目的探讨人类膝关节交叉韧带血供系统的具体形态。方法对12侧交叉韧带健康成人尸体膝关节进行肉眼和手术显微镜下解剖、组织学断层切片观察。结果交叉韧带全段均可见血管纵行交错分布,血管口径呈节段性变化,血管口径(0.03±0.01)～(0.09±0.02)mm。交叉韧带间束中存在大量的血管及脂肪组织,其表面血管口径最大为(0.18±0.04)mm。结论交叉韧带本身拥有足够充分的血供来源,存在自我修复的可能。
Objective To investigate the specific morphology of human cruciate ligament blood supply system. Methods The coronal section of 12 knees of healthy adult with lateral cruciate ligaments was observed under microscope and under the microscope. Histological sections were observed. Results All segments of the cruciate ligament were staggered longitudinally and the vascular diameter was segmental. The diameter of the blood vessel was (0.03 ± 0.01) ~ (0.09 ± 0.02) mm. A large number of blood vessels and adipose tissue exist in the anterior cruciate ligament, and the diameter of the surface blood vessel is (0.18 ± 0.04) mm. Conclusion The cruciate ligament itself has enough blood supply, there is the possibility of self-repair.
