High-Dose Steroid for Knee Arthroplasty

March 9, 2022 updated by: Niklas Ingemann Nielsen, Copenhagen University Hospital, Hvidovre

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Postoperative pain after 24 hours: VAS
Time Frame: 24 hours

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.
24 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Postoperative opioid usage
Time Frame: 7 days
The amount of rescue opioids given in the postoperative period, and until 7 days after surgery.
7 days
Postoperative antiemetics usage
Time Frame: 7 days
The amount of rescue antiemetics given in the postoperative period, and until 7 days after surgery.
7 days
The inflammatory response expressed by C-reactive protein(CRP).
Time Frame: 2 days
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.
2 days
Postoperative pain summed in the first 7 days
Time Frame: 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.
7 days

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Why still in hospital, an audit into the reasons the patient has not yet been discharged from the ward.
Time Frame: 7 days.

An investigation into reason of why our patients remain in the hospital in the days after total Knee Arthroplasty in our Fast-Track center. This is investigated through a questionnaire previously used in a similar investigation in our center.

The questionnaire is filled in by our project nurse. the questionnaire is a checkmark schedule with predetermined reasons to stay in hospital like low bloodpressure, sedation, dizzyness, lack of physiotherapy and medical and surgical complications.

The outcome assesment will be descriptive.
7 days.
