Abstract: Objective  To explore the effect of free anterolateral femoral artery perforator flap on the repair of foot wound and the function of lower extremity.
  Methods  Sixty patients with open foot injury were selected as the research objects, all of them were accompanied with foot fracture.The patients were treated with free anterolateral femoral artery perforator flap. The flap was cut from 4 cm×3 cm-24 cm×12 cm, and the donor area was grafted or sutured.
  Results  In this group, 60 cases of free anterolateral femoral artery perforator flaps survived successfully, with 57 cases of primary wound healing and 3 cases of delayed wound healing. All 60 patients were followed up for 6 to 20 months, with an average of 12 months.There was no hypomyosis in the donor area of the flap, the texture and appearance were satisfactory, the tactile and thermosensory recovery and movement were good, among which 55 flaps were not overstaffed at all, 5 were relatively overstaffed and 5 were severely scarred, and the patient's satisfaction was 95% at the last follow-up. The average healing time was 8.5 months.In the recovery of limb function, 35 cases were excellent, 20 cases were good, 5 cases were medium and 0 cases were poor. The excellent and good rate was 91.67%. 
  Conclusion  The free anterolateral femoral artery perforator flap is thin, and the lateral femoral muscle is not cut. It has little damage to the donor area, and the texture and appearance of the flap are satisfactory. It is helpful for the patients to recover the limb function and meet the requirements of the foot wound repair.
