General information about the trial
|
|||
Main objective of the trial |
To investigate the effect of high dose steroids on the amount of patients with VAS >30 in a 5-meter walktest, 24 hours postoperatively efter total kneearthroplasty in a High Pain responder cohort.
|
||
Protection of trial subjects |
All patients had standardized care, surgery and treatments as part of a Fast-track surgery regimen in Total Knee Arthroplasty surgery, and both study-treatment-groups had active treatment (standard-dose vs. higher dose).
|
||
Background therapy |
Multimodal opioid-sparring analgesia including Cox-2 inhibitors, acetaminophen(paracetamol) and rescue opioids (morphine or oxycodone). All patients had pre- and postoperative tranexamic acid, Local Infiltration Analgesia applied by the surgeon perioperatively, postoperative compression bandage. Perioperative antibiotic regimen of i.v. dicloxacillin 2 g at start of surgery and repeated if body weight >80 kg or if length of surgery >2 h. Dicloxacillin was repeated as 1 g tablet 8 h after end of surgery. Cefuroxim in case of allergy. Thromboprophylaxis was used in-hospital only (xarelto or eliquis). All patients had neuraxial anesthesia with bupivacaine. | ||
Evidence for comparator |
The use of steroids as a perioperative mean of reducing postoperative stress and hence reducing postoperative pain is well-known, and several articles exist on the topic. T.H. Lunn, B.B.

Recruitment
|
||||||||||||||||
Recruitment details |
Patients were recruited before surgery at their information meeting. All participants had had oral and written project information in accordance with guidelines and had at least 24 hours of consideration. All participants gave informed consent. Patients were screened at Hvidovre Hospital and Vejle sygehus from January 2019 to August 2020. | |||||||||||||||
Pre-assignment
|
||||||||||||||||
Screening details |
From February 13, 2019 to August 26, 2020, a total of 1037 patients planned for knee arthroplasty were assessed for inclusion in accordance to inclusion and exclusioncriteria. 25% of screened patients were eligible and 88 patients were included and randomised. | |||||||||||||||

Blinding implementation details |
Randomisation sequence were made by unblinded physicians not otherwise connected to the study or the participants with double-control.
Study-specific trained unblinded nurses at each site, not having any contact with the participants were responsible for preparing the study-drug and blinding this for all other personnel.
Study-drug was mixed into a blinded 100 ml. container, and intervention and control were alike in both volume and appearance.

Adverse events information [1]
|
||||||||||||||||||||||||||||||||||||||||||||||||||||
Timeframe for reporting adverse events |
Serious adverse events were reported on day 0, 1, 2, 7, 30 or 90, or when alerted via our electronic patient record-system, and all SAE were reported within 24h of alert to the Sponsor.
|
|||||||||||||||||||||||||||||||||||||||||||||||||||
Adverse event reporting additional description |
Only Serious adverse events were recorded and reported in accordance with the approval of the Danish medicines agency and local ethics committee, as Dexamethasone is a broadly used and well-approved drug.
If adverse events (not serious adverse events) were reported or suspected of occurring in more than 5% of patients, the sponsor was informed.
