Treatment of idiopathic clubfoot using the Ponseti method: minimum 2-year follow-up

Abstract

One hundred and thirty-seven idiopathic clubfeet were treated by the Ponseti technique and followed for at least 2 years. Nine feet (7%) were not corrected with initial casting and required early surgery. Recurrence after correction was related to compliance with bracing. At latest follow-up, two-thirds of those noncompliant with brace had recurrences with one-third of these recurrences requiring more extensive surgery than Achilles tenotomy and anterior tibial tendon transfer while only 14% of those compliant with brace had recurrences with none requiring more than Achilles tenotomy and anterior tibial tendon transfer. Early failures and recurrences constituted about 20% of our 137 feet by 2 years of follow-up. When the Ponseti method was fully followed, including initial casting, compliance with brace and treatment of recurrences by recasting, Achilles tenotomy and/or anterior tibial tendon transfer, our success rate was 93%.
