BackgroundAnteromedial thigh flaps are far less clinically appealing than their anterolateral counterparts, and are occasionally considered as an alternative to the anterolateral thigh flap. Herein, we report the study of soft-tissue defects reconstruction in the knee using a distally based anteromedial thigh flap pedicled on the rectus femoris branch of the descending branch of the lateral circumflex femoral artery.Patients and methodsBetween July 2008 and September 2016, a distally based anteromedial thigh flap was used to reconstruct soft-tissue defects of the knee in 5 patients (3 males, 2 females; age range at surgery 4–55 years old). The perforating vessels supplying anteromedial thigh were derived from the rectus femoris branch of the lateral circumflex femoral artery. The rectus femoris branch shared a common trunk with the descending branches of the lateral circumflex femoral artery. Defect etiologies included malignant neoplasms in 2 cases and post-burn scar contracture in the remaining 3 cases.ResultsThe average flap size was 19.6 × 9.2 cm (range: 15–24 × 6–12 cm). There was no flap loss. Postoperative muscle weakness occurred in one case. The average follow-up time was 17.8 months (range: 5–36 months). No recurrence of tumor or scar contracture was noted.ConclusionsDistally based anteromedial thigh flaps pedicled on the rectus femoris branch of the descending branch of the lateral circumflex femoral artery may serve as an alternative option to the distally based anterolateral thigh flap for soft-tissue defect reconstruction of the knee.
