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