Zimmer Biomet secured U.S. Food and Drug Administration clearance for its enhanced ROSA Knee with OptimiZe system on November 14, 2025, allowing the company to bring a next‑generation robotic‑assisted knee replacement platform to market.
The OptimiZe upgrade adds personalized surgical planning, advanced positioning and tracking, and a streamlined user interface that can cut planning time by an average of 46 percent, giving surgeons faster, more precise workflows and potentially improving patient outcomes.
The new system is designed to work with Zimmer Biomet’s Persona Knee System and integrates with ZBEdge Analytics, enabling data‑driven intra‑operative decision making and performance assessment. The combination of robotics, digital analytics, and a personalized implant platform positions the product to compete directly with Stryker’s Mako system in both inpatient and ambulatory settings.
Zimmer Biomet expects the enhanced ROSA Knee to be commercially available in the United States in the first quarter of 2026, aligning with the growing demand for high‑precision, surgeon‑friendly robotic solutions in orthopedics.
Dr. Peter Sculco, a hip and knee replacement surgeon at the Hospital for Special Surgery, noted that the OptimiZe upgrade “expands on existing benefits of ROSA Knee by giving surgeons new tools to reduce landmark variability, optimize implant placement, and maintain an individualized surgical approach.” The quote underscores the clinical value of the new features and the company’s focus on improving surgical precision.
The FDA clearance reflects Zimmer Biomet’s broader strategy to deepen its robotics portfolio and leverage digital health technologies. By combining the OptimiZe upgrade with the Persona Knee System and ZBEdge Analytics, the company aims to capture a larger share of the rapidly expanding robotic‑surgery market, drive incremental revenue, and reinforce its competitive edge against established rivals.
