Abstract：Objective To analyze the effect of using a distally based anterolateral thick flap(dALT)to repair lateral knee joint defects.Methods From July 2021 to July 2022,Department of Plastic and Cosmetic Surgery,Zhongnan Hospital of Wuhan University using a retrospective observational study method.We documented and observed the treatment process of 15 patients who underwent full-thickness skin defect repair of the knee joint with a distally based anterolateral thigh flap after previous treatments.We analyzed the effectiveness of this treatment approach.Results All 15 cases showed good blood supply to the flaps post-surgery.In one case,most of the flap survived,but a small portion of the distal edge became necrotic.This was managed with dressing changes,leading to delayed healing.Six months post-discharge,the patient's wound had healed stably,with a satisfactory appearance,and there were no significant restrictions in movement or function of the left lower limb.In another case,the flap largely survived post-treatment,but a small portion around the edge be-came necrotic.Similarly,this was managed with dressing changes,leading to delayed healing.Three months post-surgery,the flap area had healed well,and the skin's protective function was intact.In the remaining 13 patients,only one complication of postoperative hematoma oc-curred within one week after treatment.Healing of hematoma after drainage.Conclusion The transplantation of the distally based antero-lateral thigh flap is an effective surgical method for reconstructing lateral defects of the knee,reducing complications.
