Dog ACL Surgery Cost in 2026: $1,000 to $10,000

A dog ACL (cranial cruciate ligament) surgery costs $1,000 to $10,000 in the United States, and $3,525 is the typical price. Regionally the typical price runs from $3,125 in the Midwest to $4,700 in California — a 1.5x spread for the same procedure.

Your dog does not have an ACL, and that changes the price

The ligament is the cranial cruciate (CCL or CrCL); ACL is the human name for the same structure. The distinction is financial, not pedantic. The American College of Veterinary Surgeons describes canine rupture as slow degeneration of the ligament rather than a sudden injury to a healthy one, with sudden trauma being very rare.

A degenerating ligament is a disease of the dog, not an accident to one leg. That is why partial tears in dogs "almost always progress to a full tear over time" and why the same process is usually running in the opposite knee.

It also explains why a graft repair — the standard human operation — is not on the menu. ACVS notes the canine CrCL is not usually replaced with a graft because bipedal and quadrupedal knees load differently, so every surgical option below stabilises the joint around the missing ligament instead of rebuilding it.

The four treatment paths, priced against each other

Four paths exist and they do not cost the same. Published national figures from MetLife put extracapsular repair at $1,000 to $3,500 and an osteotomy at $2,500 to $7,500 for the same torn ligament. The decision is driven by the dog's size, age and activity level, not by the severity of the tear.

• Non-surgical management. Pain medication, strict activity restriction, rehabilitation, sometimes a custom brace. ACVS warns that knee pain persists because the instability persists, and that a knee stabilised by scar tissue is predisposed to reinjury.
• Extracapsular (lateral) suture, $1,000 to $3,500. Heavy suture placed outside the joint while scar tissue forms. ACVS calls it often less costly but says it may not be the best choice for larger and younger patients because of the arthritis that follows.
• TPLO, $2,500 to $7,500. The tibia is cut and rotated, then plated. The full cost breakdown is on our TPLO dog surgery cost page, including why the same operation varies by $3,300 between facilities.
• TTA, in the same band as TPLO. A linear cut advancing the front of the tibia, held with a wedge, plate and screws. Same class of procedure, same several weeks of confinement.

The one number worth holding on to: ACVS reports significant improvement in 85 to 90% of surgically repaired cases, and that arthritis progresses more slowly after surgery than after medical management.

What the workup costs before anyone quotes you surgery

Expect $300 to $900 before a surgical figure is even spoken. That covers the orthopaedic exam, radiographs and pre-anesthetic bloodwork, and it is billed whether or not you go ahead. Diagnosis is largely a palpation finding — the cranial drawer and tibial compression tests — with imaging used for staging and surgical planning.

The individual lines are in the invoice table below, but the shape is consistent: CareCredit puts dog radiographs at a $213 national average, a CBC at $104 and a chemistry panel at $164.

A specialist consultation sits on top of that. Mission Veterinary Emergency and Specialty publishes $200 for it, which is at the low end of what referral centres charge in high-cost metros.

The meniscus is priced after the knee is already open

The meniscus is the line item nobody can quote in advance. It is the cartilage pad between the femur and the tibia, and ACVS notes it can be damaged when the cruciate ruptures because the shin bone slides forward and crushes it. Whether it is torn is established with the joint open and the dog anesthetised.

If it is torn, the surgeon removes the damaged portion, which adds operating time to whichever stabilisation was planned. Some surgeons also perform a meniscal release on an intact meniscus at the time of stabilisation, to reduce the risk of a later tear — a prophylactic decision made to avoid a second anesthesia rather than to treat something visible.

Ask two questions at the estimate stage. Whether meniscal treatment is inside the quoted figure or billed on top of it, and whether the surgeon performs release prophylactically. Those answers move the total more than any negotiation over the headline number will.

A clicking or popping noise in the knee is the sign ACVS associates with a meniscal tear. If you have heard one, mention it before the estimate is written rather than after.

