Introduction Recent studies stressed the importance of the epiligament in ligament nutrition and healing. While ligaments of the knee joint have been the subject of extensive research, the epiligament of the medial collateral ligament has received only limited attention. The aim of our study was to present the ultrastructural morphological features of the epiligament of the medial collateral ligament in a rat knee joint. Materials and methods For the present study, we used eight eight-month-old male Wistar rats. A transmission electron microscopic study of the epiligament was conducted according to standard protocol. Results In the epiligament, we described the presence of fibroblasts with the typical features of protein-synthesizing cells, as well as fibrocytes and adipocytes. We noted an abundance of blood vessels and nerve elements. Collagen fibers were organized in multidirectional bundles. Conclusions Our findings confirm that the cells and structures of the epiligament play an important role in the nutrition and healing of the medial collateral ligament.
引言 近期研究强调了韧带系膜在韧带营养和愈合中的重要性。虽然膝关节韧带一直是广泛研究的对象，但内侧副韧带的韧带系膜仅受到有限的关注。我们研究的目的是呈现大鼠膝关节内侧副韧带韧带系膜的超微结构形态特征。材料与方法 在本研究中，我们使用了八只八个月大的雄性Wistar大鼠。根据标准方案对韧带系膜进行了透射电子显微镜研究。结果 在韧带系膜中，我们描述了具有蛋白质合成细胞典型特征的成纤维细胞，以及纤维细胞和脂肪细胞的存在。我们注意到有大量的血管和神经成分。胶原纤维呈多方向束状排列。结论 我们的研究结果证实，韧带系膜的细胞和结构在内侧副韧带的营养和愈合中起重要作用。
