The aim of this study was to determine the polyethylene wear rate of Phase 3 Oxford Unicompartmental Knee Replacement bearings and to investigate the effects of resin type and manufacturing process. A total of 63 patients with at least ten years’ follow-up with three bearing types (1900 resin machined, 1050 resin machined, and 1050 resin moulded) were recruited. Patients underwent full weight-bearing model-based radiostereometric analysis to determine the bearing thickness. The linear wear rate was estimated from the change in thickness divided by the duration of implantation.Objectives
Methods
The objective of this study was to compare the early migration
characteristics and functional outcome of the Triathlon cemented
knee prosthesis with its predecessor, the Duracon cemented knee
prosthesis (both Stryker). A total 60 patients were prospectively randomised and tibial
component migration was measured by radiostereometric analysis (RSA)
at three months, one year and two years; clinical outcome was measured
by the American Knee Society score and the Knee Osteoarthritis and
Injury Outcome Score.Objectives
