UK Patients Facing a Hip or Knee Replacement: NHS Wait, UK Private or Abroad?

Three routes, three sets of trade-offs. Here is how a UK patient can line them up using the NHS's own waiting figures, PHIN's published self-pay prices, and the rules on treatment outside Europe.

If you are in the UK and your GP or consultant has raised a hip or knee replacement, you are really choosing among three routes: wait for NHS treatment, pay for surgery at a UK private hospital, or pay for surgery in another country. Each one swaps something for something else. Time, money, continuity of care and legal protection all move depending on which you pick.

This page lines the three up using official sources. It is not medical advice, and whether you need surgery, and how soon, is for an orthopaedic surgeon who has examined you.

Route one: the NHS waiting list

In England, planned hospital treatment is measured against the referral to treatment (RTT) standard, which says more than 92% of patients should start treatment within 18 weeks of referral. The NHS England RTT statistical notice for June 2026, published in August 2026, reported:

• About 7.3 million pathways on the overall waiting list.
• 65.8% of patients waiting within 18 weeks, well short of the 92% standard.
• A median wait of 11.9 weeks across all specialties.
• For trauma and orthopaedics specifically, 829,590 incomplete pathways, with 60.9% within 18 weeks.

Two points help put those numbers in context. First, trauma and orthopaedics covers far more than joint replacement, so the specialty figure is a backdrop rather than a forecast for your hip or knee. Second, the notice covers England only. Scotland, Wales and Northern Ireland publish their own waiting statistics.

What the NHS route gives you

The obvious advantage is cost: treatment is free at the point of use. The less obvious one is continuity. The same system that operates on you handles your follow-up appointments, physiotherapy referrals, X-rays and any complications. You never have to translate records, hand over implant details from abroad or explain what was done by someone your GP has never heard of.

How to make the wait work for you

• Ask your hospital for its own current estimate for your procedure, rather than relying on national figures.
• Ask your GP whether another hospital might be able to treat you sooner.
• Tell your GP or consultant if your pain or mobility worsens, so your priority can be reviewed.
• Use the time to build strength, sort out dental problems, and get long-term conditions as stable as possible, all things surgeons look for before operating.

Route two: UK private self-pay

The Private Healthcare Information Network publishes average self-pay package prices by city. Its PHIN average package prices page (March 2026 data) shows, across 17 UK cities:

PHIN says a package usually covers the surgeon, the anaesthetist and the hospital fees, but may leave out the first consultation and extras such as physiotherapy. It describes the figures as a guide only, notes prices may have changed since they were collected, and advises asking the hospital to confirm in writing what is included before booking. Treat these averages as a starting point for your own quotes rather than a price list.

What the UK private route gives you

You stay within UK regulation. PHIN points out that UK hospitals are inspected by the Care Quality Commission and must submit patient safety information. Your surgeon is on the GMC register, and you can go back to the same hospital for follow-up without a flight. If something goes wrong, you are dealing with a provider and complaints process in the same legal system as you.

Questions to put to any UK private quote

• Does the price include the first consultation and any pre-operative tests?
• How many physiotherapy sessions are included after discharge?
• What happens, and what does it cost, if I need an extra night or a readmission?
• Which implant will be used, and will I get its details in writing?

Route three: surgery abroad

Going abroad is where the rules most often surprise people. The NHS guidance on going abroad for treatment (reviewed 2023) makes several points UK patients should know before they look at overseas prices:

• The S2 route, a funding arrangement with state healthcare in some European countries, needs prior authorisation and applies within Europe only.
• The EU directive reimbursement route only covers treatment that started or was approved before the end of 2020.
• Neither route applies to treatment outside Europe. For non-European treatment the NHS points you to your local integrated care board.
• A GHIC or EHIC does not cover planned treatment.
• Most standard travel insurance does not cover planned treatment abroad.
• The NHS is not liable for negligence or treatment failure abroad.

For a patient looking at Colombia or anywhere else outside Europe, the practical reading is that surgery abroad is self-funded, and you should assume the insurance and legal arrangements are yours to sort out.

The aftercare question

PHIN's guidance on treatment abroad (2026) adds detail on the return home. It says the NHS covers life-threatening emergencies after overseas treatment, warns that return appointments can mean extra flights and hotels, notes that remote follow-up cannot replace an in-person examination, and reminds patients that air travel after a procedure can raise the risk of deep vein thrombosis. It also cautions that clinic guarantees may be hard to use in practice once you are back in the UK.

For a joint replacement, where you will usually need physiotherapy and follow-up X-rays, that means deciding before you go who will see you at home. Speak to your GP early; the NHS guidance recommends it before any final decision.

Side by side

If you are leaning towards abroad

A few checks separate a thought-through plan from a hopeful one.

Verify the people, not just the building

PHIN suggests checking a surgeon's registration on the national register of the country concerned, in the same way you would use the GMC list at home. In Colombia, the professional register is ReTHUS. Ask for the surgeon's experience with your specific joint, and whether they will review your X-rays before quoting.

Get the insurance answer in writing

Because standard travel policies generally exclude planned procedures, ask any insurer you approach to confirm, in writing, whether complications of planned surgery are covered and whether that includes getting you home.

Plan the records hand-off

Before you leave the hospital abroad, you will want an English discharge summary, the operation note, the implant make and model, and your imaging. Your GP and any UK physiotherapist will need them, and so will any surgeon who treats the joint in future.

Price the whole trip

Compare an overseas quote against a UK private quote only after adding flights, accommodation for the period your surgeon wants you nearby, a companion's costs, time off work, and physiotherapy at home. PHIN specifically flags extended hotel stays, flight changes and lost wages as costs patients overlook.

If you live in Scotland, Wales or Northern Ireland

The figures above are for England. Health is devolved, so the other UK nations run their own waiting lists, publish their own statistics and set their own policies on treatment elsewhere. Look for your nation's official waiting time statistics and ask your local health board, rather than relying on English figures. The general NHS points about planned treatment abroad, insurance and aftercare are still worth reading, but confirm the local rules with your GP or health board.

A simple way to decide

Write down three things: how long your NHS hospital says you will wait, what a UK private hospital quotes in writing for the full package, and what an overseas provider quotes plus every travel and aftercare cost. Then ask yourself which risks you are willing to own. Some patients will happily wait for continuity and no bill. Others will pay a UK private hospital for speed while staying close to home. A smaller group will decide the savings or the timing abroad are worth managing the follow-up themselves. All three can be reasonable choices when they are made with the real numbers in front of you.
