Trial Summary

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. However, if you are on chronic opioids equal to or greater than 90 Morphine Milligram Equivalent (MME) per day, you would not be eligible to participate.

Is light therapy safe for humans?

The research articles provided do not contain specific safety data on light therapy, including Green or White LED light therapy, for postoperative pain or other conditions.12345

How does light therapy differ from other treatments for postoperative pain?

Light therapy is unique because it uses light to reduce pain, which is different from traditional methods like drugs or physical techniques. This approach may offer a non-invasive option with potentially fewer side effects compared to standard pain medications.678910

What is the purpose of this trial?

This is a prospective randomized clinical trial study to investigate two main aspects. The first aspect is to investigate the efficacy exposure to green light emitting diode (GLED) in reducing postoperative opioid medications requirements by 20% as the primary outcome amongst patients scheduled for elective total knee replacement surgery (knee arthroplasty). The second aspect is to reduce postoperative pain by 30%, improve preoperative anxiety by 30%, and improve the quality of sleep pre and postoperatively by 30%.Seventy participants scheduled for elective unilateral primary total knee arthroplasty (total knee replacement) will be recruited from the pain clinic or from the orthopedic surgery clinics at Banner-University Medical Center by the pain or orthopedic physicians who are key personnel of this study. Once a participant is identified, he/she will meet with one of the research team members to explain the nature of the clinical trial and undergo a standard of care medical history gathering and baseline physical examinations. If the participant meets all the inclusion and have no exclusion criteria, he/she will be presented with a written consent in English to explain all the risk and benefits of this clinical trial. Once a participant signs a consent, he or she will be randomized by the study statistician, in a 1:1 ratio to either a GLED group (treatment) or white light-emitting diode (WLED) group (control). The participant will be trained on how to use the light device by one of the research team members. All participants will be exposed to either GLED or WLED for 8 weeks prior to surgery and two additional weeks after surgery.

Treatment Details

Interventions

  • Green LED light therapy
  • White LED light therapy
Trial Overview The study tests if green LED light therapy (GLED) reduces the need for opioid painkillers by 20% after knee surgery. It also aims to cut post-surgery pain by 30%, lessen pre-surgery anxiety by the same amount, and improve sleep quality before and after the operation.
