In symptomatic acetabular dysplasia, specific radiographic angles correlate with more severe labrochondral disease, and a majority of cases have abnormalities amenable to arthroscopy.
Acetabular rim disease is common in symptomatic acetabular dysplasia, and 63% of cases have a central compartment abnormality amenable to arthroscopic treatment. Lateral center-edge angle 20° are associated with more severe labrochondral disease.
