RESUMO
In recent years, the number of diabetic patients has gradually increased, and the number of patients with diabetic foot has also increased. Diabetic foot has a high rate of disability and death, seriously affects the patients' quality of life, shortens life expectancy, and brings heavy social burden. The current treatment methods for diabetic foot are insufficient. The concepts and methods of tissue engineering provide new thoughts and means for the treatment of diabetic foot. This article introduces the pathogenesis of diabetic foot wounds, the factors leading to non-healing of diabetic foot, the applications of functional hydrogel dressings in the treatment of diabetic foot and their technical methods of functional hydrogel dressings for treating skin wounds in diabetic animals, and the future development direction of functional hydrogel dressing for treating diabetic foot wounds is prospected.
