根据Allieu Y,Marck G,et al(1990)另外无数的外科医生开始越来越多的假体在各种物质代替单一的组合作为替代移植或关节成形术。金属假体被发现存在和更长更大的生物相容性。这包含髋关节假体的摩尔和汤普森,和膝关节假体(胫骨高原)MacIntosh和麦基弗。未替换结合外部,待疼痛的基础,特别对病人与关节炎的关节。根据Rolf O,Gohlke F(2004)要解决这个挫折,完成etalon-metal假肢的髋关节和膝关节的关节。早期的草图可能不提供正常的目的相结合,经历了从失事率升高引发了放松,过度磨损和感染。

This encompassed the hip prosthesis by Moore and Thompson, and knee prosthesis (tibial plateau) by MacIntosh and McKeever.
