Clubfoot is an orthopedic congenital malformation of the lower limb of the newborn evaluated by the Dimeglio score. There is a deficit of muscular balance between the agonists and antagonists to the deformity. The Dimeglio score takes into account the muscular activity but only up to one point out of 20. This study proposes to use a muscle scale inspired by the Dimeglio score to see if there is a correlation between muscle activity and the risk of tenotomy before 1 year. It will also assess the inter-examiner reproducibility of this scale. This study is a prospective cohort study with a duration of 8 years to include about 100 feet. Infants with idiopathic Clubfoot treated with the functional method at up to 15 days of life will be included. Feet will be assessed at an inclusion visit and then at 3-6-12 months. The primary endpoint will be the need for Achilles tenotomy before 1 year of age. The secondary endpoint will be inter-examiner reproducibility determined by statistical analysis. The expectation of this study would be to define a predictive factor of the evolution of the PBVE in order to refine the treatment earlier.
