TOTAL HIP-ARTHROPLASTY IN RHEUMATOID-ARTHRITIS - COMPARISON OF CEMENTED AND UNCEMENTED IMPLANTS

In a group of patients who underwent total hip arthroplasty because of rheumatoid arthritis, the outcome in 42 hips was assessed. There were 17 cemented and 25 uncemented prostheses. The average follow-up was 5 years for cemented prostheses and 3 years for uncemented proStheses. The average Harris hip scores were similar in the two groups (84 and 8 6 respectively). Radiologically, the incidence of migration of femoral and acetabular components was similar in the two groups. Component mi gration was not affected by component fixation. Uncemented implants ma y have a role in hip arthroplasty in patients with rheumatoid arthriti s.
