Certain Arthritis
Patients Fare Worse After Joint Replacement: Study

WEDNESDAY, Nov. 28
(HealthDay News) -- Patients with rheumatoid
arthritis
are more likely to suffer hip dislocation after hip replacement
surgery than those with osteoarthritis,
a new study says.
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.
