Measurement of the size of the suprapatellar pouch of the knee appears to be a simple, useful, objective, and reproducible assessment of synovitis of the knee. Changes in the apparent size of the suprapatellar pouch have been shown to correlate closely with the volume of synovial fluid aspirated from the knee and with changes in circumferential measurements. Aspiration of 20 ml of fluid will produce a change in size significant at the 1% level. Lateral xeroradiographs were used in this study, as soft-tissue planes are more closely defined on xeroradiographs than on standard radiographs.
测量膝关节髌上囊大小似乎是一种对膝关节滑膜炎进行的简单、有用、客观且可重复的评估方法。髌上囊外观大小的变化已被证明与从膝关节抽出的滑液量以及周径测量的变化密切相关。抽出20毫升液体将产生在1%水平上具有显著意义的大小变化。本研究使用了外侧干板X线片，因为在干板X线片上软组织平面比在标准X线片上更清晰。
