We evaluated the ability of high-resolution, real-time sonography to identify and characterize artificially produced lesions in the menisci in human cadaveric knee specimens. In total, 20 lesions created in 10 specimens from five knees were prepared and examined sonographically. Four different types of lesions were created: eight vertical concentric tears, four horizontal tears, four vertical radial tears, and four complex lesions including displaced or amputated meniscal edges. All 20 (100%) of the lesions were visualized sonographically. The vertical concentric tears were the easiest to locate and identify, and appeared as highly echogenic lines in the menisci. Tears of this type as small as 2 mm could be visualized. The vertical radial tears were the most difficult to visualize, and no lesions of this type smaller than 5 mm could be seen. Our study shows that under optimal experimental conditions, sonography is capable of reliably demonstrating even small meniscal tears. On this basis, we believe that further clinical studies of the efficacy of meniscal sonography are both reasonable and necessary.
我们评估了高分辨率实时超声检查在识别和表征人体尸体膝关节标本半月板人工制造损伤方面的能力。总共在来自五个膝关节的10个标本中制造了20处损伤,并进行了超声检查。制造了四种不同类型的损伤:八处垂直同心撕裂、四处水平撕裂、四处垂直放射状撕裂以及四处复杂损伤,包括半月板边缘移位或截断。所有20处(100%)损伤均在超声检查中显影。垂直同心撕裂最容易定位和识别,在半月板中表现为高回声线。小至2毫米的此类撕裂均可显影。垂直放射状撕裂最难显影,小于5毫米的此类损伤均未被发现。我们的研究表明,在最佳实验条件下,超声检查能够可靠地显示即使是小的半月板撕裂。在此基础上,我们认为对半月板超声检查疗效进行进一步临床研究是合理且必要的。
