The first generation, metal-on-metal articulation from cobalt-chromium-molybdenum alloy produced by Sulzer Ltd. has been in use for 40 years. Former drawbacks concerning geometry, tolerance or metallurgy have been eliminated in the second generation METASUL components used since 1988. These are also free of disadvantages, such as potential fracture, shown by other hard-on-hard bearing couples. For 14 years now METASUL components have not been responsible for any repeat operation due to loosening. Both clinical and experimental outcomes show that yearly wear has been negligible (in the order of microns) and this allows us to expect the metal-on-metal coupling to function for periods not a achieved so far by any other hip prosthesis. Hip replacements based on METASUL are better than those involving metal-on-polyethylene or ceramic-on-polyethylene. Up to now the need for repeat operations has not been associated with the MATASUL coupling system. Loosening has always been due to other reasons. It can therefore be expected that, in choosing prosthetic devices and surgical techniques, METASUL hip replacements will play a leading role.
第一代由苏尔寿有限公司生产的钴铬钼合金金属对金属关节已经使用了40年。自1988年起使用的第二代METASUL部件消除了先前在几何形状、公差或冶金方面的缺陷。这些部件也没有其他硬对硬轴承配对所表现出的潜在断裂等缺点。14年来，METASUL部件从未因松动导致任何再次手术。临床和实验结果均表明，每年的磨损可忽略不计（以微米计），这使我们预计金属对金属关节的使用期限将超过目前任何其他髋关节假体所能达到的。基于METASUL的髋关节置换术比那些涉及金属对聚乙烯或陶瓷对聚乙烯的置换术更好。到目前为止，再次手术的需求与MATASUL连接系统无关。松动一直是由其他原因引起的。因此可以预期，在选择假体装置和手术技术时，METASUL髋关节置换术将发挥主导作用。
