Abstract

Objective: Recent technological advancements have led to the utilization of robotic-assisted knee arthroplasty (raKA) in the operating room.

Methods: All patients who underwent knee arthroplasty from 2009 to 2013 in NYS SPARCS were reviewed. raKAs and non-raKAs were compared for utilization and institutional trends.

Results: Robotic-assistance increased by 500%. 80% of raKAs were performed in teaching hospitals. The trend increase was greater in teaching hospitals. Blood transfusion rates differed between raKA and non-raKA (6.6% vs. 10.9%, p < 0.001).

Conclusion: raKA utilization increased in NYS, moreso within teaching hospitals. raKA transfusion rates were lower but higher in teaching hospitals, potentially related to learning curve.

Keywords: Robotic surgery; Robotic-assisted surgery; Statewide Planning and Research Cooperative System (SPARCS), New York State (NYS); Total knee arthroplasty; Unicompartmental knee arthroplasty; Utilization trends.
