Autologous Point-of-Care Adipose Therapy: Delayed Injury/Scar

The goal of this study is to explore if an adipose-based therapeutic strategy can treat contracted scars secondary to soft-tissue burn wounds in injured individuals, especially those with severe burns or soft-tissue loss. The main question it aims to answer are: \- Can autologous layered composite grafting demonstrate non-inferiority compared to full-thickness skin grafting for delayed reconstruction of post-burn or trauma scar contracture? Researchers will compare the single-stage autologous layered composite grafting method to traditional methods to see if it improves healing outcomes, minimizes scarring, and reduces infection risk. Participants will: * Receive fat grafting at time of scar revision. * Undergo simultaneous split-thickness skin grafting for full soft-tissue reconstruction.

Inclusion Criteria: * The proposed study will include adult patients 18 years of age or older, * male or female, * civilian, military, active duty or retired veterans * presenting for scar contracture release and reconstruction at any level. * Additional inclusion criteria includes willingness to be randomized to receive a fat graft. Exclusion Criteria: * Age \< 18 years of age, * active infection, * medical co-morbidities or anatomic configuration deemed by the physician to be a concern for safety, * unwilling or unable to comply with study procedures, * radiation to the site of interest, * prisoners and/or vulnerable populations. * In addition, candidates that are pregnant or plan to become pregnant in the next year, will be excluded.
