Total Knee Arthroplasty Hospital Costs by Time-Driven Activity-Based Costing: Robotic vs Conventional.

Background: Total knee arthroplasty (TKA) represents a major national health expenditure. The last decade has seen a surge in robotic-assisted TKA (roTKA); however, literature on the costs of roTKA as compared to conventional TKA (cTKA) is limited. The purpose of this study was to assess the costs associated with roTKA as compared to cTKA.

Variation in the Profit Margin for Different Types of Total Joint Arthroplasty.

Background: As health care shifts to a value-based model with bundled-payment methods, it is important to understand the costs and reimbursements of arthroplasty procedures that represent the largest expenditure of Medicare. The aim of the present study was to characterize the variation in (1) total hospital costs, (2) reimbursement, and (3) profit margin for different arthroplasty procedures.

Methods: The total hospital costs of total knee arthroplasty (TKA), total hip arthroplasty (THA), anatomic total shoulder arthroplasty (TSA), reverse shoulder arthroplasty (RSA), and total ankle arthroplasty (TAA) were calculated with use of time-driven activity-based costing at an orthopaedic institution from 2018 to 2020.

The Cost of Hip and Knee Revision Arthroplasty by Diagnosis-Related Groups: Comparing Time-Driven Activity-Based Costing and Traditional Accounting.

Background: Traditional hospital cost accounting (TA) has innate disadvantages that limit the ability to meaningfully measure care pathways and quality improvement. Time-driven activity-based costing (TDABC) allows a meticulous account of costs in primary total joint arthroplasty (TJA). However, differences between TA and TDABC have not been examined in revision hip and knee TJA (rTJA).

Financial Burden of Revision Hip and Knee Arthroplasty at an Orthopedic Specialty Hospital: Higher Costs and Unequal Reimbursements.

Background: As demand for primary total joint arthroplasty (TJA) continues to grow, a proportionate increase in revision TJA (rTJA) is expected. It is essential to understand costs and reimbursement of rTJA as our country moves to bundled payment models. We aimed (1) to characterize implant and total hospital costs, (2) assess reimbursement, and (3) determine revenue for rTJA in comparison with primary TJA.

Reference Pricing Reduces Total Knee Implant Costs.

Background: Reference pricing establishes a set price a hospital is willing to pay for total knee arthroplasty (TKA) components regardless of vendor. The hospital contracts with vendors that sell implants to the hospital at the hospital-dictated prices. Orthopedic surgeons are free to utilize any implant system that has met the reference price using their best clinical judgment.
