Posterolateral corner injuries represent a complex injury pattern, with damage to important coronal and rotatory stabilizers of the knee. These lesions commonly occur in association with other ligament injuries, making de- cisions regarding treatment challenging. Grade III posterolateral corner injuries result in significant instability and have poor outcomes when treated nonoperatively. As a result, reconstruction is advocated. A thorough knowledge of the anatomy is essential for surgical treatment of this pathology. The following technical note provides a diagnostic approach, postoperative management, and details of a technique for anatomic reconstruction of the 3 main static stabilizers of the posterolateral corner of the knee.
