About this study
Official title: Dexamethasone in Total Knee Arthroplasty: What Dose Should we be Giving Patients Intraoperatively
The purpose of this study is to determine the most efficacious and safest dexamethasone dose given intraoperatively during total knee arthroplasty that reduces postoperative opioid consumption and pain, improves postoperative nausea and vomiting, and minimizes postoperative complications.
Read the detailed description
Study design: Prospective randomized controlled trial
Scientific Background: In contemporary total joint arthroplasty (TJA), multimodal anesthesia and analgesia is used to improve postoperative pain, reduce opioid consumption, and minimize complications after surgery such as postoperative nausea and vomiting.1-3 Multiple medications with varying mechanisms of action are used at different time points throughout the perioperative period to modulate different pain receptors. Corticosteroids are a medication commonly utilized intraoperatively as part of contemporary multimodal protocols.
Corticosteroids are frequently used in TJA due to their potent anti-inflammatory and anti-emetic properties. Several studies have demonstrated that corticosteroids reduce postoperative nausea and vomiting as well as postoperative pain and opioid consumption.4-6 However, the optimal medication, dose, and number of doses of corticosteroid that should be administered in the perioperative period remain unknown. In addition, it remains unclear if corticosteroids can be safely used in patients with diabetes mellitus or if corticosteroids increase the risk of postoperative complications such as periprosthetic joint infection. Thus, the purpose of our study is to determine the most efficacious and safest dose of corticosteroids that should be administered intraoperatively during TJA.

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Dexamethasone 4mg, Dexamethasone 8 Mg/mL Injectable Suspension and Dexamethasone 16mg in people with Total Knee Arthroplasty, run by Rush University Medical Center at 10 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 10 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 3 Aug 2026). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Opioid Consumption (time frame: 48-hours postoperative (after surgical intervention)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05018091, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Aug 2026.
