Use of Screws and Cement in Revision TKA With Primary or Revision Specific Prosthesis With Up to 17 Years Followup

The purpose of this study was to investigate the use for screws and cement, and primary and revision specific prosthesis for revision TKA. Between July 1989 and February 2010, 839 consecutive revision TKAs were performed, with 609 knees meeting inclusion criteria. At 17 years followup, Kaplan–Meier survivorship was 0.9859 for revision specific prosthesis with screws and cement, 0.9848 for revision prosthesis with no screws, 0.9118 for primary prosthesis with screws, and 0.9424 for primary prosthesis with no screws. Revision TKAs using screws had greater defects (P < .0001). Use of revision prosthesis along with screws and cement to correct largely defective revision TKAs is highly recommended.
