Dog ACL Surgery Cost: What You'll Pay & Why

Cost guide · By Argos Paws research team · Published November 12, 2026 · Updated November 12, 2026

Written for general planning, not medical advice — no one at Argos Paws is a veterinarian. If something is wrong with your dog right now, call your vet or the nearest emergency clinic.

ACL surgery for a dog typically runs $1,500–$7,000+Prices checked Nov 12, 2026, according to PetMD — and that figure is per knee. It's one of the most expensive common surgeries a dog owner faces, and it often comes twice: roughly half of dogs that tear one knee's ligament tear the other within one to two years, so a single injury frequently means budgeting for two operations. The biggest drivers are your dog's size, whether a general practice vet or a specialist orthopedic surgeon does the work, and where you live.

What ACL/CCL surgery actually is

The cranial cruciate ligament (CCL — called the ACL in people) stabilizes the knee joint. When it tears, partially or fully, the knee becomes unstable: the shin bone slides forward with each step, the joint inflames, and the dog limps, sometimes suddenly after a jump or a slip, sometimes gradually as a weakened ligament frays over time. Cruciate tears are especially common in large, active dogs, and in some breeds the ligament degenerates with age or weight, so the tear can happen during entirely ordinary activity.

Surgery restores stability to the joint. Several surgical techniques exist — including TPLO (tibial plateau leveling osteotomy) and lateral suture repair — and the choice between them is the surgeon's, based on your dog's size, activity level, and the condition of the joint. This page doesn't price techniques against each other, because the technique is only one part of the bill and the right choice depends on the individual dog, not the price tag. PetMD reports an 85-90% success rate for CCL surgery overall.

5 factors that actually move the price

• Your dog's size. The dominant factor. A larger dog needs more anesthesia, a longer procedure, larger implants where they're used, and more post-operative medication — which is why the estimator's base range rises with size across PetMD's overall $1,500-7,000+ span.
• Who performs it. A general practice vet, a specialist orthopedic surgeon, and an emergency hospital each price the same operation differently. The specialist premium buys focused training and high volume; the emergency premium buys an operation done now, after hours, rather than scheduled.
• Your location. The same surgery costs meaningfully more in a high-cost city than in a lower-cost area, the same regional spread that shows up across all veterinary pricing.
• What's included in the quote. Pre-surgical bloodwork, the X-rays used to confirm the tear, anesthesia, pain medication, follow-up visits, and rehabilitation are sometimes bundled and sometimes billed separately. Two quotes can differ by hundreds of dollars purely on what's inside them — always ask for the itemized list.
• The other knee. Roughly half of dogs that tear one cruciate ligament tear the other within one to two years, according to PetMD. The second surgery costs about the same as the first, so the true lifetime cost of a cruciate injury is often double the single-surgery figure — worth budgeting for from the start.

Worked examples

These three scenarios use the exact same math as the estimator above — they're illustrative, not real invoices, but they show how the pieces combine. Each one assumes a medium dog at U.S.-average pricing unless stated otherwise, and every figure is for one knee; try the same settings in the estimator to reproduce the figure:

• Daisy, a small dog having CCL surgery at her regular general practice vet: $1,500 – $4,000.
• Bruno, a large dog referred to a specialist orthopedic surgeon: $2,750 – $7,750 — the large-dog base range plus the specialist premium, running past PetMD's $7,000 headline figure, which is why PetMD states the range as "$7,000 or more."
• Milo, a medium dog needing emergency surgery after a sudden tear, in a higher-cost area:$2,750 – $7,000 — the emergency premium and the higher-cost area stack on top of the medium-dog base range.

Will pet insurance cover it?

Usually, yes — cruciate ligament repair is standard under accident-and-illness coverage, not a separate add-on you have to opt into. The catch is the same one that applies to every pet insurance claim, and it bites hardest here: it only helps if the condition wasn't already showing symptoms before your policy started, since pre-existing conditions are excluded — and a limp or a knee diagnosis already on your dog's record before enrollment won't be covered. A single CCL surgery can run $1,500-$7,000+, and large breeds face meaningfully higher odds of needing one, which is exactly why enrolling as a puppy, before any joint issue is on record, is the move that actually protects you.

