Introduction: Relapsed clubfoot is defined as the recurrence of any component of deformity after a complete correction. While the Ponseti method has been known to have excellent outcomes, several relapse cases have been reported. Thus, further surgical intervention is needed to achieve a good and reliable long-term outcome.
Presentation of the case: We report a presentation of a 5-year-old boy who came to the clinic with a relapsed bilateral clubfoot after serial Ponseti casting. Plantar fascia release, Achilles tendon lengthening, and tibialis anterior tendon transfer (TATT) were performed respectively followed by an above-knee cast. The patient gained acceptable walking balance and ability to perform high impact sports at one year follow-up.
Clinical discussion: There are several factors contributing to the relapse clubfoot including adherence to post op foot abduction brace (FAB) protocol, muscle imbalance or inadequate correction of initial deformities. The current case report described a relapse clubfoot following serial Ponseti casting caused by non-compliance of the use of foot abduction brace. Further surgical interventions must be performed in the presence of relapse case of clubfoot.
Conclusion: Relapse clubfoot is the presence of any recurring deformity following correction. Surgical intervention, especially TATT procedure provides a favorable outcome in treating patients with relapse clubfoot.
