Abstract
Design: Cross sectional analysis of a prospective cohort.
Setting: 35 general practices across the UK.
Subjects: 195 patients (63 male, 132 female) aged 40 years and over presenting with a new episode of hip pain
Results: The prevalence of acetabular dysplasia in this study of new presenters with hip pain was high (32%). There was no significant relationship between acetabular dysplasia and radiographic OA overall.
Conclusions: The high prevalence of acetabular dysplasia across all grades of OA severity suggests that dysplasia itself may be an important cause of hip pain ("symptomatic adult acetabular dysplasia").
