Background: Diabetic mellitus affects roughly 8.3% of the population in the United States, with more than 79 million people being pre-diabetic. Diabetic foot ulcers are one of the most serious and difficult consequences of diabetes mellitus to manage. Since the dawn of time, several therapy approaches have been tried. The treatment of diabetic foot ulcers has changed dramatically as technology and research have progressed, and the use of collagen dressings in diabetic foot ulcers remains one of them. In diabetic foot ulcers, a comparison of conventional and collagen dressings was made to determine the efficacy.

Methods: A prospective study was undertaken with 50 diabetic foot ulcer patients. Out of the 50 patients, 25 patients were subjected to collagen treatment and 25 patients to conventional treatment with normal saline.

Results: 80% granulation was observed in collagen treated group while there was no granulation was observed in the normal saline-treated group on day 7. The 62% epithelial tissue was present in the collagen treated group whereas 10% epithelial tissue was present in the normal saline-treated group on day 7.

Conclusions: Collagen dressing speeds wound healing in diabetic foot ulcer patients, lowering hospital stay and the necessity for split-thickness skin transplantation. Our research has led us to the conclusion that collagen dressings are superior to conventional dressings.
