If your vet has just mentioned a "cruciate" — or you've heard a sudden yelp and your dog is now hopping on three legs — you're in the middle of one of the most common, and most expensive, orthopaedic problems in UK dogs. The good news is that the prognosis is excellent. The harder news is that you're now facing a decision between several surgical techniques, prices that range from around £2,500 to over £6,000, and at least four months of careful rehab.
This guide is written to do two things: take the jargon out of the conversation you're about to have with your vet, and give you realistic UK prices so you can plan without being blindsided.
In short — UK cruciate surgery costs in 2026
- • TPLO (Tibial Plateau Levelling Osteotomy): typically £3,500–£5,500 per leg
- • TTA (Tibial Tuberosity Advancement): typically £3,000–£4,800 per leg
- • Lateral suture / extracapsular repair: typically £1,500–£2,800 per leg
- • Sedated X-rays + diagnosis: £300–£700
- • Hydrotherapy course (6–10 sessions): £200–£500
- • Conservative (non-surgical) management: £400–£1,200 over the first year
Figures reflect 2026 UK prices including pre-op bloods, anaesthesia, implants, hospitalisation, post-op X-rays and the standard re-checks. Referral hospitals (Fitzpatrick, Langford, Davies, Eastcott, NDSR) sit at the upper end; first-opinion orthopaedic surgeons working in independent practices often sit at or below the middle of these ranges.
What the cruciate ligament does — and why dogs tear it
Your dog's cranial cruciate ligament (CCL) is the equivalent of the human anterior cruciate ligament (ACL). It sits inside the knee (stifle) joint and stops the shin bone (tibia) sliding forward when the dog bears weight. When it tears, the joint becomes unstable and painful, the meniscus often gets caught and damaged, and arthritis sets in within weeks if it isn't stabilised.
In humans, ACL injuries are usually traumatic — a skier catches an edge. In dogs it's different: most cruciate ruptures are degenerative. The ligament gradually weakens over months or years and then gives way during something ordinary like jumping off the sofa. That's why the second leg often goes within two years — the underlying weakness is bilateral.
Breeds most affected
Labradors, Rottweilers, Newfoundlands, Staffies, Boxers, Mastiffs and Springers are over-represented. Overweight dogs of any breed are at higher risk. Small dogs tear cruciates too — but they often do well with smaller, cheaper procedures.
How vets diagnose it
A vet experienced in orthopaedics can usually make the diagnosis on a conscious clinical exam — the cranial drawer test and tibial thrust test feel for that abnormal forward slide. But a definitive diagnosis, and the measurements needed to plan surgery, require sedated X-rays of both stifles.
- Consultation: £35–£75 at most UK practices.
- Sedated orthopaedic exam + bilateral stifle X-rays: £300–£700.
- MRI or arthroscopy (referral hospitals only): £1,200–£2,500, used in complex or partial-tear cases.
The three main surgical options
1. TPLO — Tibial Plateau Levelling Osteotomy
The current gold standard for medium and large dogs. The surgeon cuts the top of the tibia, rotates it to a flatter angle, and fixes it with a titanium plate. This eliminates the forward-sliding force entirely — the knee no longer needs the ligament. Outcomes are excellent in around 90% of cases.
- Typical UK cost: £3,500–£5,500 all-in (some referral hospitals £5,500–£7,000).
- Recovery: 12 weeks of strict rest, then a graded return; bone healing confirmed at 8-week post-op X-rays.
- Best for: dogs over ~15kg, working/active dogs, full ruptures.
2. TTA — Tibial Tuberosity Advancement
An alternative geometry-changing surgery — the front of the tibia is advanced forward and fixed with a titanium cage. Slightly less invasive than TPLO and historically a bit cheaper, with broadly comparable outcomes in carefully selected cases.
- Typical UK cost: £3,000–£4,800.
- Recovery: similar to TPLO — 12 weeks restricted.
- Best for: dogs with a suitable tibial conformation; surgeon preference matters here.
3. Lateral suture (extracapsular repair)
A heavy nylon-style suture is placed around the outside of the joint to mimic the failed ligament while scar tissue forms a new stabiliser. Cheaper, simpler, no bone cut.
- Typical UK cost: £1,500–£2,800.
- Recovery: 8–12 weeks restricted; arthritis progression slightly higher than TPLO in large dogs.
- Best for: dogs under ~15–20kg, older or less active dogs, owners on a tight budget.
When is conservative (non-surgical) management appropriate?
