Normal articular cartilages from the weight-bearing areas of the femoral condyles of the knee joints of 11 patients (3-20 years old) and of 35 Schwarzkopf sheep (3 months to 2 years old) were studied using the electron microscope. The study has shown that the matrix of normal articular cartilage is not only composed of collagen fibrils and proteoglycans, but also contains two types of elastic system fibres. Small elastic fibres can be identified in the superficial and lower radiate zones of cartilage of man and sheep. Similar to elastic fibres in other tissues, they consist of a central amorphous core and are surrounded by aggregates of 10 nm microfibrils. Another type of elastic system fibres, oxytalan fibres, are found in the intermediate and upper radiate zones of the articular cartilage.
对11名患者（3至20岁）和35只施瓦茨科普夫绵羊（3个月至2岁）膝关节股骨髁负重区的正常关节软骨进行了电子显微镜研究。研究表明，正常关节软骨的基质不仅由胶原纤维和蛋白聚糖组成，还包含两种类型的弹性系统纤维。在人和绵羊软骨的表层和下层辐射区可识别出小弹性纤维。与其他组织中的弹性纤维相似，它们由中央无定形核心组成，并被10纳米微原纤维聚集体包围。另一种弹性系统纤维，即氧化弹力纤维，存在于关节软骨的中间和上层辐射区。
