Certain Arthritis Patients Fare Worse After Joint Replacement: Study
In addition, rheumatoid arthritis patients have a higher infection risk after total knee replacement than osteoarthritis patients, the study authors found.
Rheumatoid arthritis, which is felt throughout the whole body, is caused when a person’s immune system attacks his or her own tissues. Osteoarthritis, which is usually felt only in the joints, is caused by wear and tear on the body.
For the study, the investigators analyzed the findings of 40 studies published between January 1990 and December 2011. The studies included arthritis patients aged 18 or older who had hip or knee replacements.
