The objective of this study is to investigate the efficacy of Dexamethasone sodium phosphate plus Methylprednisolone acetate in combination with plain bupivacaine ((B-DEX-MPA) compared with Liposomal Bupivacaine in combination with plain bupivacaine (B-LB) on post-surgical pain control among patients undergoing bilateral total knee arthroplasty (TKA) to asses if perineural B-DEX-MPA will result in superior analgesia efficacy as compared to B-LB.
This study will also assess if perineural B-DEX-MPA results in improved quality of postoperative recovery as compared to B-LB.
This phase 2 clinical trial will investigate the efficacy of Dexamethasone sodium phosphate (DEX) plus Methylprednisolone acetate (MPA) in combination with plain bupivacaine (B) compared with Liposomal Bupivacaine (LB) in combination with plain bupivacaine on post-surgical pain control among patients undergoing bilateral total knee arthroplasty (TKA).
The primary objective of this study is to investigate the efficacy of Dexamethasone sodium phosphate (DEX) plus Methylprednisolone acetate (MPA) in combination with plain bupivacaine (B) compared with Liposomal Bupivacaine (LB) in combination with plain bupivacaine on post-surgical pain control among patients undergoing total knee arthroplasty (TKA). The secondary objective of this study is to test the effects of perineural use of B-DEX-MPA vs B-LB on the quality of postoperative recovery as well as surgical outcome and neuropathic pain among patients undergoing bilateral TKA.
This study will also assess if perineural B-DEX-MPA results in improved quality of postoperative recovery as compared to B-LB.
This will be a single center study at Yale New Haven Hospital (YNHH) performed at two clinical sites: York St. Campus (York Street, New Haven) and St. Raphael Campus (Chapel Street, New Haven). An anticipated 66 participants who are scheduled for primary, elective bilateral TKA will be enrolled.

We will conduct a randomized study based on a randomization table generated by a biostatistician on the day of the surgery by the same investigator who will also prepare the study medication and perform the nerve block procedure. Patients follow up will be performed by investigators blinded to group assignments.

Worst and best postoperative knee pain scores for each surgical knee for days 1, 2 and 7 using Visual analogue scale (VAS) pain score. Score range from 0 (no pain) to 10 (worst pain possible). |
| Day 1, Day 2 and Day 7 |
| Change in functional pain using Brief Pain Inventory (BPI) | Compare functional pain using the BPI at baseline, 6 weeks and 3 months. The BPI scale defines pain as follows: Score: 1 - 4 = Mild Pain, Score: 5 - 6 = Moderate Pain, Score: 7 - 10 = Severe Pain. | baseline, 6 weeks and 3 months |
