Using Retrograde Flow from the Descending Genicular Artery: An Additional Safety Measure in Knee Coverage

Introduction

The knee joint possesses a rich anastomosis of blood vessels comprising of five major arteries.[1] Aside from providing the knee with adequate blood supply, these vessels can be used in free flap surgery for anastomosis or as additional pedicles for added safety. We utilized retrograde flow via the descending genicular artery from the patellar arterial arcade as an additional safety measure for our free latissimus dorsi flap for knee wound coverage.
