A one year follow-up on quality of adherent scars after autologous fat grafting processed by a filtration technique.

Autologous fat grafting (AFG), mostly in combination with adhesiolysis, has become the workhorse for reconstructing a dysfunctional or absent subcutaneous layer. In a previous study we showed that fat grafts isolated by centrifuging led to more than 20 % improvement in scar pliability. Nevertheless, there is still debate on which technique should be used to process and purify fat grafts.

Collagen morphology in human skin and scar tissue: no adaptations in response to mechanical loading at joints.

Dermal collagen displays a random-like structure that has a major role in strength and function of the human integument. It is hypothesised that collagen bundles align in a parallel fashion in the direction of mechanical tension during scarring, which may explain the problematic scar formation that occurs specifically at joints. Scar tissue and normal skin were biopsied from joints and control areas and evaluated by the Fourier analysis.
