Cementless total hip arthroplasty in patients with rheumatoid arthritis using a tapered designed titanium hip stem minimum: 10-year results.
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.
