X-rays of the right knee with distal femur and proximal tibia in June 2015. Left (AP view): some bone resorption at the prosthesis-tibia interface. Intact, well-fixed prosthesis. Right: lateral X-rays demonstrated a small step (arrow) of the lateral femur condyle of the prosthesis.

Revision surgery took place in August 2015 and showed breakage of the lateral part of the femoral component (Figure 2).
The evaluation of the fractured prosthesis area demonstrated that the breaking line ran through the thread hole where metal augmentation blocks can be added and secured in case of bony defect.
