A prospective randomized controlled trial to identify the optimal postoperative pain management in shoulder arthroplasty: liposomal bupivacaine versus continuous interscalene catheter

This prospective randomized controlled trial demonstrated that LB provides excellent postoperative pain relief for shoulder arthroplasty patients. In addition, LB had fewer complications and lower cost, making it a promising addition to a multimodal pain regimen for shoulder arthroplasty.
