This study aimed to analyze the clinical performance of a PLA-based matrix in the treatment of chronic wounds under real-world conditions in a single-center setting. Methods: This retrospective study included patients with chronic wounds treated with the polylactic acid matrix at Evangelisches Waldkrankenhaus Spandau between February 2023 and February 2025. Wounds were surgically debrided in the operating room prior to matrix application. The matrix remained in place until resorption or detachment, with reapplications occurring at a mean interval of approximately 14 days. Data was anonymized and analyzed descriptively. Results: A total of 14 patients with 16 chronic wounds were treated in this study. The mean patient age was 76.1 years. The most common underlying causes were ischemia and trauma, with an average wound size of 23.6 cm2. Complete wound closure was achieved in 15 out of 16 cases (93.8%), with a mean time to complete wound closure of 72.9 days. The average duration of hospitalization was 24.8 days. Conclusions: The polylactic acid matrix demonstrated a high rate of short-term wound closure in a heterogeneous cohort of chronic wounds, with a mean time to closure of 73 days and no requirement for skin grafting. Further prospective studies with standardized long-term follow-up are warranted.<\/jats:p>","DOI":"10.3390\/jpm16010010","type":"journal-article","created":{"date-parts":[[2025,12,31]],"date-time":"2025-12-31T14:08:11Z","timestamp":1767190091000},"page":"10","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Bioresorbable Polylactic Acid Matrix for Chronic Non-Healing Wounds: First Clinical Experience in Europe"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1627-8002","authenticated-orcid":false,"given":"Ioannis-Fivos","family":"Megas","sequence":"first","affiliation":[{"name":"Department of Orthopaedic and Trauma Surgery, Center of Plastic Surgery, Hand Surgery and Microsurgery, Evangelisches Waldkrankenhaus Spandau, Stadtrandstra\u00dfe 555, 13589 Berlin, Germany"},{"name":"Department of Surgery, Evangelisches Krankenhaus K\u00f6nigin Elisabeth Herzberge, Herzbergstra\u00dfe 79, 10365 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6399-9956","authenticated-orcid":false,"given":"Paul Christian","family":"Fuchs","sequence":"additional","affiliation":[{"name":"Department of Plastic, Reconstructive, Hand and Burn Surgery, Merheim Medical Centre Cologne, University of Witten\/Herdecke, 51109 Cologne, Germany"},{"name":"Department of Health, University of Witten\/Herdecke, 58455 Witten, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Florian","family":"Pinterits","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic and Trauma Surgery, Center of Plastic Surgery, Hand Surgery and Microsurgery, Evangelisches Waldkrankenhaus Spandau, Stadtrandstra\u00dfe 555, 13589 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Akshay Mrigendra","family":"Jain","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic and Trauma Surgery, Center of Plastic Surgery, Hand Surgery and Microsurgery, Evangelisches Waldkrankenhaus Spandau, Stadtrandstra\u00dfe 555, 13589 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Panagiotis","family":"Fikatas","sequence":"additional","affiliation":[{"name":"Department of Surgery, Evangelisches Krankenhaus K\u00f6nigin Elisabeth Herzberge, Herzbergstra\u00dfe 79, 10365 Berlin, Germany"},{"name":"Department of Surgery, Campus Charit\u00e9 Mitte and Campus Virchow-Klinikum, Charit\u00e9-Universit\u00e4tsmedizin, Corporate Member of Freie Universit\u00e4t Berlin, Humboldt-Universit\u00e4t zu Berlin, Berlin Institute of Health, Augustenburger Platz 1, 13353 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G\u00f6tz","family":"Habild","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic and Trauma Surgery, Center of Plastic Surgery, Hand Surgery and Microsurgery, Evangelisches Waldkrankenhaus Spandau, Stadtrandstra\u00dfe 555, 13589 Berlin, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sarina","family":"Delavari","sequence":"additional","affiliation":[{"name":"Department of Plastic, Reconstructive and Hand Surgery, Center for Severe Burn Injuries, Klinikum N\u00fcrnberg, Paracelsus Medical University, Breslauer Str. 201, 90471 Nuremberg, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2966-2863","authenticated-orcid":false,"given":"David","family":"Breidung","sequence":"additional","affiliation":[{"name":"Department of Health, University of Witten\/Herdecke, 58455 Witten, Germany"},{"name":"Department of Plastic Surgery and Hand Surgery, University Hospital Zurich, R\u00e4mistrasse 100, 8091 Zurich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,31]]},"reference":[{"key":"ref_1","first-page":"763","article-title":"Human Skin Wounds: A Major and Snowballing Threat to Public Health and the Economy","volume":"17","author":"Sen","year":"2009","journal-title":"Wound Repair Regen.
