Tibiotalar Incongruency in Clubfoot Treated Operatively Is a Predictor of Worse Outcome at a Mean of 26 Years.
The traditional approach to congenital talipes equinovarus (CTEV) has relied on stepwise manipulations, followed by surgery in severe or recurrent cases. The 3 aims of this study were: (1) to report long-term results of clubfoot treated by posterior capsulectomy and selective release (PCSR); (2) to determine the reliability of a visual scale in the assessment of intraoperative tibiotalar incongruency (TTI); and, (3) to assess the role of TTI as a prognostic factor. We reviewed data regarding 95 CTEV (65 patients) treated by PCSR at a minimum follow-up of 20 years. Patients underwent a physical and radiographic examination, and were assessed through multiple clinical scores. The inter- and intraobserver reliability for TTI evaluation was calculated on clinical photographs. Based on TTI, 52 CTEV were divided in 2 groups (30 congruent vs 22 incongruent) and compared. At a mean follow-up of 26.8 (from 24 to 31) years, 52 CTEV (38 patients) were available for the analysis. Functional results were globally satisfactory. The inter- (κ = 0.748) and intraobserver analysis (κ = 0.688) for the TTI visual assessment showed substantial agreement. In patients with incongruency, patient reported outcomes were significantly worse, with also a greater development of subtalar (p = .02), talonavicular and calcaneocuboid arthritis (p < .001 for both). In treating severe CTEV, the surgical PCSR performed in the first year of life obtains satisfactory clinical and patient-recorded outcomes at over 25 years of follow-up. The visual assessment of TTI is reproducible and potentially represents a long-term prognostic factor.
