Traditional images of the distal femur place the intercondylar groove
midway between the condyles. The location of the sulcus of the interco
ndylar groove in a large Sudanese skeletal population was verified usi
ng a custom stereotactic device. The results of this study show that t
he femoral sulcus is lateral to the midplane between the 2 femoral con
dyles. This study also shows that the configuration of the sulcus is l
inear and is oriented between the traditional anatomic and mechanical
axes of the femur.
