RT Journal Article SR Electronic T1 Intra-articular treatments in osteoarthritis: from the symptomatic to the structure modifying JF Annals of the Rheumatic Diseases JO Ann Rheum Dis FD BMJ Publishing Group Ltd and European League Against Rheumatism SP 478 OP 482 DO 10.1136/ard.2003.013771 VO 63 IS 5 A1 Gossec, L A1 Dougados, M YR 2004 UL http://ard.bmj.com/content/63/5/478.abstract AB The symptomatic and structural efficacy of intra-articular (IA) injections is reviewed. IA corticosteroid injections are rapidly effective, but their symptomatic benefit is short lived. Hyaluronan has delayed onset of efficacy but its benefit for pain may be longer lasting. Lavage and debridement are probably not as efficacious as once thought in osteoarthritis.
