摘　　要：Objective:While age has been recognized as a noteworthy factor in preoperative graft selection,the correlation between age and hamstring autograft diameter has been the subject of continued debate within the scientific community.This study aimed to explore the correlation between the diameter of autologous tendon grafts and age in anterior cruciate ligament reconstruction(ACLR).Methods:A retrospective review of 388 patients who underwent arthroscopic ACLR with hamstring autografts was performed.Patients were grouped by age to analyze differences in hamstring autograft dia-meter and tendon cross-sectional area(CSA).We explored the correlations between age and graft diameter and between age and the CSA of the popliteal tendon while controlling for the influence of other pertinent variables.Results:Compared with female patients,male patients presented significantly greater autograft diameters and hamstring tendon CSAs(P<0.05).Notably,graft diameter and hamstring tendon CSA varied significantly across different age groups(P<0.05);pa-tients aged>32 years were substantially more likely to have a graft diameter exceeding 8 mm and a CSA surpassing 18.5 mm2 than their≤32-year-old counterparts were(P<0.05).Conclusion:This study revealed that graft diameter varies across different age groups,with age independently influencing graft diameter.目的:年龄是术者行前交叉韧带重建术中移植物选择需要考虑的因素之一。年龄与自体肌腱移植物直径之间是否具有相关性一直具有争议。本研究旨在探究前交叉韧带重建中自体肌腱移植物直径与年龄的相关性,并探究其他相关的影响因素。方法:回顾性研究了388例采用自体腘绳肌腱移植物进行关节镜下前交叉韧带重建的患者。将患者根据年龄分组,分析不同年龄段患者的自体肌腱移植物直径及腘绳肌腱横截面积的差异。在使用倾向得分匹配控制其他相关变量的情况下分别探究年龄与移植物直径、年龄与腘绳肌腱横截面积之间的相关性。结果:男性患者的自体移植物直径和腘绳肌腱横截面积均显著高于女性(P<0.05)。不同年龄组中患者的移植物直径和腘绳肌腱横截面积均具有显著差异(P<0.05);与年龄≤32岁的患者相比,年龄>32岁的患者自体肌腱移植物直径≥8 mm,腘绳肌腱横截面积≥18.5 mm2的可能性更大(P<0.05)。结论:不同年龄段患者的移植物直径是有差异的,年龄是移植物直径的独立影响因素,年龄较小的患者在行前交叉韧带重建术时需考虑编织的自体肌腱直径不足的情况。
