Zimmer Biomet has announced a definitive agreement to acquire Monogram Technologies, a developer of hands-free robotic systems for total knee arthroplasty, in a deal valued at $177 million. The acquisition will enhance Zimmer Biomet’s Rosa robotics platform—which already has a new knee implant system under FDA review—while further strengthening its presence in hip and shoulder surgical robotics.
Monogram, based in Austin, Texas, recently received FDA clearance for its semi-autonomous mBôs robotic system for knee replacement surgery, along with its mPress 3D-printed, press-fit implants. The company is also progressing toward a fully autonomous system that enables cutting via a foot pedal, eliminating the need for handheld tools.
Earlier this year, Monogram received approval in India to begin clinical trials using its hands-free robotic saw, with the first live human procedures scheduled for summer 2025.
The AI-powered mBôs robotic arm uses CT imaging to pre-plan bone cuts and set instrument boundaries, helping to protect soft tissue during surgery. Zimmer Biomet and Monogram plan to launch the integrated robotic system using Zimmer Biomet’s own implant line by early 2027.
Zimmer Biomet President and CEO Ivan Tornos called Monogram’s technology “a major leap forward,” highlighting the deal as a bold step toward delivering the most comprehensive and adaptable surgical robotics ecosystem available.
"With Monogram's proprietary technology, Zimmer Biomet is positioned to become the first company to offer fully autonomous orthopedic surgery, setting a new standard of care for the future," Tornos said.
The acquisition includes an upfront cash payment of $4.04 per share, with an additional $12.37 per share tied to future regulatory and commercial milestones through 2030. Including debt and cash adjustments, the enterprise value of the transaction totals $168 million. The deal is expected to close by the end of this year.
Monogram CEO Benjamin Sexson expressed enthusiasm for the partnership:
"Since day one, our mission has been to revolutionize orthopedic robotics for total knee arthroplasty. We are excited to bring our innovations into Zimmer Biomet’s global portfolio and leverage their scale and expertise to drive our shared vision forward."
This acquisition follows Zimmer Biomet’s ongoing expansion in surgical robotics, including recent moves such as acquiring OrthoGrid Systems, further cementing its ambition to lead the next wave of innovation in orthopedic surgery and AI-powered navigation.
