METHOD FOR MINIMALLY INVASIVE KNEE REPLACEMENT Russian patent published in 2014 - IPC A61B17/56 

FIELD: medicine.

SUBSTANCE: minimally invasive approach Quad-Sparing (Q-S) is exercised involving no incision of a quadriceps muscle of thigh of straight and medial portions. The skin is incised for 7-10 cm along an inner surface of the knee joint in a parapatellar direction from an upper pole of the patella to a tibial tuberosity. After the articular surface of the tibia is resected, a resection guide is intramedullary inserted into the tibial canal. A resection unit is fixed on a medial surface of the femur. That is followed by a one-stage resection of the articular surface of the femur in the direction from the medial to lateral condyle. The operation is completed according to the known technique.

EFFECT: by the one-stage bone-saw of the medial and lateral femoral condyles, the method enables reducing the length of the operation and the number of post-operative injuries, and lowering the extend of the intraoperative blood loss.
