BACKGROUND: The platelet-rich plasma (PRP) is a product that improves the healing and can help integrate the grafts in chronic wounds. This study aimed to evaluate the results of application of PRP in surgery for skin grafting in chronic wounds. METHOD: We conducted a prospective study, randomized and blinded, in relation to the appraiser, to the use of PRP in skin grafting in chronic wounds. Patients were divided into two groups: group A (control), who received a skin graft, without the use of PRP, and group B, who received a skin graft and the wound was partly used PRP, while the other part served for comparison. RESULTS: There was better graft integration on the side that used the PRP (88.99% in 14th POD and 89.81% at 28 th POD) than the same side of the wound, without PRP (integration was 78.22% in 14th POD and 76.83% at 28th POD). In group A, the integration was even lower (77.85% in 14th POD and 53.45% on the 28th POD). The side that used the PRP has evolved more favorably than group A (p-value = 0.0004) and there was less total loss of the graft in group B than in group A (p-value = 0.049). CONCLUSIONS: The application of PRP in chronic wounds at the time of surgery, improve the integration and evolution of skin grafts and reduces the incidence of total loss.
