• Prospective, Randomized Controlled Trial Comparing Continuous Posterior Lumbar Plexus Nerve Block vs Periarticular Injection With Ropivacaine or Liposomal Bupivacaine (Exparel®) on Patients Undergoing Total Hip Arthroplasty Rochester, Minn.

  Total hip arthroplasty is a one of the most commonly performed surgical procedures with increasing numbers anticipated over the next several decades. Differences in the analgesia outcomes between these three intervention groups would provide for an evidenced-based clinical pathway that will emerge as a result of this study.

  Hypothesis:

  Patients undergoing total hip arthroplasty within a clinical pathway utilizing preemptive low-dose opioid and non-opioid medications for multimodal analgesia randomized to peripheral nerve blockade will report less pain with movement on an NRS scale POD #1 compared to randomization to periarticular injection with ropivacaine mixture or periarticular injection with liposomal bupivacaine (Exparel®).
