AAMs include adipose tissue-derived extracellular matrix (ECM) and growth factors (GFs), but not cells. When grafted, AAMs serve as scaffolds with biochemical and biophysical cues for local cell (especially adipocytes) proliferation, regenerating soft tissue, and restoring volume. Being acellular, the AAM is not limited by adipocyte necrosis/apoptosis. <b>Critical Issues:</b> Research on AAM has mostly been conducted on small animal models and with small grafts. Clinically relevant AAM research (large animal models and/or clinical trials) is sparse and limited. To address this gap, we conducted a systematic review of clinically relevant AAM literature to assess AAM's clinical efficacy and safety. Across 11 human and 1 porcine study involving reconstructive or cosmetic procedures, we found that AAMs resulted in significant volume retention, adipogenesis, and angiogenesis, without notable adverse effects. <b>Future Directions:</b> Available quantitative and qualitative data suggest that AAM is an effective and safe alternative to AAG.
