Among the structures that make up the knee joint, the meniscofemoral ligaments (MFL) are considered unstable elements which are related to the posterior cruciate ligament (PCL). In order to correlate the MFL with the PCL and classify the poste- rior meniscofemoral (PMFL) with respect to PCL, 30 fixed knees of Chilean individuals were studied, all belonging to the Anatomy Laboratory of the Faculty of Medicine of the Universidad Catolica del Maule, Chile. The measures were recorded with an electronic caliper and samples were photographed. Regarding course of fibers of the PMFL, 76 % of the cases had a straight direction (type I) and 24 % had a rotation on its axis (type II). In addition, the fibers of PMFL were fused with PCL (66.7 %) and a lower percentage reached directly and independently to the medial femoral condyle. Averages were obtained and correlated. Thus, it was determined that there is correlation between the lateral epicondyle of the femur- lateral malleolus distance (LEF-LM) and the length of the PCL, and this same distance with de PMFL length. Also there was correlation between the length of the PCL and the length of PMFL.
