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

PFR is effective for limb salvage in complex cases but comes with high mechanical and non-mechanical complications and moderate to poor survival rates. While larger femoral heads and constrained liners help reduce dislocation, infection remains a significant issue. The gap between high MSTS scores and difficulties in daily activities signals a need for improved functional assessment tools. These findings highlight the persistent challenges in managing PJIs.
