The Effect of Peri-Operative Adjunctive Probiotics on Immunological Markers in Cases of Prosthetic Joint Infection of the Hip and Knee
What this study is about
The purpose of this study is to determine whether probiotics in addition to the usual treatment (SOC) can improve immunological markers following treatment for prosthetic joint infection (PJI).
View original scientific description
The purpose of this study is to determine whether probiotics in addition to standard of care (SOC) can improve immunological markers following treatment for prosthetic joint infection (PJI). The study aims to determine whether probiotics in addition to SOC decrease immunological markers following treatment for PJI, improve medical and surgical complications and mortality in patients with PJI, and lead to improved gastrointestinal (GI)-specific patient reported outcomes measures (PROMs) in patients with PJI.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Patients ages 18-90 years of age.
- Diagnosis of PJI based upon Musculoskeletal Infection Society (MSIS) criteria
- Planned treatment with surgical debridement, antibiotics, implant retention (DAIR), single- and two-stage revision total joint arthroplasty (TJA) for PJI with an anticipated plan for eventual discontinuation of oral/IV antibiotics.
- Patients with prior PJI in the same joint that has recurred.
- Patients who understand the benefits and risks associated with taking a probiotic and are willing and able to provide informed consent.
Exclusion criteria
- Fungal PJI.
- Inflammatory bowel disease, diverticulitis, history of intestinal surgery, or gastrointestinal issue where there is concern for gut integrity.
- Severe acute gastrointestinal diseases (active bowel leak, acute colitis, acute pancreatitis).
- Active endocarditis.
- History of pancreatitis
- History of intolerance to probiotics.
- Patients that are pregnant or lactating.
- Immunocompromised patients and patients with immunosuppressive conditions (uncontrolled HIV, chemotherapy for cancer treatment, stem cell transplantation, immunosuppressive medications for solid organ transplant, systematic corticosteroid use, immunosuppressive medications for autoimmune dysfunction, and neonates).
- Patients who are critically ill.
- Revision TJA for aseptic reasons.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
