Perceptions, Expectations, and Barriers to Robotic-Assisted Total Knee Arthroplasty: A Cross-Sectional Study of 218 Patients.

Objective: To assess the perceptions and expectations of Brazilian patients regarding robotic orthopedic knee surgery, addressing their prior knowledge, technique-related concerns, economic impact, and acceptance of the technology. Methods: The present quantitative, observational, cross-sectional study employed a structured questionnaire administered to 218 orthopedic patients undergoing knee arthroplasty at a specialized outpatient clinic. The study evaluated sociodemographic variables, information sources and levels, expectations regarding benefits, concerns related to robotic surgery, and the economic impact on decision-making. Data analysis used descriptive and inferential statistics (Chi-squared test and logistic regression), with significance set at Results: Most patients (75%) had superficial knowledge about robotic surgery. Their chief sources of information were the attending physicians (40%) and the internet/social media (35%). In total, 60% of the patients had a positive attitude about robotic surgery, with expectations regarding greater precision (70%) and implant durability (55%). However, concerns about high costs (50%) and lack of human control (30%) were common. Willingness to pay for the procedure out of pocket was low (30%), mainly due to its high cost and lack of health insurance coverage. Conclusion: Patients showed high interest in robotic surgery, but they remained hesitant due to economic concerns and the lack of adequate information. Educational strategies and more accessible financing models can significantly increase the acceptance and adoption of this technology in Brazil.
