Tough Questions in Total Hip and Total Knee Arthroplasty.

Some of today's tough questions surrounding hip and knee arthroplasty involve modifiable risks, bilateral staging, physiotherapy, postoperative activity, venous thromboembolism and infection prophylaxis, pain management, and outpatient settings. The available literature is reviewed to provide answers to difficult questions facing the orthopaedic surgeon. Preoperative questions focus on patient selection, medical optimization, and appropriateness for outpatient surgery.

Mid-Term Clinical Outcomes and Survivorship of a Second-Generation Modular Revision Knee System.

Introduction: Revision knee systems have adapted to the challenges of revision knee arthroplasty with offset stems, augments, cones, and various levels of constraint. The purpose of this study is to review the mid-term outcomes of a second-generation modular knee revision system.

Materials And Methods: A retrospective review was conducted from 2011 through 2014 on all patients who underwent knee arthroplasty with the Vanguard® 360 revision knee system (Zimmer Biomet, Warsaw, Indiana).

Revision of Unicompartmental Knee Arthroplasty to Total Knee Arthroplasty: Is It as Good as a Primary Result?

Background: Unicompartmental knee arthroplasty (UKA) is touted as a more conservative, bone- and tissue-sparing procedure than total knee arthroplasty (TKA). Similarly, revision of UKA to TKA is generally a simpler procedure than revision of TKA to TKA and can be accomplished with primary TKA components in most cases. The purpose of this study was to review a consecutive series of patients undergoing revision of failed UKA to TKA to determine if etiology is similar to that reported in recent literature and evaluate if the results align more with primary TKA vs revision of TKA to TKA.
