRUCTION OF ANTERIOR-ROTARY DAMAGES CAPSULAR-LIGAMENTOUS APPARATUS OF KNEE JOINT WITH RUPTURE OF ANTERIOR CRUCIATE LIGAMENT Russian patent published in 2020 - IPC A61B17/00 A61B17/56 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, particularly to traumatology and orthopedics. Tibial and femoral bone canal is formed. Anterior cruciate ligament is re-incised with a non-free vascularized transplant. Simultaneously with plasty of an anterior cruciate ligament of the knee joint, lateral extra-articular tenodesis is performed, tendons of semitendinous muscle and gracilis of the shin with length of not less than 26 cm are separated. Common base of the tendons at their fixation point on the tibia is tied with a suture according to the type of a setting unit or is sutured with a ligature. Tendons are laid one on the other and their free ends are sutured together. At a distance from the attachment point on the shin bone, the tendons are sutured together by a ligature suture. Remaining distance is divided into three equal parts and folded to form triplicate, diameter of obtained transplant of anterior cruciate ligament of knee joint is measured. For the lateral extra-articular tenodesis, a non-free graft from the iliotibial tract is taken. External lateral ligament is separated at an attachment point on the lateral condyle of the femur, a tunnel is formed between the ligament and the external epicondyle of the femoral bone, and a transplant is inserted into the tunnel. Bone canals with diameter equal to total thickness of both transplants are formed. Graft from an iliotibial tract is introduced first into a common femoral bone canal, followed by a transplant of tendons of the semitendinous muscle and gracilis. Both grafts are simultaneously stretched and fixed in the femoral canal by the interference screw for both transplants. Non-free part of the graft is additionally fixed in the tibial by an interferential screw.

EFFECT: method enables eliminating instability of the knee joint, providing an anatomically correct recovery of the anterior cruciate and anterolateral ligament with minimizing intraoperative injures, reducing the risk of complications and surgical errors by single-stage conducting, tensioning and fixing of unfree vascularized transplants with a single interferential screw in a common bone canal, made at the point of anatomical attachment of the native anterior cruciate ligament to an external condyle of femur.
