Scanning electron microscopic studies revealed numerous humps on the surface or articular cartilage from a 7 years old boy and from 1 month old rabbits. This shows that the surface topography of articular cartilage in young individuals is different from that of older individuals (human and rabbit) where the surface is beset by numerous pits. In 2 months old rabbits an intermediate situation was witnessed, for both shallow pits and occasional humps were present. Ridges and undulations were not seen on the articular surface of the 7 years old boy, except near the cut edge of the specimen. They were, however, found on air-dried specimens of 1 month old rabbit cartilage, but were absent from specimens dried by the critical-point method. The collective evidence supports the idea that ridges and undulations are not a constant feature of the normal articular surface, but that such features are artefactual, a typical or pathological.
扫描电子显微镜研究显示，一名7岁男孩和1月龄兔子的关节软骨表面有许多隆起。这表明，年轻个体关节软骨的表面形貌与年长个体（人类和兔子）不同，后者的表面布满了许多凹坑。在2月龄兔子中观察到一种中间情况，既有浅凹坑，也有偶尔的隆起。除了标本的切割边缘附近，在7岁男孩的关节表面未发现嵴和起伏。然而，在1月龄兔子软骨的空气干燥标本上发现了它们，但在临界点干燥法制备的标本上则没有。这些证据共同支持了这样一种观点，即嵴和起伏不是正常关节表面的恒定特征，而是人为的、典型的或病理性的特征。
