“…The limitations of that previous study, including the lack of standardized technique between surgeons, confounding medications/anesthesia protocols, and a nonrandomized design, have all been addressed in the current study design. The results of this study are to be contrasted with a retrospective, noncontrolled study by Bagsby et al [5], which reported that patients injected with liposomal bupivacaine had higher pain scores at discharge compared with those given traditional PAI (ropivacaine, morphine, and epinephrine). In their study, the finding of higher pain in patients given liposomal bupivacaine was observed in the period between the end of the first 24 hours after surgery and discharge.…”

“…This formulation has been associated with decreased postoperative pain in patients undergoing TJA [6]. However, early comparative studies either had major methodological flaws [5] or were adequately powered but lacked randomization or anesthesia/ injection protocol standardization [6]. We therefore undertook a multicenter, double-blind, three-arm, randomized controlled trial (RCT) to investigate the effectiveness of a liposomal bupivacaine-based PAI (Exparel) versus ropivacaine-based (Naropin; Fresenius Kabi USA, Lake Zurich, IL, USA) PAI with a third arm that included a morphine-based spinal (Duramorph; West-Ward Pharmaceuticals, Eatontown, NJ, USA) in controlling postoperative pain in patients undergoing TJA.…”

“…The clinically related significance of the reduction in pain scores remains unclear; however, they found a reduction in opioid-related adverse events in patients receiving liposomal bupivacaine. Conversely, Bagsby et al [3], in a small retrospective trial comparing liposomal bupivacaine with a traditional periarticular injection for TKA, did not find differences in total narcotic use and furthermore reported worse overall pain scores with liposomal bupivacaine. In the absence of strong findings favoring FNB over liposomal bupivacaine, our data suggest that liposomal bupivacaine poses an advantage over FNB with the ability to provide equivalent pain control, decreased narcotic use, and elimination of an additional procedure, which can cause nerve injury, quadriceps-induced weakness, and in-hospital falls.…”

“…Several retrospective studies reported that liposomal bupivacaine did not improve the quality of postoperative pain profiles, nor did it improve the quality of recovery of these patients [11] or was even worse than a cheaper PAI [2]. This also was true in chronic opioid users scheduled for TKA [16].…”
