![]() ![]() On the medial wall of the notch is a larger site where the posterior cruciate ligament (PCL) originates. The lateral wall of the notch has a flat impression where the proximal origin of the anterior cruciate ligament (ACL) arises. The intercondylar notch separates the two condyles distally and posteriorily. The anterior extensions of both condyles form a fossa for the patella to sit in extension. The contact surface of the patella is derived mostly from the lateral condyle. The lateral condyle has a greater posterior excursion than the medial. The sulcus represents the deepest point in the trochlea relative the mid plane between the condyles, the sulcus lies slightly laterally. Anteriorily the condyles are separated by a groove, the femoral trochlea. The lateral condyle is slightly wider than the medial condyle at the centre of the intercondylar notch. The long axis of the lateral condyle is slightly longer and is placed more sagittal than the long axis of the medial condyle. The lateral condyle is slightly shorter than the medial. The lateral condyle viewed from the side has a sharply increasing radius of curvature posteriorily. In shape and dimensions the femoral condyles are asymmetric the larger medial condyle has a more symmetrical curvature. The inferior, oblong surfaces of the condyles are separated by the intercondylar fossa which houses the cruciate ligaments. ![]() The inferior, posterior oblong portions of the condyles articulate smoothly with the tibial plateau, whereas the central anterior surface between the condyles articulates with the facets of the patella. The distal aspect of the femur broadens into the medial and lateral condyles with all but the sides of these condyles being articular and involved in the knee joint. The shaft of the femur is nearly cylindrical, fairly uniform in calibre and the shaft has a bow with the apex anteriorily progressing from proximal to distal. The femur is the longest and strongest bone in the body. ![]()
