Key features
- Autonomous bone cutting (not haptic-guided)
- CT-based pre-operative 3D surgical planning
- Sub-millimetre bone preparation precision
- Total knee and hip replacement certified
- FDA cleared
- Reproducible execution independent of surgeon manual variation
- Alternative architecture to dominant haptic-guidance category
What is it?
The TSolution One is an autonomous orthopaedic surgical robot for total knee arthroplasty (TKA) and total hip arthroplasty (THA). It uses pre-operative CT imaging to build a 3D bone model and surgical plan, then executes bone cuts autonomously with the robotic arm — the surgeon confirms the plan and oversees execution but does not manually guide the cutting tool.
Who is it for?
Orthopaedic surgery centres and academic medical centres performing high volumes of total knee and hip replacements seeking maximum bone preparation precision and reproducibility. Surgeons who prefer autonomous execution over haptic guidance for consistent implant positioning. Hospitals evaluating alternatives to the dominant haptic-guidance platforms (Stryker Mako, Smith+Nephew CORI).
Key specs
- Applications: Total knee arthroplasty (TKA), total hip arthroplasty (THA)
- Bone preparation: Autonomous robotic cutting (not haptic-guided)
- Planning: Pre-operative CT-based 3D planning
- Precision: Sub-millimetre bone cut execution
- Regulatory: FDA cleared
- Approach: Autonomous execution vs haptic-guidance competitors
- Origin: US
Autonomous vs haptic-guided: the key distinction
Most orthopaedic robots (Stryker Mako, Smith+Nephew CORI, Zimmer Biomet Rosa) are haptic-guided: the surgeon physically moves the robotic arm while the system constrains motion to a virtual boundary. TSolution One autonomously executes cuts: the robot moves independently while the surgeon monitors. Think Surgical argues autonomous execution eliminates human variability; critics note autonomous execution reduces intraoperative adaptability.
How it compares
TSolution One competes with Stryker Mako (dominant market share, haptic-guidance), Smith+Nephew CORI (imageless haptic), and Zimmer Biomet Rosa Knee. Think Surgical's autonomous approach is the primary technical differentiator; Stryker Mako's market penetration (5,000+ systems) represents the dominant commercial standard.
Limitations
- Requires pre-operative CT scan (imaging cost and workflow)
- Autonomous execution leaves less intraoperative adaptability than haptic systems
- Smaller installed base than Stryker Mako
- Surgeon training required for autonomous execution workflow (different from haptic-guidance)
FAQ
What is the difference between TSolution One and Stryker Mako?
Stryker Mako is haptic-guided: the surgeon physically drives the robotic arm while the system restricts motion to virtual boundaries. TSolution One is autonomous: the robot executes bone cuts independently based on the pre-operative plan while the surgeon monitors. Think Surgical argues autonomous execution is more precise and reproducible; Mako's approach preserves intraoperative surgeon control.
Does TSolution One require a pre-operative CT scan?
Yes. TSolution One's surgical planning is based on CT imaging to build a 3D bone model for plan creation. This adds imaging cost and workflow steps versus imageless systems (e.g. Smith+Nephew CORI).
Is TSolution One FDA cleared?
Yes. TSolution One has FDA clearance for total knee arthroplasty and total hip arthroplasty applications.
