Cruciate ligament rupture is the single most common orthopedic injury in dogs and one of the biggest reasons people regret not having insurance. Here's a plain-English look at the procedure, the severity, and what insurance covers.
What it costs in Canada
| Scenario | Typical cost (CAD) |
|---|---|
| Initial vet exam + diagnosis | Low cost — a routine visit |
| Sedated X-rays to confirm the tear | Moderate — adds significantly to the diagnosis bill |
| TPLO surgery (most common for medium and large dogs) | High four-figure range — the largest single line item |
| TTA surgery (alternative technique) | Comparable to TPLO, sometimes slightly lower |
| Lateral suture (small dogs under ~15 kg only) | Notably cheaper, but rarely appropriate for large breeds |
| Post-op rehabilitation (6–12 weeks) | Adds meaningfully to the total |
| Total typical out-of-pocket for a large dog | Frequently $5,000+, often more once rehab is included |
Costs vary significantly by city, clinic, surgeon, and your dog's size. Get a written estimate from your vet or surgeon — and a quote from an insurer — before assuming any specific number.

Considering insurance?
Cruciate injuries are exactly the scenario insurance is designed for — large, sudden, and roughly 40–60% likely to happen to the other leg too. If your dog is a large breed, get a quote before you need one. Quote tools are free and take a few minutes.
Frequently asked questions
Is ACL surgery covered by pet insurance in Canada?
Yes, by every major Canadian comprehensive policy — provided the injury occurred after your waiting period ended and was not a pre-existing condition. Most insurers also cover the unaffected leg if it ruptures later.
Do I have to do surgery?
For most medium and large dogs, surgery is the standard of care because the joint doesn't heal stably on its own. Conservative management is sometimes attempted for small dogs or dogs who can't undergo anaesthesia.
Will the other knee blow out?
Veterinary studies consistently report that a large share of dogs who rupture one cruciate will rupture the other within 12–24 months. Plan for it financially.
How quickly do I need to decide?
You usually have time to get a second opinion and an insurance quote. Most surgeons book procedures days or weeks out. Don't be pressured into same-day decisions.
