The purpose of this study was to compare computed tomographic (CT) arthrography with arthroscopy in the evaluation of patients with anterior knee pain. The authors studied 23 patients with patellar plicae at CT arthrography. Twenty of 21 patients presumed to have medial plicae at arthroscopy had similar findings at CT arthrography (sensitivity, 95%; specificity, 100%). However, 10 of 12 suprapatellar plicae and 11 of 11 lateral plicae seen at CT arthrography were not seen at arthroscopy. All 11 patients with a diagnosis of no or mild chondromalacia patellae at arthroscopy had similar CT arthrographic findings, whereas seven of 11 patients presumed to have moderate or severe chondromalacia patellae at arthroscopy had matching CT arthrographic results (sensitivity, 100%; specificity, 73%). CT arthrography was much more accurate in classifying plicae as thick (66%) as opposed to classifying plicae as thin (17%). The authors conclude that CT arthrography is an accurate and specific modality for distinguishing patients with anterior knee pain due to plicae from those with anterior knee pain due to differing causes.
本研究的目的是比较计算机断层扫描（CT）关节造影与关节镜检查在评估前膝痛患者中的作用。作者对23例在CT关节造影检查时有髌滑膜皱襞的患者进行了研究。在关节镜检查中推测有内侧滑膜皱襞的21例患者中，20例在CT关节造影检查时有相似表现（敏感性为95%；特异性为100%）。然而，在CT关节造影检查中发现的12例髌上滑膜皱襞中的10例以及11例外侧滑膜皱襞在关节镜检查中未被发现。在关节镜检查中诊断为无或轻度髌骨软骨软化症的所有11例患者在CT关节造影检查中有相似表现，而在关节镜检查中推测有中度或重度髌骨软骨软化症的11例患者中有7例在CT关节造影检查中有相符结果（敏感性为100%；特异性为73%）。CT关节造影在将滑膜皱襞分类为厚（66%）方面比将其分类为薄（17%）要准确得多。作者得出结论，CT关节造影是一种准确且特异的方法，可用于区分因滑膜皱襞导致前膝痛的患者与因其他不同原因导致前膝痛的患者。
