Evaluate the predictive value of the PBS-score in predicting recurrence of idiopathic clubfoot, measured as need for additional treatment.

Using a consecutive inclusion, we aim to include 60 children and register data proposed by the COS for PEVA. All items of the PBS-score are video-documented, and dynamic foot pressure during walking is recorded during a clinical visit at the Motion Analysis Lab at Karolinska University Hospital. Children and caregivers will complete Roye's score, a disease-specific PROM and Oxford Foot and Ankle Questionaire-child (OxFAQc). For children aged 6 years or older, standing radiographic imaging of both feet will be performed. Inclusion criteria include: age 4-8 years, a diagnosis of idiopathic clubfoot, ability to walk 10 m repeatedly, and ability to communicate verbally (and in writing for caregivers) in Swedish or English. Included children will be followed prospectively during five years through clinical visits and medical records, where need for additional treatment (casting, braces and/or surgery) is the primary endpoint.

Inclusion Criteria:

• age 4-10 years, a diagnosis of idiopathic clubfoot, ability to walk 10 m repeatedly, and ability to communicate verbally (and in writing for caregivers) in Swedish or English.

Exclusion Criteria:

• Syndromic clubfoot
