The purpose of this study was to define the sonographic appearance and echogenicity of the normal posterior cruciate ligament (PCL). We examined the PCL of five amputated specimens and five normal subjects using a 10- megahertz linear-array transducer. One K-wire was inserted into the substance of the PCL of the amputated knee specimens to verify the location of the PCL on sonogram. Various angles of insonation were applied to examine the echogenicity of the PCL. The result showed that the in situ PCL appeared as a hypoechoic band relative to surrounding tissue on sonogram but it appeared hyperechoic when it was isolated and immersed in a water bath. The specific spatial orientation of the PCL and anisotropy phenomenon contributed to the hypoechogenicity of the PCL in situ on sonogram.
