Grupp TM, et al. - Researchers compared tibial components made out of cobalt-chromium vs a ceramic zirconium nitride multilayer coating in terms of cemented implant fixation strength, and examined their behavior with 5 distinct bone cements in a standardized in vitro model for the examination of the implant-cement-bone interface conditions. They also investigated if initial fixation strength represents a function of timing of the cement apposition and component implantation by an early, mid-term, and late usage within the cement-specific processing window. They determined the implant fixation strength following cementation of tibial components by conducting an in vitro inquiry employing a synthetic polyurethane foam model. Findings revealed the beneficial impact of the apposition of bone cements and tibial tray implantation in the early to mid of the cement-specific processing window on interface fixation in total knee arthroplasty.
