Background and objectives. Congenital talipes equinovarus (CTEV) is one of the most common congenital defects of the musculoskeletal system, with an incidence ranging from 0.9 to 7 cases per 1000 live births. Deformity in CTEV does not resolve on its own, and if proper treatment is not provided, it will worsen as the patient reaches adulthood and cause side effects such as pain and long-term dysfunction. The classification of CTEV deformities is an important component of evaluation before therapy and is useful in assessing progress in therapy. In this study, we retrospectively investigated the association between clinical outcomes and initial Dimeglio score before therapy, initial Pirani score before therapy, and patient age at presentation. Materials and methods. This study was an analytical study with a retrospective case-control design. The subjects in this study were patients with CTEV who were treated with the Ponseti method. Results. Based on the classification by age implemented by the researchers, 12 participants (30.8%) were in the ≥ 12 months age group, followed by 10 (25.6%) in the 2–7 months age group, 9 (23.1%) in the < 2 months age group, and 8 (20.5%) in the 8–11 months age group. Further, statistically, initial Dimeglio score, initial Pirani score, and patient age at presentation had a moderate correlation with treatment outcome assessed by ACT score. Conclusions. This study indicates an association between low initial Dimeglio score, low initial Pirani score, and early age at presentation with quality of life and high ACT score.
