In addition to lower extremity orthopedic procedures, liposomal bupivacaine has also been demonstrated to reduce pain after shoulder arthroplasty (joint replacement), a similarly painful shoulder procedure. Liposomal bupivacaine is FDA approved for administration into surgical sites to produce postsurgical analgesia and mitigate pain, but it hasn't been evaluated yet as an intervention to provide analgesia for rotator cuff surgery, though the pain mechanisms for these two procedures, including joint capsule violation and boney intervention are likely similar.
