About this study

Official title: Effects of Duloxetine on Postoperative Wound Complication of Total Knee Arthroplasty(TKA) in Central Sensitization Patient

Postoperative wound complications such as wound dehiscence, skin necrosis, persistent wound drainage, delayed healing, and superficial skin infection could have devastating consequences, leading to arthroplasty failure and patient morbidity requiring additional operations and prolonging hospitalization with substantial burden in cost of care. Recently, interest and research on central sensitization (CS) have been increasing. CS is closely correlated with excessive pain. It has two main characteristics: allodynia and hyperalgesia. CS is an abnormal and intense enhancement of pain mechanism by the central nervous system. One of the mechanisms by which this excessive pain occurs in CS is reduced activation of descending inhibitory pathway associated with deficiency in pathways primarily in response to serotonin and norepinephrine. Serotonin plays an important role in normal wound healing by affecting the formation of neovascularization, inflammatory reactions, fibroblasts and tissue proliferation essential for wound healing. Norepinephrine is also closely related to wound healing by controlling chemotaxis of macrophage essential for normal wound healing. CS is a risk factor for the development of postoperative wound complication after primary Total Knee Arthroplasty (TKA). Preclinical models of central sensitization suggest that duloxetine is effective in the treatment. Investigators will compare the wound complication following TKA of central sensitization patients in duloxetine group (n=40) with those in non-duloxetine group (n=40). Investigators will classify the central sensitization patients by central sensitization inventory and divide the central sensitization patients in to 2 groups (duloxetine and non-duloxetine group) randomly. Investigators checks the wound complication after primary TKA and visual assessment scale at preoperative, postoperative 2 days and 1, 2,6,12 weeks. All participants will receive postoperative pain control after TKA using the same pain control regimen and wound dressing regimen except duloxetine.

What is being measured

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

  1. The rates of wound complication

    wound dehiscence, suture granuloma, prolonged wound ooze occurring after postoperative day 5, significant hematoma formation, or surgical site infection recorded. Post-operative additional interventions included delayed discharge from hospital due to wound problem, additional outpatient clinic visits to examine the surgical wound, local application of antibiotic ointment, superficial wound debridement or suturing in the office, hematoma aspiration, prescription of antibiotics, or reoperation.

    Measured: Change from baseline wound complication at postoperative 2 days, 1 week, 2 weeks, 6 weeks, 12 weeks

  2. Hormone level

    Cortisol, Serotonin, Norepinephrine related with Central Sensitization and wound healing

    Measured: Change from baseline hormone level at postoperative 2, 6, 12 weeks

Secondary outcomes (2)
  1. Pain Visual Analogue Scale (VAS) score

    Pain evaluation, It will be measured on a scale of 10 points. Minimum point is 0 and maximum point is 10. Higher values represent a worse outcome.

    Measured: Change from baseline VAS score at postoperative 2 days, 1, 2, 6, 12 weeks

  2. Range of motion of the knee joint

    Range of motion

    Measured: Change from baseline range of motion at postoperative 2 days, 1, 2, 6, 12 weeks

Questions about this trial

What is this clinical trial studying?

A study testing Duloxetine in people with Osteoarthritis, Knee, run by The Catholic University of Korea.

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 3 inclusion and 9 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: status not confirmed, as of the sponsor's last update on 19 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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?

Results are not available in the source record.

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?

The rates of wound complication (time frame: Change from baseline wound complication at postoperative 2 days, 1 week, 2 weeks, 6 weeks, 12 weeks). The study lists 2 primary outcomes in all. 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 19 Mar 2019.
