Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are adults over 18 undergoing primary total knee or hip arthroplasty at the University of Miami Hospital.
✕Probably not a fit
Patients with a history of sleep disorders, psychiatric conditions affecting sleep, or those taking sedative medications may not benefit from this study.

What this trial studies
This study investigates the effects of Magnesium-L-Threonate (MgT) on sleep quality and pain reduction in patients who have undergone total knee or hip arthroplasty. Participants will be randomly assigned to receive either MgT or a control treatment. The study aims to determine if MgT can enhance sleep quality post-surgery, which is crucial for recovery and overall well-being. The research is being conducted at the University of Miami Hospital, focusing on patients who are 18 years or older and can provide informed consent.
Why it matters
Potential benefit: If successful, this treatment could significantly improve sleep quality and pain management for patients recovering from joint replacement surgery.
How similar studies have gone: While there is limited data on Magnesium-L-Threonate specifically for sleep post-surgery, similar studies on magnesium supplementation have shown potential benefits in sleep quality.
