Hip dysplasia as risk factor for clinically relevant and radiographic hip osteoarthritis: 10-year results from the CHECK cohort
Main finding · Clinically relevant hip OAResult — go to the resultOdds ratio 2.80 95% CI 1.15–6.79Authors' conclusion
In the long term, baseline hip dysplasia was associated with an increased risk for clinically relevant hip OA, but not for incident radiographic hip OA.
Study context
- Population
- Middle-aged new consulters for hip and/or knee pain (CHECK cohort) with hip pain, available lateral center edge angle (LCEA) and no definite radiographic hip OA (KL grade <2) at baseline; mean age 55.5 (5.4) years, 88% femalehips (251 individuals)
- Participants
- 468 participants
- Exposure
- Hip dysplasia vs no hip dysplasia
- Hip dysplasian = 17
- Outcome
- Clinically relevant hip OA (expert diagnosis on clinical and radiographic data, years 5–10) and incident radiographic hip OA (KL grade ≥2 or total hip replacement)
- Follow-up
- 10 years
