Lesion location, laterality, and all patient demographics were recorded. Ankle OCD incidence was determined for the group as a whole and by both sex and age group (divided into age groups of 2-5, 6-11, and 12-19 years). The risk for ankle OCD for age group, sex, and ethnicity was assessed using multivariate logistic regression models.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      A total of 85 patients fit the inclusion criteria, and 71.8% of lesions found were in the medial talus, 56.5% of lesions were right sided, and none were bilateral. No ankle OCD lesions were found in 2- to 5-year-olds. The incidence of ankle OCD in patients aged 6 to 19 years was 4.6 per 100,000 overall and 3.2 and 6.0 per 100,000 for male and female patients, respectively. Patients aged 12 to 19 years represented the vast majority of those with OCD, with an incidence of 6.8 per 100,000 compared with 1.1 per 100,000 in those 6 to 11 years of age. In those aged 6 to 11 and 12 to 19 years, female patients had a respective incidence of 1.5 and 8.9 per 100,000, whereas male patients had a respective incidence of 0.7 and 4.8 per 100,000. The overall female\/male ratio of ankle OCD was 1.6:1. Multivariate logistic regression analysis revealed a 6.9 times increased risk for ankle OCD in patients aged 12 to 19 years compared with those aged 6 to 11 years (95% CI, 3.8-12.5;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; .0001), and female patients had a 1.5 times greater risk for ankle OCD than male patients (95% CI, 1.0-2.3;\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = .06).
