Inclusion criteria included: primary hip surgery, 18 to 55 years of age, and CT imaging of the hips. Exclusion criteria included: revision hip surgery, mild or borderline hip dysplasia, hip synovitis, and incomplete radiographs and medical records. NSA was measured on CT imaging. ACT was measured using magnetic resonance imaging (MRI).

Multivariable regression analysis revealed that NSA (P\u2009=\u20090.002) and sex (P\u2009=\u20090.001) were significantly negatively correlated with ACT.
