Background  Chronic non-healing ulcers are a frequent problem in developing countries and represent a heavy burden to the patients because they lack the necessary growth factors (GFs) to maintain the healing process and are frequently complicated by super, added infections. Traditional therapies, such as regular dressings and wound debridement, cannot provide satisfactory results since these treatments are not able to provide the necessary GFs. Platelet-rich plasma (PRP) helps in enhancing the wound healing by releasing various GFs. The aim was to evaluate the efficacy of PRP dressing in the treatment of chronic non-healing ulcers.  Methods  Patients attending the outpatient department on a regular basis and those admitted as inpatients for chronic wound management were included in the study. It was an observational study done in a tertiary health center for a period of one year. All patients with eligible criteria were treated with PRP at twice-weekly intervals for a maximum of 10 dressings. At the end of the five weeks period, the reduction in the size of the ulcers (area and volume) was assessed.  Results  A total of 104 cases with chronic non-healing ulcers of various causes were treated with homologous PRP twice weekly for a maximum of 10 dressings. In those 104 patients, non-healing ulcers in 85 patients (81.73%) were healed at the end of the last dressing. Non-healing ulcers in 13 patients (12.5%) were healed with skin grafting. Among those patients, the baseline mean ulcer area was 5.03 cm 2 . For each visit, there was a reduction in the ulcer area. At the end of the last visit, the mean ulcer area was 1.69 cm 2 , which was significant in this study.  Conclusion  Due to the lack of necessary GFs in chronic non-healing ulcers, PRP is safe and enhances the healing rates of chronic wounds, thereby reducing overall hospital stay and morbidity.
