Abstract

In five patients undergoing magnetic resonance imaging of the knee after athletic injuries, the authors identified a vacuum phenomenon that simulated medial meniscal or joint compartment cartilaginous abnormality. A cadaveric knee was injected with air, and the findings were re-created. The presence of air or gas between the articular surfaces of the tibia and femur can simulate meniscal or cartilaginous injury.

摘要

在5例运动损伤后接受膝关节磁共振成像检查的患者中，作者发现了一种模拟内侧半月板或关节腔软骨异常的真空现象。向一具尸体膝关节注入空气后，重现了这些发现。胫骨和股骨关节面之间存在空气或气体可模拟半月板或软骨损伤。
