About this study

Official title: Pre-emptive Effect of Duloxetine in the Second Knee in Staged Total Knee Arthroplasty: A Randomized Controlled Study

In Korea, the interval between knee arthroplasties is usually 1 week. According to previous studies, when total knee arthroplasty was performed at 1-week intervals, total bleeding was reduced and the period of hospital stay was shortened.

However, if stepwise total knee arthroplasty is performed at intervals of one week, the pain is greater after the second operation, and the reason for this phenomenon is known to be due to central sensitization and opioid resistance.

Therefore, the investigators aim to confirm whether Duloxetine reduces the central sensitization as previously known and affects the pain control after the second operation.

Read the detailed description

Degenerative arthritis of the knee is one of the most common arthritis. Currently, total knee arthroplasty is the most commonly used surgical procedure. The degenerative changes of the knee are often seen on both sides, and bilateral total knee arthroplasty is usually performed. In the past, bilateral total knee arthroplasty was performed at the same time. When bilateral total knee arthroplasty was performed simultaneously, the complications such as increased mortality occurred. So, it is common to perform bilateral total knee arthroplasty in a stepwise manner.

In Korea, the interval between knee arthroplasties is usually 1 week. According to previous studies, when total knee arthroplasty was performed at 1-week intervals, total blood loss was reduced and the period of hospital stay was shortened. However, if stepwise total knee arthroplasty is performed at intervals of one week, the pain is greater after the second operation, and the reason for this phenomenon is known to be due to central sensitization and opioid resistance.

Therefore, the investigators aim to 1) whether the pain is greater than the first operation at the second operation in the control group. 2) whether the pre-operative and post-operative duloxetine use causes the pre-analgesic effect on the second operation. 3) whether the central sensitization, clinical score, and painkiller usage are different by comparing duloxetine-treated group and control group.

What participants receive

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

  • Duloxetine HCl 30mgDrug

    In the duloxetine group, one capsule of Duloxetine HCl 30mg (Duroceptol) is taken orally and daily from the day before the first operation to seven days after the second operation. In the control group, the patients can take painkillers except duloxetine.

Results are not available in the source record.

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

Contact Seung-Baik Kang, MD, PhD (+82-870-3931, ossbkang@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Pain VAS (time frame: day 7 (inpatient)). 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 NCT03792828, which also lists 9 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 3 Jan 2019.
