TTA vs TPLO: the cost difference for cruciate surgery in the UK
If your dog has torn its cranial cruciate ligament, you may have been offered a choice between a TPLO and a TTA, two operations that do a similar job in different ways. The names are baffling and the price difference is not always obvious. This guide explains both, and the bills below show what owners actually paid.
The quick version
- TPLO and TTA are both bone-cutting surgeries that stabilise the knee after a cruciate rupture, rather than repairing the torn ligament itself.
- TPLO is the more commonly performed technique today and is often quoted for larger or more active dogs.
- Cruciate surgery can cost up to £5,000, with specialist referral centres at the top end of that range.
- The surgeon's experience, and whether you see a specialist or a first-opinion vet, affects price as much as the technique chosen.
- The CMA found that corporate-owned practices charge 18.3% more on average than independents, so who owns the practice matters as much as where it is.
- Get the quote broken down before you agree to anything: implants, hospital stay and follow-up x-rays are sometimes billed separately from the headline surgical fee.
What people actually paid
The gap: advertised vs actually paid (medians)
People reported paying 5% less than the advertised list price for cruciate / tplo.
List prices are advertised prices; paid figures are what people reported, often for different cases and from a small sample so far. Treat the gap as a signal, not a quote.
Real prices, in people's own words

- £3,500“the surgery was £3.5k, vet carried out the surgery and we took out a payment plan”
- £3,750“For a dog over 25kg it was £3,750”
- £3,750“For a dog over 25kg it was £3,750... covered everything”

Why the price varies so much
Both operations change the mechanics of the knee so the torn ligament is no longer needed, but they cut different bones and use different implants, and that feeds into the cost. The bigger drivers, though, are who does the surgery and who owns the practice. A board-certified orthopaedic specialist working in a referral hospital charges more than a general practice vet who does the occasional cruciate repair, and that difference alone can run into hundreds of pounds. Your dog's size matters too, since larger dogs need bigger implants and longer anaesthetics, and both push the bill up. Aftercare, follow-up x-rays and physiotherapy all add to the headline surgical fee, sometimes as separate line items you only see once the quote is broken down. Ownership plays a real part as well: the CMA found that corporate-owned practices charge 18.3% more on average than independents, and that vet prices overall rose 63% between 2016 and 2023, so the same operation booked today costs a good deal more than it did a decade ago regardless of who is holding the scalpel.
How to pay less
- Ask your vet which technique they recommend and why, then get a second quote from another practice or referral centre before booking.
- Check exactly what the quote includes. Implants, hospital stay, follow-up x-rays and rechecks are sometimes extra, so a low headline price can end up costing more once these are added.
- If cost is a barrier, ask whether a lateral suture technique is suitable, as it is often cheaper for smaller, less active dogs.
- Ask whether the practice is independent or part of a corporate group. The CMA found corporate-owned practices charge 18.3% more on average, so this question alone can change your bill.
- Confirm your insurance limit before booking, because cruciate work can approach £5,000 and eat a whole year's cover in one claim.
- If your dog needs both knees done, ask whether staging the second surgery months apart, rather than booking both at once, changes the price or the payment terms.
Common questions
Is TPLO or TTA better for my dog?
Neither wins outright; they suit different knees. TPLO is the more widely used technique today and is often favoured for large, active dogs, while TTA can be a good fit for certain joint shapes. Your surgeon will recommend one based on your dog's anatomy, size and the x-rays, so ask them to explain the reasoning rather than just the price.
Why does cruciate surgery cost so much?
It is major orthopaedic surgery. You are paying for advanced imaging, a lengthy anaesthetic, specialist implants, the surgeon's training and a careful recovery programme, and cruciate work can reach £5,000, particularly at referral hospitals with specialist teams. Vet prices generally have also risen sharply, up 63% between 2016 and 2023 according to the CMA, so older figures you might have seen quoted are now out of date.
Can I just have the cheaper option?
You can discuss cheaper techniques such as a lateral suture, which can work well for small, less active dogs. For a large, athletic dog, though, a cut-price approach that fails means a second surgery on top of the first bill, so the cheapest option on paper is not always the cheapest in the end. Weigh the upfront saving against the risk of redoing it.
Does it matter if the practice is independent or corporate-owned?
Yes. The CMA found that corporate-owned practices charge 18.3% more on average than independent ones for the same kind of work. It is worth asking directly who owns the practice and comparing that quote against an independent, since the surgical technique itself won't tell you which one you are looking at.
Will my insurance cover the full cost of cruciate surgery?
It depends on your policy limit and whether the condition is already excluded, for example if the other knee has a pre-existing note on your policy. Cruciate surgery can approach £5,000 on its own, which is enough to use up a lower annual limit in one claim, so check your policy documents and any per-condition caps before you book.
Is it worth travelling further for a cheaper quote?
Sometimes, but factor in the whole picture, not just the headline surgical fee. A cheaper quote further away can still cost more once you add repeat travel for follow-up checks, suture removal and physiotherapy, plus the stress of longer journeys for your dog during recovery. Get quotes broken down the same way from each practice so you are comparing like with like.
