(a) RPNI constructed with silicone mesh scaffold at postoperative day 111. Note that the myotubes that were implanted within the scaffold have matured and the resultant tissue appears pink and well-vascularized. The silicone mesh remained intact and did not negatively affect viability of the surrounding tissues. (b) RPNI constructed with acellular muscle scaffold at postoperative day 270. (A) implanted electrode; (B) RPNI; (C) peroneal branch of sciatic nerve; and (D) tibial branch of the sciatic nerve.
