METHOD OF POSTEROLATERAL STABILIZATION OF KNEE JOINT Russian patent published in 2024 - IPC A61B17/56 A61B1/317 

FIELD: medicine; traumatology; orthopedics.

SUBSTANCE: invention relates to the methods of treating damage to the capsular-ligamentous apparatus of the knee joint, and can be used to treat ruptures of the posterolateral stabilizing complex. The purpose of the proposed method of posterolateral stabilization of the knee joint is to increase safety and effectiveness, as well as technical simplification. The goal is achieved by forming a posterolateral portal 4–5 mm long with one piercing movement of a scalpel in the projection of the attachment of the popliteus tendon to the lateral femoral condyle, posterior to the fibers of the lateral collateral ligament; the scalpel is brought to the capsule covering the tendon of the popliteus muscle without opening the capsule; the scalpel is removed and a punch is inserted and is used as a surgical awl; using the tip of the punch, the deepening of the fossa where the popliteus tendon attaches to the lateral femoral condyle is tactilely found and a hole 4–6 mm deep is made, the punch is removed; an anchor clamp with two pairs of threads fixed in it is inserted and screwed into the hole made; then, with one end of the thread of each pair, the tendon of the damaged popliteus muscle is stitched with an arthroscopic hand beak-shaped instrument; then the popliteus tendon and the lateral capsule are tightened and refixed to the footprint of the lateral femoral condyle, tying the ends of the threads of each pair together, while the knots of the threads, after cutting their ends, are placed deeper than the fibers or the otibial tract.

EFFECT: method provides increased safety and effectiveness, as well as low invasiveness due to the use of only one additional lateral approach and due to the fact that when the structure of the popliteal muscle is refixed and tightened, its function and normal biomechanical role are restored.
