The Posterolateral Corner of the Knee: Anatomic Dissection and Surgical Approach

NULL

J Knee Surg. 2008; 21:50-54 Joshua M. Alpert, ; L. Pearce McCarty, III, ; Bernard R. Bach Jr., ABSTRACT The surgical anatomy and biomechanical role of the posterolateral corner of the knee has received significant attention in recent years. Nevertheless, because of the relative infrequency with which injuries to this area are treated operatively, the surgical approach to this area of the knee may be unfamiliar to many residents and practicing orthopedic surgeons. Accurate knowledge of the appropriate anatomy, planes of dissection, and surgical approach is vital to the safe access of these structures for purposes of repair or reconstruction. This article describes the step-by-step anatomic approach to the posterolateral corner of the knee using paired cadaveric images, with emphasis on the relevant surgical anatomy.
