How Much Does a Private Knee Replacement Cost in the UK? (2026 Prices)

UK ranges come from LaingBuisson's self-pay market data (collected May 2025); the Circle Health Group figure is from its own price page. The Poland figure is our partner hospital's orthopaedic price list (July 2026), converted at €1 = £0.86.

Circle Health Group puts the typical UK price at £12,000 – £16,000, with an average of about £14,000.

Fixed-price ("package") prices at UK private hospitals normally cover:

• the operation itself and the implant
• the surgeon's and anaesthetist's fees
• your hospital stay, usually in a private room
• follow-up appointments and a course of physiotherapy (in most packages)

What they usually don't include:

• your first consultation with the surgeon — from about £200 at Circle, and typically £250–£350 elsewhere
• scans and tests needed to decide whether you need surgery (X-rays, MRI)
• extra nights if your recovery is slower than planned, unless the package says otherwise

So the realistic total is the package price plus a few hundred pounds before you are even booked in. Always ask for the full list of exclusions in writing.

The same operation can differ by several thousand pounds depending on:

• Location. London and the South East are usually the most expensive.
• Type of replacement. A partial (unicompartmental) knee is not always cheaper than a total knee.
• Implant. Cementless, "anti-allergy" (nickel-free) or premium designs cost more.
• Technique. Robot-assisted surgery is often priced higher.
• Your health. A higher anaesthetic risk or other conditions can mean a longer stay and a higher quote.
• The surgeon. Some consultants set their own fees on top of the hospital's package.

Because of this, the only price that matters is your written quote. Compare quotes line by line, not headline figures.

Prices also move inside a single group: Circle Health Group advertises a national price from £13,020, while a competitor's published comparison puts Circle Bath at £15,985 for the same operation. We list what each one publishes in private knee replacement cost by hospital group.

If you have private medical insurance, check whether knee replacement is covered and what your excess is — joint problems that started before you took out the policy are often excluded.

Many UK hospital groups offer 0% or low-interest finance for self-pay patients. Read the total amount repayable, not just the monthly figure.

On the NHS, a knee replacement costs you nothing — but you may wait a long time. At the end of August 2026, 843,419 trauma and orthopaedic pathways were waiting to start treatment in England — the largest waiting list of any specialty — and only 61.1% had been waiting less than 18 weeks, against an NHS standard of 92%.

Waiting times vary widely between hospitals. Our guide to NHS hip and knee replacement waiting times explains how to check your local wait and what rights you have to move hospital.

A growing number of UK patients self-fund surgery in another European country instead of paying UK private prices. Our partner is a private surgical hospital in Jelenia Góra, south-west Poland, operating under EU medical regulation for around 20 years.

Included in the knee package: pre-operative diagnostics, general anaesthesia, the operation and implant (Zimmer Biomet, DePuy Synthes or Enovis LIMA), three days on the hospital ward, up to seven outpatient physiotherapy sessions after discharge, a hospital patient coordinator and a post-operative consultation with your rehabilitation plan.

Not included: flights, hotel, and a private room (available at extra cost). Prices are billed in euros, so the sterling figure moves with the exchange rate.

Compared with a UK package from about £13,020, the hospital price is around £5,600 lower before travel. The hospital name, your surgeon and the exact implant are named in your written plan before you pay anything.

The operation is the big number, but plan for the whole trip:

A 20% deposit secures your date and is paid directly to the hospital. If you cancel for an important reason at least 72 hours before surgery, the deposit is refunded within 14 days.
