A graph shows the influence of postoperative FMA on IKS score in patients with substantial varus osteoarthritis (at least 10° varus) preoperatively. We found lower mean scores in patients with valgus alignment of the femoral component compared with those with varus (p < 0.001) and neutral alignment (p = 0.002). No differences in mean scores occurred in patients with varus or neutral component alignment. Values are shown as mean with SD (error bar).
