Efficacy and safety of platelet‐rich plasma in the treatment of venous ulcers: A systematic review and meta‐analysis of randomized controlled trials

Abstract

AbstractConsidering the substantial impact of venous ulcers on quality of life and healthcare systems, this study evaluated the efficacy and safety of platelet‐rich plasma (PRP) in comparison to conventional therapy. A systematic review of four databases identified 16 randomized clinical trials, including 20 study groups. PRP significantly enhanced complete ulcer healing, exhibiting an odds ratio (OR) of 5.06 (95% confidence interval [CI]: 2.35–10.89), and increased the percentage of healed ulcer area by a mean difference of 47% (95% CI: 32%–62%). Additionally, PRP shortened the time required for complete healing by an average of 3.25 months (95% CI: −4.06 to −2.43). Although pain reduction was similar in both groups, PRP considerably decreased ulcer recurrence rates (OR = 0.16, 95% CI: 0.05–0.50) without increasing the risks of infection or irritative dermatitis. These results suggest PRP as a viable, safe alternative for venous ulcer treatment, providing significant improvements in healing outcomes.
