These limitations impose a considerable burden, which severely affects patients' quality of life. Autologous platelet\u2010rich fibrin has emerged as a promising regenerative strategy to overcome these challenges; however, its clinical utility is restricted in patients with underlying conditions such as diabetic foot ulcers or impaired platelet function. In this context, allogeneic platelet\u2010rich fibrin has been proposed as a promising therapeutic alternative, offering distinct advantages in selected patient populations. This study provides a comparative evaluation of autologous versus allogeneic platelet\u2010rich fibrin in the management of persistent wounds, specifically assessing wound area reduction, granulation tissue score quality, and time of healing. Seventeen patients with prolonged, chronic non\u2010healing wounds were assigned to two groups: autologous platelet\u2010rich fibrin (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u20096) and allogeneic platelet\u2010rich fibrin (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200911). Despite a significant difference in pre\u2010treatment wound duration (6 vs. 13\u2009weeks,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.05), both groups showed a remarkable reduction in wound area, from a median of 7.50 to 1.25\u2009cm\n                    <jats:sup>2<\/jats:sup>\n                    within 2\u2009weeks, with no statistical difference in healing rates (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&gt;\u20090.05). Granulation tissue scores improved markedly post\u2010treatment, with 64.71% of patients achieving a score of 4\/5, regardless of the source. Autologous platelet\u2010rich fibrin demonstrated a faster complete healing time (30.67 vs. 48.27\u2009days,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.05). Treatment with allogeneic platelet\u2010rich fibrin on a diabetic foot ulcer resulted in an 85.7% reduction in affected area, reaching complete closure within a five\u2010week period. The findings show that while both groups are equally proficient in stimulating wound closure and tissue regeneration, the autologous method may accelerate the final stage of the healing process. This research encourages the broader use of allogeneic alternatives, particularly for patients with insufficient autologous blood, without compromising healing quality.\n
