In the present paper we present the biomechanic of the opening osteotomy as a method to correct axial deviations which resulted from usages in the articulation. A parameterized modeling of the surgery is realized, model that allows us, by modifying the parameters, to define the situations that can occur, situations characterized by different: correction angles, positions of the hinge point or the CORA point, positions of the point in which the cutting plane is initiated, diameters of the depressuring hole, the width of the razor used for the surgery, the position of the second cutting plane at the biplane osteotomy. So as these parameters are easy to control(even by persons who are not specialized in assisted modeling) initially it was created a system of points, axes and reference planes that allow to parameterized the model, offering large possibilities of customization of the uniplane opening tibial osteotomy and biplane opening osteotomy.
