The relationship between MRI features and knee pain over 6 years in early knee osteoarthritis

Purpose: The tissue of origin for knee pain is still unclear in knee osteoarthritis (OA). Therefore, we aimed to explore whether MRI features suggestive of knee OA are associated with the presence of knee pain in early-stage OA development using a within person (between knees) study design. Methods: We included 294 participants from the Osteoarthritis Initiative incidence/progression cohort (mean [SD] age 50 (3) years, 50% women), with baseline...
