OBJECTIVE: The posterolateral corner of the knee comprises a group of structures that are important to knee stability. MRI is currently the standard imaging technique, but visualization of individual structures is often incomplete. Sonography allows rapid real-time assessment of these superficial structures, but knowledge of the anatomy is essential to allow accurate examination. CONCLUSION: We present an illustrated review of the sonographic anatomy of the posterolateral corner of the knee with MRI correlation.
