MURLIMANJU, B. V et al. Morphometric Analysis of the Menisci of the Knee Joint in South Indian Human Fetuses. Int. J. Morphol. [online]. 2010, vol.28, n.4, pp.1167-1171. ISSN 0717-9502.

The morphometrical data related to the menisci of the adults have been reported by few authors and that of the fetuses have not been reported. The aims of the present study were to analyse the external circumference thickness, the width, peripheral and inner border lengths, and the distance between anterior and posterior horns of the fetal menisci and to compare the meniscal dimensions with that of the adult meniscal parameters which are available in the literature. The menisci from 106 knee joints of the formalin fixed South Indian fetuses which were obtained from the anatomy department were analysed. The fetuses which had musculoskeletal anomalies were excluded from the study. A vernier caliper of 0.02 mm accuracy and a non elastic cotton thread were used for the morphometry. After comparing the meniscal dimensions of the present study with the adult meniscus parameters, we established that the fetal parameters of the meniscus are entirely different from the adults. These differences are may be due to the mesenchymal differentiation or variability of the vasculature early in embryonic life. We believe that our study will provide support to the fetal anatomy, concerning surgical procedures and arthroscopy of the knee joint. Since the morphometric studies of the fetal menisci are not reported, this study may be considered new and needs to be studied further with different groups of fetuses from various stages of intrauterine development. This study is important not only for orthopedic surgeons, but also for morphologists and embryologists.
