What this trial studies

This phase 2, double-blinded, randomized clinical trial aims to evaluate the effectiveness of a combination of Dexamethasone sodium phosphate and Methylprednisolone acetate with plain bupivacaine against Liposomal Bupivacaine with plain bupivacaine for pain control in patients undergoing unilateral total knee arthroplasty. The study will enroll 250 patients at Yale New Haven Hospital, who will be randomly assigned to receive one of the two treatments. Additionally, the trial will assess the quality of postoperative recovery and surgical outcomes associated with each pain management approach.

Who should consider this trial

Good fit: Ideal candidates are patients scheduled for elective, primary, unilateral total knee arthroplasty with ASA status I, II, or III.

Not a fit: Patients with conditions such as coagulopathy, uncontrolled diabetes, or those on opioids may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved pain management and recovery for patients undergoing knee replacement surgery.

How similar studies have performed: Previous studies have shown promise in using corticosteroids for pain management in surgical settings, suggesting potential success for this approach.
