Autologous Platelet-Rich Plasma for Diabetic Foot Ulcer.

Application of autologous platelet-rich plasma (PRP), especially leukocyte- and platelet-rich fibrin (L-PRF), has emerged as a promising adjuvant therapy for the treatment of diabetic foot ulcers (DFUs). Conflicting results of PRP efficacy can be attributed to the lack of standardization in the PRP preparation process in addition to a paucity of well-designed randomized clinic trials (RCTs).
