Abstract

TORREZ, J.C; OLAVE, M. C; TORREZ, H. F  and  OLAVE, E. Biometric Characteristics of Knee Meniscus in Chilean Individuals. Int. J. Morphol. [online]. 2011, vol.29, n.3, pp.1007-1011. ISSN 0717-9502.  http://dx.doi.org/10.4067/S0717-95022011000300058.

The menisci are cartilage plates that help to expand low concavity of articular surfaces of the tibia to receive the convex femoral condyles. They satisfy functional needs, as has been demonstrated with reconstitution following total excision. In order to provide biometric data on its characteristics, anteroposterior diameters, transverse and thickness at various levels were recorded to complement anatomy of the same in our population. We conducted a study in 20 menisci, 10 lateral and 10 medial from adult Chilean cadaver specimens, in the Anatomy Laboratory, Universidad de La Frontera. The samples were prepared to carry out various measurements cleaning the fibrous structures associated with these menisci. Recordings were registered with a Mitutoyo digital caliper with a 0.05 mm accuracy. Lateral meniscus showed an average anteroposterior distance between horns of 31.7 mm, meniscal opening was 11.5 mm, distance between anterior- posterior borders of the anterior horn was 10.9 mm, of the posterior horn 10.9 mm. The peripheral thickness of its anterior part was 3.8 mm, of its posterior part was 6.1 mm and in its middle section 5.9 mm.The medial meniscus had an average anteroposterior distance between anterior an posterior horn of 43.2 mm. Meniscal opening was 26.1 mm, distance between anterior and posterior borders of the anterior horn was 0.2 mm, in its posterior horn 13.5 mm, peripheral thickness in its anterior part was 4.5 mm, its posterior part was 6.0 mm and at the middle section of the meniscus was 5.5 mm. The data provided will complement anatomy of the menisci in Chilean population.
