Variant Anatomy of the Menisci of the Knee Joints in Men of Different Constitutional Types

The aim of study was to identify variant anatomy, age and constitutional features of both menisci of the knee joints in men.

Material and methods. The internal and external menisci of both knee joints of 84 male corpses aged 22 to 71 were investigated. The authors conducted an anthropometric study followed by the body type determination using J.M. Tanner scale. Morphometric study of the menisci of the knee joints in 84 male corpses was performed after opening the knee joint capsules with detection of the meniscus relative position and size, its shape, as well as the boundaries between their parts.

Results. The degree of physical development of men directly affects the degree of the morphometric parameters variability of the knee joint menisci. It has been demonstrated that with the enlargement of the muscular component of soma in men, the width of anterior horns of both menisci decreased and the width of the posterior horn of the medial meniscus increased. In addition, with the enlargement of the body fat component, the width of the anterior horns of both menisci and the width of the internal body increased. The wider were the shoulders and narrower was the pelvis, the wider was the anterior horn of the inner meniscus; however, the wider was the pelvis and more expressed were the signs of gyneco-morphism, the wider was the posterior horn of the medial meniscus.

Conclusion. The study results revealed that internal and external menisci of both knee joints are characterized by extensire polymorphism. Linear parameters of internal and external menisci are characterized by the statistical identity of the objects of study. There were no statistically significant differences in the morphometric parameters of the meniscus of both knee joints depending on age. At the same time constitutional features of morphometry of knee joints in men were significant.
