Investigating Periprosthetic Fracture Cultures in Arthroplasty
Investigating Periprosthetic Fracture Culture Positivity in Patients With Hip and Knee Arthroplasties
University of Chicago
200 participants
Oct 1, 2025
OBSERVATIONAL
Conditions
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.
Eligibility
Inclusion Criteria3
- Adult patients (>18 years old) with periprosthetic fractures around primary or revision hip or knee arthroplasty
- Patients requiring operative management for these fractures (fixation or revision arthroplasty)
- Patients presenting to the University of Chicago Medical Center during two (2) year period (October 2025 to October 2027)
Exclusion Criteria3
- Patients undergoing non-operative management for periprosthetic fractures
- Any documented or reported history of past prosthetic joint infection of the involved joint
- Sinus tract at the time of presentation at the involved joint

Interventions
The investigators are only looking to see the rate of positivity of the cultures as well as what the organisms that are found in the cultures are.
