The posterolateral corner of the knee.

OBJECTIVE

The purpose of this article is to review the clinical importance and MRI appearances of injuries to the posterolateral corner of the knee.

CONCLUSION

Injuries to the posterolateral corner structures of the knee can cause significant disability due to instability, cartilage degeneration, and cruciate graft failure. Becoming familiar with the anatomy of this region can improve one's ability to detect subtle abnormalities and can perhaps lead to improvements in diagnosing and understanding injuries to this area.
