Functional, clinical, and radiological outcomes of split anterior tibial tendon transfers in patients with sequelae of congenital talipes equinovarus.

OBJECTIVE

This retrospective analysis aimed to assess the effectiveness of Split Tibialis Anterior Tendon Transfer (Split TATT) in treating residual idiopathic congenital talipes equinovarus (CTEV) deformities.

METHODS

15 patients (20 feet) with CTEV, with a mean age of 6.4 ± 3.2 years, initially treated with Ponseti casting, underwent Split TATT. Clinical and radiological evaluations, including Diméglio and Garceau scores, dorsiflexion, and X-ray measurements, were conducted preoperatively and post-operatively at a minimum 2-year follow-up.

RESULTS

Significant improvements were observed in Diméglio and Garceau scores. Dorsiflexion increased by an average of 3°, and radiological analysis revealed nuanced changes. Despite a weak Kappa coefficient, positive trends in dorsiflexion and Garceau scores were noted. Preoperative Garceau scores did not reliably predict postoperative results.

CONCLUSION

Split TATT demonstrates promising results in improving muscular balance and functional outcomes in CTEV. While radiological changes are subtle, positive trends in clinical scores indicate meaningful outcomes.

LEVEL OF EVIDENCE: IV Retrospective study.
