What is it?
Zimmer Biomet ROSA Knee is a robotic surgical assistant for total knee arthroplasty, using intraoperative bone registration rather than pre-operative CT scanning for surgical planning and robotic arm guidance.
Who is it for?
- Orthopaedic surgeons performing total knee replacement who prefer to avoid pre-operative CT
- Hospitals adding robotic knee surgery capability at lower capital cost than premium platforms
- Zimmer Biomet implant users seeking integrated robotic and implant ecosystem
- Ambulatory surgery centres requiring a compact robotic knee system
Key specs
- Planning: intraoperative bone registration
- CT requirement: none
- Guidance: robotic arm for bone cutting
- Tracking: real-time leg alignment
- Implants: Zimmer Biomet systems
- Platform: also available for spine (ROSA Spine)
How it compares
Vs Stryker Mako: ROSA Knee eliminates pre-operative CT, reducing patient radiation and pre-surgical cost. Mako's CT-based planning provides more detailed pre-surgical anatomy modelling. Both offer similar intraoperative robotic guidance. Mako has a larger installed base.
Limitations
- Intraoperative registration less detailed than CT-based pre-operative planning
- Limited to Zimmer Biomet implant systems
- Smaller installed base and shorter clinical evidence record than Mako
- ROSA platform shared with spine — less specialised than dedicated knee systems
FAQ
How much does the Zimmer Biomet ROSA Knee cost?
Zimmer Biomet ROSA Knee pricing is available through Zimmer Biomet's sales network. Robotic surgery systems in this class are typically priced at $800,000–$1.2M. Contact Zimmer Biomet for formal pricing.
What is the ROSA Knee used for?
ROSA Knee is a robotic surgical assistant for total knee arthroplasty, using intraoperative registration instead of pre-operative CT to plan and guide bone cuts for precise knee implant alignment.
What are the key specs of the ROSA Knee?
ROSA Knee uses intraoperative bone registration (no pre-operative CT required), provides robotic arm guidance for bone cutting, tracks leg alignment in real-time, and is compatible with Zimmer Biomet knee implant systems.
Who is the ROSA Knee designed for?
ROSA Knee is designed for orthopaedic surgeons performing total knee replacement who want robotic precision without requiring patients to undergo a pre-operative CT scan.
What is the key difference between ROSA Knee and Stryker Mako?
ROSA Knee's key differentiator is intraoperative registration — no pre-operative CT is needed, reducing patient radiation exposure and pre-surgical cost. Mako requires a CT scan before surgery for its 3D planning model.
