Dog ACL surgery (technically called CCL surgery in veterinary medicine) typically costs between $1,500 and $7,000 or more, depending on the procedure, your dog’s size, and where you live. That’s a wide range because there are three main surgical options at very different price points, and the total bill includes more than just the operation itself.
Cost by Surgery Type
The three most common procedures for a torn cruciate ligament in dogs carry distinctly different price tags, largely because they require different levels of surgical expertise and equipment.
Lateral suture repair (extracapsular repair): $1,500 to $3,000. This is the least expensive option. A surgeon places a strong suture outside the joint to stabilize the knee. It works best for smaller, less active dogs. Dogs over about 40 pounds or those with complete tears generally do better with one of the other two procedures.
TTA (tibial tuberosity advancement): Slightly less than or comparable to TPLO pricing. This procedure changes the angle of the knee joint by repositioning the front of the shinbone. It requires specialized implants and a surgeon experienced with the technique, which keeps costs in the moderate-to-high range.
TPLO (tibial plateau leveling osteotomy): Around $3,500 for one knee, or about $6,000 if both knees are done in the same surgery. TPLO is the most commonly recommended option for medium and large breed dogs. It involves cutting and rotating the top of the shinbone so the knee stays stable without a functioning ligament. The higher cost reflects the advanced equipment, specialized implants, and the fact that a board-certified surgeon typically performs it.
What’s Included in the Surgery Price
Some veterinary practices bundle everything into a flat rate, while others bill each component separately. This makes comparing quotes tricky if you’re not looking at the same line items. A comprehensive surgical package generally includes pre-operative bloodwork, anesthesia and monitoring, the surgical procedure itself, implants and materials, pre- and post-operative X-rays, hospitalization, pain management, and a discharge plan for recovery at home.
If your quote doesn’t include some of these items, expect additional charges. Pre-op bloodwork, for example, ensures your dog is healthy enough for anesthesia. Sedated X-rays are necessary for surgical planning, especially for TPLO and TTA, where precise bone measurements determine implant sizing. When these are billed separately, they can add several hundred dollars to the total.
Why Prices Vary So Much
Geography is one of the biggest factors. Surgery at a specialty hospital in a major metro area can cost twice what a rural veterinary surgeon charges for the same procedure. Board-certified veterinary surgeons also charge more than general practitioners, though for bone-cutting procedures like TPLO, most veterinarians recommend a specialist.
Your dog’s size matters too. Larger dogs need bigger implants, more anesthesia, and longer surgical times. A 100-pound Labrador will cost more to operate on than a 25-pound Cocker Spaniel, even for the same procedure at the same clinic. Whether the tear is partial or complete, and whether the meniscus (a cartilage pad inside the knee) is also damaged, can affect the complexity and cost of surgery as well.
Costs Beyond the Operating Room
The surgery bill is the largest single expense, but recovery adds to the total. Most dogs need pain medication and anti-inflammatory drugs for several weeks, plus antibiotics to prevent infection. You may also need a recovery cone or surgical suit, a supportive sling for the first days of walking, and possibly a crate or pen to restrict movement during the 8 to 12 week healing period.
Physical rehabilitation can speed recovery and improve outcomes, especially for active dogs or those with significant muscle loss. Canine rehab sessions, which may include underwater treadmill work, therapeutic exercises, and laser therapy, vary widely in price depending on your area and the facility. Some dogs do well with a home exercise program provided by the surgeon, while others benefit from professional rehab over several weeks.
There’s also a meaningful risk that the other knee will eventually need surgery. Studies have found that a large percentage of dogs who tear one cruciate ligament go on to tear the other, sometimes within a year or two. This is worth factoring into your long-term financial planning.
Pet Insurance and Financing
Pet insurance can cover cruciate ligament surgery, but only if you have a policy in place before any symptoms appear. Cruciate tears are one of the most common and expensive claims insurers deal with, so the rules around them tend to be strict. Many policies have a specific waiting period for cruciate ligament problems, often around six months from when coverage starts. If your dog shows any lameness or knee issues before that waiting period ends, the condition will likely be classified as pre-existing and excluded from coverage.
This gets especially complicated with bilateral tears. If your dog injures one knee before you have insurance, some insurers will also exclude the opposite knee, considering it a related condition. Others will cover the second knee if symptoms didn’t appear until after the waiting period. The details vary by provider, so reading the fine print matters.
If insurance isn’t an option, many veterinary practices offer payment plans or work with third-party financing companies that let you spread the cost over months. Some also offer a discount for paying the full amount upfront. It’s worth asking about both before committing to a surgical plan, since the same procedure at two different clinics in the same city can differ by $1,000 or more.
Is Surgery Worth the Cost?
For dogs over 40 pounds, highly active dogs, or those with a complete ligament rupture, surgery offers the best chance at full recovery. Without it, the knee remains unstable, arthritis progresses faster, and the dog compensates by shifting weight to the other legs, which increases the risk of injuring the opposite knee.
Smaller, less active dogs sometimes manage with conservative treatment: strict rest, anti-inflammatory medication, weight management, and a knee brace. This approach costs far less upfront, but it doesn’t restore normal joint mechanics. Scar tissue forms to provide some stability, though the joint remains prone to arthritis and further injury. For many owners, the decision comes down to the dog’s size, activity level, age, and what they can realistically afford.
When comparing surgical quotes, ask each clinic exactly what’s included in their price. A $2,500 quote that doesn’t cover anesthesia monitoring, post-op X-rays, or hospitalization may end up costing as much as a $3,500 flat-rate package that bundles everything together.
