Statistical evaluation of the 2D accuracy of the mechanical leg axis (HKA) correction, measured as the mean difference of HKA between planned and achieved correction, and the average accuracy of maintaining posterior tibial slope (PTS). For graphical visualization, boxplots were used, with the ends of the whiskers indicating 1.5 times the interquartile range (IQR) between the lower and upper quartiles, and outliers denoted with a circle
