Monogram Technologies has announced a major milestone in robotic surgery with the successful completion of the world’s first fully autonomous, saw-based robotic knee replacement on a live patient. Conducted on July 26 at Krishna Shalby Hospital in Ahmedabad, India, the procedure was part of a multi-center clinical trial involving 102 patients. This landmark operation is being hailed as a significant step forward in the field of orthopedic robotics.
The procedure used Monogram’s mBôs total knee arthroplasty (TKA) system, which received FDA 510(k) clearance earlier this year. The system employs AI and CT-based planning to guide semi-autonomous and, now, fully autonomous robotic tools in performing knee replacements with enhanced precision and efficiency. The ongoing trial is assessing the system’s safety and effectiveness using implants equivalent to Monogram’s proprietary mPress designs.
Monogram developed the mBôs system with scalability in mind, aiming to eventually extend its capabilities to other orthopedic procedures. The system is expected to enter the market in 2027 under Zimmer Biomet, which is acquiring Monogram. A fully autonomous version is also in the pipeline, reflecting Monogram’s ambition to revolutionize orthopedic care.
CEO Benjamin Sexson described the first live autonomous surgery as a "tremendous milestone" and noted that the system appeared to perform flawlessly during intraoperative evaluations. He expressed confidence that Monogram’s technology will play a transformative role in orthopedic surgery in the coming years.
