[Objective]To observe the clinical effect of double-layer artificial dermis in repairing wound with exposed Achilles tendon insertion.[Methods]From April 2015 to August 2020,7 patients received debridement and VSD in the first stage for wound with exposed Achilles tendon insertion,and then had the wound covered with double layer artificial dermis in the second stage as the wounds became fresh and clean.Open the gauze 2～3 days after surgery to observe the wound conditions,and then change the dressing every 3～4 days.Two to three weeks after surgery,pink dermal tissue covered the exposed bone and Achilles tendon,and the wound was naturally epithelialized by regular dressing changes.[Results]All the wounds in the 7 patients completely healed after natural epithelialization in 18～34 days,and no autologous skin grafting was performed in anyone of them.After 6～18 months of follow-up,the repaired wound skin was full and elastic,without obvious scar contracture and pigmentation,and wear-resistant texture without rupture.At the last follow-up,the AOFAS score was(90.6±4.6)and the VSS score was(5.1±1.8).[Conclusion]The application of double-layer artificial dermis is simple,less damaging and ef-fective to repair the wound with exposed Achilles tendon insertion.
