Value-based Total Hip and Knee Arthroplasty: A Framework for Understanding the Literature.

Abstract

Since passage of the Patient Protection and Affordable Care Act of 2010, the current decade has witnessed an explosion of the value-based total hip and knee arthroplasty literature. Total hip arthroplasty and total knee arthroplasty are the most common inpatient surgeries for Medicare beneficiaries, and thus, it is no surprise that total joint arthroplasty is currently a prime target of efforts toward cost reduction and quality improvement. The purpose of this review was to provide a framework for understanding the rapidly growing quality and cost literature. Research efforts toward quality improvement are likely to be effective when they address the structure, process, and most importantly outcomes of total joint arthroplasty. Similarly, cost savings should be evaluated with an understanding of existing accounting methods, relationships to the entire cycle of osteoarthritis care, and the direct effect on the quality of care provided.
