Reconstruction of below-knee stump using the salvaged foot fillet flap.

Three cases of below-knee stump reconstruction, using cross-legged, free sole flap, free foot filleted flap, and island pedicle sole flap, were reported. The variability of the flap size provided satisfactory coverage as needed in all cases. The causes of amputation were acute trauma and chronic osteomyelitis. The contour of the stump, the sensory recovery, the preserved range of motion of the knee joint, and the long-term durability were satisfactory in these patients. Some pitfalls of this procedure and criteria for evaluating the distal extremity soft tissue with respect to their suitability for use are discussed.
