title: The M.E Müller straight stem prosthesis: 15 year follow-up. Survivorship and clinical results.
abstract: The aim of the study was to document the long-term clinical and radiologic results as well as the 15 year survival of a single cemented straight stem. Our series consisted of consecutive patients with 161 straight stem prostheses implanted between 1984 and 1987 in 152 patients. Follow-up was performed prospectively at 1, 2, 5, 10 and 15 years post-operatively. Seven stems were revised due to aseptic loosening, the 15 years survival rate being 94%. There were 18 acetabular revisions. Pain and patient satisfaction declined slightly over the study period. We observed a more prominent health-related decline of functional results. This effect was mainly due to aging. Younger patients showed better clinical results, but also a higher revision rate.
