Ligamentous and tendinous structures of the posterolateral corner of the knee provide important static and dynamic stability to the knee joint and act in conjunction with anterior and posterior cruciate ligaments. Injuries of these structures are not uncommon. Failure to treat posterolateral corner injuries leads to posterolateral instability of the knee and subsequently poor outcome of cruciate ligament reconstructions. Currently, MRI is the diagnostic modality of choice in the evaluation of posterolateral corner injuries of the knee. We review normal MR imaging anatomy of the complex anatomical structures of the posterolateral corner of the knee, their biomechanical function, injuries, and current treatment options.
