确定了来自三个年轻人类供体膝盖的前十字韧带和后十字韧带（ACL、PCL）、外侧副韧带（LCL）和髌腱（PT）的骨-束-骨单位的束材料特性。从每个组织中分离出具有完整骨端的束组，并在 37°C 的盐水浴中以高应变率失效。 C. 在测试的每个膝盖中，髌腱的负载相关材料特性（线性模量、最大应力和最大应力的能量密度）明显大于十字韧带和副韧带的相应值。来自同一膝盖不同韧带的束的机械行为彼此相似。此外，所检查的四种组织类型中记录的最大应变不存在显着差异。所提出的结果对韧带损伤的研究具有重要意义。它们在合成和生物韧带置换的设计和使用以及组织和整个膝盖建模中也很重要。
The fascicle material properties in bone-fascicle-bone units were determined for the anterior and posterior cruciate ligaments (ACL, PCL), the lateral collateral ligament (LCL) and the patellar tendon (PT) from three young human donor knees. Groups of fascicles from each tissue were isolated with intact bone ends and failed at a high strain rate in a saline bath at 37.degree. C. In each knee tested the load related material properties (linear modulus, maximum stress and energy density to maximum stress) for the patellar tendon were significantly larger than corresponding values for the cruciate and collateral ligaments. Bundles from different ligaments in the same knee were similar to each other in their mechanical behavior. In addition, no significant differences were present in the maximum strains recorded for any of the four tissue types examined. The results presented have implications in studies of ligament injury. They are also important in the design and use of synthetic and biological ligament replacement and in tissue and whole knee modeling.
