Studies in fat grafting: Part II. Effects of injection mechanics on material properties of fat.

Background: Although fat grafting can address many soft-tissue deficits, results remain inconsistent. In this study, the authors compared physical properties of fat following injection using an automated, low-shear device or the modified Coleman technique.

Methods: Lipoaspirate was obtained from nine patients and processed for injection using either a modified Coleman technique or an automated, low-shear device.
