Osteotomy configuration of the proximal wedge and analysis of the affecting factors in the medial open-wedge high tibial osteotomy.

Purpose The purposes of this study were (1) to confirm the disparity of the measured thickness at the lateral hinge between anterior–posterior (AP) radiograph and 3D CT image, (2) to evaluate the affecting factors, and (3) to evaluate the differences between uniplanar and biplanar osteotomies.
