【摘要】 用扫描电镜观察了6例膝关节的前、后交叉韧带和髌韧带的纤维构筑形态。交叉韧带的纤维先聚集成小纤维束,再聚集成大束,纤维束呈明显的波浪状走行。相邻的纤维束由细纤维相联。束间有大小不等的间隙,是疏松结缔组织和血管存在的部位。髌韧带的纤维也是由小束到大束的排列形式,但纤维挺直无波折,纤维束间排列较密集。交叉韧带纤维的波浪状特点,可能利于存储弹性能,以便在关节运动中维持股、胫两骨关节面均匀接触受力。髌韧带与交叉韧带的纤维构筑相似,且力度大,是前交叉韧带再造术的理想供体之一。更多还原

【Abstract】 The fiber architecture of the anterior and posterior craciate h eaments and the patellar ligament were studied with the scanning electron microscopse in 6 adult knee joints. The fibers ofthe eruciatc ligamenis gerber together to form thin fiber bundles, and, further, to form thick bundles The neighboring bundles are connected by some individual fibers. The fibers appear markly the form of the rave and vave. There are some spaces between the bundles, wieh were filled with some loose connective ussue and vessels. The architectureof the patellar ligament also takes the pattern of the thin fiber bundies to tihick bundles. The bundles are gathered ckoser than that of the cruciate ligament, and lic straightly without ripplc appearce The vave-shaped fibers of the cruciate ligament can store the elasticity cnergv. wieh can mantain the articular faces of the femur and tibia to contact and press each other uniformly during the move of the knee joint. The fiber architecture of the pateliar ligament is simlier to that of the cruciate ligaments and ist strength is greater than that of them. so the patellar ligament is one of the good material for reconstruction of the anterior cruciate ligament.更多还原
