Abstract：
OBJECTIVE: To compare the biomechanical properties of lateral femoro-fabella ligament suture (FFLS) and lateral suture with a bone anchor suture (BAS) for management of feline cranial cruciate ligament disease.
METHODS: 12 femurs from 6 mature cat cadavers.
METHODS: The samples were collected from April to June 2023. The specimens had an FFLS and, subsequently, BAS placed and were positioned into a biomechanical testing machine, preloaded from 5 N to 15 N for 100 cycles, and subsequently, a load to suture failure was applied. The displacement at 5 N and 15 N, the total precycle displacement (millimeters), the force at 3 mm displacement and at failure (newtons), the displacement at failure (millimeters), and the stiffness to failure (Newton:millimiter) were recorded. Nonparametric Wilcoxon signed-rank tests were used to compare data between the 2 groups.
RESULTS: The displacement at 5 N and 15 N and the total precycle displacement were significantly higher in the FFLS group compared to the BAS group. Additionally, the FFLS group results showed less consistent displacement and marked variability. The force (newtons) at 3 mm displacement was higher in the BAS group. There was no significant difference in force and no significant difference in displacement at failure between the 2 groups. However, the stiffness to failure (N/mm) was significantly higher in the BAS group.
CONCLUSIONS: BAS represented a more stable and reliable femur attachment for extracapsular suture in cats.
CONCLUSIONS: To demonstrate the stability and reliability between BAS and FFLS and influence implant selection in the treatment of cranial cruciate ligament rupture in cats with evaluation of biomechanical properties.

摘要：
目的：比较股外侧韧带缝线（FFLS）和外侧缝线与骨锚钉缝线（BAS）治疗猫颅交叉韧带疾病的生物力学特性。
方法：来自6只成熟猫尸体的12只股骨。
方法：样品收集时间为2023年4月至6月。标本有FFLS，随后,BAS放置并放置在生物力学试验机中，从5N到15N预加载100个循环，随后,对缝合失败施加负荷。5N和15N时的位移,总的预循环位移(毫米)，3mm位移和失效时的力（牛顿），失效时的位移（毫米），并记录破坏刚度（牛顿：millimer）。使用非参数Wilcoxon符号秩检验比较两组之间的数据。
结果：与BAS组相比，FFLS组的5N和15N处的位移和总的前周期位移明显更高。此外,FFLS组结果显示位移不一致,变异性显著.在BAS组中,在3mm位移下的力(牛顿)更高。两组之间的力没有显着差异，破坏时的位移也没有显着差异。然而,BAS组的破坏刚度(N/mm)显著较高.
结论：BAS代表了用于猫的囊外缝合的更稳定和可靠的股骨附着。
结论：为了证明BAS和FFLS之间的稳定性和可靠性，并通过生物力学特性评估来评估猫的颅骨交叉韧带破裂治疗中的植入物选择。
