Liposomal bupivacaine is a novel method for pain control after total knee arthroplasty (TKA), but recent studies showed no advantage for patients undergoing TKA compared with traditional periarticular injection (PAI). The purpose of this analysis was to compare the clinical outcomes between liposomal bupivacaine treatment and traditional PAI. We retrospectively reviewed data from 16 clinical trials in published databases from their inception to June 2017. The primary outcome was postoperative Visual Analogue Scale (VAS) score and secondary outcomes included opiate usage, narcotic consumption, range of motion, and length of stay. Nine randomized controlled trials and seven nonrandomized controlled trials involving 924 liposomal bupivacaine cases and 1,293 traditional PAI cases were eligible for inclusion in the meta-analysis. No differences were detected in most of the clinical outcomes, except for postoperative VAS within 12 hours and length of stay. This analysis showed that liposomal bupivacaine is not associated with significant improvement in postoperative pain control or other outcomes in TKA compared with PAI.
