Measuring Opioid Use After Rotator Cuff Repair: Comparing the Effects of Standard vs. Extended-release Nerve Blocks

The investigators aim to determine if a longer acting nerve block, which is a local anesthetic, can help reduce opioid use after surgery in patients that are getting rotator cuff repair surgery. The investigators will also determine if the longer acting block can reduce the number of days that opioids are taken after surgery. Patients that schedule this type of surgery will be given information regarding the study and asked if they want to participate. If they do, they will be randomized to either receive the standard nerve block or the longer acting nerve block. Participants and physicians will not know which nerve block the participants are receiving. Participants will receive a standard pain medication prescription after surgery and will be asked to record pain scores, medications taken and satisfaction level every day in a journal for two weeks. Participants will be asked to bring in their medication bottles and pain journal to the 2-week follow up appointment. Participants' pain scores will be assessed in the office at the follow up appointment and study staff will conduct a pill count. Participants will return for a 6-week follow up appointment and pain scores will be assessed again at that time, and another pill count will be conducted. At this point the study will be complete.
