Need and sequence of large joint replacements in rheumatoid arthritis. A 25-year follow-up study.
OBJECTIVE
The aim of the present study was to evaluate the number and sequence of large joint replacements (LJR) performed in long-term rheumatoid arthritis (RA) from an inception cohort of 103 patients with rheumatoid factor (RF)-positive RA followed over 25 years.


METHODS
A total of 83 patients attended the 15-year and 68 patients the 20-year follow-up. Patient documents and radiographs were evaluated in the beginning of 2001 and a complementary interview was arranged to assess the number and sequence (timing) of LJRs performed.


RESULTS
The cumulative number of LJRs performed for 22 patients (19 women) during the 25 years of follow-up was 41. Seventeen total hip joint replacements (THR) (42% of the total number of 41 LURs) were performed on 13 patients, median time from the diagnosis to the operation being 14 years; 14 total knee replacements (TKR) (34%) on 11 patients (after a median time of 17 years); 3 total shoulder replacements (TSR) (7%) on 3 patients (median time of 18 years); and 7 total elbow replacements (TER) (17%) on 4 patients (median time of 21 years), respectively. Six patients had undergone three or more LJRs during the follow-up period.


CONCLUSIONS
During our 25 years of follow-up, in 27% of RA patients LUR was needed, and 41% of them needed more than one replacement.
