Drs. Ha and Song demonstrate a technique for intraoperatively creating an antibiotic spacer for two-stage treatment of infected TKA. First, an intraoperative mold is made from the removed components and used to create antibiotic spacers with surface contours that are similar to those of the original total knee replacement. The spacers restore leg length and knee stability, which allows limited function during the interval before reimplantation of the new TKA. The technique is cost-effective and convenient and creates a suitably shaped and sized cement spacer for two-stage revision TKA after infection.
