VISIE Executes First Pin-Free Knee Bone Cuts Using Spatial Computing

No manual registration, pins, clamps or arrays

AUSTIN, Texas--(BUSINESS WIRE)--VISIE Inc., the spatial computing company delivering the intelligence layer for surgical navigation and robotics, today announced a major technical milestone: the successful execution of all total knee arthroplasty (TKA) bone resections on cadaveric tissue, without the use of pins, clamps, arrays, or manual registration (Warning: Graphic details. See here for a video of the cadaver cuts.)

Unlike traditional navigation for robotic systems, VISIE’s proprietary scanning platform is completely non-invasive. It sees what a surgeon sees without bone-pinned trackers, clamps, or time-consuming registration steps that disrupt a surgeon’s workflow and increase the risk of fractures, infection and post-op pain.

This latest breakthrough marks the first demonstration of complete knee bone cuts powered solely by VISIE’s platform - an upgrade that integrates seamlessly with existing surgical navigation and robotic systems.

“VISIE doesn’t just improve surgical navigation, it rewrites the rules,” said Dr. Brian Blackwood, Orthopedic Surgeon and Clinical Advisor. “This spatial platform delivers the precision that we surgeons need, without pins, clamps, arrays, or compromise. It frees surgical navigation and robotics from the physical hardware we’ve long accepted as necessary and ushers in a new era of anatomic intelligence in the OR.”

Elevating, Not Replacing: A Universal Enabler

This milestone follows VISIE’s award-winning appearance at the 2025 American Academy of Orthopaedic Surgeons (AAOS) meeting, where it took top honors at OrthoPitch for its Continuous Anatomic Auto Tracking (CAAT™) system. CAAT delivers dynamic, real-time anatomical tracking, potentially including cartilage visualization and bone stock assessment—without invasive markers or registration steps.

Challenge Met. Milestone Delivered.

After strong interest and even some skepticism from industry stakeholders, VISIE’s team turned its focus on delivering a proof of concept and successfully achieved this technical milestone in record time.

“Everyone was asking if we could track while cutting bone - so we built it and proved it,” said Douglas Fairbanks, VISIE CEO. “This isn’t just about a saw, it’s about redefining what’s possible when vision replaces hardware like pins, clamps, and arrays.”

Since AAOS, the VISIE team has successfully:

• Designed and built a custom robot with a saw-equipped end-effector
• Executed all five standard femoral cuts—anterior, posterior, anterior chamfer, posterior chamfer, and distal—plus the tibial cut
• Performed all resections on cadaveric tissue tracked entirely through VISIE’s spatial computing system—no pins, clamps, arrays, or registration steps

Roadmap to Clinical Impact

With this milestone complete, VISIE is extending its pinless tracking technology to additional procedures. Early feasibility work is already underway in spine and cranial surgery, supporting VISIE’s vision of delivering the optical intelligence layer for the entire surgical ecosystem.

As surgical systems grow more complex, VISIE simplifies and amplifies—providing universal compatibility, less friction, and more capability.
