Mean values are shown for varus and valgus angles at various postoperative times. The errors bars represent one standard deviation. The varus angle immediately after surgery was greater than at 3, 6, and 12 months postoperatively. We found no difference between 3 months and 6 months, 6 months and 12 months, and 3 months and 12 months in varus or valgus angle.
