About this study

Official title: High-Dose Steroid for Total Knee Arthroplasty - A Randomized Doubleblinded Controlled Trial

The purpose of the Study is to test a higher dose of steroids(Dexamethasone) given just prior to surgery in the setting of Fast-Track Kneesurgery with Arthroplasty and the effect on postoperative pain and postoperative inflammation.

Read the detailed description

This study compares a new High-Dose dosage of steroids in the treatment of postoperative pain after Knee Arthroplasty in a Fast-Track setting.

The investigators compare the already used dose(medium dose) with a new high dose(HD) steroid given as an intravenous bolus after the spinal anaesthesia has been given, but before the surgery starts.

The hypothesis is that by attenuating the inflammatory response to the surgery itself by the steroid Dexamethasone, the investigators expect a reduction in postoperative pain upon ambulation 24 hours after unilateral Knee Arthroplasty.

Patients referred to Unilateral Total KneeArthroplasty because of knee-osteoarthritis on Hvidovre Hospital, Capital Region of Denmark or Vejle Hospital, South Region of Denmark are screened and offered inclusion in the study.

The two groups will be randomized and doubleblinded. One group will be treated, as the current guideline in the investigator's Orthopedic fast-track Arthroplasty center, with the medium dose of steroid (0,3 mg dexamethasone/kg bodyweight).

The other group wil be treated with a high dose of steroid (1,0 mg dexamethasone/kg bodyweight).

The patients will be monitored the first 7 days after surgery, during the admission to the hospital, and by a Pain-diary in the patients own home.

Blood tests will be taken preoperatively and postoperatively to determine the effect of the highdose steroid on the inflammatory response. Also a series of blood tests determining the glucose-metabolism after the steroid-admission.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Postoperative pain after 24 hours: VAS

    The amount of patients with moderate postoperative pain in a 5 meter walk test 24 hours postoperatively after total knee-arthroplasty.

    Pain is monitored by the Visual Analog Scale(VAS) 0-100 mm, where 0 is no pain and 100 mm is the worst pain. Moderate pain is considered a VAS >30 mm.

    Measured: 24 hours

Secondary outcomes (4)
  1. Postoperative opioid usage

    The amount of rescue opioids given in the postoperative period, and until 7 days after surgery.

    Measured: 7 days

  2. Postoperative antiemetics usage

    The amount of rescue antiemetics given in the postoperative period, and until 7 days after surgery.

    Measured: 7 days

  3. The inflammatory response expressed by C-reactive protein(CRP).

    The inflammatory response is monitored by the blood-sample c-reactive protein(CRP) and analyzed to se the possible attenuation of the response because of dexamethasone.

    Measured: 2 days

  4. Postoperative pain summed in the first 7 days

    Pain summarized over the first 7 days after surgery, assessed by a summation of the Visual Analog Scale(VAS)-scores in the first 7 days as noted in the pain diary filed in by the participants.

    Measured: 7 days

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Dexamethasone in people with Postoperative Pain and Postoperative Nausea and Vomiting, run by Copenhagen University Hospital, Hvidovre at 2 sites in Denmark.

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 5 inclusion and 7 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 10 Mar 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Denmark. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Postoperative pain after 24 hours: VAS (time frame: 24 hours). 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 NCT03758170, which also lists 1 linked publication.

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 10 Mar 2022.
