Stellar Knee uses mixed-reality for surgical navigation and guidance. It guides TKA procedures by displaying measured and computed data overlaid directly in a 3D environment. The system acts as a spatial computer, creating continuous data exchange between the surgeon and software. Polaris says this enhances surgical decision-making while simplifying operating room workflow.
