The results of cementless tapered designed femoral stem were studied at a minimum 10-year follow-up in a non-selected, consecutive group of 27 patients (39 hips) with rheumatoid arthritis. Clinical and radiological analyses were performed in 27 hips, 17 patients (mean age at surgery 45 years) after a mean of 12 years. The postoperative Harris hip score was excellent for 14 hips, 9 hips were rated as good and 4 hips were fair or poor. No stem had to be revised for aseptic loosening. Proximal stress shielding was observed in 26 hips (96%); heterotopic ossification was present in 11 hips (41%). Six hips required revision of the acetabular component. With uncemented tapered femoral fixation excellent 12-year results are achieved in patients with rheumatoid arthritis.

D012189 Retrospective Studies Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
