Revision TKA for Instability: Poorer Outcomes after a Previous Aseptic Revision.

Instability is a common indication for early revision total knee arthroplasty (rTKA). The comparative performance of instability rTKA performed after primary TKA and instability rerevision TKA (rrTKA) performed after a previous rTKA performed for any aseptic indication have not been defined. This study was performed to determine the rate of adverse outcomes for patients undergoing aseptic instability TKA revision following a primary TKA or a previous aseptic any-cause rTKA.

Isolated Liner Revision for Total Knee Arthroplasty Instability: A Road That Should Remain Less Taken.

Isolated polyethylene liner exchange (IPLE) is infrequently selected as a treatment approach for patients with primary total knee arthroplasty (TKA) prosthetic joint instability. Potential advantages of less immediate surgical morbidity, faster recovery, and lower procedural cost need to be measured against reoperation and re-revision risk. Few published studies have directly compared IPLE with combined tibial and femoral component revision to treat patients with primary TKA instability.

Revision Total Knee Arthroplasty in Young Patients: Higher Early Reoperation and Rerevision.

Background: Revision total knee arthroplasty (rTKA) rates are increasing in younger patients. Few studies have assessed outcomes of initial aseptic rTKA performed for younger patients compared with traditional-aged patients.

Methods: A detailed medical record review was performed to identify patient demographics, medical comorbidities, surgical rTKA indications, timing from index TKA to rTKA, subsequent reoperation rates, component rerevision rates, and salvage procedures for 147 young patients (158 knees) aged 55 years and younger and for a traditional older cohort of 276 patients (300 knees) between 60 and 75 years.

Do Autopsies Still Matter? The Influence of Autopsy Data on Final Injury Severity Score Calculations.

Background: Despite a proven record of identifying injuries missed during clinical evaluation, the effect of autopsy on injury severity score (ISS) calculation is unknown. We hypothesized that autopsy data would alter final ISS and improve the accuracy of outcome data analyses.

Materials And Methods: All trauma deaths from January 2010 through June 2014 were reviewed.

Establishment of a comprehensive drug overdose fatality surveillance system in Kentucky to inform drug overdose prevention policies, interventions and best practices.

Background: According to the National Center for Health Statistics, Kentucky had the third highest drug overdose fatality rate in the nation in 2015 at 29.9 drug overdose fatalities per 100 000 population.

Objective: The elevated drug overdose fatality rate necessitated the development and implementation of a comprehensive multisource drug overdose fatality surveillance system (DOFSS).

Heroin and fentanyl overdoses in Kentucky: Epidemiology and surveillance.

Background: The study aims to describe recent changes in Kentucky's drug overdose trends related to increased heroin and fentanyl involvement, and to discuss future directions for improved drug overdose surveillance.

Methods: The study used multiple data sources (death certificates, postmortem toxicology results, emergency department [ED] records, law enforcement drug submissions, and prescription drug monitoring records) to describe temporal, geographic, and demographic changes in drug overdoses in Kentucky.

Results: Fentanyl- and heroin-related overdose death rates increased across all age groups from years 2011 to 2015 with the highest rates consistently among 25-34-year-olds.

Infant mortality in coroner/medical examiner investigations.

Infant mortality rate is generally regarded as a fundamental indicator of population health and is often used to validate public health interventions. Hamilton County, Ohio, has one of the highest rates in the nation. Most deaths that do not occur in the hospital fall under the jurisdiction of a coroner/medical examiner.
