MRI of the Knee with Arthroscopic Correlation
Major advances in MRI and arthroscopy have allowed for enhanced diagnosis and subsequent management of ligamentous and soft tissue injuries of the knee. Recognition of the appearance of acute ACL and PCL injuries on MRI can enhance arthroscopic reconstruction. PCL injuries are often more subtle and can present with indirect signs. T2-weighted MRI imaging can examine which structures have been damaged in the posterolateral corner which may manifest arthroscopically as a drive-through sign. Characterization of PLC, meniscus, MCL injuries and OCD lesions on MRI have remarkable correlation with arthroscopic findings. This article focuses on current understanding of how MRI and athroscopy can enhance treatment of ligamentous and soft tissue injuries of the knee.
