A comparative surface topographical analysis of explanted total knee replacement prostheses: Oxidised zirconium vs cobalt chromium femoral components

Total Knee Replacement (TKR) offers improved mobility and pain relief for many people suffering with the debilitating disease of osteoarthritis [1 –4]. In the longer-term, wear of the polyethylene (PE) component and PE wear-debris associated problems continue to limit TKR longevity. The 2016 Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) [1] and the National Joint Registry (NJR) Annual Report for England, Wa les, Northern Ireland and the Isle of Man [3] both cite aseptic loosening as the main reason for TKR revision at 10 years and beyond.
