Two studies presented at the recent American College of Rheumatology (ACR 2018) annual meeting in Chicago, IL, address expectations and outcomes following knee and hip replacement in patients with rheumatoid arthritis (RA). In the first study, Blevins and colleagues in New York found that patients with RA have lower expectations for joint replacement than patients with osteoarthritis (OA) but realized greater improvement after the procedure.1 In the second study, Wakabayashi and fellow researchers in Japan discovered that total hip arthroplasty (THA) may have a positive effect on RA disease activity and that reducing RA disease activity may improve function after THA.2 Scroll through the slides for the details of the studies and the take-home points for clinicians.
