Abstract Treatment of clubfoot with the Ponseti method is successful when performed immediately after birth. We treated 23 infants (36 feet) who presented to us after casting, applied at other institutions, failed or after 3 months of age. Twenty-two infants had serial casting started during the first 2 months, and one infant who was 6 months old at presentation had not received previous treatment. The original orthopaedists of 18 patients advised posteromedial release. The parameter studied was the need for posteromedial release (ie, failure of Ponseti casting and percutaneous Achilles tenotomy to obtain satisfactory clinical appearance). Only one (2.8\%) of 36 feet required open surgical release (posterior only). Thirty-five feet required percutaneous Achilles tenotomy. A mean of six Ponseti casts were applied before tenotomy. Two feet (two infants) required anterior tibialis transfer for mild relapse; three other feet (two infants) required repeat casting for mild relapse. Most pediatric orthopaedists think that successful clubfoot casting depends on treatment started immediately after birth. Our data suggest that older infants with clubfoot can be treated successfully without extensive surgery. Our results in older infants are similar to the results of a previous study we conducted with younger infants. In that study, one (2.9\%) of 34 feet required posteromedial release surgery. LEVEL OF EVIDENCE: Therapeutic study, Level IV (Case series). See the Guidelines for Authors for a complete description of levels of evidence.
