History of Changes
  Purpose

The primary hypothesis is that those patients who choose an interscalene catheter will have less pain postoperatively than those with single injection blocks. Secondary hypotheses examine physical therapy outcomes and incidence of parasthesia or pain following surgery for up to 3 months.
