METHOD FOR ANATOMIC SINGLE-BEAM PLASTY OF ANTERIOR CROSS-SHAPED LIGAMENT BY PATELLAR LIGAMENT TRANSPLANT Russian patent published in 2017 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: "bone-tendon-bone" autotransplant is taken from the patient: a bone block from the middle part of the lower pole of the patella and from the tibia at the site of the patella ligament attachment to the tuberosity of the tibia and the patellar ligament between these bones from the middle third of the patellar ligament. Through transverse apertures are made through each bone block of the autotransplant for filaments for autotransplantation. Channels are made in the tibia and femur. The femoral canal is formed from a point defined as follows: the point of intersection of the lateral intercondylar and lateral bifurcation edges is determined, a retreat is made from this point along the bifurcation margin at a half distance to the articular surface of the condyle and 2 mm posterior and further in a plane parallel to the lateral bifurcation margin by the thickness of the patellar ligament between the bone blocks of the bone-tendon-bone autotransplant. Bone blocks of the autotransplant are sequentially placed in the channels in the tibial and femur bones and fixed to the walls of the channels after connecting ligament tension.

EFFECT: method increases transplant fixation stability.
