Fifty-three cases (feet) were retrospectively reviewed, with 6-month follow-up data available for 72% of participants. The median improvement in dorsiflexion was 15° (95% confidence interval: 12.5°–17.5°, P≤0.05), with 85% achieving dorsiflexion≥10°. At the 6-month follow-up, dorsiflexion remained significantly improved and 12 feet (32%) presented with subsequent relapse. Nine were referred for further casting and three were recommended for extra-articular surgery. Repeat modified Ponseti management clinically and statistically improves passive ankle dorsiflexion in relapsed idiopathic clubfoot. aDepartment of Health Professions, Macquarie University bThe Children’s Hospital at Westmead, Sydney, New South Wales, Australia Correspondence to Kelly Gray, PhD, Department of Health Professions, Faculty of Medicine and Health Sciences, Macquarie University, 75 Talavera Road, Macquarie University, Sydney, 2109 NSW, Australia Tel: +61 2 9850 2795; fax: +61 2 9850 6630; e-mail: firstname.lastname@example.org Copyright © 2017 Wolters Kluwer Health, Inc.
