What is it about?

This is the rst study to use accurate measurements from pre-revision 3DCT to compare tibial and femoral orientation in all three planes with retrieval ndings in total knee replacements. A signi cant correlation between implant position and polyethylene surface damage was found. These results showed the importance of optimizing component position to minimize polyethylene damage. Further analysis involving more accurate polyethylene wear measurements are fundamental to fully understand the role of components’ orientation in TKAs.

Why is it important?

It will allow a better understanding of the in-vivo loading of knees after TKA. In particular for unhappy TKA patients it will allow to identify the failure mode.


With the combined assessment of 3D imaging and retrieval analysis the real effects of loading in patients after total knee arthroplasty are assessed. Work with is only possible due to the collaboration of kneedoctor.ch and LIRC. In future, larger scaled studies will be performed investigating the effect of specific type of TKA.
