| 2 | Light and electron microscopic study of the medial collateral ligament epiligament tissue in human knees显示文摘AIM To examine the normal morphology of the epiligament tissue of the knee medial collateral ligament(MCL) in humans. METHODS Several samples of the mid-substance of the MCL of the knee joint from 7 fresh human cadavers(3 females and 4 males) were taken. Examination of the epiligament tissue was conducted by light microscopy and photomicrography on semi-thin sections of formalin fixed paraffin-embedded blocks that were routinely stained with haematoxylin and eosin, Mallory stain and Van Gieson's stain. Electron microscopy of the epiligament tissue was performed on ultra-thin sections incubated in 1% osmium tetroxide and contrasted with 2.5% uranyl acetate, lead nitrate, and sodium citrate.RESULTS The current light microscopic study demonstrated that the epiligament of the MCL consisted of fibroblasts, fibrocytes, adipocytes, neuro-vascular bundles and numerous multidirectional collagen fibers. In contrast, the ligament body was poorly vascularised, composed of hypo-cellular fascicles which were formed of longitudinal groups of collagen fibers. Moreover, most of the vessels of the epiligament-ligament complex were situated in the epiligament tissue. The electron microscopic study revealed fibroblasts with various shapes in the epiligament substance. All of them had the ultrastructural characteristics of active cells with large nuclei, well developed rough endoplasmic reticulum, multiple ribosomes, poorly developed Golgi apparatus, elliptical mitochondria and oval lysosomes. The electron microscopy also confirmed the presence of adipocytes, mast cells, myelinated and unmyelinated nerve fibers and chaotically oriented collagen fibers.CONCLUSION Significant differences exist between the normal structure of the ligament and the epiligament whose morphology and function is to be studied further. | Georgi P Georgiev Alexandar Iliev Georgi Kotov Plamen Kinov Svetoslav Slavchev Boycho Landzhov | 2017 | World Journal of Orthopedics2017，8，5： | 1 |
