Correction of the Lower Extremity Mechanical Axis Deviation in Children with Angular Deformities of the Knee treated with Guided Growth Hemiepiphysiodesis

Abstract

Background: Correction rate of angular deformities around the knee following hemiepiphysiodesis has been variable in the literature. This study aims to report the rate of mechanical axis after hemiepiphysiodesis around the knee. Factors associated with differences in correction rate are also reported. Methods: Records of skeletally immature patients, who underwent hemiepiphysiodesis for either genu valgum or genu varum between 2004 and 2018, were reviewed. For all patients, temporary hemiepiphysiodesis was performed using tension band plating. Radiographs at preoperative visit as well as each follow up visit were reviewed. Lower extremity mechanical axis deviation …
