Accuracy of imageless versus roentgenographic image-based robotic total knee arthroplasties: a comparative study

Key Points

• The study aims to compare the accuracy of imageless robotic and image-based robotic total knee arthroplasties in component alignment.
• Comparison of two approaches: imageless robotic total knee arthroplasties (RTKAs) versus roentgenographic image-based RTKAs.
• Evaluation focuses on the accuracy of component alignment due to preoperative imaging.
• Clinical implications of alignment accuracy were assessed.
• Preoperative imaging showed a slight improvement in component alignment accuracy in robotic total knee arthroplasties.
• The difference in accuracy, while small, has potential clinical relevance and warrants further study.
