Radiographic case definitions and prevalence of osteoarthrosis of the hipA survey of 4 151 subjects in the Osteoarthritis Substudy of the Copenhagen City Heart Study

Abstract

We found that minimum JSW < or = 2.0 mm was the radiographic criterion having the closest association with self-reported hip pain. Using composite OA scores emphasizing the relatively inconsequential formation of cysts, osteophytes and subchondral sclerosis runs the risk of over-inflating the prevalence of hip OA in men and of underestimating hip OA prevalence in women.
