The purpose of this research is to evaluate two different standard of care surgeries in treating periprosthetic joint infection (PJI) after total hip and knee arthroplasty. Researchers are looking at differences in outcomes following single versus planned double debridement, antibiotics, and implant retention (DAIR) for acutely infected total hip arthroplasty (THA), and total knee arthroplasties (TKAs).
Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.
An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.
Searching Both is inclusive of interventional and observational studies.
|Eligible Ages||18 Years and Over|
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.
Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.
Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.
Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.
The person who is responsible for the scientific and technical direction of the entire clinical study.

Active Comparator: Single DAIR Surgery Arm
Subjects will undergo a single Debridement Antibiotics and Implant Retention (DAIR) surgical procedure, along with IV antibiotics and followed by oral suppressive antibiotics. This method is currently used and considered to be standard of care.
Active Comparator: Double DAIR Surgery Arm
Subjects will undergo planned double Debridement Antibiotics and Implant Retention (DAIR) surgical procedure, along with IV antibiotics and followed by oral suppressive antibiotics. This method is currently used and considered to be standard of care.
Procedure: - Single Debridement, Antibiotics and Implant Retention
Surgical debridement and wash out of infected joint. The polyethylene (plastic) insert, which acts as the articulating surface (modular component) of the prosthesis, will be removed and the exposed surfaces scrubbed, sterilized, and soaked. A new modular component will be placed with additional irrigation and antiseptic soak. Tissue cultures will be sent to the lab for further evaluation and antibiotic guidance. After the operation subjects will continue six weeks of IV antibiotics followed by oral antibiotic suppression for the life of the implant or at least two years after operation.
Procedure: - Planned Double Debridement, Antibiotics and Implant Retention
Surgical debridement and wash out of infected joint with an additional irrigation and debridement scheduled for approximately 5 days after the initial DAIR. During the first washout, antibiotic cement beads will be placed in the joint and these will remain in the interim until they are removed during the second washout. During the second DAIR, the antibiotic beads are removed, and the modular components are once again removed and replaced with new components. Exposed surfaces are again irrigated and debrided following a standardized protocol. A six-week course of IV antibiotics will follow the DAIR with additional oral antibiotics for the life of the component (standard of care) or at least a minimum of two years.
