Extensive Femoral Bone Loss Following Two-Stage Periprosthetic Joint Infection Treatment: Persistent Challenges in Proximal Femoral Replacement.

ABSTRACT:

Background

Proximal femoral replacement (PFR) has gained popularity in nononcological reconstruction surgeries over recent decades. However, there is sparse literature on its application in extensive bone defects following 2-stage revision treatment for periprosthetic joint infection (PJI). This study retrospectively evaluates the clinical and functional outcomes, complication rates, and prosthesis survivorship in patients undergoing PFR surgery for severe bone defects due to 2-stage PJI treatment.

Method

This single-center retrospective study analyzed patients who underwent PFR as part of a 2-stage treatment for hip arthroplasty-related PJI between 2010 and 2020. All patients had extensive proximal femoral bone loss (Paprosky type 3B and 4) before the PFR surgery. Inclusion