Frequently asked questions

How much does ACL surgery cost for a dog?

PetMD puts the overall range at $1,500 to $7,000 or more, with the exact figure depending mainly on your dog’s size, whether a general practice vet or a specialist orthopedic surgeon performs it, and where you live. Our own emergency estimator puts ACL repair at $2,000-7,000 in an emergency setting, and our emergency and insurance guides use $1,000-6,000 per knee — all three ranges overlap, and which one applies depends on the setting. The figure is per knee: a dog that eventually needs both knees done pays it twice.

What is the difference between ACL and CCL in dogs?

None in practice — they are two names for the same ligament. In people it is called the anterior cruciate ligament (ACL); in dogs the correct anatomical name is the cranial cruciate ligament (CCL), because dogs stand on four legs and their anatomy is described front-to-back rather than top-to-bottom. Vets and owners use both terms, so this page does too. A torn CCL makes the knee unstable, which is why the dog limps and why surgery is usually recommended.

Is the cost per knee?

Yes. Every figure on this page — PetMD’s $1,500-7,000+, the $1,000-6,000 per-knee range in our emergency and insurance guides — is for one knee. That matters because roughly half of dogs that tear one knee’s ligament tear the other within one to two years, according to PetMD, so a single injury often means budgeting for two surgeries over time rather than one.

Will my dog tear the other knee too?

Quite possibly. PetMD reports that roughly half of dogs that tear one cranial cruciate ligament will tear the other within one to two years. The underlying causes — body shape, weight, activity, and in some breeds a predisposition to ligament degeneration — usually affect both knees, not just the one that gave way first. That is part of why a single injury often means budgeting for two, and why weight management after the first surgery matters.

Does pet insurance cover ACL surgery?

Usually yes, if the policy is active and the tear was not already showing symptoms before you enrolled — cruciate ligament repair is standard under accident-and-illness coverage, not a separate add-on. The catch is the pre-existing-condition exclusion: a limp or a knee diagnosis already on your dog’s record before enrollment will not be covered, and some policies also apply a waiting period specifically for cruciate ligament claims. Enrolling as a puppy, before any joint issue is on record, is what actually protects you here. Our pet insurance calculator can give you a sense of what coverage costs before you need it.

Why does a specialist orthopedic surgeon cost more?

You are paying for focused training, specialized equipment, and volume: a board-certified orthopedic surgeon performs knee surgeries constantly, which is also why outcomes are generally strong — PetMD reports an 85-90% success rate for CCL surgery. A general practice vet can perform some cruciate repairs, and that is often the cheaper route, but complex cases, very large dogs, and repeat surgeries are usually referred to a specialist. The estimator above shows the premium as a separate line so you can see what the referral adds.

How long is recovery after ACL surgery?

Recovery is measured in weeks of restricted activity, not days — your dog will need confinement, leashed walks only, and a gradual return to normal exercise on a schedule your surgeon sets. PetMD reports an 85-90% success rate for the surgery itself, but that figure assumes the recovery plan is actually followed: a dog that runs or jumps too early can undo the repair. Expect follow-up visits to check healing, and ask your surgeon upfront what rehabilitation or physiotherapy they recommend, since that is part of the total cost and the total time commitment.

What should I ask before booking the surgery?

Ask what the quote actually includes: pre-surgical bloodwork, the X-rays or other imaging used to confirm the tear, anesthesia, the surgery itself, pain medication, follow-up visits, and any recommended rehabilitation. Ask which surgical technique they recommend for your dog’s size and activity level and why — several techniques exist, and the choice is the surgeon’s, based on your dog. And ask for the plan if the other knee goes later: knowing the cost and timing upfront is better than discovering it mid-recovery.
