data are expressed as mean ± standard deviation;*significantly different from preoperative data; ** significantly different from postoperative data
Preop preoperative, PO postoperative, FFU final follow-up, CR correction rate, CLS correction loss rate $Correction rate = \begin{matrix} Preop angle - Postop angle \\ - - - - - - - - - - - - - - - \\ Preop angle \end{matrix} \times 100 %; Correction loss = \begin{matrix} Final follow - up angle - Postop angle \\ - - - - - - - - - - - - - - - - - - - - \\ Prop angle \end{matrix} \times 100 %$
