Does Pet Insurance Cover ACL (Cruciate) Surgery in Dogs?
A torn cruciate ligament (the dog equivalent of a human ACL) is one of the most common — and most expensive — orthopedic injuries in dogs. If you’re wondering whether insurance will cover the surgery, the answer is yes, with important conditions. This guide explains ACL/cruciate cover in 2026.
What’s in this guide
What an ACL (cruciate) tear is
The cranial cruciate ligament stabilises a dog’s knee. When it tears — often from a sudden twist or gradual degeneration — the dog becomes lame and usually needs surgery (commonly a TPLO or TTA) to restore the joint. It’s especially common in active and larger breeds like Labradors, Rottweilers and Shepherds.
What ACL surgery costs without insurance
| Item | Typical cost |
|---|---|
| TPLO / TTA surgery (one knee) | $3,000–$5,000 |
| Diagnostics (X-ray, exam) | $300–$800 |
| Rehab / physiotherapy | $500–$2,000 |
| Both knees (common over time) | $6,000–$10,000 total |
When insurance covers it
A comprehensive accident-and-illness plan covers cruciate surgery, diagnostics and rehab — reimbursed at your rate (70–90%) after the deductible — as long as two things are true: the knee showed no prior symptoms before the policy started, and the orthopedic waiting period has passed. Insure before any limp is recorded and you’re covered.
The orthopedic waiting period
This is the catch with cruciate cover. Many insurers apply a special 6-month waiting period for orthopedic conditions. Some shorten or waive it after a clean vet exam. If you have a breed prone to cruciate tears, choosing an insurer with a short or waivable orthopedic wait is essential. More on waiting periods here.
The second-knee problem
Dogs that tear one cruciate frequently tear the other later. Watch how your insurer handles this: some treat the second knee as a separate covered event; others may consider it related to the first and exclude it. Always confirm bilateral cruciate cover before you buy, especially for high-risk breeds.
Frequently asked questions
Does pet insurance cover ACL/cruciate surgery?
Yes — comprehensive plans cover cruciate surgery (typically $3,000–$5,000 per knee), provided the knee had no prior symptoms and the orthopedic waiting period has passed.
How much does dog ACL surgery cost?
Usually $3,000–$5,000 per knee including diagnostics, with rehab on top. Both knees over time can total $6,000–$10,000.
Why might cruciate surgery not be covered?
If the knee showed symptoms before the policy (pre-existing) or the claim falls within the orthopedic waiting period (often 6 months).
Is the second knee covered if the first tears?
It depends on the insurer — some cover it as a new event, others may exclude it as related. Confirm bilateral cruciate cover before buying.
How do I make sure ACL surgery is covered?
Insure before any limp or knee issue is recorded, choose a plan with a short or waivable orthopedic wait, and confirm bilateral cover.
