Visgauss JD, et al. - This study was undertaken to investigate results and survivorship of an unfluted diaphyseal press-fit stem in the setting of mega prosthetic reconstruction. Researchers included a total of 45 individuals (46 stems), with a minimum 3-year follow-up, who underwent reconstruction using 1 of 2 fully porous-coated, unfluted, press-fit stems: Restoration stem with a custom adapter to the Global Modular Restoration System (GMRS), or custom GMRS stem (Stryker). Researchers reviewed 28 femoral (15 Restoration, 13 GMRS) and 14 tibial (6 Restoration, 8 GMRS) stems. All stems were retained without evidence of aseptic loosening, although 7 of 41 (17%) exhibited mild stress shielding at the final follow-up. At midterm follow-up, a non-fluted, press-fit stem applied with a tumor prosthesis provided a stable bone-prosthesis interface.
