A 90-day episode-of-care cost analysis of robotic-arm assisted total knee arthroplasty

Written by Journal of Comparative Effectiveness Research

In this article, the authors assess the efficacy and cost–effectiveness of utilizing a robotic arm in total knee arthroplasty. This research article was originally published in the Journal of Comparative Effectiveness Research.

Knee osteoarthritis (OA) affects approximately 14 million individuals in the USA and although a number of nonsurgical and surgical management modalities exist, total knee arthroplasty (TKA) has been considered the gold standard procedure for end-stage knee OA. Robotic-arm assisted technology has also demonstrated improved bone cut accuracy and precision to plan, component alignment and soft-tissue balancing.

In this study, researchers from Baker Tilly LLP (NY, US), The CORE Institute (AZ, USA) and Lenox Hill Hospital (NY, USA) assessed 519 rTKA and 2595 mTKA procedures for episode-of-care costs, including post-acute services.
