However, the association between hip pain and radiographic hip osteoarthritis (ROA) remains uncertain. Aim: To examine the association between hip pain and hip ROA. Design and setting: Cross-sectional analysis of a Dutch cohort, the Cohort Hip and Cohort Knee (CHECK) study. Methods: Participants (45-65 years) experienced hip and/or knee pain for which they had no prior consultation or were within 6 months of their first consultation to a general practitioner. Using weight-bearing anterio-posterior pelvis radiographs, definite and early-stage hip ROA were defined as Kellgren and Lawrence grade ≥2 and ≥1, respectively. Presence of ROA and pain was assessed in both hips of all participants. We assessed the association between hip pain and ROA using generalized estimating equations. Results: The prevalence of definite ROA was 11.0% (218/1982 hips), while the prevalence in painful and pain-free hips was 13.3% (105/789) and 9.5% (113/1193), respectively. The early-stage prevalence was 35.3% (700/1982 hips), 41.2% (325/789) among painful and 31.4% (375/1193) among pain-free hips. Compared to pain-free hips, the odds ratio of painful hips was 1.51 (95% CI 1.16-1.98) for definite and 1.47 (95% CI 1.24-1.75) for early-stage ROA. Conclusion: Hip pain was associated with definite and early-stage hip ROA, yet the overall ROA prevalence was modest and the prevalence among pain-free hips was substantial. Therefore, radiographs hardly help to identify hip OA patients among patients who recently newly presented with hip or knee complaints. ER -
