Abstract：
UNASSIGNED: During the initial stages of rehabilitation after anterior cruciate ligament (ACL) surgery, a pivotal role is played in ensuring effective recuperation and averting complications. An often-employed strategy to tackle ACL laxity during this period involves the incorporation of synthetic materials for reinforcement. The objective of this study is to compare the effectiveness of conventional suture tape and multiple high-strength sutures as augmentation techniques for ACL repair.
UNASSIGNED: Ten preserved cadaveric knees embalmed using the Thiel method were segregated into two groups, each containing five knees. In one group, traditional suture tape was employed for augmentation, while the other group utilized multiple high-strength sutures. Each knee underwent a cyclic load of 1000 sine wave cycles, succeeded by an axial distraction load until failure ensued. The resultant displacement and ultimate load at failure were assessed to contrast the efficacy of the two augmentation techniques.
UNASSIGNED: The group utilizing multiple high-strength sutures exhibited a significantly higher load to failure at time-zero (1690.7 N) compared to the suture tape group (987.6 N) (P = .003). Furthermore, the multiple high-strength sutures group demonstrated significantly reduced displacement after 1000 cyclic loads (6.6 mm) in comparison to the suture tape group (16.3 mm) (P < .001).
UNASSIGNED: Multiple high-strength sutures show better biomechanical properties for the augmentation of ACL repair at time-zero. Both suture tape and multiple high-strength sutures had ultimate load-to-failure values higher than the natural ACL loads. Therefore, these substances might serve as augmentation options to prevent the ACL\'s gradual elongation, a critical concern particularly in the initial stages of rehabilitation.

摘要：
■在前交叉韧带（ACL）手术后康复的初始阶段，在确保有效康复和避免并发症方面发挥了关键作用。在此期间，解决ACL松弛问题的一种常用策略涉及结合合成材料进行增强。这项研究的目的是比较常规缝合带和多种高强度缝合线作为ACL修复增强技术的有效性。
■将使用Thiel方法进行防腐的十个保存的尸体膝盖分为两组，每个包含五个膝盖。在一组中,传统的缝合带被用于增强，而另一组则使用了多条高强度缝线。每个膝盖承受1000个正弦波周期的循环载荷，通过轴向牵引载荷成功，直到随后发生故障。评估了破坏时产生的位移和极限载荷，以对比两种增强技术的功效。
■与缝合带组（987.6N）相比，使用多个高强度缝合线的组在时间零点（1690.7N）表现出明显更高的失效负荷（P=.003）。此外，与缝合带组(16.3mm)相比,多次高强度缝线组1000次循环负荷(6.6mm)后的位移显著减少(P<.001).
■多根高强度缝合线显示出更好的生物力学特性，可在时间零点增强ACL修复。缝合胶带和多根高强度缝合线的极限失效载荷值均高于自然ACL载荷。因此,这些物质可能作为增强选项，以防止ACL的逐渐延长，特别是在康复的初始阶段。
