title: Same-Level Fracture of the Tibial Metal Tray and Polyethylene Insert After Total Knee Arthroplasty.
abstract: The authors report a case of failure fracture of the tibial metal tray and polyethylene insert at the same level in a 73-year-old woman 10 years after total knee arthroplasty using the AMK Total Knee System (DePuy, Warsaw, Indiana). Causes of this fracture are analyzed and discussed, with the focus on the importance of component design, position, and size. The overall aim of this case report is for orthopedic surgeons to avoid this complication in total knee arthroplasty by paying attention to these controllable factors.
