WHAT'S COVERED
A torn ACL is the most common orthopedic surgery in dogs, and one of the most expensive bills a healthy dog will ever hand you. In dogs the ligament is called the cranial cruciate ligament (CCL) — the equivalent of the human ACL — and unlike a human athlete's sudden tear, a dog's CCL usually degenerates and frays over time until it finally gives out. The result is a wobbly, painful knee and, without treatment, worsening arthritis.
The headline number most owners quote is $3,500–$6,500 per knee for a TPLO, the gold-standard repair for medium and large dogs. But the real total swings a lot based on which surgery your dog needs, your dog's size, and where you live. Here's the breakdown.
Cost by surgical technique
There isn't one ACL surgery — there are three common ones, and price tracks closely with the technique your surgeon recommends for your dog's size and activity level.
| Procedure | Typical cost (per knee) | Usually recommended for |
|---|---|---|
| Extracapsular (lateral suture) A synthetic suture replaces the ligament | $1,000–$2,500 | Small / light, less active dogs |
| TTA (tibial tuberosity advancement) Reshapes the bone to neutralize the knee | $3,000–$5,500 | Medium to large dogs |
| TPLO (tibial plateau leveling osteotomy) Cuts and rotates the tibia; plate + screws | $3,500–$6,500 | Medium, large, active or athletic dogs |
Ranges reflect typical U.S. pricing and vary widely by region, clinic type, and dog. Board-certified surgeons at specialty centers sit at the top of each range; general-practice vets and teaching hospitals often sit lower.
What's actually in the bill
The quoted surgery price usually bundles most of the visit, which is why "just the surgery" comparisons mislead. A typical estimate folds in:
- Exam & diagnosis — orthopedic exam and sedated X-rays to confirm the tear and plan the cut.
- Pre-op bloodwork and IV catheter to clear your dog for anesthesia.
- General anesthesia & monitoring for the length of the procedure.
- The surgery itself, plus any implants (a TPLO uses a titanium or stainless plate and screws).
- Hospitalization and same-day recovery care.
- Take-home meds — pain control and often antibiotics — plus an e-collar.
- Rechecks and suture removal, and usually a follow-up X-ray to confirm the bone has healed.
What makes the price swing
Two dogs with the same tear can get estimates thousands of dollars apart. The biggest drivers:
- Dog size. Bigger dogs need bigger implants and are usually steered toward TPLO, the priciest option.
- Where you live. Major metros and coastal cities run well above rural and Midwest pricing for the identical procedure.
- GP vet vs. board-certified surgeon. A specialty referral center costs more than a general-practice vet who does the surgery in-house — though many owners choose the specialist for a complex or large-dog case.
- Complications. Infection, implant issues, or a delayed union add recheck visits, meds, and sometimes a second procedure.
- One knee or two. See below — this is the sleeper cost.
The non-surgical option (and its cost)
Surgery isn't the only path, especially for small or older, less active dogs. Conservative management means strict activity restriction, weight loss, anti-inflammatory medication, often a custom knee brace, and physical rehab. It can work — but it trades a big one-time bill for a smaller ongoing one: months of meds, rehab, and long-term arthritis care. For a big, active dog, most surgeons still consider surgery the better long-term value because it stabilizes the joint sooner.

Does pet insurance cover it?
This surgery is close to the perfect argument for pet insurance — a large, unpredictable bill on an otherwise healthy dog. Most accident-and-illness policies reimburse cruciate surgery, but only if you enrolled before any sign of a knee problem, and many insurers tack on a dedicated orthopedic or cruciate waiting period (often six months). Once one knee is diagnosed, the second is typically excluded as pre-existing. The lesson is the same as everywhere on this site: the value of insurance is in enrolling young and healthy. We run the full break-even math in our is-pet-insurance-worth-it guide.
Ways to lower the cost
- Get two or three written estimates. Prices for the same surgery vary more than almost any other line item in vet care.
- Ask a veterinary teaching hospital. University clinics often price below private specialty centers.
- Ask whether your GP vet does the surgery in-house. For the right dog and technique, this can be markedly cheaper than a referral center.
- Look at financing like CareCredit or in-clinic plans to spread the bill — just watch the interest terms.
- Don't skip rehab and the rest period. Cutting corners on recovery is how a single surgery becomes a revision surgery.
