Zimmer Biomet Receives U.S. FDA Clearance for Enhanced Version of ROSA® Knee Robotic Technology

ROSA^® Knee with OptimiZe^™ Offers Personalized Surgical Planning and Drives Confidence in Delivering Accurate and Reproducible Outcomes¹

WARSAW, Ind., Nov. 14, 2025 /PRNewswire/ -- Zimmer Biomet Holdings, Inc. (NYSE and SIX: ZBH), a global medical technology leader, today announced U.S. Food and Drug Administration (FDA) 510(k) clearance of ROSA^® Knee with OptimiZe^™, an enhanced version of its ROSA^® Knee System that offers a more customized experience for surgeons to help deliver accurate and reproducible outcomes¹ in robotic-assisted total knee replacement surgery.

ROSA Knee with OptimiZe personalizes the surgeon's experience with customized intelligent surgical planning and new positioning, tracking and alignment features to help ensure accuracy¹ and reduce user variability.² The technology provides a simplified user interface that allows surgeons to choose the information they want to see, when they want to see it.

"More and more surgeons are integrating robotic technologies, because they empower surgeons to achieve better outcomes for patients³," said Dr. Peter Sculco, hip and knee replacement surgeon at Hospital for Special Surgery in New York. "ROSA Knee with OptimiZe expands on existing benefits of ROSA Knee by giving surgeons new tools to reduce landmark variability to optimize implant placement and reproducibility.² The enhancement also provides more options to maintain an individualized surgical approach to optimize patient outcomes and surgeon confidence."

Designed for use with the industry leading Persona^® Knee System⁴, ROSA Knee with OptimiZe enables surgeons who use functional alignment to use customizable surgeon profiles that systematically provide surgical plans to automatically position the implant and balance the knee based on the patient's own anatomy and the surgeon's preferences. For surgeons who prefer kinematic alignment, the system offers the industry's only automated kinematic alignment feature to resurface the knee with the goal of restoring its pre-arthritic position and native joint lines.

"As a leader in advancing innovation in orthopedic robotics, we are committed to improving and enhancing our robotic technologies to better meet the needs of surgeons and improve efficiency in the OR, with the ultimate goal of delivering better outcomes for patients," said Shaun Braun, senior vice president and chief information and technology officer at Zimmer Biomet. "ROSA Knee with OptimiZe was designed in partnership with our seasoned team of ROSA surgeons to make robotic-assisted knee replacement surgery more personalized, accurate and efficient for surgeons. With our proprietary algorithm, OptimiZe Planning™, surgeons can create customized profiles that generate personalized surgical plans, which can reduce planning time by an average of 46%."¹

ROSA Knee with OptimiZe features five key enhancements to the ROSA Knee System:

• OptimiZe Planning^™: Creates a customized surgical plan to guide implant positioning based on surgeon individual knee balancing preferences.
• OptimiZe Landmarking^™: Easy-to-use painting feature reduces user landmarking variability.
• OptimiZe Tracking^™: Collaborative resections with motion-sensitive Active Track™ eliminate the need for pinning the Cut Guide to the bone and allows bony resections to remain on plane even with leg movement.
• OptimiZe Kinematic Alignment^™: Automated kinematic alignment plan based on bony landmarks, to resurface the knee to its pre-arthritic position.
• OptimiZe Experience^™: Simplified user interface allows the surgeon to choose specific workflow and display options to tailor user experience for every case.

ROSA Knee with OptimiZe integrates with ZBEdge® Analytics to enable surgeons to make data-driven intra-operative decisions, objectively assess their performance and understand the potential impact of clinical decisions on patient recovery. 

Zimmer Biomet will conduct a targeted release of ROSA Knee with OptimiZe later this year with commercial availability in the U.S. expected in the first quarter of 2026.
