METHOD FOR SURGICAL RECONSTRUCTION OF ANTERIOR CRUCIATE LIGAMENT AND ANTEROLATERAL CAPSULAR-LIGAMENTOUS COMPLEX OF KNEE JOINT Russian patent published in 2020 - IPC A61B17/00 A61B17/56 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to traumatology and orthopedics. Y-shaped combined graft is formed, consisting of two parts: a non-free vascularized tendon of the semitendinous muscle and a free tendon of the gracilis. Non-free vascularized tendon of the semitendinous muscle is folded three times from its free end to level of 3.5–4 cm from the place of its native attachment on the shin bone. Free tendon of the gracilis is passed through the free portion of the produced loop, opposite to the place of attachment of the unfilled transplant on the shin bone. Tibial and femoral bone canals are formed. Transplant is delivered through the tibial canal into the femoral canal through its free portion, the non-free portion of the transplant is placed inside the joint and in the bone canals, and the free ends of the Y-shaped graft from the tendon of the gracilis are brought out through the femoral canal. Intra-articular portion of the transplant is pulled over the free ends and fixed with an interferential screw in the bone canal in the femoral bone with bending the knee joint at a right angle and an average rotated position of the shin. Lateral extraartarticular tenodes is performed with free ends of Y-shaped graft, in tuberculum Gerdy, an inclined tangential canal is formed on an anteriorly external surface of the tibial condyle; the free ends of the Y-shaped transplant are cross-wound under an external lateral ligament and brought into this canal towards each other. In the position of knee joint knee flexion to 165–140 degrees and the middle rotated position of the shin, the free ends of the Y-shaped combined graft are pulled and fixed with knot non-absorbable sutures to each other in form of 8-shaped loop, after that, the non-free portion of the single Y-shaped graft is additionally fixed in the tibial by an interferential screw.

EFFECT: method provides higher reliability of complex knee joint stabilization with reconstruction of an anterior cruciate ligament and an anterior-lateral capsular-ligamentous complex by independent, optimum balance and stability of the joint, stretching parts of a single Y-shaped combined graft from tendons of semitendinous muscle and gracilis.
