This is the case of a 21-year-old man who had extensive and bilateral knee soft-tissue damage after a high-voltage electrical discharge. In its reconstruction, we simultaneously performed the pedicled medial sural artery perforator flap. Even though mild complications took place, this alternative proved helpful and reliable, providing an easily adjustable skin island and allowing for the patient's rapid rehabilitation and a satisfactory aesthetic outcome. Although this flap's reconstructive potential is known in other etiologies, the present report outlines its substantial potential in the case of electrical burn injuries, as it has barely been recognized before.
