Fix or Replace? Comparable Outcomes with Internal Fixation and Distal Femoral Replacement for Periprosthetic Fractures above Total Knee Arthroplasty

The optimal treatment for periprosthetic fracture (PPfx) around total knee arthroplasty (TKA) remains a topic of debate. Due to its low incidence, comparative studies analyzing arthroplasty and fixation are lacking in the literature. The purpose of this study was to compare the outcomes of distal femoral replacement (DFR) and open reduction and internal fixation (ORIF) for distal femur PPfx.
