Abstract
Four patients with soft tissue defects around the ankle joint were covered with peroneal artery perforator-based propeller flaps. Using color Doppler sonography, the flap was designed by considering the location of the perforator and soft tissue defects. The procedure was then performed by rotating the flap by 180o. Additional skin graft was required in a patient due to partial necrosis, and delayed wound repair was performed in another patient with poor blood circulation at the distal part of the flap. The remaining patients did not have any complications and results were considered excellent. Good outcomes were eventually obtained for all patients.

These pictures show coverage of the posterior soft tissue defect with infected Achilles tendon using peroneal artery perforator propeller flap. (A) The perforator was identified and the flap was designed accordingly. (B) The flap was rotated with the perforator as a pivot. (C) The flap was inset and proximal wound was closed primarily. (D) This picture shows postoperative outcome at 7 months follow-up.

These pictures show soft tissue defect and exposure of Achilles tendon after removal of devitalized tissue. (A) This picture shows preoperative state. (B) The flap was designed. (C) The flap was rotated with the perforator as a pivot. (D) The flap was inset and proximal wound was covered by skin graft.
