Knee Replacement Private Cost Calculator

How much does a private knee replacement cost in the UK?

A private total knee replacement in the UK typically costs around £13,000 to £18,000 as a fixed-price, self-pay package. A partial (unicompartmental) knee replacement is usually cheaper – commonly in the region of £10,000 to £14,000 – because the operation replaces only one compartment of the joint and the hospital stay is shorter. These figures are estimates: the price you are actually quoted depends on the hospital group, the city, the surgeon and anaesthetist fees, the implant used and how long you stay in. On top of the headline package, most people also pay for an initial consultation, diagnostic imaging and some extra physiotherapy, which is exactly what this calculator adds up for you. Knee replacement is also available free on the NHS if a consultant agrees you need it – the trade-off is the waiting list in your area, which you can check on the NHS My Planned Care service.

What drives the price up or down

• Total vs partial. A partial knee replacement is a smaller operation with a shorter stay, so it usually comes in a few thousand pounds cheaper. Suitability depends on where the arthritis is – roughly, damage confined to one side of the knee – and the surgeon decides after examining you and reviewing imaging.
• Location. Hospitals in London and the South East commonly quote around 10–15% more than the same operation in the North of England, Scotland, Wales or Northern Ireland. Some self-payers deliberately travel for a lower quote.
• Surgeon and anaesthetist fees. In a true fixed-price package these are bundled in; where they are quoted separately, they can move the total noticeably. Ask whether the quote is genuinely all-inclusive.
• The implant. Different prosthesis brands and designs (including cemented vs uncemented, or robotic-arm-assisted surgery) carry different costs. Robotic assistance often adds to the package price.
• Length of stay. Most packages assume two to four nights. If you need longer for medical reasons, check whether extra nights are covered by the fixed price or billed on top.

What a fixed-price package usually includes

“Fixed price” does not mean “everything”. A typical self-pay knee replacement package covers the pre-operative assessment, the surgeon's and anaesthetist's fees, the operating theatre, the implant itself, your hospital stay with nursing care, take-home medication and one or two standard follow-up appointments. Commonly excluded – and worth budgeting for – are the initial consultation (typically £150–£250), diagnostic imaging before you are accepted for surgery (an X-ray at roughly £70–£150, or an MRI at around £250–£450), extended physiotherapy beyond the first session or two, and treatment for complications after the guarantee period. Most reputable hospitals publish what happens if you need readmission or revision within a set window – read that section before comparing prices.

Physiotherapy: the cost people forget

The success of a knee replacement depends heavily on rehabilitation. The NHS overview of knee replacement recovery stresses regular exercises in the weeks after surgery. Packages often include only an initial physio session or a short course, after which private physiotherapy typically runs at £40–£70 per session. Many self-pay patients budget for 6 to 12 extra sessions over the first couple of months – roughly £250 to £850 – which is why the calculator asks about it separately. If money is tight, ask your surgical team whether NHS physiotherapy or a supervised home exercise plan is realistic in your area.

One worked example

Margaret, 68, is quoted a £14,500 fixed-price total knee replacement package at a hospital in Manchester. Before being listed she pays a £200 consultation and a £100 X-ray. Her package includes one physio session; she books eight more at £55 each (£440) at a local clinic. Her realistic all-in cost is therefore about £15,240 – roughly £750 more than the headline package price. Had her arthritis been confined to the inner compartment and a partial replacement been suitable, an equivalent package at the same hospital might have been quoted at around £11,500–£12,500, though only her surgeon could confirm that option.

Your options for paying – and the NHS route

• Self-pay fixed-price package. The most common private route: one price agreed in writing before surgery. Always ask for the itemised inclusions list.
• Medical finance. Many hospital groups offer loans over one to five years. Check the APR and total repayable – interest can add a meaningful amount to a five-figure procedure.
• Private medical insurance. If your arthritis developed after the policy started, insurance will often cover the operation subject to GP referral, pre-authorisation and any excess. Pre-existing joint problems are frequently excluded – check your policy wording first.
• The NHS. Knee replacement is free on the NHS when clinically appropriate. Waiting times vary a lot by trust and by area; compare your local wait on My Planned Care before deciding whether paying privately is worth it to you.

Mistakes to avoid when comparing quotes

• Comparing headline prices, not inclusions. A £13,500 quote that excludes imaging, physio and follow-ups can cost more overall than a £15,000 genuinely all-inclusive package.
• Ignoring the aftercare and revision policy. Ask what happens – and who pays – if you are readmitted with a complication in the first month, or if the implant needs early revision.
• Choosing on price alone. Ask the surgeon how many knee replacements they perform each year and what their outcomes are like. Experience matters for a joint you will live with for 15–25 years.
• Forgetting recovery costs. Extra physio, time off work, help at home and travel to follow-ups all sit outside the package price.
• Not asking about the implant. You are entitled to know which prosthesis brand and model is planned and why the surgeon prefers it.

Frequently asked questions

How much does a private knee replacement cost in the UK?

A private total knee replacement typically costs around £13,000 to £18,000 in the UK as a fixed-price package, depending on the hospital, city and surgeon. These are estimates – always confirm a written quote with the hospital.

Is a partial knee replacement cheaper than a total?

Yes. A partial (unicompartmental) knee replacement usually costs a few thousand pounds less – roughly £10,000 to £14,000 privately – because the operation is smaller and the hospital stay shorter. Only patients whose arthritis is confined to one compartment of the knee are suitable, and that decision rests with the surgeon.

What does a fixed-price knee replacement package include?

Most packages cover the surgeon's and anaesthetist's fees, the theatre, the implant, a two-to-four-night hospital stay, nursing care and standard follow-up. The initial consultation, diagnostic imaging and extended physiotherapy are often charged separately, so check the inclusions line by line.

Can I have a knee replacement on the NHS instead?

Yes – knee replacement is free on the NHS if your GP and an orthopaedic consultant agree you need it, but waiting times vary widely by area. You can check typical local waits on the NHS My Planned Care site before deciding whether to self-pay.

How much is physiotherapy after a knee replacement?

Private physiotherapy typically costs around £40 to £70 per session, and many people have 6 to 12 sessions over the first weeks of recovery. Some packages include a limited number of sessions; extra ones are billed separately.

Does private medical insurance cover knee replacement?

Often, yes – if the arthritis developed after the policy started and is not excluded as a pre-existing condition. You will normally need a GP referral and pre-authorisation from the insurer, and you may still pay an excess.

How long does recovery from a knee replacement take?

Most people are walking with support within a day or two and driving again after several weeks, but a full recovery commonly takes months and depends on doing the physiotherapy exercises. Your surgical team will give you a personal timescale – this page is general information, not medical advice.
