TPLO and ACL surgery cost for dogs
By Raúl Vaquerizo · Published · Editorial policy
Surgery and follow-up care for a torn cranial cruciate ligament, the dog equivalent of a human ACL tear, typically costs $5,459 to $12,738 in the US according to MoneyGeek’s published range. TPLO (tibial plateau leveling osteotomy) is one of the common surgical repairs. Pet insurance can pay most of it, but only if the knee problem was not in your dog’s record before the policy started, and a $5,000 annual limit will not cover a bill at the top of that range.
What the cost includes
The published range covers surgery and follow-up care. Depending on the clinic, the bill can include the exam and imaging, the surgery with anesthesia and hospital stay, medication, rechecks and rehabilitation. Prices also vary with where you live, the surgeon, the size of the dog and any complications, which is why the range is wide. Ask for an itemized estimate before surgery.
Which dogs are most at risk
Two large US studies point to the same groups:
- Breed. A study of young dogs at US veterinary teaching hospitals found a breed predisposition to cruciate rupture in the Neapolitan Mastiff, Akita, Saint Bernard, Rottweiler, Mastiff, Newfoundland, Chesapeake Bay Retriever, Labrador Retriever and American Staffordshire Terrier (Duval et al., 1999).
- Size and age. In 1,243,681 dogs from the US Veterinary Medical Database, large and giant breeds were more likely to have cruciate ligament deficiency, and dogs older than 4 were at higher risk (odds ratio 1.82 for dogs over 4 to 7 years) (Witsberger et al., 2008).
- Neutering. The same study found higher odds in castrated males (odds ratio 1.68) and spayed females (2.35) than in other dogs.
- Trend. Prevalence of cruciate problems increased significantly over the four decades the study covered.
If you have one of these breeds, see its page for price and other risks: Labrador Retriever, Rottweiler, Newfoundland, Saint Bernard.
What pet insurance would pay
Assume a $9,000 bill, near the middle of the range, on an accident and illness policy:
| Policy | Insurer pays | You pay |
|---|---|---|
| $500 deductible, 80%, $5,000 limit | $5,000 | $4,000 |
| $500 deductible, 80%, $10,000 limit | $6,800 | $2,200 |
| $250 deductible, 90%, unlimited | $7,875 | $1,125 |
| $1,000 deductible, 70%, unlimited | $5,600 | $3,400 |
The arithmetic is (bill − deductible) × reimbursement rate, capped at the annual limit. Try your own numbers in the payout calculator.
Coverage details that matter for knee surgery
- Orthopedic waiting periods. The NAIC Pet Insurance Model Act lists ruptured cranial cruciate ligaments as an orthopedic condition. In states that adopted it, waiting periods for illnesses and orthopedic conditions not caused by an accident cannot exceed 30 days, and insurers must let you waive them after a vet exam. Elsewhere, each insurer sets its own orthopedic waiting period, so compare them before you buy.
- Accident-only plans. NAPHIA lists ligament tears among the benefits of accident-only plans. If a tear is treated as an accident under your policy, an accident-only plan may pay, but read the definition of “accident” and any orthopedic exclusions carefully.
- Pre-existing conditions. Limping, a vet note about knee pain or a diagnosed partial tear before coverage starts can make the knee a pre-existing condition. Insure before any of that is recorded.
- The other knee. Ask the insurer, before you buy, how it would treat a later problem in the other knee.
Is it worth insuring a dog for this risk?
For a high-risk breed, one cruciate repair can equal many years of premiums. A 3-year-old Labrador costs about $505 a year to insure in our estimate, so a $9,000 surgery is worth roughly 18 years of premiums, and Labradors also have higher odds of osteoarthritis than other dogs in UK primary care. If you could not pay a bill of that size from savings, insurance with an annual limit of $10,000 or more is the safer choice. For a broader view, see is pet insurance worth it?
