The aim of this report was to investigate the clinical course of patients with FOPE zones. Three adolescent patients with a FOPE zone in the knee were treated and observed for a maximum of 2 years. No symptoms or leg-length discrepancy developed at the final follow-up after conservative therapies. This is the first report on the follow-up of FOPE zones with a maximum of 2 years. The results suggest that observation of FOPE zones may be sufficient without invasive examinations and treatment. aDepartment of Orthopedic Surgery bDepartment of Pediatric Orthopedic Surgery, Osaka City General Hospital, Osaka, Japan Correspondence to Hideki Ueyama, M.D, Department of Orthopedic Surgery, Osaka City General Hospital, Miyakojimahondori 2-13-22, Miyakojima Ward, Osaka City, Osaka 5340021, Japan Tel: +81 6 6929 1221; fax: +81 6 6929 2041; e-mail: email@example.com Copyright © 2018 Wolters Kluwer Health, Inc.
