The Anteromedial Thigh Fasciocutaneous Flap Pedicled on the Supragenicular Septocutaneous Perforator

Skin defects around the knee remain a challenge for the reconstructive surgeons. Choosing appropriate flaps for coverage is crucial to preserve the knee joint or to restore its function. On the basis of anatomic results in 20 cadaveric specimens, we found a constant supragenicular fasciocutaneous perforator within 3 cm above the adductor tubercle, which arose from the saphenous branch of the descending genicular artery. Based on it, the distally pedicled anteromedial thigh fasciocutaneous flap can be harvested from the anteromedial thigh. Between 2003 and 2009, we performed the distally pedicled anteromedial thigh flaps in 11 patients. The site of skin defects included the popliteal fossa, proximal ⅓ leg, and amputation stump below knee. The size of skin defects ranged from 15 × 6 cm to 27 × 9 cm, and the corresponding size of the flaps ranged from 15 × 10 cm to 32 × 9 cm. Of 11 flaps, 10 flaps survived unevently, except 1 flap which suffered partial necrosis due to venous congestion. The patients were followed up for 3 weeks to 12 months. The donor site healed uneventfully without complications in all patients. Additionally, the skin paddle matched with the recipient in terms of skin color, texture, and thickness. The anteromedial thigh fasciocutaneous flap pedicled on the supragenicular perforator is a reliable and versatile alternative to cover skin defects around the knee.
