PURPOSE
To evaluate the value of ultrasound (US) in assessing joint inflammation in patients with juvenile rheumatoid arthritis (JRA) of the knee.
MATERIALS AND METHODS
US scans obtained in 36 children (mean age, 8 years) with JRA of the knee were compared with those obtained in 30 healthy children.
RESULTS
Changes in synovial membrane (synovial thickness), presence of fluid in the suprapatellar bursa, and alterations in the contour (blurring) of the articular cartilage showed statistically significant differences between JRA patients and control subjects. US was more sensitive than physical examination for detecting a minimal amount of intra-articular fluid in 21% of JRA-affected knees with no clinical evidence of active disease.
CONCLUSION
US is a simple, rapid, inexpensive, and accurate method for assessing joint inflammation in patients with JRA of the knee.
目的
评估超声（US）在评估幼年类风湿关节炎（JRA）膝关节患者关节炎症中的价值。
材料与方法
将36例膝关节JRA患儿（平均年龄8岁）的超声扫描结果与30例健康儿童的超声扫描结果进行比较。
结果
JRA患者与对照组在滑膜变化（滑膜厚度）、髌上囊内液体的存在以及关节软骨轮廓改变（模糊）方面存在统计学显著差异。在21%无活动性疾病临床证据的JRA受累膝关节中，超声检测少量关节内液体比体格检查更敏感。
结论
超声是一种评估JRA膝关节患者关节炎症的简单、快速、廉价且准确的方法。
