Morphological and historogical examination of the injured discoid menisci were investigated by means of scanning electron microscopy. The surface of the meniscus was covered with fine collagen fibrils which showed randamly arranged network. The substance of the meniscus consisted of the layers of collagen fiber bundles arranged horizontally from anterior to posterior segment. There were few vertically oriented fibers. This structure appears to play an important role in producing horizontal tear of the discoid meniscus in addition to the degeneration of the central portion and mechanical stress such as direct compression, anteroposterior and rotatory strain.
