OBJECTIVES: To determine the prevalence of acetabular dysplasia in subjects presenting with hip pain to primary care and its relationship with radiographic osteoarthritis (OA) of the hip. 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").
