Considering the entire series, the results were good in 74.1 per cent., fair in 9.4 per cent., and poor in 16.5 per cent. Eight fair and fourteen poor results were obtained. Of these, sixteen were due to errors in indication, while six were due to errors in technique. It is evident, therefore, that proper selection and surgical technique will produce a stable foot and ankle, which also stabilizes the knee joint. Muscular requisites are good gluteal and hamstring action. Definite contraindications are disalignment of the knee, such as a valgus, hyperextension, or flexion contracture.
