AUTOMATICALLY DETERMINED MINIMAL JOINT SPACE WIDTH IS LOWER IN SUBJECTS WITH RADIOGRAPHIC HIP OA BUT NOT SIGNIFICANTLY DIFFERENT IF HIP PAIN IS PRESENT: A MULTI-COHORT ANALYSIS

Current epidemiological research on management and prevention of hip OA faces challenges due to the lack of a uniform OA definition. Automated detection of radiographic features on x-ray images across studies such as the minimal JSW (mJSW) could be a solution. However, having radiographic evidence of hip OA does not always imply having symptoms or disability and vice-versa. In order to create an automated hip OA definition, we need to improve our understanding of the interplay between the mJSW and clinical and radiographic factors in a large and diverse population.
