Abstract
Modern metal-on-metal bearings were reintroduced on the market by Prof. B.G. Weber in 1988. Since this date, more than 500,000 bearings have been implanted world-wide with excellent clinical results.
The goals of this presentation are to review critically the long-term published clinical results for metal-on-metal bearings (small and large diameter) and to investigate the current concerns (ions release, allergic reactions, pseudo-tumours…) about metal-on-metal bearings. Based on this review, the benefice-risk ratio of metal-on-metal bearings will be discussed.
