Abstract:

Objective　To investigate the efficacy of the descending genicular artery perforator flap for resurfacing limb wounds.　Method　According to the course of the descending genicular artery, branches and anastomosis, the descending artery perforator flap was planned and harvested in a pedicled pattern for reconstruction of defects in the medial aspect of the upper 1/3 of the leg and the knee in 5 cases, and in a free pattern for reconstruction of defects over the hand in 4 cases.　Results　In the total 9 cases of clinical application, all flap survived uneventfully, and the wound healed by first intension. After follow-up of 1 to 24 months, the flaps were excellent in texture, and similar in color to the normal skin, and satisfactory in the appearance, and not impairing the normal function of the limbs.    Conclusion    The descending genicular artery perforator is constant in anatomical location, good in blood supply, and simple in the surgical method, and should be regarded as a feasible approach to reconstruct the limb wounds.
