Femoral condylar cartilage abnormalities were evaluated in patients treated with total knee arthroplasty, and real-time ultrasonic images were correlated with the abnormalities seen in the corresponding gross pathologic specimens. Subjective impressions of abnormalities on the images recorded on film correlated well with pathologic findings. Thickness measurements were easily made in normal images but proved difficult at sites of cartilage damage where the cartilage-bone and cartilage-soft-tissue interfaces became less clear. This study suggests that with further technologic refinement, this technique may provide a rapid and cost-effective method of assessing the integrity of femoral condylar cartilage.
对接受全膝关节置换术的患者的股骨髁软骨异常情况进行了评估，并将实时超声图像与相应大体病理标本中所见的异常情况进行了关联。胶片记录图像上对异常情况的主观印象与病理结果相关性良好。在正常图像中很容易进行厚度测量，但在软骨损伤部位，软骨-骨和软骨-软组织界面变得不那么清晰时，测量就变得困难。这项研究表明，随着技术的进一步完善，该技术可能会提供一种快速且经济高效的评估股骨髁软骨完整性的方法。
