(Inter)national Review of Periprosthetic Hip and Knee Fracture Diagnostic and Treatment Strategies

Periprosthetic fractures (PPF) after total hip arthroplasty (THA) and total knee arthroplasty (TKA) complicate care and hinder benchmarking. We asked: which parameters are essential for an international PPF registry? A two-round Delphi consensus with purposive and snowball sampling recruited 30 orthopaedic surgeons (final response rate THA n=25, TKA n=20) from 13 countries. Anonymized, mobile-responsive questionnaires synthesized evidence around Vancouver, Rorabeck, Su and Felix classifications, stability assessment, diagnostics, treatment and outcomes. Consensus (≥75% agree/strongly agree) was reached for all Round-1 and Round-2 items, defining a minimum dataset spanning patient factors, index arthroplasty history, mechanism/timing, bone quality, infection work-up, imaging/classification, implant/stability descriptors, management pathways, and outcomes/complications. This registry-ready specification enables harmonized data capture across institutions and supports quality improvement and comparative effectiveness research. Next steps include multi-site piloting, reliability testing, interoperability mapping, and linkage to patient-reported outcomes.
