Management of Periprosthetic Fractures Around a Total Knee Arthroplasty with a Loose Femoral Component
Periprosthetic distal femur fractures (PDFF) are complex problems for the surgeon with the potential for significant complications. The incidence of PDFF has been reported to be between 0.3% and 2.5%. While fixation remains the mainstay in a stable component, revision or use of a distal femoral replacement (DFR) may be required in the setting of a loose component with or without bone loss. The goal of treatment of PDFF is to provide the patient with a stable, painless knee and to minimize malalignment, and in this chapter, we will review the pertinent points to address during the work-up, planning, and execution of operative treatment of PDFF about a loose component.
