Prolonged Multimodal Analgesia for Post-Discharge Pain Control After Primary Total Hip Arthroplasty

Prolonged Multimodal Analgesia for Post-Discharge Pain Control After Primary Total Hip Arthroplasty

This is a prospective, three-arm, comparative study with a provider-crossover design. The first arm will comprise the standard of care pain regimen after discharge, which comprises PRN oxycodone, tramadol, and acetaminophen. The second arm will comprise a multimodal pain regimen; however, patients will still be routinely provided PRN oxycodone and tramadol to use on an as needed basis. The third arm will comprise a multimodal pain management protocol, which does not routinely allow for opioid consumption. However, patients will be provided a one week supply of oxycodone and tramadol for emergency pain relief only.
