  • offloading orthoses can allow severe wounds to heal by alleviating pressure and restricting movement that can otherwise aggravate and slow healing.
  • vaginal mesh has been used to help further modulate native tissue repair, or decrease re-operative rate, but due to negative secondary effects, mesh kits are banned in some jurisdictions, including the US.
  • Estrogen cream has also been posited as a post-surgical treatment for modulating wound healing, but recent studies from Rahn et al. (Rahn DD, Richter HE, Sung VW, Pruszynski JE, Hynan LS.
