CT with external loading of the knee can be used for the detection of loosening of the tibial component after total knee arthroplasty (TKA) [1,2], which occurs more frequently than loosening of the femoral component [3]. Compared to conventional radiography — which is known to have limited sensitivity for detecting tibial component loosening [4] (around 70–83 % [5,6]) — load induced CT enables direct assessment of mechanical implant stability rather than relying on indirect markers such as radio…
