The effectiveness of the Ponseti method for treating clubfoot associated with arthrogryposis: up to 8 years follow-up.

Abstract Purpose To evaluate the effectiveness of the Ponseti method in treating clubfoot associated with arthrogryposis. Methods Retrospective consecutive review over a 10-year period in a tertiary centre of all patients with arthrogrypotic clubfoot treated with the Ponseti method. The primary outcome measure at final follow-up was the functional correction of the deformity. Results There were ten children with 17 arthrogrypotic clubfeet, with an average follow-up of 5.8 years (range 3–8 years). The average age at presentation was 5 weeks (range 2–20 weeks). Deformities were severe, with an average Pirani score of 5.5 (range 3–6). Initial correction was achieved in all children with an average of 8 (range 4–10) Ponseti casts and a tendo-Achilles tenotomy (TAT) was performed in 94.1 %. Two-thirds of patients had a satisfactory outcome at final follow-up, with functional plantigrade, pain-free feet. Conclusions The Ponseti method is an effective first-line treatment for arthrogrypotic clubfeet to achieve f...
