About this study

To compare the effects of perioperative intravenous Dexamethasone with a placebo on the severity of persistent postsurgical pain after total knee arthroplasty.

Read the detailed description

It is not clear whether perioperative intravenous Dexamethasone has an effect on severity of persistent postsurgical pain (PPSP) after total knee arthroplasty (TKA). The research hypothesis is that TKA patients experience less severe PPSP after administration of perioperative intravenous Dexamethasone.

Being tested
Dexamethasone, Normal saline solution
Medical subject headings
Osteoarthritis, Knee

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

Study groups in NCT02760459
Study groupRoleWhat they receive
DexamethasoneActive comparatorThe steroid group will receive Dexamethasone 10 mg IV immediately prior to induction of spinal anesthesia and will receive a second and third dose of Dexamethasone 10 mg IV postoperatively at 24 and 48 hrs.
Receives: Drug: Dexamethasone
PlaceboPlacebo comparatorThe control group will receive sterile normal saline solution, serving as placebo, IV immediately prior to induction of spinal anesthesia and will receive a second and third dose of placebo IV postoperatively 24 and 48 hrs. Both Dexamethasone and normal saline solution will be administered as an IV push.
Receives: Drug: Normal saline solution

What is being measured

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

  1. Modified WOMAC scores for pain at 12 weeks postoperative

    using the modified Thai version of the Western Ontario and McMaster (WOMAC) osteoarthritis index for knee osteoarthritis questionnaire

    Measured: 12 weeks

Secondary outcomes (10)
  1. Visual analogue scales for pain during a five-meter walk (0-100)

    Measured: postoperatively at 24, 30, 48, 54, 72 hrs

  2. Visual analogue scales for pain during 45 degree active knee flexion (0-100)

    Measured: postoperatively at 6, 24, 30, 48, 54, 72 hrs

  3. Visual analogue scales for current pain at rest in a supine position (0-100)

    Measured: postoperatively at 6, 24, 30, 48, 54, 72 hrs

  4. Visual analogue scales for maximum pain at rest over the last 24 hours and minimum pain at rest over the last 24 hours (0-100)

    Measured: postoperatively at 0-24, 24-48, 48-72 hrs

  5. Visual analogue scale values for nausea (0-100)

    Measured: postoperatively at 6, 24, 30, 48, 54, 72 hrs

  6. Opioid consumption (mg.)

    Measured: during the first 0-24, 24-48, and 48-72 hrs

  7. Anti-emetic medicine consumption (mg.)

    Measured: during the first 0-24, 24-48, and 48-72 hrs

  8. Maximum degree of active knee flexion

    Measured: postoperatively at 24, 48, 72 hrs, 2 weeks, 6 weeks, and 12 weeks

  9. Modified WOMAC scores for pain

    using the modified Thai version of the Western Ontario and McMaster (WOMAC) osteoarthritis index for knee osteoarthritis questionnaire

    Measured: postoperatively at weeks 2 and 6

  10. Wound complications

    Measured: evaluated postoperatively at weeks 2, 6 and 12

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Dexamethasone and Normal saline solution in people with Osteoarthritis of the Knee, run by Chiang Mai University at 1 site in Thailand.

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 14 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: status not confirmed, as of the sponsor's last update on 10 Oct 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Thailand. 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. Some participants in this study may receive a placebo. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Nitchanant Kitcharanant, MD (+66871071133, nk_win@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Modified WOMAC scores for pain at 12 weeks postoperative (time frame: 12 weeks). 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 NCT02760459, which also lists 2 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 10 Oct 2016.
