a, bDetermination of the deformity parameters on the AP and lateral view (Ref. [8], with permission). In order to perform correction without fibula osteotomy: origin placed along the mechanical axis of the reference fragment (proximal tibia) at the level of the proximal tibial fibular joint. W distance from the origin to the proximal fibula. Corresponding point: located on the mechanical axis of the distal deformed fragment. To determine the corresponding point distance, T (equal distance to W) should be placed perpendicular to the mechanical axis of the deformed fragment. S axial translation (shortening of the given case)
