Figure 1.

(A) Arthroscopic view of the lateral wall of the femoral intercondylar notch from the anteromedial portal in a right knee. The knee was at 90° of flexion. The tip of the femoral guide was placed inside the anatomic femoral footprint through a far anteromedial portal. The dashed line shows the nonanatomic previous femoral socket. (B) Navigation view of the lateral wall and the roof of the femoral intercondylar notch on the 3D reconstructed image. The previous bone tunnel and the retained metal hardware can be observed on the axial, coronal, and sagittal 2-dimensional images.
