The efficacy of local liposomal bupivacaine infiltration on pain and recovery after Total Joint Arthroplasty

BACKGROUND: Total Joint Arthroplasty (TJA) is gradually emerging as the treatment of choice for end-stage osteoarthritis. In the past, Perioperative liposomal bupivacaine treatment is still a controversial subject in TJA. Therefore, we write this systematic review and meta-analysis to evaluate the efficacy of liposomal bupivacaine on pain and recovery after TJA. MATERIALS AND METHODS: Embase, Pubmed, and Cochrane Library were comprehensively searched. Randomized controlled trials (RCTs), cohort studies were included in our meta-analysis. Twelve studies that compared liposomal bupivacaine groups with placebo groups were included in our meta-analysis. The research was reported according to the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines. RCTs were included in our meta-analysis. RESULTS: Our study demonstrated that liposomal bupivacaine group was as effective as the placebo group in term of VAS score at 24 h (P = .09), 48 h (P = .97); Postoperative nausea (P = .72); and LOS (0.27). There was significant difference in terms of total morphine consumption at 24 h (P < .0001), 48 h (P = .0008). CONCLUSION: Our meta-analysis demonstrated that liposomal bupivacaine has similar pain control and functional recovery after TJA which compared with the control group. However, we still need large sample size, high-quality studies to explore the relationship between complications and dose response to give the final conclusion.
