The Effect Of Stem Surface Treatment And Substrate Material On Joint Replacement Stability: An In-Vitro Investigation Into The Stem-Cement Interface Mechanics Under Various Loading Modes, Yara K. Hosein

Electronic Thesis and Dissertation Repository

Mechanical loosening is a common mode of joint replacement failure. For cemented implants, loosening at the implant-cement interface may be affected by stem surface design. Altering the surface topography facilitates the infiltration of bone cement onto the stem, creating a mechanical interlock, improving interface stability. However, few in-vitro studies have investigated this. Therefore, the purpose of this thesis was to investigate the effect of stem surface treatments and substrate materials on stem-cement interface stability in-vitro.

Four separate studies were performed to assess the stability of various stem surface treatments, with two substrate materials, under three loading modes. Titanium and …
