Robotic & Technology-Assisted Surgery
Robotic assistance allows joint replacement to be planned in three dimensions before the first incision and executed to within a fraction of a degree, a level of accuracy that is difficult to achieve by hand alone.
How it works
A CT scan or intra-operative mapping builds a 3D model of your joint. Paddy Subramanian uses that model to plan implant size, position and alignment specific to your anatomy. During surgery, the robotic arm provides real-time feedback and constrains bone preparation to the plan, protecting the surrounding soft tissues.
The benefits for patients
Robotic assistance can allow more accurate positioning of implants. It is important to be honest about the evidence: studies have not shown a clear difference in outcomes compared with conventional surgery, and it is offered as a precision tool rather than a promise of a better result. Paddy Subramanian has experience with both the VELYS robot and the CORI robot.
Is it right for everyone?
Robotic assistance is a tool, not a substitute for surgical judgement. Paddy Subramanian uses it where it adds precision, and will always explain honestly whether it will make a difference in your case.
Dr Subramanian has been approachable, professional and allowed me to consider what is a major surgery with confidence. All my questions were answered and I felt involved in the decision making. I am now back on my feet with a neat scar. I would recommend him highly to anyone.
