The knowledge of the meniscofemoral ligaments (MFL) is of great importance to the anatomy and surgical clinic. In order to conduct an analysis of their frequency and biometry in Chilean individuals, 30 knees of corpses of adult individuals, sex unknown, fixed in 10 % formaldehyde and belonging to the Laboratory of Anatomy, Faculty of Medicine of the Universidad Católica del Maule, Chile. Using a digital caliper, measurements of length, width and the thickness to different levels were recorded. All the samples studied were photographed. Regarding frequency, PMFL occurred in 21 cases (70 %) and AMFL in 13 (43.4 %). The average length of AMFL was 29.04±2.66 mm and the PMFL 27.46±3.08 mm; the proximal width of the AMFL was 9.88±4.34 mm and the PMFL of 6.55±2.14 mm and the average thickness of the AMFL was 1.19±0.47 mm and the PMFL of 1.8±0.68 mm. Other measurements are shown in the text. The obtained results are a contribution to the knowledge of ligaments of the knee joint in our population.
