Investigating Periprosthetic Fracture Culture Positivity in Patients With Hip and Knee Arthroplasties
University of Chicago
Summary
This study aims to improve how doctors diagnose infections in patients with broken bones around joint replacements. Currently, there are no clear guidelines to help determine when an infection is present, making treatment decisions difficult. By studying how often infections are found through lab tests and identifying factors that predict infection, the investigators hope to create better ways to diagnose and care for these patients.
Description
All steps in the protocol will be completed under the standard of care for our hospital's orthopedic joints and trauma surgeons. All patients identified under the inclusion criteria will undergo preoperative imaging. In accordance with current standards of care, patients with periprosthetic fractures (PPFs) around the hip will receive three views of X-rays of the hip and femur as well as the anterior-posterior view of the pelvis. Likewise, patients with PPFs around the knee will undergo X-rays that include the knee and femur. No advanced imaging (Computed Tomography, Magnetic Resonance Imaging…
