Trial summary

It has been shown that a single high dose of steroid before surgery may reduce pain the first 48 hours after insertion of a new joint in the knee, a so called "total knee arthroplasty" (TKA). Consequently, this has been introduced as standard treatment of most patients at several Danish orthopedic departments. Read more about this study

About this study

Official title: Safety Aspects of High-Dose Methylprednisolone in Fast-track Total Knee Arthroplasty

It has been shown that a single high dose of steroid before surgery may reduce pain the first 48 hours after insertion of a new joint in the knee, a so called "total knee arthroplasty" (TKA). Consequently, this has been introduced as standard treatment of most patients at several Danish orthopedic departments. Although there are some concerns about the possibility of increased risk of prosthesis infections, this has not been proved in previous studies. However the studies are few, have limited number of patients and are not done using a standardized perioperative set-up.

This study is made to monitor the safety of a single high dose steroid injection before TKA, with regards to prosthesis infection within one year of surgery.

We hypothesize that there will be no increase in infections in patients receiving steroid injection before TKA compared to a historical cohort of patents who did not receive a steroid injection before their TKA.

Read the detailed description

In order to reduce pain intensity as much as possible after surgical procedures, modern multimodal analgesic strategies using different analgetics targeting different mechanism of the pain reception system are used. At the same time this may reduce the use of opioids, which commonly cause sideeffects such as nausea, vomiting, obstipation,urinary retention, itching, respiratory suppression and sedation.

In spite of the use of a wide perioperative multimodal analgesia, pain after total knee arthroplasty (TKA), is stil a considerable clinical problem and need for optimisation of the immediate postoperative pain treatment. There is evidence that "high"dose glucocorticoids administered preoperatively reduces the level of pain and the use of opioids after surgery. A recent review did not give cause for concern regarding use of glucocorticoids in TKA,but found that data on longterm safety aspects are lacking, why no recommendations could be made.

As the limited evidence presently points to af benefit of glucocorticoids without serious side effects, the treatment has been introduced as standard treatment in TKA at several of the departments participating in the Lundbeck Foundation Centre for fast-track Hip and Knee Replacement collaboration.

This study is made to monitor the safety of high dose steroid injection before TKA, with regards to prosthesis infection within one year of surgery.

We hypothesize that there will be no increase in infections in patients receiving steroid injection before TKA compared to a historical cohort of patents who did not receive a steroid injection before their TKA.

Study groupRoleWhat they receive
High dose SteroidPatients scheduled for primary unilateral elective TKA Age >17 years none of the following contraindications for Methylprednisolone: * Allergy against Methylprednisolone. * Currently in systemic treatment with glucocorticoid * Current gastric ulcer * Insulin dependent diabetes mellitus Citizens without Danish social security number are not eligible for this study as follow-up is not possible.
Historical cohortPatients having primary unilateral elective TKA before initiation of Methylprednisolone as standard treatment age >17 years, Danish social security number and none of the following at time of surgery: * systemic treatment with glucocorticoid defined as: regular prescriptions on glucocorticoid within 2 months prior to surgery. * gastric ulcer defined as: prescriptions on drugs used in "triple therapy" for Helicobacter Pylori infection or prescriptions on antiacids/proton pump inhibitors beginning 1 month before surgery * Insulin dependent diabetes mellitus defined as: any prescriptions on insulin within 6 months prior to surgery
Procedures without SteroidPatients scheduled for primary unilateral elective TKA and age >17 years but who did not receive high dose Methylprednisolone regardless of reason.

What is being measured

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

  1. prosthesis related infections within 1 year after TKA

    Causes if infection are subdivided into the following:

    1. Deep prosthesis related infection
    2. Superficial infection (defined as surgery verified infection above level of the fascia)
    3. Clinical / paraclinical suspicion of infection only treated with intravenous antibiotics (no surgical procedure)
    4. Possible infection, but no clinical/paraclinical suspicion of infection, why the patient is discharged without intravenous antibiotic treatment/surgery.
    5. Surgical wound revision (no clinical/paraclinical suspicion of infection)
    6. Surgical knee manipulation due to limited range of movement (no clinical/paraclinical suspicion of infection).
    7. Surgery due to aseptic non-traumatic loosening of the knee.
    8. Surgery due to traumatic loosening of the knee

    Measured: 1 year

Secondary outcomes (4)
  1. Frequency and cause of hospital stay >4 days

    Patients admitted for >4 days will have their discharge files reviewed with regards to causes of this prolonged" stay. This in accordance with the method used in the Lundbeck Foundation Centre for Fast-track Hip and Knee Replacement registry trials (Clinicaltrials.gov identifier:NCT01515670)

    Measured: primary admission

  2. Frequency and causes of 90 days readmissions

    These will be found through review of medical files and defined as readmission possibly related to surgery and with overnight stay in hospital. These will be classified according to the method used in the ongoing trials in the Lundbeck Foundation Centre for Fast-track Hip and Knee Replacement registry (Clin.trials ID:NCT01515670)

    Measured: 90 days after surgery

  3. Frequencies and causes of readmissions to orthopedic departments 12 months after TKA.

    These will be found through review of medical files and classified appropriately into broad categories depending on data. Detailed information on each case will be recorded

    Measured: 1 year

  4. mortality

    Incidence of 90 days and 1 year mortality will be reported

    Measured: 90 days and 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Infection of Total Knee Joint Prosthesis, run by Copenhagen University Hospital, Rigshospitalet at 7 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 2 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: withdrawn, as of the sponsor's last update on 7 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 7 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.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

prosthesis related infections within 1 year after TKA (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 7 Aug 2024.
