Abstract：
Objective This study aimed to compare gracilis and semitendinosus tendon graft diameters in anterior cruciate ligament (ACL) reconstruction using quadruple, quintuple, and sextuple assemblies. Another objective was to evaluate the percentage of patients in which each assembly type is possible, depending on the length of each free tendon. Methods Seventy-one patients underwent ACL reconstruction using hamstring tendons. We measured the diameters of the quadruple, quintuple, and sextuple assemblies in all patients. We recorded tendon length and graft diameter from three assembly types. Results Assembly comparison showed a statistically significant difference ( p < 0.001). In each assembly, graft diameter increased by 1 mm, a statistically significant value ( p < 0.001). In 2.8% of patients, the only potential assembly was the quadruple assembly because the free lengths of the 2 tendons removed were lower than 24 cm. The quintuple assembly was possible in 23.9% of subjects, as only the semitendinosus had a minimum length of 24 cm. The sextuple assembly was possible in 73.2% of patients because both tendons were at least 24 cm in length. Conclusion A quintuple or sextuple assembly is possible in 97.2% of cases since the final graft length of at least 8 cm is statistically significant between comparisons.
摘要：
目的本研究旨在比较在前交叉韧带（ACL）重建中使用四联法，五元组,和六元组程序集。另一个目标是评估每种组件类型可能的患者百分比，取决于每个自由肌腱的长度。方法对71例患者行绳肌肌腱重建ACL。我们测量了四元组的直径，五元组,和所有患者的六元组集合。我们记录了三种组装类型的肌腱长度和移植物直径。结果装配比较显示出统计学上的显著差异(p<0.001)。在每个组件中，移植物直径增加1毫米，有统计学意义的值(p<0.001)。在2.8%的患者中，唯一潜在的组装是四重组装，因为移除的2根肌腱的自由长度低于24厘米。23.9%的受试者可以进行五重组装，因为只有半腱肌的最小长度为24厘米。73.2％的患者可以进行六组组装，因为两个肌腱的长度至少为24厘米。结论在97.2％的病例中，五组或六组组装是可能的，因为在比较之间，至少8cm的最终移植物长度具有统计学意义。
