Are ultrasonographic signs of inflammation predictors for response to intra-articular glucocorticoids in knee osteoarthritis?

Objectives: To investigate the predictive value of ultrasound (US) characteristics for the effect of intra-articular glucocorticoids in knee osteoarthritis (OA).

Methods: In this prospective cohort study, 62 patients with symptomatic knee OA (clinical knee OA criteria, pain>4 on a Numerical Rating Scale (NRS; 0-10)) received an intra-articular glucocorticoid injection (40 mg triamcinolone acetonide). Patients with NRS pain ≤4 at 4 weeks were defined as responders.
