目的：观察低强度脉冲超声对兔髌骨-髌腱连接点愈合的影响。方法：60只成熟雌性新西兰大白兔按同一标准行髌骨部分切除术，术后按治疗方式随机分成对照组和治疗组。对照组术后给予安慰治疗，治疗组术后3d~6周给予低强度脉冲超声治疗。分别于术后6，12，18周时处死动物并获取髌骨-髌腱复合体标本，标本常规脱钙后做成切片行H&E染色与番红素染色用于组织学观察。利用SANO Microscope Partner显微图像测量软件进行组织学分析，比较两组纤维软骨层厚度与灰度值差异。结果：术后6，12和18周时，治疗组的纤维软骨层厚度明显大于对照(P<0.01)，灰度值明显小于对照(P<0.01)。结论：低强度脉冲超声可以促进兔髌骨-髌腱连接点纤维软骨层的愈合。

Objective:To analyse the effect of low intensity pulsed ultrasound stimulation (LIPUS) on accelerating the ifbrocartilage layer repair of patella-patellar tendon junction. <br> Methods:A total of 60 mature female New Zealand white rabbits undergoing standard partial patellectomy were divided into 2 groups randomly. hTe control group was given comfort threatment and the treatment group was given LIPUS treatment starting from day 3 to the end of week 6 postoperatively. hTe scheduled time points of animal euthanization would be at week 6, week 12 and week 18 postoperatively. hTe patella-patellar tendon (PPT) complex would be harvested and cut into sections atfer decalciifcation for H&E staining, Safranine o/fast green staining. hTe thickness and gray value of ifbrocartilage layer were analyzed by SANO Microscope Partner image analyzer. <br> Results:At week 6, week 12 and week 18 postoperatively, the ifbrocartilage layer in the treatment group was significantly thicker than that in the control group (P<0.01), and the gray value of ifbrocartilage layer was signiifcantly smaller than that in the control group (P<0.01). <br> Conclusion:LIPUS helps to accelerate the fibrocartilage layer repair of patella-patellar tendon junction in rabbit models.
