METHOD OF PLASTY OF MEDIAL FEMORAL-PATELLAR LIGAMENT Russian patent published in 2024 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to traumatology and orthopaedics, and can be used for plasty of medial femoral-patellar ligament. Method involves sampling a graft from a tendinous portion of a gracilis muscle, forming canals in the patella and femoral condyle, holding and fixing the graft in the formed canals. Ends of the graft are sutured with a tendon suture, leaving two free ends of the sutures from each end of the tendon. Two K-wires with an eye are delivered through the patella in parallel in the transverse direction with medial-lateral orientation in the middle of the upper and lower thirds of the patella. Using the cannulated bur, canals are formed on the K-wires from the medial side to a depth of not more than 1/3 of the transverse size of the patella; sutures from each free end of the graft are brought into the wire ears and the suture ends are brought out to the lateral edge of the patella. Smaller-diameter K-wires are inserted in the lateral-medial direction along the previously formed canals. Ends of filaments coming from one canal are charged into an eye of a wire located in another canal, and the suture ends are brought out to the medial edge of the patella; the sutures are pulled up to the stop of the transplant in the ends of the canals formed by the cannulated bur. Knot is formed on the medial edge of the patella using one suture from a pair of sutures coming from different canals; the graft is sutured at the edge of the patella with sutures coming from different canals.

EFFECT: method provides reliability of graft fixation, reduces risk of patella fracture, creates conditions for early start of functional treatment due to peculiarities of graft fixation.
