Abstract

Background: Diabetic foot ulcers (DFUs) have become a global health concern, which can lead to diabetic foot infection (DFI), lower leg amputation, and even mortality. Though the standard of care (SOC) practices have been recognized as the “gold standard” for DFU care, SOC alone may not be adequate to heal all DFUs and prevent their recurrence. The use of dermal matrix has emerged as an adjuvant treatment to enhance DFU healing. The current study aimed to evaluate the effectiveness and safety of dermal matrix application as an adjuvant treatment to the SOC. Methods: The databases of PubMed, Embase and CENTRAL were independently searched by two authors, with the following key terms: “diabetic foot ulcer”, “acellular dermal matrix”, “wound healing”, and so on. Randomized controlled trials (RCTs) evaluated the efficacy and safety of dermal matrix in the treatment of DFUs were eligible for inclusion. The primary outcomes analyzed included time to complete healing and complete healing rate at the final follow-up, while secondary outcomes included wound area, ulcer recurrence rate, amputation risk and complication risk. Meta-analyses were performed using random-effect or fixed-effect models, based on the heterogeneity test. Results: This study included a total of 15 RCTs with a total of 1524 subjects. Of these, 689 patients were treated with SOC alone, while 835 patients received SOC plus dermal matrix. Compared to the SOC group, significantly shorter time (MD = 2.84, 95%CI: 1.37 ~ 4.32, p < 0.001***) was required to achieve complete healing in dermal matrix group. Significantly higher complete healing rate (OR = 0.40, 95%CI: 0.33 ~ 0.49, p < 0.001***) and lower overall (RR = 1.83, 95%CI: 1.15 ~ 2.93, p = 0.011*) and major (RR = 2.64, 95%CI: 1.30 ~ 5.36, p = 0.007**) amputation risks were achieved in dermal matrix group compared to SOC group. No significant difference was found in the wound area, ulcer recurrence rate, and complication risk between the two groups. Conclusions: The application of dermal matrix as an adjuvant therapy in conjunction with SOC effectively improved the healing process of DFUs and reduced the amputation risk when compared to SOC alone. Furthermore, dermal matrix application was well tolerated by the subjects with no added complication risk.

Overview

CoChat Summary

TL;DR

This systematic review and meta-analysis of 15 RCTs found that adding dermal matrix to standard of care (SOC) improved diabetic foot ulcer healing and reduced amputation risk compared with SOC alone. Dermal matrix did not significantly change wound area, ulcer recurrence, or complication risk.

Key findings

  • Across 15 RCTs and 1524 subjects (689 SOC alone, 835 SOC plus dermal matrix), dermal matrix was associated with significantly shorter time to complete healing (MD = 2.84, 95% CI 1.37–4.32, p < 0.001) and a significantly higher complete healing rate (OR = 0.40, 95% CI 0.33–0.49, p < 0.001).
  • Dermal matrix significantly lowered overall amputation risk (RR = 1.83, 95% CI 1.15–2.93, p = 0.011) and major amputation risk (RR = 2.64, 95% CI 1.30–5.36, p = 0.007), but not minor amputation risk (RR = 1.02, 95% CI 0.49–2.12, p = 0.959).
  • No significant between-group differences were found for wound area (MD = 0.29, 95% CI −0.32–0.91, p = 0.352), ulcer recurrence rate (RR = 1.32, 95% CI 0.92–1.89, p = 0.138), or complication risk (RR = 1.06, 95% CI 0.93–1.20, p = 0.409).
  • Pooled healing rate in the dermal matrix group was 0.70 (95% CI 0.61–0.78), adjusted to 0.56 (95% CI 0.47–0.66) after trim-and-fill for publication bias; pooled ulcer recurrence rate in the dermal matrix group was 0.11 (95% CI 0.05–0.17).

Methods

  • Systematic review and meta-analysis conducted per PRISMA, with PubMed, Embase, and CENTRAL searched independently by two authors using terms including “diabetic foot ulcer,” “acellular dermal matrix,” and “wound healing”; English-language publications were included with no country/date restriction.
  • Eligible studies were prospectively designed RCTs of patients with DFU comparing SOC with dermal matrix, reporting healing rate, healing time, wound area, ulcer recurrence, amputation risk, or complication risk; 15 RCTs were included qualitatively and 14 quantitatively.
  • Meta-analyses used random-effect or fixed-effect models based on heterogeneity (I² ≥ 50% indicated significant heterogeneity); continuous outcomes used mean difference, dichotomous outcomes used odds ratio or risk ratio, and publication bias was assessed with funnel plots, Egger’s and Begg’s tests, and trim-and-fill when indicated.

Limitations

  • The paper states that dermal matrix products varied among manufacturers, treatment blinding was difficult because of the different treatment processes, follow-up times differed across studies, and most available RCTs had relatively small sample sizes and short-term follow-up.
  • The paper also notes high risk of bias for blinding of participants and personnel, and high risk of bias for blinding of outcome assessment in 4 studies.
  • Evident from the text: several pooled analyses had substantial heterogeneity (e.g., I² = 97% for healing time, 86% for healing rate, 98% for wound area, 64% for dermal matrix recurrence rate), and significant publication bias was detected for the pooled dermal matrix healing rate.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

A language model drew the claims from the paper on 2026-11-13, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-11-13 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
