The origin and structure of collagen fibres in the surface of articular cartilage were studied using SEM. Cryofracture was used to create orthogonal fracture surfaces in three planes. Fibres which originated in the radial zone could be traced into the surface where they flattened and overlapped in a common direction. Thick fibres from the periosteum ran into the surface as well, but apparently ended there and did not enter the radial zone. The tangential fibres were covered by a dense, separate layer of small fibrils. The fundamental aspects of the model proposed by Benninghoff are supported by these findings.
利用扫描电子显微镜（SEM）研究了关节软骨表面胶原纤维的起源和结构。采用冷冻断裂技术在三个平面上创建正交断裂面。起源于放射状区域的纤维可以追踪到表面，在那里它们变平并沿共同方向重叠。来自骨膜的粗纤维也延伸到表面，但显然在那里终止，没有进入放射状区域。切线纤维被一层致密、独立的小纤维覆盖。这些发现支持了本宁霍夫提出的模型的基本方面。
