磁共振成像（MRI）通常是评估膝关节软骨和软骨下骨病变的首选方法。已经有一些使用实时弹性超声成像（RTE）的软骨成像研究，近年来其重要性和使用范围都有所增加。本尸体研究的目的是评估一种新的诊断方法结合USG和RTE的有效性，并与关节镜一起进行关节内检查。共检查了12个新鲜的未配对的人膝关节。使用标准前内侧和前外侧关节镜入路展开腹腔镜超声换能器。使用镶嵌成形术工具在看起来健康的软骨区域检查医源性缺损，并使用RTE测量这些区域的应变。病变股骨软骨区的中位应变值显著高于正常软骨区（分别为1.23 [0.71-2.24] vs. 0.01 [0.01-0.01]，P = 0.002）。使用RTE的软骨关节镜研究可以为骨科医生提供指导，并且可以普及关节内探针的使用。临床解剖学32：99-104，2019年。(c)2018 Wiley Periodicals，Inc.
Magnetic resonance imaging (MRI) is generally the preferred method for assessing lesions of the knee cartilage and subchondral bone. There have been a few cartilage imaging studies using real-time elastosonography (RTE), which has increased in importance and range of use in recent years. The aim of this cadaveric study was to assess the efficacy of a new diagnostic method combining USG and RTE and also to perform intra-articular examinations together with arthroscopy. A total of 12 fresh unpaired human knees were examined. The laparoscopic ultrasound transducer was deployed using standard anteromedial and anterolateral arthroscopic portals. Iatrogenic defects were examined using mosaicplasty tools in healthy-looking areas of cartilage, and strain in those areas was measured using RTE. The median strain value of the pathological femoral cartilage region was significantly higher than that of the normal cartilage region (1.23 [0.71-2.24] vs. 0.01 [0.01-0.01], P = 0.002, respectively). Arthroscopic study of cartilage using RTE can be a guide for orthopedic surgeons and use of intra-articular probes could be universalized. Clin. Anat. 32:99-104, 2019. (c) 2018 Wiley Periodicals, Inc.
