Although several studies have shown a relationship between hip displacement and acetabular dysplasia, relatively few have evaluated the association between quantitative acetabular dysplasia and related factors, such as Gross Motor Function Classification System (<jats:styled-content style=\"fixed-case\">GMFCS<\/jats:styled-content>) level.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>We performed a morphometric analysis of the acetabulum in patients with CP using multiplanar reformation of computed tomography data. The three directional acetabular indices (anterosuperior, superolateral, and posterosuperior) were used to evaluate acetabular dysplasia. Consequently, linear mixed\u2010effects models were used to adjust for related factors such as age, sex, <jats:styled-content style=\"fixed-case\">GMFCS<\/jats:styled-content> level, and migration percentage.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 176 patients (mean age 9y 5mo, range 2y 4mo\u201319y 6mo; 104 males, 72 females) with CP and 55 typically developing individuals (mean age 13y 6mo, range 2y 5mo\u201319y 10mo; 37 males, 18 females) in a comparison group were enrolled in this study. Statistical modelling showed that all three directional acetabular indices independently increased with <jats:styled-content style=\"fixed-case\">GMFCS<\/jats:styled-content> level (<jats:italic>p<\/jats:italic>&lt;0.001) and migration percentage (<jats:italic>p<\/jats:italic>&lt;0.001).<\/jats:p><\/jats:sec><jats:sec><jats:title>Interpretation<\/jats:title><jats:p>Acetabular dysplasia was independently affected by both the amount of hip displacement and the <jats:styled-content style=\"fixed-case\">GMFCS<\/jats:styled-content> level.
