Patello-femoral joint is an anatomic part of knee joint, even if it's functionally distinct from the condyloid tibiofemoral articulation. Patella is a triangular sesamoid bone embedded In the quadriceps muscle. Its deep surface has a convex medial facet and a concave lateral facet. Medial facet is divided into a medial odd facet and a lateral middle facet. Patellar cartilage is the thickect in the body, reflecting the high contact stresses acting at this level. Patello-femoral stability depends on anatomic factors, passive structures and active components. Patellar shape and throclear walls morphology results in a good congruence and act as a primary stability factor. Medial and lateral retinacula are passive ligamentous structures balancing patello-femoral kinematics during the whole range of motion. Finally, vastus medians obliquus and vastus lateralis muscles complete this complex balance.
