Two groups of children with excessive genu valgum or genu varum were treated with a partial epiphysiodesis. In group I (16 extremities) a predictive chart was used to determine the appropriate bone age to perform the partial epiphysiodesis, and in group II (15 extremities) the age for the procedure was estimated. The partial epiphysiodesis was performed by either an open or a percutaneous technique. In group I the correction of the genu valgum and genu varum followed the predicted course, whereas group II resulted in a 9.1° error. Genu valgum and genu varum in children with adequate remaining growth can be corrected using a predictive growth chart to determine the appropriate bone age for the procedure.
