Should megaprosthesis implants be a viable option in elderly patients after distal femur and periprosthetic distal femur fractures?—a retrospective cohort study

Abstract

Background: Distal femur fractures (DFF) and periprosthetic distal femur fractures (PDFF) in elderly patients are challenging to manage, often requiring the use of distal femur replacement (DFR) implants to manage severe bone loss and comminution. The study’s main purpose was to analyze outcomes and complications of DFR implant after DFF or PDFF at our institution to understand the feasibility and reliability of this treatment considering a review of the current literature.
