Robotic-assisted knee replacement cost in the UK: what you pay privately (2026)

A private robotic-assisted knee replacement uses a robotic system to help plan and execute bone cuts, and is offered as a premium option at some hospitals, mostly for total or partial knee replacement.

Hospital price pages give a first idea of scale. The robotic-assisted knee replacement entries we retrieved sat between £17,160 to £18,210; the rows below show which hospital and which variant each figure refers to.

None of these numbers is an offer to treat. Providers confirm a final price after assessment, and consultant or anaesthetist fees may be set separately.

The surgeon uses a system that either relies on a scan-based plan or maps the knee during surgery, and the robot constrains the saw to the planned cuts. The rest of the operation follows the standard steps.

Ask how many robotic operations your surgeon performs and whether you could receive the same implant by conventional means for less.

A single guide figure for robotic-assisted knee replacement can mislead, because the final amount depends on factors like these.

• Technology premium: The Cherwell lists robotic-assisted total knee replacement at £18,210 against £17,160 for its standard knee replacement.

• Planning imaging: some systems use a pre-operative CT or intra-operative mapping.

• Implant choice and hospital stay.

• Consultant and anaesthetist fees.

• Hospital pricing: standard knee replacement alone ranges widely across hospitals, so the robotic uplift may be smaller than the gap between hospitals.

Providers define a package differently, so two quotes are only comparable once you line up what each covers. The table lists what is typically in and what is often billed separately for this procedure.

Some insurers fund only the standard operation, so check coverage of the robotic premium.

Insurers often agree a procedure code and a fee ceiling in advance. Self-pay patients should ask whether instalment finance is offered and what the total repayable would be, as the representative rate and terms differ by lender.

Robotic knee replacement is available in some NHS trusts and not routinely everywhere, and the standard operation remains the main NHS option.

NHS care is free at the point of use, and for non-urgent consultant-led treatment the standard is 18 weeks from referral. You also have the right to choose where you are referred in England. Local waits differ, so ask what applies near you.

Recovery follows the same pattern as conventional knee replacement, with physiotherapy over months.

No one plans for things to go wrong, but a short conversation about extra costs now can save difficulty later.

• The risks of knee replacement such as stiffness, infection and clots remain, and robotic assistance does not remove them.

• Premium technology does not guarantee a better long-term outcome, so ask what the surgeon expects it to change.

Quotes only compare fairly when they cover the same things. Put these questions to every provider you approach.

• What is the exact premium for robotic assistance?

• Which robotic system is used, and does it need a CT?

• How many robotic knees does my surgeon perform?

• What would a conventional operation cost?

• Will I receive one price covering the hospital, the consultant and the anaesthetic, or several bills from different parties?
