Corticosteroid injection in rheumatoid arthritis does not increase rate of total joint arthroplasty.
OBJECTIVE
To determine the relationship between frequent intraarticular corticosteroid injection and subsequent joint replacement surgery.


METHODS
A 1987 database of patients with rheumatic diseases was reviewed to find patients with rheumatoid arthritis (RA) who had received 4 or more intraarticular injections in an asymmetric pattern in a single year.


RESULTS
A subset of 13 patients with an average of 7.4 years of followup was established as the cohort of a 5 year prospective study. In this highly selected cohort of patients with RA in a university practice who received 1622 injections, joint replacement surgery was not significantly more common in the heavily injected joints.


CONCLUSIONS
A strategy of frequent intraarticular steroid injection does not greatly increase, through added risk of joint replacement, the risk inherent in continued disease activity for patients with established RA. Frequent corticosteroid injection may offer some chondroprotection when the alternative is continuous disease activity.
