TIBIAL GUIDE FOR DETERMINATION OF CHANNEL CENTER DURING SINGLE-BEAM ANATOMIC PLASTY OF ANTERIOR CROSS-SHAPED LIGAMENT OF KNEE JOINT Russian patent published in 2017 - IPC A61B17/16 

FIELD: medicine.

SUBSTANCE: guide contains a handle 1 and a working part 2, at the end of which a pointed protruding tooth 6 is located and an additional pointed protruding tooth 7 is located at a distance of no more than 13 mm therefrom. After transplant preparation and execution of anterior-external and antero-internal accesses, channels are made in the tibia and femur. To make a channel in the tibia, first, the anatomical center of the attachment zone of the anterior cross-shaped ligament to the tibia is determined corresponding to the center of the channel in the tibia. To do this, the claimed tibial guide is placed in one of the accesses, holding it by the handle, and the guide is fixed by placing the pointed protruding tooth 6 on the posterior margin of the intercondylar elevation of the tibia. Another additional pointed protruding tooth 7 will determine the center of the area of the anterior cross-shaped ligament attachment to the tibia on the tibial plateau.

EFFECT: precise anatomical placement of the transplant and preservation of joint functions.
