Platelet Rich Therapy for Scar Revision

Study Overview
=================
Brief Summary
-----------------
This study will evaluate the efficacy of platelet injections for use of scar therapy post abdominoplasty operations.

Detailed Description
-----------------
Platelet therapy is quickly becoming an integral aspect of both medical and cosmetic procedures. Most notably, Platelet Rich Plasma (PRP) has been used in surgical settings to stimulate healing and promote tissue regeneration. In the field of cosmetic medicine, PRP has been used topically or as an injection to stimulate collagen production and enhance the efficacy of cosmetic procedures such as fat transfer, hair loss therapies, laser treatments, and microneedling. Harvested PRP has platelets, fibrin, and white blood cells, which contribute to wound healing, neocollagenesis, and elastogenesis. Platelet Rich Fibrin (PRF) is the next generation of PRP and contains very high concentrations white blood cells, fibrin and a small amount of mesenchymal stem cells found circulating in our bloodstreams. Due to a lack of anticoagulant in the tube, PRF becomes a gel after 15-20 minutes of being isolated. These properties make PRF useful in reconstructive and aesthetic medicine but may also be beneficial for scar therapy in the same way PRP is currently used.The purpose of this study is to evaluate the efficacy of platelet rich plasma vs. platelet rich fibrin for scar therapy in abdominoplasty who are at least one-year post operation.

Exclusion Criteria: Pregnant and breast-feeding patients are not eligible for this study due to unstudied effects of injectables on the growing fetus and/or breast milk. patients who have undergone other scar therapies for the same scar. chronic health problems that may prevent the investigators from obtaining a viable blood sample, topical infection, any subjects who intend to have other scar procedures during the timeline of the study (12 months including punch biopsy procedures 3 months post treatment and 6 months post treatment).

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Subjects will receive both PRP and PRF injections to the scar. One side will be assigned to PRP and the other PRF (randomly assigned by Clinical Research Coordinator).
Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: PRP<br>Platelet Rich Plasma (PRP) injections into one half of the scar will be preformed. PRP is already considered an effective treatment for scar therapy.This will be randomly assigned by the clinical research coordinator . | Other: Platelet Rich Plasma<br>* Platelet Rich Plasma (PRP) has been used in surgical settings to stimulate healing and promote tissue regeneration. In the field of cosmetic medicine, PRP has been used topically or as an injection to stimulate collagen production and enhance the efficacy of cosmetic procedures such as fat transfer, hair loss therapies, laser treatments, and microneedling. Harvested PRP has platelets, fibrin, and white blood cells, which contribute to wound healing, neocollagenesis, and elastogenesis<br>* Other names: PRP;|
| Experimental: PRF<br>Platelet Rich Fibrin (PRF) injections will be preformed the other half of the scar that is not treated with PRP. PRF has not been established as an effective scar treatment. The PRF will be considered experimental as this study seeks to evaluate if it is more effective than PRP. | Other: Platelet Rich Fibrin<br>* Platelet Rich Fibrin (PRF) is the next generation of PRP and contains very high concentrations white blood cells, fibrin and a small amount of mesenchymal stem cells found circulating in our bloodstreams. Due to a lack of anticoagulant in the tube, PRF becomes a gel after 15-20 minutes of being isolated.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Global Aesthetics Improvement Scale (GAIS) | Blind observer will complete the Global Aesthetics Improvement Scale at 6 months. The scale is from 1-5, where 1 is greatly improved cosmetic outcome and 5 is worsened cosmetic outcome. | 6 months |
