Failed Same-Calendar-Day Discharges: Understanding the Reasons for an Inpatient Stay Following Intended Outpatient Total Joint Arthroplasty.

Background: The adoption of Same-Calendar-Day discharge, or outpatient, arthroplasty has driven the evolution of care pathway protocols to optimize success rates of discharging patients home on the day of surgery. There are, however, instances where patients are unable to discharge on the same day as intended and require a stay in the hospital. This can lead to a poorer patient and provider care experience as well as incur additional costs.

The patient results and satisfaction of knee arthroplasty in a validated grading system.

Introduction: The validated Knee Osteoarthritis Grading System (KOGS) was implemented and clinical results were compared with patient satisfaction data and implant survivorship in a multi-centre study with surgeons familiar with unicompartmental knee arthroplasty (UKA), patellofemoral arthroplasty (PFA) and total knee arthroplasty (TKA). This is also the first study to evaluate the prevalence of UKA and TKA in consecutive osteoarthritis (OA) knee arthroplasties assessed by this system..

The Knee Osteoarthritis Grading System for Arthroplasty.

Background: The aim of this study is to validate the Knee Osteoarthritis Grading System (KOGS) of progressive osteoarthritic degeneration for the tri-compartmental knee. This system defines the site and severity of osteoarthritis to determine a specific knee arthroplasty.

Methods: The radiographic sequence for KOGS includes standing coronal (anteroposterior), lateral, 30° skyline patella, 15° and 45° Rosenberg and stress views in 20° of flexion.
