    "abstract": "The association between body mass index (BMI) and severity of osteochondritis dissecans (OCD) of the knee at presentation is poorly understood.\nWe hypothesized that adolescents in higher BMI percentiles for age and sex would have OCD lesions that were more severe at their\u00a0initial presentation and located more posteriorly on the condyle as compared with adolescents in lower BMI percentiles.\nCohort study; Level of evidence, 3.\nThis study included patients aged 10 to 18 years who were treated for knee OCD at a tertiary care hospital from 2006 to 2017. Patients with noncondylar OCD or missing BMI data within 3 months of presentation were excluded. Patients were stratified per the Centers for Disease Control and Prevention guidelines as underweight, normal weight, overweight, or obese, and the groups were compared according to age, side of lesion, 4 markers of lesion severity (cystic changes, loose fragments, subchondral fluid, and subchondral edema), and surgical treatment. Lesion angle was measured in reference to a line parallel to the femoral axis drawn through the center of a best-fit circle covering the distal condyle. Data were analyzed using chi-square tests, relative risk, Student \nA total of 77 patients met our inclusion criteria (mean age, 14.2 years; range, 10.1-18.8): 2 were underweight, 50 had normal BMI, 13 were overweight, and 12 were obese. We found correlations between BMI percentile and surgical treatment (\nHigher BMI in adolescents was strongly correlated with multiple markers of severity of knee OCD at initial presentation as well as with more anterior lesions.",
