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.
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.

RECRUITINGPostoperative Knee Pain Score
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).
Time frame: Day 1 and Day 2
Postoperative opioid consumption
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
Time frame: From anesthesia end time to discharge time, up to 48 hours
Average Postoperative Knee Pain Score
Average postoperative knee pain scores for postoperative day 7 using Visual analogue scale (VAS) pain score. Score range from 0 (no pain) to 10 (worst pain possible).
Time frame: Day 7
Worst and best pain score
Worst and best postoperative knee pain scores for days 1, 2 and 7 using Visual analogue scale (VAS) pain score. Score range from 0 (no pain) to 10 (worst pain possible).
Time frame: 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.
Time frame: baseline, 6 weeks and 3 months
Change in neuropathic pain using PainDetect
Compare neuropathic pain at baseline, 6 weeks and 3 months using PainDetect: a nine-item questionnaire that consists of seven sensory symptom items for pain that are graded from 0= never to 5= strongly, one temporal item on pain-course pattern graded -1 to +1, and one spatial item on pain radiation graded 0 for no radiation or +2 for radiating pain.
Time frame: baseline, 6 weeks and 3 months
Persistent opioid use using Yale Postoperative Recovery Scale
Persistent opioid use will be compared using the Yale Postoperative Recovery Scale on postoperative day 7, 6 weeks and 3 months. It is comprised of 3 free-text questions: Is patient still taking opioid medications, Yes or No; The number of pills left in pill box;and Has the patient needed a prescription refill, Yes or No.
Time frame: Day 7, 6 weeks and 3 months
Persistent opioid use using NarX
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
Time frame: 6 weeks and 3 months
Change in Quality of Recovery 40 questionnaire
40 questions assessing quality of recovery graded on a five-point Likert scale, total score range from 40 (extremely poor recovery) to 200 (excellent recovery)
Time frame: Day 1, 2 and 7
Prosthetic joint range of motion
Compare prosthetic joint range of motion using the patient's electronic medical record as reported by the physical therapist at baseline, day 0, day 1, and day 2
Time frame: baseline, day 0, day 1 and day 2
Change in Patient-Reported Outcomes Measurement Information System (PROMIS) Global-10
The PROMIS Global-10 is a 10-item patient-reported questionnaire that measures changes in general health in which the response options are presented as 5-point scale, 5 (without any difficulty) to 1 (Unable to do). Higher scores indicate a healthier patient.
Time frame: 6 weeks and 3 months
Change in knee functional status using Knee injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS JR)
Compare knee functional status using KOOS JR at 6 weeks and 3 months after surgery, Scores range from 0 to 100 with a score of 0 indicating total knee disability and 100 indicating perfect knee health.
Time frame: 6 weeks and 3 months
