Hypertrophic scars are a common global health problem with significant effects on overall quality of life and a huge burden on health care systems especially in Kenya and Africa as a whole due to the high incidence of burns. There are numerous treatment modalities for hypertrophic scarring described in literature. Autologous fat graft have also been suggested.

The 49 adult consenting participants, with hypertrophic scars were recruited. Prior to the administration of the intervention, punch biopsies of their wounds were taken for histology. Pain scores were recorded. AFGs were then injected into the hypertrophic scars at a dose of 1ml/3.5cm2 scar area. Scar assessment by a blinded research assistant was done at day 0 and 28. This assessment was guided by the POSAS scale. A punch biopsy was then collected for histology on day 0 and 28.

There were statistical significant differences between the patients’ scores before and after intervention specifically on pain, itch and characteristics of the scar (color, stiffness, thickness and regularity).
