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.
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.
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).
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.
