Injectable allograft adipose matrices in the management of chronic and postoperative wounds: a retrospective analysis

Wounds. 2022 Oct;34(10):250-253. doi: 10.25270/wnds/21097.

Abstract

Introduction: Clinical options are lacking for the management of chronic wounds or ulcers following failed debridement, skin grafting, or negative pressure wound therapy dressings.

Objective: This retrospective case series evaluated the efficacy of injectable AAM in the management and closure of chronic wounds.

Materials and methods: Patients with nonhealing wounds of any etiology, anatomic location, and length of chronicity were included; those with multiple chronic wounds or prior skin grafting for wound repair were excluded. Data on location, etiology, chronicity, and number of AAM applications were collected for each wound. Patients were evaluated for possible complications related to wound healing and infection. Eleven patients (7 males, 4 females), each with 1 chronic wound, were recruited (average age, 65 years). Wound etiologies were postoperative (n = 7), traumatic (n = 2), and foot ulcer (n = 2). Average wound dimensions were 8.45 mm × 7.36 mm, and the average chronicity was 3.77 months. Ten patients received only 1 application of AAM, and 1 patient received 2 treatments 5 days apart. Average follow-up time was 6.6 weeks.

Results: Seven patients (63%) achieved wound closure, 4 of which (57%) healed within 1 week of application.

Conclusion: Most patients with chronic wounds treated with AAM experienced complete wound closure. AAM shows promising results for enhancing wound healing by providing scaffolding for cell growth.
