Results from this study indicated there was a significant increase in joint replacements in New Zealand for patients with osteoarthritis between 1999 to 2015. However, apart from elbow replacements, joint replacement rates did not decline for patients with rheumatoid arthritis.
Researchers identified patients with RA and OA from the New Zealand Joint Registry. Investigators also identified patients with RA who underwent elbow replacements. Data from medical records were collected and included patient demographics, current and previous disease-modifying antirheumatic drug use, previous joint replacement, oral or intra-articular steroid use, radiographic erosions and complications.
Results showed the rates of joint replacement were higher for patients with OA vs. patients with RA, apart from elbow replacements. In addition, the rates for hip, shoulder, knee and ankle replacement were stable for patients with RA. From 2008 to 2013, there was a decrease in elbow replacements for RA. – by Monica Jaramillo
