Associations and Diagnostic Accuracy of Ultrasound Features in Knee Osteoarthritis: Cross‐Sectional Results From a Large Community‐Based Cohort

We identified common US features in participants with and without KOA, along with significant associations between US features and rKOA, symptomatic rKOA, and symptoms. US-based diagnosis of rKOA shows promise for general use. US is a valuable and accessible modality for assessment of knee OA features in clinical and research settings, including those with limited resources.
