Most shoulders arthroscopies are performed on an outpatient basis. Therefore you will require someone to accompany you to and from surgery. You will not be allowed to leave on your own and must have someone with you the night of surgery. 

Generally speaking, the first 3-5 days following surgery are the most difficult. During this period, it is preferable to have someone who can assist you intermittently through the day with simple daily tasks, such as cleaning, dressing, cooking, and more. During the first 2 weeks, most patients will slowly become more comfortable doing regular day-to-day activities on their own.
