Abstract

Purpose

The Ponseti method has revolutionized the clubfoot treatment and has been adopted globally in the past couple of decades. However, most reported results of the Ponseti method are either short or midterm. Studies reporting long-term outcomes of the Ponseti method are limited. The following systematic review aimed to provide a comprehensive overview of the published articles on long-term outcomes of the Ponseti method.

Material and methods

A literature search was performed for articles published in electronic database PubMed (includes Medline) and Cochrane for broad keywords: “Clubfoot”; “Ponseti method/technique”; “long term outcomes/results.” Studies selected included full-text articles in English language on children less than one year with primary idiopathic clubfoot treated by the Ponseti method with mean ten year follow-up. Non-idiopathic causes or syndromic clubfoot and case reports/review articles/meta-analyses were excluded. The following parameters were included for analysis: number of patients/clubfeet, male/female, mean age at treatment, mean/range of follow-up, relapses, additional surgery, range of motion, various outcome scores, and radiological variables.

Results

Fourteen studies with 774 patients/1122 feet were included. The male:female ratio was 2.4:1. Mean follow-up recorded in studies was 14.5 years. Relapses occurred in 47% patients with additional surgery being required in 79% patients with relapses. Of these, 86% of surgery were extra-articular while 14% were intra-articular. Plantigrade foot was achieved in majority patients with mean ankle dorsiflexion of 11 degrees. The outcome scores were in general good in contrast to radiological angles which were mostly outside normal range with talar flattening/navicular wedging/degenerative osteoarthritis changes occurring in 60%, 76%, and 30%, respectively.

Conclusions

Long-term follow-up of infants with primary idiopathic clubfeet treated by the Ponseti method revealed relatively high relapse and additional surgery rates. Radiologically, the various angles were inconsistent compared to normal ranges and anatomical deformations/degenerative changes were present in treated feet. Moreover, the relapse rates and requirement of additional surgery increased on long-term follow-up. Despite this, majority feet were plantigrade and demonstrated good clinical results as measured by various outcome tools. There should be emphasis on long-term follow-up of children with clubfeet in view of late relapses and secondary late changes.
