用扫描电镜观察了关节软骨表面胶原纤维的来源和结构。冷冻断裂用于在三个平面中创建正交断裂表面。起源于径向区的纤维可以追踪到表面，在那里它们在一个共同的方向上变平和重叠。来自骨膜的粗纤维也进入表面，但显然在那里结束，没有进入桡骨区。切向纤维被一层致密的、分离的小原纤维覆盖。本宁霍夫提出的模型的基本方面得到了这些研究结果的支持。
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.
