Hip and Knee Arthroplasty

Abstract

Variation in care is associated with variation in outcomes after total joint arthroplasty (TJA). Accordingly, much research into enhanced recovery efficacy for TJA has been devoted to linking standardization with better outcomes. This article focuses on recent advances suggesting that variation within a set of core protocol elements may be less important than providing the core elements within enhanced recovery pathways for TJA. Provided the core elements are associated with benefits for patients and health care system outcomes, variation in the details of their provision may contribute to a pathway's success. This article provides an updated review of the literature.
