Background: Adequate coverage of the knee region is often challenging for plastic and orthopedic surgeons. In the last decade, among several reconstructive techniques, local perforator flaps have become useful reconstructive units. After a wide resection for soft-tissue sarcoma, the knee vascular web may be reasonably damaged and, consequently, perforator flaps based on a local pedicle [such as the distally based anterolateral thigh (ALT) flap] are not reliable. Thus, we harvested a proximally based ALT for knee coverage. Methods: A 52-year-old man underwent local radiation therapy and a wide resection of a soft-tissue sarcoma on the anterior-lateral aspect of the left knee, which resulted in a 15 × 10 cm defect. The defect was covered with a proximally based ALT, through an advancement and propeller relocation of its skin paddle. Results: All margins were tumor free. After 5 days, the donor site was closed primarily because of edema. Neither necrosis of the flap nor dehiscence of the wound was detected. No local relapses were detected at 6-month follow-up. Conclusions: In case of soft-tissue defects of the knee region, with likely involvement of the local vascular web, a local perforator solution is the advancement and propeller proximally based ALT flap.
