Cranial cruciate rupture is the most common orthopedic failure in dogs and one of the most expensive routine surgeries in the market. It is also the condition insurers have written the most defensive language around, because the dogs that tear one ligament are the dogs most likely to tear the second. This page covers what the surgery costs, which of the three waiting clocks applies, and the two clauses that decide whether the invoice becomes a claim.
Is cruciate ligament surgery covered by pet insurance?
Yes, at every accident and illness policy we track, provided the tear and its first symptoms come after enrollment and after the orthopedic waiting period. A cruciate rupture is a surgical injury or a degenerative joint disease depending on how it happened, and both categories sit inside a standard policy.
Accidents and illnesses are marked covered on our coverage map at Embrace, Fetch, Lemonade, Pumpkin, and Trupanion, which is the base a cruciate claim is paid from. The complication is never the main coverage line. It is the timing rules stacked on top of it, and each one is enforced through your pet's veterinary records rather than through anything you declare at checkout.
Three costs around the surgery are worth pricing separately, because they are not automatically inside the claim.
- Rehabilitation. Lemonade sells physical therapy as an add-on rather than including it, and the row is pending at the other partners. Eight to twelve rehabilitation sessions are a normal part of cruciate recovery.
- Prescription joint diets and supplements. That row is marked pending across every partner review we maintain: prescription food and supplement coverage pending policy verification.
- The exam fee for the visit that finds the tear. Some policies include exam fees and some sell them as an add-on, so compare quotes only after the vet-visit fee is priced in on both sides.
What does TPLO or lateral suture surgery cost?
CareCredit puts TPLO at about $3,525 per knee for dogs and $3,453 for cats, and Sustainable Vet Group puts TPLO at most hospitals at $3,500 to $6,000 and up. Billed costs vary widely by region and clinic.
The two common techniques price differently, and the gap is the useful part.
| Line item | What published sources report |
|---|---|
| TPLO, per knee | About $3,525 for dogs and $3,453 for cats (CareCredit); $3,500 to $6,000 and up at most hospitals (Sustainable Vet Group) |
| Lateral suture, surgery only | $1,500 to $3,000 (Sustainable Vet Group) |
| Lateral suture, all in | $2,250 to $5,000 including diagnostics, medication, and rehabilitation (Sustainable Vet Group) |
| Whole cruciate episode | $1,500 to $10,000 (Pawlicy Advisor) |
Sustainable Vet Group breaks the lateral suture episode into its parts, which is the clearest published view of where the money goes.
- Pre-surgical exam and X-rays: $200 to $400
- Surgery: $1,500 to $3,000
- Post-operative medication: $100 to $300
- Suture removal recheck: $50 to $100
- Rehabilitation, eight to twelve sessions: $400 to $1,200
The same source explains the price gap between the two techniques. Lateral suture repair can often be done by a general practitioner rather than a referral surgeon, while TPLO is specialist work. Billed costs vary widely by region and clinic, and Sustainable Vet Group puts numbers on that: surgeons in California and New York charge 30 to 40 percent above the figures above.
One number circulates widely and should not be used as a quote. Healthy Paws reports an average paid claim of $1,056 for cruciate ligament claims in its 2025 claims data. That is what one insurer paid on an average claim after deductibles, reimbursement percentages, and partial claims, not the price of a repair. How surgical invoices are itemized and paid is in pet insurance and surgery coverage.
Which waiting period applies to a torn cruciate?
The orthopedic waiting period, which runs up to 6 months at some insurers rather than the 14 to 30 days a general illness wait uses. This is the clause that decides most first-year cruciate denials, and it is set at the state filing level, so it prints on your own documents.
We publish the two day counts we have confirmed and no others. Lemonade applies a 6-month wait to cruciate ligament events, as set out in our Lemonade pet insurance review. Embrace's orthopedic wait can run 6 months with a waiver exam path that shortens it, per our Embrace pet insurance review. Every other insurer's orthopedic day count is queued for our document check: orthopedic waiting periods pending verification for this policy year. The way three separate clocks run at once on a single policy is explained in pet insurance waiting periods.
Ask about the waiver exam by name where an insurer offers one. A veterinarian examines the knees and certifies them sound, and the long orthopedic wait shortens in exchange, which is the only lever an owner controls on this clause.
What happens to the second knee?
At insurers that apply a bilateral clause, a cruciate tear documented before enrollment excludes the other knee as well. The clause treats paired structures as one condition, and cruciate ligaments are the case it was written for.
This produces the most expensive misunderstanding in pet insurance. An owner pays for one repair, buys a policy afterward to protect against the next one, and discovers that the next one is the single claim the policy has already ruled out. Our Lemonade review states that bilateral conditions follow the industry pattern there, with a cruciate tear before enrollment excluding the other knee. Where a review on this site has not confirmed the wording, we leave it unstated rather than assume the market default applies. The clause and how to find it in a policy document are set out in bilateral condition exclusions.
When does a limp become a pre-existing condition?
The moment it is written in the chart before coverage starts or during a waiting period, even if nobody named a ligament. A note reading intermittent hind limb lameness in March counts against a cruciate claim in September, because policies define a condition by when signs first appeared rather than by when a diagnosis was made.
Cruciate disease is degenerative in most dogs rather than a single traumatic event, so the early signs are mild and easy to record casually. Sitting with one leg out to the side, stiffness after rest, and a limp that resolves in a few days all appear in charts long before a rupture. None of them is curable in the sense that restores coverage, so the exclusion holds. The full definition is in pet insurance and pre-existing conditions.
Which dogs tear cruciate ligaments?
Labrador Retrievers, Rottweilers, Newfoundlands, Staffordshire Bull Terriers, and Boxers appear most often, with overweight dogs of any breed close behind. Body mass and knee conformation are the shared factors, which is why the condition is not confined to one breed group.
Small dogs and cats tear cruciate ligaments too, more often through a genuine accident than through slow degeneration. Breed is a pricing input rather than a coverage decision: an insurer prices a Rottweiler higher for what it expects to pay, then applies the same symptom-timing test it applies to every other dog. Breed-level cost detail sits in our Rottweiler insurance cost guide.
What should you do if your dog has already torn one?
Four moves, in order of how much they help.
- Insure anyway, for everything else. The recorded knee stays excluded, and every unrelated accident and illness is covered normally, which for a young dog is still usually worth buying.
- Find the bilateral wording before you pay. Search the definitions and exclusions sections for the word bilateral. One minute per policy settles whether the second knee is buyable at all.
- Get the record and read the dates. The earliest lameness note, not your memory of when the limp started, is the date the insurer will use.
- If a claim is denied, ask for the reason in writing. A denial that treats an unrelated injury in the same leg as the same condition is worth challenging with a note from your veterinarian. The appeal sequence is in why pet insurance claims are denied.
