Plasma or Fibrin Matrix? A Comparative Study between PRP versus PRFM Therapy in Diabetic Foot Ulcer

Abstract

Introduction: Diabetic foot ulcer is one of the most common conditions encountered in surgical OPD. The incidence of a diabetic foot ulcer is around 15% among the diabetic population. Around 80% of non-traumatic amputation is due to chronic diabetic foot ulcer. Recent advances are made in treating wounds in which platelet-rich plasma (PRP) and platelet rich fibrin matrix (PRFM) therapy have proven beneficial. Materials and Methods: A prospective study was conducted from February 2021 to February 2023, for a period of 2 years which included 42 patients. Group A received autologous platelet rich plasma therapy (PRP) and group B received autologous platelet rich fibrin matrix therapy (PRFM) each consisting of 21 patients. Results: PRFM Group showed better reduction in ulcer size compared to respective PRP Group, and demonstrated statistically significant p-values. Around 47% of the subjects had complete closure of the ulcer after 5 sessions of PRP dressing while it was 90% with PRFM dressing.
