Quick answer: Luxating patella surgery for a dog in the UK typically costs £2,000 to £4,000 per knee at private practices, although some not-for-profit clinics offer fixed prices from around £1,000 plus X-rays. Surgery is usually recommended for grade 3 and 4 luxations, and sometimes grade 2 if it causes problems. Around half of affected dogs have it in both knees. Insurance usually covers it if no signs appeared before the policy started, but bilateral and hereditary wording, and low vet fee limits, often reduce what you get back.
A luxating patella is a kneecap that slips out of its groove. It is especially common in small breeds. This guide covers what surgery costs, when it’s needed and how to get the most from your insurance.
How much does luxating patella surgery cost?
| Where | Typical cost | Notes |
|---|---|---|
| Not-for-profit clinic example | Fixed price of £1,045, plus £430 for X-rays if needed | Animal Trust, a not-for-profit vet group; CT, when needed, costs extra |
| Typical private practice | £2,000 to £4,000 per knee | Depends on grade, technique, dog size and location |
| Both knees | Roughly double | Operations are usually done separately |
Prices vary widely. In one owner’s account on a UK forum, their vet quoted around £4,000 per leg for a dog with grade 3 luxation in both knees, after £850 of X-rays, while their policy only covered £2,000 a year. It is worth asking more than one practice for an estimate for planned surgery.
Which grades need surgery?
Luxating patella is graded from 1 (mild, occasional) to 4 (the kneecap is permanently out of place). Animal Trust typically recommends surgery for all grade 3 and 4 luxations, and for grade 2 luxations that cause frequent or significant mobility problems. Milder cases are often managed with weight control, controlled exercise and physiotherapy.
Surgery usually combines several techniques, such as deepening the groove the kneecap sits in and moving the point where the kneecap’s tendon attaches to the shin bone. Your vet will decide which are needed.
Does pet insurance cover luxating patella surgery?
Usually, on accident and illness policies, if your dog showed no signs before cover started or during the waiting period. Watch for three issues:
- Early signs. The classic sign is a skipping gait, where the dog carries a back leg for a few steps. If this appears in the vet notes before the policy began, the condition will normally be excluded. See pre-existing conditions.
- Bilateral and hereditary wording. Because many dogs are affected in both knees, some policies treat both as one condition. Some also have specific wording for hereditary conditions.
- Your vet fee limit. A £2,000 annual limit may not cover one knee at private prices. See how much vet fee cover you need.
What the Ombudsman has said
In a published Financial Ombudsman decision, a dog was recorded with patella luxation within the first 14 days of a new policy, so the insurer excluded it. The ombudsman’s view was that treating any later problem in a different leg as the same condition would only be fair if the underlying issue was the same; an unrelated injury in another leg shouldn’t automatically be excluded. The lesson: insure a small-breed puppy before any signs appear, and challenge exclusions that go further than the vet evidence supports. See what to do if a claim is rejected.
Luxating patella and cruciate problems
A kneecap that keeps slipping puts extra strain on the knee, and some dogs go on to damage the cruciate ligament in the same leg. Ask your vet about the risk, and see cruciate ligament surgery costs.
How to keep costs down
- Insure young. Small breeds prone to luxating patella benefit most from cover taken out before any signs appear.
- Compare estimates for planned surgery, including not-for-profit clinics near you.
- Get pre-approval from your insurer before surgery, and ask how it would treat the other knee.
- Keep your dog lean. Extra weight puts more strain on vulnerable knees.
- If money is tight, talk to your vet about options. See what happens if you can’t pay.
Frequently asked questions
Does grade 2 luxating patella need surgery?
Not always. Many grade 2 cases are managed without surgery, but it may be recommended if the dog is often lame or uncomfortable.
How long is recovery after patella surgery?
Several weeks of restricted exercise, followed by a gradual return to normal activity. Your vet will give you a plan.
Which breeds get luxating patella?
It is most common in small and toy breeds, but larger dogs can be affected too.
Will insurance cover the second knee?
It depends on your policy’s bilateral wording and your dog’s history. Get the insurer’s answer in writing before you claim for the first knee.
Is pet insurance worth it for a small breed?
For breeds prone to knee problems, often yes. See is pet insurance worth it?

- Surgery is usually for grades 3 and 4, and sometimes grade 2.
- Around half of affected dogs have it in both knees.
- Insurance usually pays if there were no earlier signs; check bilateral wording and your limit.
