| Summary: | Abstract Clubfoot is one of the common orthopaedic deformities. However, regardless of its’ treatment high success rate, recurrence of the deformity is a serious issue. The aim of this study is to evaluate if radiographic angles can be used for clubfoot recurrence prediction. This is a prospective study on 91 patients (134 feet) with mean age of 9.5 ± 2.3 days and male/female ratio of 2/1 on patients with congenital clubfoot admitted to our hospital. Pre and one-year post-tenotomy tibiocalcaneal (TIC-L), talocalcaneal (TC-L) and calcaneal-first metatarsal angles (C1M-L) in the lateral view of the patients' radiographs, and their recurrence status until three years were measured. Ten feet experienced relapse. The mean pre and one-year follow-up measurements of TC-L, C1M-L, and TIC-L angles were significantly different between patients who experienced relapse and others (P < .05). The cut-off points of 1.75 and 6.5 for one-year follow-up Pirani and Dimeglio scores for recurrence prediction were suggested respectively. Also, cut-off points of 26.5 and 79.5 for one-year follow-up TC-L and TIC-L angles for recurrence prediction were calculated, respectively. We demonstrated that the pre-tenotomy and one-year follow-up TIC-L, TC-L, and C1M-L angles are helpful in clubfoot recurrence prediction after Ponseti treatment.
