Comparison between platelet-rich plasma (PRP) and mechanically emulsified fat grafts in management of chronic wounds.

Background: chronic wounds represent a challenge in treatment, due to diverse pathogenesis, resistance to ordinary treatment complex and lack of direct methods of treatment In this study, the aim is to compare the effect of Platelet -rich plasma (PRP) and mechanically emulsified fat grafts on the outcome of the healing process of chronic wounds.

Patients And Methods: In the current study, 30 patients with chronic wounds were divided into two groups (Group I, 15 patients had application of PRP on chronic wounds). Whereas (Group II, 15 patients had application of mechanically emulsified fat on chronic wounds). In both groups assessment of the healing rates and histopathological changes that were determined by observing the parameters of wound healing, including peri-lesional skin quality, observation of the wound size and depth, assessment of the pain indicated by Visual analog scale score.

Results: Patient were followed up for 6 months. Group II showed a better healing rate 64% in comparison to Group I 55%. Wound parameters and pain score were recorded in both groups with no statistically significant difference.

Conclusion: Both PRP and mechanically emulsified fat grafts were found to be efficient treatment modalities in management of chronic "non-healing" wounds. But mechanically emulsified fat grafts represent a better treatment method for chronic wounds.
