First Total Knee Replacement Patient Successfully Treated with PolarisAR Revolutionary Mixed-Reality Surgical Guidance System

Monday, March 18, 2024

PolarisAR, a pioneer in advanced mixed-reality surgical guidance technology, has announced the successful completion of the inaugural total knee arthroplasty (TKA) utilizing its innovative STELLAR Knee mixed-reality surgical guidance system. This groundbreaking surgery took place at New York-Presbyterian/Columbia University Irving Medical Center in New York.

The STELLAR Knee system is engineered to revolutionize TKA procedures by providing surgeons with real-time guidance through a mixed-reality surgical navigation platform. It overlays measured and computed data directly onto a 3D environment, empowering surgeons to make informed decisions and streamline operating room workflows.

Operating as a spatial computer, the system ensures continuous data exchange between the surgeon and the software, delivering precision comparable to robotic systems while offering real-time guidance throughout the procedure. Additionally, STELLAR Knee addresses a critical need in hospitals where existing robotic systems may already be in place, offering similar precision in a mixed-reality format and seamlessly integrating into surgical workflows.

STELLAR Knee's design enables precise control over intraoperative variables, surpassing traditional instruments, navigation systems, and early augmented reality platforms. By facilitating meticulous measurement, planning, and guidance, it empowers surgeons to optimize lower limb alignment, soft tissue balance, joint line maintenance, and component positioning.

Traditional TKA techniques have historically encountered challenges such as achieving precise alignment and balance of the lower limb. Closed implant systems and preoperative imaging methods have also limited flexibility and customization, hindering surgeons' ability to tailor procedures to individual patient needs. Additionally, traditional robotic technologies have faced adoption barriers due to their large intraoperative footprint.

In contrast, STELLAR Knee is implant-agnostic and imageless, enhancing accessibility for surgeons. This commitment to democratizing advanced surgical technologies aligns with PolarisAR's goal of expanding access to innovative surgical tools and techniques.
