Brief Summary

Serotonin-Norepinephrine Reuptake Inhibitor (SNRI) has recently been reported to be effective in controlling pain in persistent chronic pain caused by joint surgery and arthritis. However, opioids are important drugs that still play a pivotal role in pain control after surgery. In this study, we want to investigate the difference of the result among patients who undego total knee arthroplasty (TKA), of the result of pain control after TKA from SNRI administration of duloxetine and opioid in two groups. We designed a randomized controlled study (RCT) for the effect of post-TKA pain control to determine whether SNRI is effective in controlling post-TKA pain compared to Opioid, and whether there is a difference in side effects.

Outcome Measures

Primary Outcomes (2)

  • Pain Visual Analogue Scale

    score ranges 0 to 10, higher score means more painful

    changes of the VAS score from the day before TKA operation and at postoperative 1, 2, 6, 12, 24th weeks and 1 year

  • Brief pain inventory (BPI)

    includes 7 categories. each category score ranges 0 to 10, higher score means more painful

    changes of the BPI score from the day before TKA operation and at postoperative 1, 2, 6, 12, 24th weeks and 1 year

Secondary Outcomes (4)

  • WOMAC(Western Ontario and McMaster University Arthritis Index ) pain scale

    changes of the WOMAC score from the day before TKA operation and at postoperative 1, 2, 6, 12, 24tn weeks and 1 year

  • Intermittent and Constant Osteoarthritis pain (ICOAP) score

    changes of the ICOAP score from the day before TKA operation and at postoperative 1, 2, 6, 12, 24tn weeks and 1 year

  • SF-36(Short Form Health Survey - 36) score

    changes of the SF-36 score from the day before TKA operation and at postoperative 1, 2, 6, 12, 24tn weeks and 1 year

  • Range of Motion

    The day before TKA operation, postoperative 1, 2, 6, 12, 24 weeks and 1 year

Study Arms (2)

Experimental: Duloxetine group

EXPERIMENTAL

Prior to discharge, the drug is prescribed for a total of 6 weeks by dividing the duloxetine-administered group and the opioid-administering group, respectively. The administration period of duloxetine is 6 weeks. The follow-up periods for out-patient clinic are 2 weeks, 6 weeks, 3 months, 6 months, and 1 year after the TKA surgery. During the follow-up period, NSAIDs will be prescribed the same in both groups. As an additional rescue medication, 650 mg of acetaminophen will be allowed to use up to 2g per day.

Drug: Duloxetine vs. Opioid

Active comparator: Opioid group

ACTIVE COMPARATOR

Prior to discharge, the drug is prescribed for a total of 6 weeks by dividing the duloxetine-administered group and the opioid-administering group, respectively. The administration period of opioid is 6 weeks. The follow-up periods for out-patient clinic are 2 weeks, 6 weeks, 3 months, 6 months, and 1 year after the TKA surgery. During the follow-up period, NSAIDs will be prescribed the same in both groups. As an additional rescue medication, 650 mg of acetaminophen will be allowed to use up to 2g per day.

Drug: Duloxetine vs. Opioid

Interventions

Prior to discharge, the drug is prescribed for a total of 6 weeks by dividing the duloxetine-administered group and the opioid-administering group, respectively. The administration period of duloxetine or opioid is 6 weeks. The follow-up periods for out-patient clinic are 2 weeks, 6 weeks, 3 months, 6 months, and 1 year after the TKA surgery. During the follow-up period, NSAIDs will be prescribed the same in both groups. As an additional rescue medication, 650 mg of acetaminophen will be allowed to use up to 2g per day.
