| Abstract | We studied the histology of the cement-bone interface and the regenerated synovium in ten aseptically loosened arthroplasties in rheumatoid patients. In two patients we found rheumatoid nodules at the cement-bone interface and marked lymphoplasmacytic infiltration in another three. Failed joints in osteoarthritic patients did not show these changes, and it seems likely that the presence of abundant immunocompetent cells was due to the background disease. We speculate that rheumatoid inflammation contributed to the process of loosening. |
