Abstract

Introduction: The Ponseti serial casting method is the method of choice in treating children with congenital clubfeet. The arthrogrypotic clubfoot has traditionally been considered challenging to treat, with higher rates of recurrence and the need for more corrective surgeries. However, initial reports have found promising results in using the Ponseti method to treat arthrogrypotic feet. This study aims to compare the outcomes of idiopathic versus arthrogrypotic clubfeet following initial treatment with the Ponseti serial casting method. Methods: A retrospective review of medical records from a single institution was conducted. Data was collected from children ages 0 to 18 with idiopathic or arthrogrypotic clubfoot treated from 2002 to 2022 with Ponseti-style serial casting with a minimum 2-year follow-up. Recurrence was defined as the need for additional casting or subsequent surgeries following initial correction. Data was collected on relevant patient demographics, previous treatment, casting records, Achilles tenotomies, and surgical treatments. Results: A total of 352 patients (546 feet) met inclusion criteria. In all, 334 idiopathic and 18 arthrogrypotic patients were analyzed with an average follow-up duration of 3.4 and 4.2 years, respectively. Twelve patients had distal arthrogryposis, and 6 had amyoplasia. In all, 93.4% of idiopathic and 72.2% of arthrogrypotic patients successfully achieved correction with Ponseti casting and Achilles tenotomy. Recurrence rates were significantly higher in the arthrogrypotic group at 83.3% compared with 44.6% in the idiopathic group (P=0.001). A posterior or posterior medial release was performed in 35.0% of idiopathic and 66.7% arthrogrypotic feet. Conclusions: We report the largest series of arthrogrypotic clubfeet treated by Ponseti casting to the best of our knowledge. In contrast to earlier reports, our investigation underscores that while the Ponseti method may be able to secure initial correction in arthrogrypotic clubfeet, on average, at a 3-year follow-up, the prognosis is less favorable. These patients exhibit higher recurrence and often require operative treatment. Notably, a posterior medial release may eventually be needed in up to 6 of 10 patients. Level of Evidence: Level III—therapeutic studies—investigating the results of treatment.
