Acellular Adipose Matrices Seem to Be an Effective and Safe Strategy for Soft Tissue Regeneration and Volume Restoration: A Systematic Review of Clinically Relevant Literature.

Autologous adipose tissue grafting (AAG) can provide soft tissue reconstruction in congenital defects, traumatic injuries, cancer care, or cosmetic procedures; over 94,000 AAG procedures are performed in the United States every year. Despite its effectiveness, the efficiency of AAG is limited by unpredictable adipocyte survival, impacting graft volume retention (26-83%). Acellular adipose matrices (AAMs) have emerged as a potential alternative to AAG.
