In this study, the effect of different wound treatments on contraction was evaluated in an established porcine model. In two separately conducted experiments full thickness wounds treated with artificial dermal substitute, split thickness skin graft (STSG), meshed STSG applied in combination with cultured keratinocytes or meshed STSG alone were compared with untreated wounds. The surface area of all wounds was quantified at regular time intervals. After 20 days wounds from some groups were subjected to histological analysis to establish the degree of epithelialization. Wounds treated with STSG contracted more than with artificial dermal substitute until day 21. From day 21 to day 35 wounds treated with STSG showed the least contraction. Wounds sprayed with cultured keratinocytes demonstrated a slower rate of contraction than those with meshed STSG alone after 20 days. The untreated control wounds showed a greater rate of contraction and had almost closed by day 20. This study demonstrates that there is a significant difference in contraction between wounds treated with artificial dermal substitute and control wounds and between wounds treated with STSG with cultured keratinocytes and meshed STSG alone. STSG with cultured keratinocytes, unmeshed STSG, and artificial dermal substitute all reduced wound contraction significantly.
