INTRODUCTION: Frequency of anterior cruciate ligament rupture depends of anatomical parameters of distal femur and intercondylar notch. PURPOSE: Purpose of this work is identification relation between femur length and morphometrical parameters intecondylar notch, measuring in two levels. METHOD: A hundred femur's (medley population of 48 right and 52 left femurs), from osteological collection Department of Anatomy 'dr. Niko Miljanić' in Belgrade measured. Measurement was in two levels. Epicondilar width, width of medial and lateral condyls and intercondylar width, had been measured in level of popliteal sulcus and on the widest place, after that notch width index had been determinated. RESULTS: Absolute values of morphometrical parameters distal femur's are in positive relation with her length (p <0.01), but notch width index is not, as in level of popliteal sulcus, as on the widest place (p>0.05). CONCLUSION: Femur's length increasing also produces increasing of absolute anatomical parameters of distal femur which can produce rupture of anterior cruciate ligament, while relative dimensions do not show femur's length increasing.
