Figure 3.

An illustrative case (right knee) with previous nonanatomic placement of the femoral socket. (A) On the navigation computer screen, the surgeon can identify the whole image of the lateral wall of the femoral notch during surgery, whereas the natural morphology of the lateral wall of the intercondylar notch was destroyed by the previous reconstructive surgery. (B) Arthroscopic view of the lateral wall of the femoral notch with the previous non–anatomically placed femoral socket from the anteromedial portal. The knee was at 90° of flexion. (C) Arthroscopic view of the newly created rectangular femoral socket (the same way as in B). (D) Medial view of a 3D CT reconstruction of a right distal femur at 1 week after revision shows the previous nonanatomic femoral socket (anterior), the newly created rectangular socket (posterior) for the BPTB graft with a slight overlap with the aperture of the previous one, and the bone plug. (E) Lateral view of a 3D CT scan shows the new femoral tunnel (proximal) with no interference with the previous bone tunnel (distal) and the EndoButton.
