The specimens from 19 femoral heads with various abnormalities are observed with scanning electron microscopy, comparing with light microscopic findings. Villi and plica appearance implies the fibrillated surface of degenerated cartilage with fibrous tissue proliferation. Beside these findings, craters with their associated undulations of concentric circles or guitar-shaped figures are visualized in the areas histologically showing the exposed cartilage of the deep zone. The undulations are correspondent to the fine clefts of the shredding surface. From the observations reported here, the existence of the lamellar system around the chondrocyte lacuna is proposed in the deep matrix of the articular cartilage.
对19个具有各种异常的股骨头标本进行扫描电子显微镜观察，并与光学显微镜观察结果进行比较。绒毛和皱襞外观提示退变软骨表面呈纤维状，伴有纤维组织增生。除了这些发现外，在组织学上显示深层区域软骨暴露的区域可见伴有同心圆或吉他形图案起伏的凹坑。这些起伏与撕裂表面的细微裂缝相对应。根据此处报道的观察结果，提出在关节软骨深层基质中软骨细胞陷窝周围存在板层系统。
