Side by side
- Alignment accuracy: Robotic — accurate to fractions of a millimetre against a pre-built 3D plan. Traditional — relies on the surgeon's manual instrumentation and experience, which is excellent in skilled hands but has more natural variability
- Soft-tissue handling: Robotic — typically less soft-tissue trauma since cuts are guided precisely. Traditional — slightly more reliant on jigs that can disturb surrounding tissue
- Recovery speed: Robotic — many patients report quicker early mobilisation. Traditional — recovery is still good, just on average a touch slower in the first few weeks for some patients
- Cost: Robotic — approximately ₹2.5–3 lakh per knee, due to the technology usage fee. Traditional — approximately ₹1.5–2 lakh per knee depending on the implant chosen, and a well-established, time-tested option. We quote both honestly so you can weigh the difference against your own priorities
- Long-term outcome: Both achieve excellent, durable results (implants lasting 20–25+ years) in the hands of an experienced joint replacement surgeon — the surgeon's skill matters more than the tool
Image-based vs. imageless robotic systems
Robotic knee replacement itself comes in two main forms, and the choice affects both planning and cost. Image-based systems use a CT scan taken before surgery to build a precise 3D plan, which adds the cost of that scan. Imageless systems map your knee in real time during the operation using surface and motion tracking, skipping the pre-op CT scan and its cost while still achieving robotic-level alignment accuracy for the great majority of knees. We recommend whichever genuinely suits your case — not the one that costs more.
Disadvantages of robotic knee replacement — the honest version
- Higher cost than conventional surgery
- Slightly longer operative time in some cases, due to the additional planning and registration steps
- Requires specific equipment and surgeon training — not available everywhere
- For straightforward, well-aligned knees in experienced hands, the outcome difference versus traditional surgery can be modest
Who is not a good candidate for robotic knee replacement?
Robotic assistance is not strictly necessary for every patient. Some prior knee implants, certain hardware from old fractures, or specific anatomical factors can make a conventional approach more practical in a minority of cases. This is assessed individually — it is not a reason to avoid evaluation, simply a factor in planning the right approach for your knee.
Our honest recommendation
Robotic-assisted surgery is our preferred approach for most knee replacements because of the alignment precision it offers, but it is a tool, not a guarantee — surgical experience and post-operative rehabilitation remain the biggest drivers of outcome either way. We discuss both options plainly for your specific knee rather than defaulting to whichever is most profitable to offer.
