Abstract

This 12-week, prospective, randomised, controlled multi-centre study compared the proportion of healed diabetic foot ulcers and mean healing time between patients receiving acellular matrix (AM) (study group) and standard of care (control group) therapies. Eighty-six patients were randomised into study (47 patients) and control (39 patients) groups. No significant differences in demographics or pre-treatment ulcer data were calculated. Complete healing and mean healing time were 69·6% and 5·7 weeks, respectively, for the study group and 46·2% and 6·8 weeks, respectively, for the control group. The proportion of healed ulcers between the groups was statistically significant (P = 0·0289), with odds of healing in the study group 2·7 times higher than in the control group. Kaplan–Meier survivorship analysis for time to complete healing at 12 weeks showed a significantly higher non healing rate (P = 0·015) for the control group (53·9%) compared with the study group (30·4%). After adjusting for ulcer size at presentation, which was a statistically significant covariate (P = 0·0194), a statistically significant difference in non healing rate between groups was calculated (P = 0·0233), with odds of healing 2·0 times higher in the study versus control group. This study supports the use of single-application AM therapy as an effective treatment of diabetic, neuropathic ulcers.
