title: Long-term review of the McGoey-Evans high-friction uncemented total hip arthroplasty.
abstract: To assess the long-term clinical results of uncemented total hip arthroplasty with the McGoey-Evans bipolar high-friction hip prosthesis, the authors reviewed the findings in 86 such hip replacements. The minimum patient follow-up was 5 1/2 years (mean 9 years). Overall, satisfactory results were obtained in 46.5% of cases. There were no deep infections. In contrast to the experience with the cemented hip replacements, the authors found that the results were better in men than women and that most of the revisions were done within 5 years of the original operation. Tissue hypersensitivity resulted in implant loosening in only two cases and no harmful systemic effects arose from the use of this uncemented cobalt-chromium prosthesis. Although this particular hip prosthesis is not recommended because of its inferior design, the findings of the study could be useful in the current practice of uncemented hip arthroplasty.
