Reverse flow saphenous island flap in the patient with below-knee amputation.

Three reverse flow island flaps based on the saphenous vessels were successfully transferred. The reverse flow saphenous island flap is harvested on the medial aspect of the lower half of the thigh. This flap is reliable, it can cover the knee and upper half of the leg and is most effective when covering the stump in through-knee or below-knee amputations.
