About this study

The purpose of this study is the evaluate and improve sleep quality after Total joint replacement.

Read the detailed description

Patients in early stage after TKA tend to suffer from sleep problem. Sleep disturbances frequently occur in patients after surgery, and its occurrence is harmful for postoperative recovery. Many factors can affect the quality of sleep after a major surgery including anesthesia-type, narcotic use and discomfort due to pain or restricted leg movements. Pain directly leads to sleep disruption or even deprivation and, in turn, poor-quality sleep aggravates pain sensation. There seems to be a vicious circle: pain - poor-quality sleep - intensified pain - even poorer-quality sleep.

Presumably, if a patient suffers from catastrophizing, depression and anxiety , the result of TKA will be worse due to poor sleep.

Conditions
Pain After TJA
Being tested
Melatonin 5 mg, Placebo Oral Tablet, Magnesium 500Mg Oral Tablet

What participants receive

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

  • Melatonin 5 mgDrug

    Melatonin is known to induce sleep

  • Placebo Oral TabletDrug

    Placebo

  • Magnesium 500Mg Oral TabletDrug

    Magnesium plays a role in supporting deep, restorative sleep by maintaining healthy levels of GABA, a neurotransmitter that promotes sleep. Research indicates supplemental magnesium can improve sleep quality, especially in people with poor sleep

What is being measured

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

  1. Effect of melatonin and magnesium on pain

    Effect of interventions on pain will be measured. It will done at follow up period of 2 wks, 6 wks and 3 months.

    Measured: 90 days

Secondary outcomes (5)
  1. Effect of melatonin on daily activities

    Effect of interventions daily activities using VAS pain scores. Higher the score. more difficulty in performing daily activities

    Measured: 90 days

  2. Effect of melatonin on daily activities

    Effect of interventions on daily activities using Hip Disability and Osteoarthritis Outcome ( HOOS ) or Knee Disability and Osteoarthritis Outcome ( KOOS) score. The interval score ranges from 0 to 100 where 0 represents total hip/knee disability and 100 represents perfect hip/knee health

    Measured: 90 days

  3. Effect of melatonin on daily activities

    Effect of intervention on daily activities using Western Ontario and McMaster Universities Arthritis Index (WOMAC). Higher scores on the WOMAC indicate worse pain, stiffness, and functional limitations.

    Measured: 90 days

  4. Effect of melatonin on daily activities

    Effect of intervention on daily activities using Pittsberg sleep quality index. Each item is weighted on a 0-3 interval scale. The global PSQI score is then calculated by totaling the seven component scores, providing an overall score ranging from 0 to 21, where lower scores denote a healthier sleep quality.

    Measured: 90 days

  5. Effect of melatonin on daily activities

    Effect of intervention on daily activities using SF 12 score. The lower the score the more disability

    Measured: 90 days

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Melatonin 5 mg and Magnesium 500Mg Oral Tablet in people with Pain After TJA, run by Stanford University at 1 site in United States.

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 0 inclusion and 6 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: withdrawn, as of the sponsor's last update on 11 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

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.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study was withdrawn before enrolling participants, so there are no results.

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?

Effect of melatonin and magnesium on pain (time frame: 90 days). 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 11 Apr 2025.
