Yale Steroid Enhanced Versus Exparel Nerveblock TKA RCT Study

Phase 2

Recruiting

• Conditions: Knee Arthroplasty; Total Knee Replacement
• Interventions: Drug: Bupivacaine -Dexamethasone Sodium Phosphate-Methylprednisolone Acetate; Drug: Bupivacaine-Liposomal Bupivacaine

• Registration Number: NCT05279092
• Lead Sponsor: Yale University

Brief Summary

The objective of this phase 2 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 unilateral 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.

Detailed Description

This phase 2, double blinded and randomized 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 unilateral total knee arthroplasty (TKA).

The primary objective of this phase 2 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 unilateral 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). 250 primary, elective and unilateral TKA patients will be enrolled, and equally randomized (1:1 ratio) to receive peripheral nerve blockade with B- LB or B-DEX-MPA.

Arm && Interventions

Group	Intervention	Description
Bupivacaine -Dexamethasone Sodium Phosphate-Methylprednisolone Acetate (B-DEX-MPA)	Bupivacaine -Dexamethasone Sodium Phosphate-Methylprednisolone Acetate	Nerve blockade administration will be carried out per standard of care. All patients will receive single injection under ultrasound guidance with adductor canal block comprised of 30 ml 0.25% plain bupivacaine + 5 mg DEX (0.5 ml) and 40 mg MPA (1 ml); 20 ml 0.25% plain bupivacaine + 5 mg DEX (0.5 ml) and 40 mg MPA (1 ml) will be administered through an iPACK block.
Bupivacaine-Liposomal Bupivacaine (B-LB)	Bupivacaine-Liposomal Bupivacaine	Nerve blockade administration will be carried out per standard of care. All patients will receive single injection under ultrasound guidance with adductor canal block comprised of 20 ml 0.25% plain bupivacaine + 10 ml LB (133 mg) with the total volume of 30 ml; 10 ml 0.25% plain bupivacaine + 10 ml LB (133 mg) with the total volume of 20 ml will be administered through an Interspace between the popliteal artery and capsule of the posterior knee (iPACK) block.

Primary Outcome Measures

Name	Time	Method
Postoperative opioid consumption	From anesthesia end time to discharge time, up to 48 hours	In-hospital postoperative opioid consumption in oral milligram morphine equivalent (OME) will be monitored up to 48-hour between anesthesia end time and discharge time
Postoperative Knee Pain Score	Day 1 and Day 2	Average postoperative knee pain scores for the first two postoperative days using Visual analogue scale (VAS) pain score. Score range from 0 (no pain) to 10 (worst pain possible).

Secondary Outcome Measures

Name	Time	Method
Persistent opioid use using NarX	6 weeks and 3 months	Persistent opioid use will be compared using the NarX score at 6 weeks and 3 months, scores range from 000-999; higher scores indicate more opioid usage

Higher scores indicate a healthier patient.
Persistent opioid use using Yale Postoperative Recovery Scale	Day 7, 6 weeks and 3 months	Persistent opioid use will be compared using the Yale Postoperative Recovery Scale on postoperative day 7, 6 weeks and 3 months.
