Post-operative Exparel Study Following Rotator Cuff Repair

The Use of Liposomal Bupivacaine Interscalene Brachial Plexus Block for Rotator Cuff Surgery: A Randomized, Double Blind, Clinical Trial

The primary purpose of this study is to determine if the postoperative oral narcotics consumption in patients receiving liposomal bupivacaine (LB) interscalene brachial plexus nerve block (ISBPB) is different than the narcotics consumption receiving traditional bupivacaine ISBPB for arthroscopic rotator cuff repair analgesia.

Inclusion Criteria:

• Males and females aged 18 years or older with a full-thickness rotator cuff tear (confirmed on MRI) undergoing arthroscopic rotator cuff repair surgery.
• Anesthesiologists physical status 1, 2, or 3 and normal preoperative motor (Lovett scale: biceps, wrist, thumb) and sensory function.

Exclusion Criteria:

• Revision shoulder surgery
• History of more than 1 prior surgery performed on the operative shoulder
• Concomitant severe glenohumeral arthritis
• Concomitant adhesive capsulitis
• Worker's compensation claim
• Pregnancy
• History of hypersensitivity or idiosyncratic reaction to amide-type local anesthetics
• History of renal or hepatic failure
• Chronic neuromuscular deficit affecting the surgical limb.
