The Fovea provides attachment for the Ligamentum Teres
(ligament of the head of the femur)
This attaches to the acetabulum of the pelvis and helps stabilise the hip joint

Distal Femur
Distal Femur – anterior view
If the shaft is held perpendicular to the floor, the medial condyle is seen to project further inferiorly compared to the lateral condyle
right femur
In the upright skeleton, the shaft of the femur lies obliquely and the condyles
appear to be aligned distally
If the shaft is held perpendicular to the floor, the medial condyle is seen to project further inferiorly compared to the lateral condyle
