The Efficacy of Liposomal Bupivacaine Using Periarticular Injection in Total Knee Arthroplasty: A Systematic Review and Meta-Analysis.
Total knee arthroplasty (TKA) is gradually emerging as the treatment of choice for end-stage osteoarthritis. In the past, the method of liposomal bupivacaine by periarticular injection (PAI) showed better effects on pain reduction and opioid consumption after surgery. However, some recent studies have reported that liposomal bupivacaine by PAI did not improve pain control and functional recovery in patients undergoing TKA. Therefore, this meta-analysis was conducted to determine whether liposomal bupivacaine provides better pain relief and functional recovery after TKA. ⋯ Compared with the conventional PAI method, liposomal bupivacaine shows similar pain control and functional recovery after TKA. Considering the cost for pain control, liposomal bupivacaine is not worthy of being recommended as a long-acting alternative analgesic agent using the PAI method.
