We combinedx-ray computed tomography imaging(high-resolution peripheral computed tomography, HR-pQCT)and digital volume correlation (DVC)on human cadaveric femurs to quantify permanent bone damage and residual strains due topress-fit femoral knee implantation. The apparent bone damage occurs up to 2 mm in depth, with residual peak third principal strains exceeding the yield strain of bone.
