Fig. 3From: Should sagittal osteotomy line be parallel to tibial posterior slope in high tibial osteotomy?Cross-sectional computed tomography image on the upper osteotomy plane. In the upper osteotomy plane, the midpoint of the line connecting the two points where the hinge line intersects the proximal tibial lateral cortex (hinge position) is displayed on the x-y coordinate system based on the mediolateral and anteroposterior widthBack to article page
