case_images: Preoperative standing full leg X-rays demonstrate a severe varus malalignment of 30  right and 17  left (Figures 1(a) and 1(c)). The postoperative X-rays with an almost neutral leg axis (remaining varus of 3  right and 2  left) are shown in Figures 1(b) and 1(d).  Figure 3 shows a close-up of the pre- and postoperative status of the right knee in two planes.
