目标:跟腱(AT)软骨层生长的组织学差异,股四头肌腱(QT),髌腱(PT),前交叉韧带(ACL)的插入尚不清楚。因此,本研究旨在探讨AT软骨层生长的差异,QT,PT,和ACL插入。材料与方法:采用48只雄性日本大白兔。在不同阶段(第1天和第1、2、4、6、8、12和24周)对6只动物实施安乐死。SafraninO-染色糖胺聚糖(GAG)生产区,软骨细胞计数,和插入宽度进行了调查。结果:双向方差分析(ANOVA)显示,所有参数的时间和插入的主要影响均存在显着差异。此外,时间×插入交互作用显著。多重比较显示ACL插入和所有其他变量之间存在显著差异;然而,QT的GAG生产面积没有显著差异,PT,和AT插入。AT插入与所有其他组明显不同;然而,ACL的软骨细胞数量和插入宽度没有显着差异,QT,和PT插入。结论:AT之间的软骨层生长不同,QT,PT,和ACL插入。插入之间的差异也可能是由于其结构的差异,地点,和机械环境。
Objectives: Histological differences in cartilage layer growth in Achilles tendon (AT), quadriceps tendon (QT), patellar tendon (PT), and anterior cruciate ligament (ACL)
insertion are unclear. Therefore, this study aimed to investigate the differences in cartilage layer growth in AT, QT, PT, and ACL insertions. Materials and Methods: Forty-eight male Japanese white rabbits were used. Six animals were euthanized at different stages (day 1 and 1, 2, 4, 6, 8, 12, and 24 weeks). Safranin O-stained glycosaminoglycan (GAG) production area, chondrocyte count, and
insertion width were investigated. Results: A two-way analysis of variance (ANOVA) revealed a significant difference in the main effects of time and
insertion for all parameters. In addition, the time ×
insertion interaction was significant. Multiple comparisons showed a significant difference between the ACL
insertion and all other variables; however, the GAG production area was not significantly different for the QT, PT, and AT insertions. AT insertions were significantly different from all other groups; however, the number of chondrocytes and insertion width were not significantly different for ACL, QT, and PT insertions. Conclusion: Cartilage layer growth differed between the AT, QT, PT, and ACL insertions. The differences between the insertions may also be due to the differences in their structures, locations, and mechanical environments.
