What does robotic knee replacement involve?
Robotic knee replacement is a knee replacement in which the surgeon uses a computer plan and a robotic system to help position the bone cuts and implant. The surgeon performs the operation. The robot does not operate by itself.
The steps
- Imaging. A CT scan, or a mapping of the joint during surgery, creates a 3D model. The method depends on the system.
- Planning. The surgeon uses the model to plan implant size, position and alignment.
- Bone preparation. The surgeon controls the instrument. The system helps keep it within the planned boundary.
- Implant. The surgeon fits the implant and checks movement and stability.
Risks
Robotic assistance does not remove the risks of knee replacement. These include infection, blood clots, stiffness, continued pain, and implant wear or loosening.
Questions to ask
- Which approach suits my knee, and why?
- What are the risks of each approach for me?
- What is the cost difference?
