1. An electrosurgical method of treating a chronic wound tissue comprising:

  • positioning an active electrode in proximity to the chronic wound tissue, the chronic wound tissue comprising a wound bed;

    positioning a return electrode in the presence of the chronic wound tissue, the return electrode proximally spaced away from the active electrode;

    delivering an electrically conductive fluid proximate the active electrode;

    applying a high frequency voltage between the active electrode and the return electrode in the presence of the electrically conductive fluid, the high frequency voltage sufficient to generate an ionized vapor layer at the active electrode, wherein the ionized vapor layer debrides at least a portion of the chronic wound tissue and sterilizes at least a portion of the wound bed; and

    applying a skin graft in the vicinity of the wound bed.
