(A) The MACI scaffold (arrows) is placed on a Tegaderm dressing to provide a stable platform for graft preparation. When the notch is in the lower left corner of the scaffold, the cellular side is facing up. It is imperative to note proper orientation before cutting the graft. (B) The template is placed between the Tegaderm and the scaffold, and the scaffold is cut using tenotomy scissors. It is helpful to have an assistant hold the corners of the graft and Tegaderm stable with small forceps while cutting. (MACI, matrix-induced autologous chondrocyte implantation.)
