Weak associations between structural changes on MRI and symptoms, function and muscle strength In relation to knee. osteoarthrltls

摘要

Purpose To explore associations between MRI-defined structural abnormalities and clinical features related to knee osteoarthritis (OA).Methods Structural and clinical knee OA features were assessed in 87 women (45 with knee OA symptoms). Structural features were quantified by the Kellgren and Lawrence grade on radiography and by the Boston-Leeds Osteoarthritis Knee Score on MRI. Clinical features were assessed using the Knee Injury and Osteoarthritis Outcome Score, functional tests and muscle strength measurements. Associations were examined using regression analyses.
