Liposomal bupivacaine administration is not superior to traditional periarticular injection for postoperative pain management following total knee arthroplasty: a meta-analysis of randomized controlled trials

J Orthop Surg Res. 2023 Mar 16;18(1):206. doi: 10.1186/s13018-023-03699-4.

Abstract

Background: Liposomal bupivacaine (LB) is a relatively new formulation that slowly releases bupivacaine to extend its efficacy for 72-96 h. It is inconclusive whether LB offers better efficacy than traditional periarticular injection (TPAI) following total knee arthroplasty (TKA).

Methods: Relevant randomized controlled trials (RCTs) were searched using electronic databases, including PubMed, Cochrane Library, EMBASE, and Web of Science. Review Manager 5.4.1 was used for calculations.

Results: Sixteen RCTs were included in this meta-analysis. LB had better effects on morphine consumption equivalents during postoperative 24-48 h than TPAI. No significant difference was observed in pain relief, incidence of nausea and vomiting, or length of hospital stay between the two groups.

Conclusion: LB administration during TKA is not superior to TPAI. Studies with larger sample size are needed to validate our findings. PROSPERO registration number: CRD42022355094.

Keywords: Liposomal bupivacaine; Total knee arthroplasty; Traditional periarticular injection.
