The purpose of this study was to assess ultrasonographic image changes in the patellar tendon after removal of its central one third for anterior cruciate ligament reconstruction. Fourteen patellar tendons in 14 patients were assessed preoperatively and at 2 weeks, 4 weeks, 2 months, 6 months, and 12 months postoperatively. With time, the entire donor tendon became enlarged, hypoechoic, and inhomogeneous compared with the presurgical state. Tendons enlarged maximally in anteroposterior thickness by 2 months and then began to diminish, remaining two times their original anteroposterior thickness by 12 months and never returning to their preoperative appearance. The margins of the defect became indistinct over time. In the donor patellar tendon, abnormal echogenicity was profound and persisted up to 1 year after surgery. Ultrasonographic imaging has the ability to evaluate the postoperative patellar tendon over time and to monitor the normal changes seen with healing.
本研究的目的是评估在取髌腱中央三分之一用于前交叉韧带重建后，髌腱的超声图像变化。对14例患者的14条髌腱在术前以及术后2周、4周、2个月、6个月和12个月进行评估。随着时间推移，与术前状态相比，整个供体肌腱变得增粗、低回声且不均匀。肌腱前后径在2个月时增大到最大，然后开始减小，到12个月时仍为其原始前后径的两倍，且从未恢复到术前外观。随着时间的推移，缺损边缘变得模糊不清。在供体髌腱中，异常回声明显，且在术后长达1年持续存在。超声成像能够随时间评估术后髌腱情况，并监测愈合过程中出现的正常变化。
