| 目的：探讨股四头肌腱的生物力学特性，为其能否应用于临床前交叉韧带(ACL)重建提供实验依据。方法：取32 例新鲜尸体
的1cm 宽股四头肌腱，按其解剖结构分为两束：股直肌、股内、外侧肌腱合为A 束，股中间肌腱为B 束，用游标卡尺测量两束的宽
度及厚度，然后将两束置于电子万能试验机上分别测其生物力学指标。结果：A 束厚度为4.39±1.72mm,宽度为8.19±1.18mm，生
物力学强度为685.67±227.09N，抗拉强度为17.00±3.48Mpa；B 束厚度为3.06±1.47mm，宽度为7.10±2.03mm，生物力学强度
为435.04±205.80N，抗拉强度为13.16±4.02Mpa。A 束生物力学强度与ACL 比较，差异有统计学意义（p<0.05)；B 束生物力学强
度与ACL 比较，差异有统计学意义（p<0.05）。结论：股四头肌腱的生物力学性能不能满足ACL 双束重建的要求，其在临床上应用
于ACL 双束重建的价值有待于进一步的深入研究。 |

| Objective: To investigate the biomechanics of the quadriceps tendon and to provide theoretical basis for double-bundle
reconstruction of anterior cruciate ligament(ACL). Methods: 32 quadriceps tendons (width 1cm) taken from fresh cadaver were dissected
into 2 bundles according to the anatomy, one bundle including rectus femoris, vastus medialis and vastus lateralis was named A bundle
and the other was named B bundle. The width and thickness of the A and B bundle were detected respectively with a Vernier caliper and
the biomechanics were determined by WDW-30 election universal testing machine. Results: The thickness, width, ultimate load and ultimate
tensile strength of bundle A were 4.39±1.72mm, 8.19±1.18mm, 685.67±227.09 N and 17.00±3.48 Mpa respectively, while for
bundle B,which were 3.06±1.47 mm, 7.10±2.03mm, 435.04±205.80 N and 13.16±4.02 Mpa. There was difference between bundle
A and the ACL (p<0.05). Conclusion: The ultimate load of bundle A was much lower than the the ACL and bundle Bwas also lower than
the ACL. |
