摘　　要：目的探讨应用高频超声测量前交叉韧带(anterior cruciate ligament,ACL)厚径的可行性及准确性。方法选择2015-01至2015-09现役男性军人健康志愿者30名,分别应用高频超声及MRI测量右膝关节ACL胫骨止点端厚径。对比分析两名不同医师应用高频超声测量ACL厚径的结果,再对比分析应用高频超声及MRI测量ACL厚径的结果。结果两名医师应用高频超声测量ACL厚径具有较好的一致性及可重复性,其组内相关系数ICC=0.934,95%区间为(0.867,0.968);使用Bland-Altman法分析:两位医师测量ACL厚径差值(mm)均值为-0.04,95%区间为(-0.55,0.47)。应用高频超声与MRI测量ACL厚径具有较好的一致性,提示两种方式是可替代的;其组内相关系数ICC=0.914,95%区间为(0.822,0.959);使用Bland-Altman法分析:应用高频超声与MRI测量ACL厚径差值(mm)均值为0.04,95%区间为(-0.62,0.70)。结论高频超声可作为测量膝关节ACL厚径的常规方法。Objective To test if the thickness of normal anterior cruciate ligament（ ACL） can be measured by high frequency ultrasound（ US）. Methods The thickness of ACL near tibial insertion site was measured by US and magnetic resonance imaging（ MRI） in 30 normal right knees of young male soldiers. The thickness of ACL near tibial insertion site which was measured by two different radiologists by US were compared and analysed. The thickness of ACL near tibial insertion site which was measured by US and MRI were compared and analysed. Results The intraclass correlation coefficient for these 2 radiologists was 0. 934（ 95% CI： 0. 867 to0. 968） and Bland Altman plot showed that the mean difference was- 0. 04（ 95% CI：- 0. 55 to 0. 47）,indicating a very strong agreement between these 2 radiologists in measuring the thickness of ACL by US. The intraclass correlation coefficient for US and MRI was 0. 914（ 95% CI： 0. 822 to 0. 959） and Bland Altman plot showed the mean difference was 0. 04（ 95% CI：- 0. 62 to 0. 70）,indicating a very strong agreement between these 2 methods in measuring the thickness of ACL. Conclusions High frequency ultrasound can be used as a conventional method for measuring the thickness of ACL.
