Intelligent orthopedic implants. Continuous visibility into recovery.
These Three Medical develops intelligent sensor-enabled implants that give orthopedic surgeons continuous visibility into post-operative recovery and long-term implant performance.
Discover how our cutting-edge technology is reshaping the future of orthopedic care, offering precision and enhanced patient outcomes.
Continuous post-operative monitoring during the critical recovery window,
Early signal of complications before they become clinical events.
Surgeon-centric workflow integration — data feeds existing clinical surfaces.
Multi-modal sensing across temperature, motion, and biomechanical signals.
The Opportunity
Over 800,000 total knee arthroplasties are performed annually in the United States, and that number is growing with demographic trends. Most patients recover well. The patients who don’t — those who develop infection, instability, slow healing, or eventual revision — represent the highest-cost and highest-stakes outcomes in the field.
Today, surgeons see their patients at scheduled follow-ups or when something goes wrong. The months between visits are largely invisible. Imagine continuous visibility from the moment of implantation through long-term outcomes — without changing the surgical workflow, without adding hardware to the patient’s home, and without asking surgeons to learn a new clinical platform.
Our smart knee implant fills the gap.
Our Approach
Built on cleared platform technology.
Our work leverages FDA-cleared platform technology rather than starting from a blank sheet. This allows us to advance the field of intelligent orthopedic implants on a faster regulatory path while maintaining the rigor that implantable medical devices require. We design our systems to integrate into existing surgical procedures without disruption — surgeons follow their established techniques, and patients receive standard care augmented by continuous post-operative insight.

Our Philosophy
Data, not diagnosis.
Sensor data supports surgeon decision-making. Diagnostic interpretation, treatment decisions, and patient communication remain with the surgeon. We build implants that make the surgeon’s existing workflow better — not technology that competes for clinical authority. Our positioning aligns with the regulatory framework for sensor-aided clinical decision support, the practical realities of surgical practice, and the long-standing relationship between surgeons and their patients.
