This matched cohort study compared 34 clubfeet treated with the Ponseti technique against 34 historically matched feet treated with traditional serial casting. The primary outcome was need for posteromedial release (PMR) within the first year of life. It was the first controlled institutional comparison providing evidence to validate Ponseti's published claims.
Before this paper, most centers treated clubfoot with 3–5 months of serial casting followed by PMR when correction was incomplete — which happened in up to 94% of cases. The long-term cost of that surgery (dorsiflexion averaging only 8°, progressive stiffness, pain by the second decade) was accepted as unavoidable.
This study showed that Ponseti technique, applied faithfully, makes PMR unnecessary in over 95% of cases. The key decision rule: if a foot has residual equinus after the forefoot reaches 60° abduction, perform percutaneous Achilles tenotomy. A quick office procedure. Rather than open release.
When you see a family struggling with bracing compliance, treat it as a surgical urgency. The one failure in this series happened because parents stopped using the orthosis after a corrected foot. Recurrence from noncompliance still ends in PMR.
This paper, alongside Cooper and Dietz's 30-year follow-up of Ponseti's own patients (78% excellent/good outcomes), gave the field the comparative data to make Ponseti casting the global standard of care.
