The purpose of this study is to determine how well two different methods of administrating
Tylenol reduce pain and improve patient satisfaction after total hip replacement (THR)
surgery. The methods of administration are orally, via a pill that is to be swallowed, and
intravenously. Our aim is to determine whether oral or intravenous administration of Tylenol
will reduce opioid consumption and opioid-related side effects after THR.
