However, the gastrocnemius flap is not always sufficient, and it carries certain donor site morbidity. When local lower limb flaps are insufficient or unavailable, free-tissue transfer is considered. Because few recipient vessels are located around the knee, free-tissue reconstruction remains challenging. In addition, the optimal donor site for large soft-tissue defects has not been clearly established. The anterolateral thigh (ALT) flap is easily accessible and has minor donor site morbidity. We evaluated the reverse-flow ALT pedicled flap as a candidate for the reconstruction of large soft-tissue defects around the knee. We performed a retrospective review of charts between 2005 and 2008. A total of four patients underwent reverse-flow ALT flap for reconstructing large soft-tissue defects around the knee. None of the flaps were augmented in venous drainage with a venous supercharge. We reviewed the defect characteristics, flap size, patient factors, and reconstructive outcomes. The soft-tissue defects were successfully reconstructed for all patients intraoperatively. However, venous congestion of varying degrees developed postopera...
