Clinical Trial Summary

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.


Clinical Trial 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. ;
