Resource utilization and costs for robotic-assisted and manual total knee arthroplasty - a premier healthcare database study.

Introduction: The impact of robotic-assisted total knee arthroplasty (rTKA) vs. traditional, manual TKA (mTKA) on hospital costs is not well documented and is analyzed herein.

Research Design And Methods: Patients in the Premier billing Healthcare Database undergoing elective rTKA or mTKA ("index') in the in- or outpatient setting for knee osteoarthritis between Oct 1, 2015, to September 30th, 2021, were identified.

Does Preoperative Opiate Choice Increase Risk of Postoperative Infection and Subsequent Surgery?

Background: Opioids are commonly prescribed for chronic pain before spinal surgery and research has shown an increased rate of postoperative adverse events in these patients.

Objective: This study compared the incidence of 2-year subsequent surgical procedures and postoperative adverse events in patients undergoing lumbar fusion with or without 90-day preoperative opioid use. We hypothesized that patients using preoperative opioids would have a higher incidence of subsequent surgery and adverse outcomes.
