Posterolateral and posteromedial corner injuries of the knee

Magn Reson Imaging Clin N Am. 2014 Nov;22(4):581-99. doi: 10.1016/j.mric.2014.08.001. Epub 2014 Nov 1.


Posterolateral (PLC) and posteromedial (PMC) corners of the knee represent complex anatomic regions because of intricate soft tissue and osseous relationships in small areas. Concise knowledge of these relationships is necessary before approaching their evaluation at imaging. Magnetic resonance imaging offers an accurate imaging diagnostic tool to establish normal anatomy and diagnose and characterize soft tissue and osseous injury. It is important to carefully evaluate the PLC and PMC structures on magnetic resonance imaging before planned surgical intervention to avoid potential complications resulting from occult injury.
