Introduction. The Ponseti regime was introduced in Swansea in 2003 for the treatment of congenital talipes equinovarus (CTEV). The aim of this retrospective cohort study was to compare children treated with this regime with a historical group treated traditionally before then. Materials and Methods. Sixty children (89 feet) were treated with the Ponseti regime between 2003 and 2010. Their notes were compared with notes from 12 children (21 feet) treated between 1995 and 2002. Clinic attendance for serial manipulation and immobilisation (strap/cast) was compared using a two-tailed Mann Whitney U test. Major release surgery was compared using a two-tailed Fisher's Exact test. Results. Children in the historical cohort presented when they were 0–174 days old (median 1 day). They attended 3–35 times (median 22) for serial manipulation and strapping/ plasters. Major release surgery was undertaken on 14 feet (66.7%) when the children were 6–39 months old (median 9 months); 7 had revision surgery. The Ponseti cohort presented when they were 0–73 days old (median 10 days) and attended outpatients 2–19 times (median 7) for serial manipulation and casting. An Achilles tenotomy was undertaken in 54 feet (60.7%) when the children were 45–184 days old (median 71 days) and major release surgery in 17 feet (19.1%) when the children were 10–66 months old (median 21 months). Four children had revision surgery. Discussion. There is a significant reduction in outpatient attendances (Ua = 1313, p = <0.0001) for serial manipulation and reduced rate of release surgery (p = 4.56 × 10. −5. ) since the implementation of the Ponseti regime. The rate of revision surgery in both groups was not significant (p = 0.15), although these samples were small. Conclusion. The Ponseti regime is an effective initial treatment for infants with CTEV compared with traditional treatment. It has decreased the number of clinic attendances and the rate of major release surgery

We investigated 60 patients (89 feet) with a mean age of 64 years (61 to 67) treated for congenital clubfoot deformity, using standardised weight-bearing radiographs of both feet and ankles together with a functional evaluation. Talocalcaneal and talonavicular relationships were measured and the degree of osteo-arthritic change in the ankle and talonavicular joints was assessed. The functional results were evaluated using a modified Laaveg-Ponseti score. The talocalcaneal (TC) angles in the clubfeet were significantly lower in both anteroposterior (AP) and lateral projections than in the unaffected feet (p < 0.001 for both views). There was significant medial subluxation of the navicular in the clubfeet compared with the unaffected feet (p < 0.001). Severe osteoarthritis in the ankle joint was seen in seven feet (8%) and in the talonavicular joint in 11 feet (12%). The functional result was excellent or good (≥ 80 points) in 29 patients (48%), and fair or poor (< 80 points) in 31 patients (52%). Patients who had undergone few (0 to 1) surgical procedures had better functional outcomes than those who had undergone two or more procedures (p < 0.001). There was a significant correlation between the functional result and the degree of medial subluxation of the navicular (p < 0.001, r² = 0.164), the talocalcaneal angle on AP projection (p < 0.02, r2 = 0.025) and extent of osteoarthritis in the ankle joint (p < 0.001).

We conclude that poor functional outcome in patients with congenital clubfoot occurs more frequently in those with medial displacement of the navicular, osteoarthritis of the talonavicular and ankle joints, and a low talocalcaneal angle on the AP projection, and in patients who have undergone two or more surgical procedures. However, the ankle joint in these patients appeared relatively resistant to the development of osteoarthritis.
