Introduction and Aim: This study has been undertaken to evaluate efficacy of platelet rich plasma (PRP) dressing that is recently introduced with conventional dressing. We have tried to compare PRP dressing with conventional normal dressing in healing the wound.   Materials and Methods: We conducted this study in 120 patients of chronic non healing diabetic foot ulcers who were treated over the period of three years. Number of cases (60 each) were studied for efficacy of applying autologous platelet rich plasma versus normal dressing for chronic non healing diabetic foot ulcers. At every week follow up, the ulcer was examined for granulation tissue, area and volume which was calculated using Vernier calipers and marked on a graph paper and photographs were taken. Wound healing was compared between PRP and normal dressing.   Results: The incidence of male susceptibility was more (70%) than females (30%) in diabetic foot. Average rate of healing per week was found to be significantly better among the PRP group than normal dressing group. The ulcer showed significant reduction in size among the PRP group in comparison to the normal dressing group with a significant P value (0.001).   Conclusion: In this study application of platelet rich plasma into chronic non-healing diabetic foot ulcers in comparison with conventional dressing has shown a significant reduction in the size of the ulcer, hospital stay and cost for the patient.
