METHOD FOR CHECK-OUT AND COMPLEX PRIMARY ENDOPROSTHETICS OF KNEE JOINT IN CASE OF DEFECTS OF ARTICULAR SURFACES Russian patent published in 2017 - IPC A61F2/38 A61B17/56 

FIELD: medicine.

SUBSTANCE: invention relates to traumatology and orthopaedics and can be applied for check-out and complex primary endoprosthetics of knee joint in case of defects of articular surfaces. In the process of preoperative planning, radiograms of knee joint are used to determine position and length of supracondylar line of femur in direct projection, by connection of apexes of medial and lateral epicondyles. After that, position of initial line of articular surfaces of femur is determined by connection of medial segment, drawn towards joint space, perpendicular to supracondylar line of femur, from the point of attachment of major adductor muscle of thigh for distance, constituting 0.50 of supracondylar line, and end of lateral segment, drawn towards joint space, perpendicular to supracondylar line of femur, from apex of lateral epicondyle for distance, constituting 0.27 of supracondylar line length. In the process of endoprosthesis implantation its femoral component is placed in femur in such a way that in direct projection line of articular surface of femoral component coincides with initial line of articular surface of femur. Thigh component is fixed in specified position. Implantation of tibial component of endoprosthesis is performed.

EFFECT: method makes it possible to recover normal ligament balance in knee joint.
