METHOD OF MINIMALLY INVASIVE SURGICAL TREATMENT OF CHRONIC POSTEROMEDIAL ROTATORY INSTABILITY OF KNEE JOINT USING ARTHROSCOPIC TECHNIQUES Russian patent published in 2009 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: invention pertains to medicine, namely, to traumatology. Tendons of semitendinous and tender muscles are exposed and sutured proximally. Under arthroscopic control in the middle third of the knee joint soft tissue channel is formed paracapsularly along the eye-pin with a canulled drill, wherein tendons are passed into and delivered through the incision in the region of the adductor tubercle of the medial condyle of femur. Tendons are pulled and sutured in the area, situated above the incision. Horizontal channel is formed in the medial condyle of femur. Sutured part of tendons is fixed with interference screw to the condyle of femur with knee joint bent up to 100° and internal shank rotation, forming anterior portion of collateral tibial ligament. Proximal part of the tendon of tender muscle is passed into the created soft-tissue channel in the top-down direction under the tendon of tailor's muscle, fixed to the medial condyle of themia with interference screw in the strained state with unbent knee joint without rotation of the shank behind the front portion of created ligament. Auxiliary oblique soft-tissue channel is created with a canulled drill along the eye-pin in the top-to-bottom forward-backward direction toward the posterior section of medial condyle of thibia. Proximal section of tendon of the semitendinous muscle is passed into the channel and fixed to the posterior section of medial condyle of thibia with interference screw in the strained state with the knee joint bent at 100° with external rotation of the shank behind created collateral tibial ligament.

EFFECT: method creates oblique femorotibial ligament, eliminates rotatory instability.
