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.

Who should consider this trial

Good fit: Ideal candidates are adults over 18 undergoing primary total knee or hip arthroplasty at the University of Miami Hospital.

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.

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 performed: 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.
