目的　报道应用膝降动脉穿支皮瓣修复肢体创面的临床效果。   方法　根据膝降动脉的走行、分支与吻合的解剖学特点，在膝关节内侧上部设计膝降动脉穿支皮瓣，带血管蒂移位修复小腿上1/3前内侧、膝关节前内侧皮肤软组织缺损5例；游离膝降动脉穿支皮瓣修复手部创面4例。  结果　临床应用共9例，皮瓣均成活，创面一期愈合。经1~24个月随访，皮瓣质地优良、色泽接近正常，外形美观，肢体功能恢复良好。 结论　膝降动脉穿支皮瓣解剖位置恒定、血液供应良好、手术方法简单，是修复肢体创面的可选方法之一。

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.
