PolarisAR is a startup specializing in mixed reality (MR) surgical tech. The company’s flagship product, STELLAR Knee, is designed to assist in knee arthroplasty procedures by providing real-time access to intraoperative anatomic data through MR displays.
STELLAR Knee employs proprietary optical-tracking algorithms and spatial-computing software to measure and capture anatomic data, facilitate intraoperative planning with sub-millimeter precision, and offer resection guidance. In November 2023, the product received 510(k) clearance from the US Food and Drug Administration (FDA). In March 2024, the company announced that surgeons had performed the first total knee arthroplasty (TKA) using its Stellar Knee mixed-reality system.
