Risk Factors And Effect Of Acute Kidney Injury On Outcomes Following Total Hip And Knee Arthroplasty, Zachary S. Aman, Michael Yayac, Alexander J. Rondon, Timothy L. Tan, P. Maxwell Courtney, James J. Purtill

Phase 1

Introduction: Development of acute kidney injury (AKI) following primary total joint arthroplasty (TJA) is a potentially avoidable complication associated with negative outcomes including increased length of stay and mortality. The purpose of this study was to determine the effect of AKI on short-term outcomes and identify risk factors for developing AKI following either total hip or total knee arthroplasty. It was hypothesized that AKI has significant adverse effects on short-term outcomes metrics.

Methods: Patients undergoing primary TJA at a single hospital from 2005 to 2017 were identified and patient demographics, comorbidities, short-term outcomes, and perioperative laboratory results were recorded. …

Dual Mobility Bearing Articulations Result In Lower Rates Of Dislocation After Revision Total Hip Arthroplasty., Zachary Kozick, William Li, Matthew Sherman, Camilo Restrepo, Md, Eric B. Smith, Md, P. Maxwell Courtney, Md

Phase 1

Introduction: The purpose of our study is to directly compare the rates of instability after revision total hip arthroplasty (THA) between a modular dual mobility (DM) and a conventional polyethylene single-bearing surface.

Methods: We retrospectively reviewed a consecutive series of patients who underwent revision THA from 2012 to 2016 at a single institution with a minimum of 2 years of follow-up. Rates of re-revision, dislocation, complications, and short-form (SF-12) scores were compared between the DM and single-bearing groups. To control for confounding variables, a multivariate logistic regression analysis was performed.

Results: Of the 267 revision THA patients, 94 patients …

Selective Serotonin Reuptake Inhibitors Are Associated With Increased Bleeding Related Complications Following Primary Total Hip And Total Knee Arthroplasty, Kyle Plusch, John Stammers, Mbbs, Frcs, Alexus M. Cooper, Chi Xu, Md, Paul Kitei, Md, Javad Parvizi, Md, Frcs, Jess H. Lonner, Md

Phase 1

Introduction: Approximately 10-22% of patients undergoing total hip arthroplasty (THA) and total knee arthroplasty (TKA) are diagnosed with depression. Pre-operative depression is associated with poorer patient reported outcomes, costs and increased complications. Selective serotonin-reuptake inhibitors (SSRIs) are first-line treatment for depression due to their efficacy and low side effect profile. There are conflicting studies regarding SSRI-related bleeding complications. This study compares the rate of bleeding-related complications in THA and TKA patients taking SSRI’s to a control group of non-SSRI users.

Methods: A retrospective single institution study of 16,407 primary THA and TKA’s from 2008 to 2018 was performed. Patients with …
