Detection of simulated complications in all-polymer PEEK knee prostheses: a cadaveric imaging study using Radiography, CT, and MRI

All-polymer PEEK knee prostheses demonstrate favourable imaging characteristics in a cadaveric setting, without any clinically relevant metal-related artefacts and with good visibility of simulated implant complications across radiography, CT, and MRI. These findings suggest potential imaging advantages for future clinical follow-up of polymer-based implant systems, although direct comparative clinical studies are required for confirmation.
