Cost Analysis and Bundled Care of Hip and Knee Replacement.

Financial success in a bundled payment system requires knowledge of the costs of care throughout the period of risk. Understanding the significant cost-drivers of total joint arthroplasty (TJA) is crucial in this effort. This article inspects the basics of reimbursement under Medicare's bundled care programs as well as some common investigative tools used in the literature to measure cost. Additionally, the effects of standardized enhanced recovery clinical pathways on costs are reviewed. Finally, drivers of implant costs and several proven measures for implant cost-reduction are evaluated. This review provides surgeons and hospitals successful measures to reduce the cost of TJA via enhanced recovery pathways and reduced implant pricing.
