Osteoarthritis Preface

Abstract

Osteoarthritis (OA) is the leading cause of disability among older adults. It is an incredibly prevalent condition affecting upward of 1 in 8 adults. Societal trends in aging, obesity, and increasing joint injury will lead to a doubling of the number of persons with OA in the next decade. In this context, this issue of Rheumatic Disease Clinics of North America is timely, as we envision this increasingly prevalent disabling condition in an era where health care expenditure is increasingly scrutinized.
