The authors have retracted this article because after publication they discovered that seven patients in their data set had undergone additional procedures. Four of the seven patients underwent valgus correction and three underwent tibial tuberosity transfer. The data from these patients were not included which would have affected the analysis of the results of this study.

All authors agree to this retraction.