For small dogs (under 10kg), elderly dogs, or dogs with significant anaesthetic risk, a strict 8–12 week rest plan plus pain relief, weight loss, hydrotherapy and physio can produce a functional outcome — but with more arthritis than a surgical case. Expect to spend £400–£1,200 in the first year on consults, pain relief and physio. Many large dogs managed conservatively struggle long-term, so this isn't usually a first-line choice for them.
What's in the price — what to check before you say yes
Cruciate quotes vary wildly because practices include different things. Always ask whether the quote covers:
- Pre-op bloods and ECG
- The anaesthetic and the implants themselves (plates and screws are expensive)
- Hospitalisation and overnight care
- Post-op pain relief to take home
- The 6 and 12-week re-checks and X-rays
- Hydrotherapy or physio referrals
- Complication cover (what if the plate needs replacing?)
A £3,200 quote that covers everything is often better value than a £2,700 quote that bills extras separately.
Recovery — the part owners underestimate
Getting the surgery right is only half of it. The 12-week recovery is what actually determines the outcome:
- Weeks 1–2: strict crate rest, lead walks only for toileting, pain relief.
- Weeks 3–6: short 5-minute lead walks building gradually; sling support on stairs.
- Weeks 7–12: longer controlled walks; hydrotherapy starts around week 4–6.
- Months 4–6: graduated return to off-lead exercise after vet sign-off.
Hydrotherapy (£25–£45 per session, usually 6–10 sessions) is the single best investment in long-term outcome. Physio assessment (£60–£90) at week 3 is also worthwhile.
The "second leg" question
Studies consistently show that 40–60% of dogs who tear one cruciate will tear the other within two years. That doesn't mean it will happen — but you should budget as if it might, especially in Labradors and Rottweilers. Insurance is your friend here; see below.
Insurance and how to pay for it
- Lifetime insurance with a per-condition limit of £7,000+ usually covers TPLO comfortably, including hydrotherapy. Cruciate disease is treated as one condition across both legs by most insurers, so once you've hit your limit on the first leg, the second is on you. Read the wording.
- Pre-existing exclusion warning: if your dog had any prior lameness in either hind leg, expect insurers to scrutinise the claim. Get pre-authorisation in writing before surgery.
- No insurance? Many surgeons offer fixed-price packages (Kentdale, Eastcott, some Vets4Pets referral centres) and most independent practices will quote in writing on request. Vetsure and CareCredit-style finance plans through Payl8r and DivideBuy are increasingly common.
- Charitable help — PDSA, RSPCA and Blue Cross may help with diagnostics and pain relief for owners on qualifying benefits; surgical referral funding is rare but worth asking about.

Questions to ask any surgeon before booking
- Are you an RCVS Advanced Practitioner or Specialist in Small Animal Surgery? (Check the RCVS register.)
- How many TPLO/TTA procedures do you do per year?
- What is your complication rate, and what's included if I have to come back?
- Will the same surgeon do the operation and the follow-ups?
- Is hydrotherapy included or referred?
- Can I have an itemised written quote, including implants?
A confident, transparent answer to all six is what you're looking for.
Frequently asked questions
Does my dog definitely need surgery?
For most medium and large dogs with a full rupture, yes — surgery gives the best long-term function. Small dogs, very old dogs, or dogs with significant anaesthetic risk can do reasonably well on conservative management. A second opinion from an orthopaedic surgeon is reasonable and most vets will support it.
Is TPLO really worth twice the price of a lateral suture?
For an active 30kg Labrador, the evidence says yes — better function, less arthritis, faster return to normal life. For a 9kg terrier, a well-done lateral suture often gets the same result for a fraction of the cost.
Can I have it done by my normal vet, or do I need a referral hospital?
Many first-opinion practices have an RCVS Advanced Practitioner in surgery who does TPLOs to a high standard — and they're often £1,000–£2,000 cheaper than the big referral hospitals. The question to ask is about case volume, not building size.
Will my dog walk normally again?
Around 90% of dogs return to normal or near-normal function after TPLO. The remaining 10% have some residual stiffness, especially in cold weather. Weight management matters more than almost anything else.
What about regenerative treatments — stem cells, PRP?
Useful adjuncts in some chronic or partial-tear cases, but not yet a substitute for stabilisation in a full rupture. Ask your surgeon whether they'd recommend it in your specific case.
How do I find a surgeon in my area?
Start by asking your own vet for a referral list and quotes from two or three options. You can also compare independent and referral practices in your area on our homepage and check the RCVS Find a Vet register for advanced practitioner credentials.
