The efficacy of liposomal bupivacaine compared with traditional peri-articular injection for pain control following total knee arthroplasty: an updated meta-analysis of randomized controlled trials

摘要

BackgroundThe efficacy of postoperative pain management is an important factor that influences the final outcome of total knee arthroplasty (TKA). Whether liposomal bupivacaine offers better efficacy compared with traditional peri-articular injection after TKA remains inconclusive. We conduct this study to compare the true efficacy of liposomal bupivacaine (LB) with traditional peri-articular injection (TPAI) following TKA.
