Aseptic Loosening. (A,B) Frontal radiograph of the knee shows lucency (black arrow) along the superolateral aspect of the femoral component of a total knee arthroplasty. (C) Planar image from a Tc-99m MDP bone scintigraphy shows increased uptake in the superolateral aspect of the femoral component. (D) SPECT/CT fusion shows that the focus of increased uptake corresponds to the area of lucency seen on radiographs. (Images used with permission of Dr Susanna C.
