Abstract
Background: Venous leg ulcers (VLUs) and diabetic foot ulcers (DFUs) are examples of chronic wounds that pose an ongoing health care challenge. Despite significant progress in managing such wounds, challenges persist that require innovative solutions. Cellular, acellular, and matrix-like products (CAMPs) are advanced therapies designed to facilitate chronic wound healing. Polylactic acid (PLA) is a synthetic material used in alloplastic CAMPs that has shown promise in the management of burns and traumatic injuries.
Objective: To retrospectively assess the effect of PLA in promoting chronic wound healing compared with 2 other well-established CAMPs.
Materials and methods: This retrospective chart review, which was conducted in 3 high-volume wound care clinics, aimed to compare the efficacy of 2 advanced wound care products vs a PLA alloplastic CAMP in promoting DFU and VLU closure. The study included 131 wounds treated with a non-CAMP collagen dressing, fish skin grafts (FSGs), or PLA matrices. Inclusion criteria included single Wagner grade 1 or 2 DFUs or Clinical-Etiology-Anatomy-Pathophysiology classification score C6 VLUs, present for at least 12 to 52 weeks, and measuring between 1 cm² and 20 cm². Patients received weekly treatments with 1 of 3 CAMPs, along with standard care. The primary outcome was time to achieve full healing, and the secondary outcome was the proportion of ulcers healed at 12 weeks.
Results: The PLA alloplastic CAMP demonstrated superior outcomes, with a 50% and 20% reduction in time to heal DFUs compared with collagen dressings and FSG, respectively (P < .001). For VLUs, PLA exhibited even more impressive results, achieving 95% and 40% reduction compared with collagen and FSG, respectively (P < .001). PLA allografts displayed a 55% higher rate of full healing by 12 weeks compared with collagen dressings, and a 26% higher rate compared with FSG (P < .001).
Conclusion: This study highlights the unique attributes of PLA for achieving wound closure. PLA-based alloplastic CAMPs are promising treatments, offering rapid healing, increased closure rates, and multifaceted benefits for wound healing.
期刊介绍：
Wounds is the most widely read, peer-reviewed journal focusing on wound care and wound research. The information disseminated to our readers includes valuable research and commentaries on tissue repair and regeneration, biology and biochemistry of wound healing, and clinical management of various wound etiologies.
Our multidisciplinary readership consists of dermatologists, general surgeons, plastic surgeons, vascular surgeons, internal medicine/family practitioners, podiatrists, gerontologists, researchers in industry or academia (PhDs), orthopedic surgeons, infectious disease physicians, nurse practitioners, and physician assistants. These practitioners must be well equipped to deal with a myriad of chronic wound conditions affecting their patients including vascular disease, diabetes, obesity, dermatological disorders, and more.
Whether dealing with a traumatic wound, a surgical or non-skin wound, a burn injury, or a diabetic foot ulcer, wound care professionals turn to Wounds for the latest in research and practice in this ever-growing field of medicine.
