Harefuah 2021 May;160(5):301-306

Rambam Health Care Campus, Haifa.

Introduction: Total knee arthroplasty is the most prevalent operation with a high success rate in the treatment of primary osteoarthritis. However, patients with complex secondary osteoarthritis remained marginalized to the surgical response or otherwise exposed to high risk conventional surgery. Early decades of life, surgical history, technical complexity, high surgical morbidity, variability of pathology and anatomy and poor clinical outcome are a few of the reasons. Read More

If we could turn back time: Imagining time-variable, competency-based medical education in the context of COVID-19.

Med Teach 2021 May 23:1-6. Epub 2021 May 23.

Department of Pediatrics, University of Cincinnati College of Medicine, Cincinnati, OH, USA.

The COVID-19 pandemic has exposed a paradox in historical models of medical education: organizations responsible for applying consistent standards for progression have needed to adapt to training environments marked by inconsistency and change. Although some institutions have maintained their traditional requirements, others have accelerated their programs to rush nearly graduated trainees to the front lines. One interpretation of the unplanned shortening of the duration of training programs during a crisis is that standards have been lowered. Read More
