The importance of fluid-film lubrication mechanisms experienced in hip implants is reviewed. For the different types of hip implants currently used in clinical practice, including conventional/cross-linked polyethylene-on-metal/ceramic, metal-on-metal and ceramic-on-ceramic bearing couples, a detailed review is presented of theoretical fluid-film lubrication analyses along with friction measurements and wear studies, both having a strong emphasis on the fluid-film mechanisms involved. Future studies and improvements of hip implants from a fluid-film lubrication point of view are discussed.
