Inclusion criteria were set as follows: (1) age\u2009\u2264\u200917 years with an open growth plate, (2) follow\u2010up magnetic resonance imaging, and (3) absence of preoperative OCD. Consequently, 52 patients were retrospectively investigated. Average age during surgery, body mass index (BMI), and follow\u2010up duration were 12 years [95% confidence interval (CI) 11\u201313], 19.2\u00a0kg\/m<jats:sup>2<\/jats:sup> (95% CI 18.4\u201320.1), and 27.3\u00a0months (95% CI 20.9\u201333.7), respectively. Age, sex, sports activities, BMI, symptomatic OCD in other joints, postoperative rehabilitation, preoperative shift of DLM by Ahn\u2019s classification, surgical procedures (saucerization alone or with stabilization, and subtotal meniscectomy), and postoperative meniscal width were analyzed as possible predictive factors.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Postoperatively, 42 patients without OCD and 10 with OCD were observed.