Why the second knee is the number that actually matters

Budget for two knees, not one. ACVS states that up to 50% of dogs diagnosed with cruciate disease in one knee develop it in the other, usually within 12 to 18 months, and puts the long-run figure at 40 to 60%. A peer-reviewed cohort of 380 dogs in PLoS ONE found 204 of them — 54% — ruptured the contralateral ligament, at a median of 947 days.

Run that against the $3,525 national typical price and the honest lifetime figure for a coin-flip case is roughly $7,050, spread over about two and a half years. No incumbent cost page states this, and it is the single most useful thing to know at the moment you are handed the first quote.

There is a second-order effect that is easy to miss. Once one knee is on the record, the second one is a known risk rather than an unknown one — which is exactly the distinction insurers price on, covered in the coverage section further down this page.

When is surgery not the right call?

Non-surgical management is a legitimate path for some dogs, and pretending otherwise would be dishonest. ACVS frames the first decision as surgical versus conservative, resolved by activity level, size, age, conformation and the degree of instability — not by a rule that every torn cruciate gets operated.

What conservative management does not do is remove the instability. ACVS is explicit that pain persists while the knee remains unstable, which is why strict leash-based activity restriction does more for comfort than medication does.

Custom bracing is the option most often oversold to owners at this point. ACVS notes bracing is relatively new in canine orthopaedics with little outcome data, that braces can be expensive, and that sores, continued pain and patient intolerance are real complications. Priced honestly, a brace is a spend with thin evidence behind it, not a cheap substitute for a repair.

The recovery bills that no quote includes

Add $400 to $1,500 after the surgical invoice closes. Recheck radiographs run $100 to $350, take-home analgesia $29 to $200, and MetLife reports $1,000 or more for a full course of post-operative rehabilitation, which is commonly recommended after an osteotomy and almost never bundled into the surgical quote.

Confinement is the hidden line nobody itemises. ACVS describes several weeks of restricted activity as critical to avoid implant and healing complications, which for many households means paid daycare, a crate, ramps, or time off work.

Rehabilitation is also the line most worth paying for rather than trimming. It is the part of the spend that is optional on the invoice and load-bearing for the outcome.

How much does dog knee surgery cost at a general practice versus a specialist?

A university teaching hospital quotes $3,300 to $4,200 for the osteotomy while private referral practices quote $3,500 to $7,500 for the same operation, per Virginia Tech's published estimate and MetLife's national band. Lateral suture repair is the path most often available in general practice, which is part of why it sits $1,500 to $4,000 lower.

The trade at a teaching hospital is scheduling, not skill: longer waits, less flexibility, residents and faculty on the case. For a non-emergency orthopaedic procedure that is usually an acceptable trade.

Two more knee conditions travel with this one. Dogs with a luxating patella are predisposed to cruciate disease, and hind-limb lameness that turns out to be hip dysplasia is priced very differently. The rest of our pricing work is indexed on the vet cost index.

Dog ACL (Cranial Cruciate Ligament) Surgery cost by region

These are the prices behind the range at the top of the page, one row per geography we could source. The basis column says how each row was arrived at.

What changes the price

Two invoices for the same procedure diverge for a small number of reasons. These are the ones that move the total most.

Surgical technique chosen

Lateral suture runs $1,000-$3,500 and a TPLO or TTA $2,500-$7,500 - a 2-3x difference for the same torn ligament, decided mainly by the dog's size and activity level

The second knee ruptures too

Effectively doubles the lifetime cost. ACVS reports up to 50% of dogs diagnosed in one knee develop the same problem in the other, usually within 12-18 months, and a peer-reviewed cohort of 380 dogs found 54% ruptured the opposite side

Board-certified surgeon at a referral hospital versus a general practice

Osteotomy techniques are concentrated at referral centres; a university teaching hospital quotes $3,300-$4,200 while private referral practices quote $3,500-$7,500 for the same operation

Concurrent meniscal tear found at surgery

Adds operating time for meniscectomy or meniscal release, which surgeons often perform prophylactically to avoid a second operation

Pre-operative workup

+$300-$900 for the exam, radiographs and bloodwork before the surgical line item is reached

Post-operative rehabilitation

+$1,000 or more across a course of sessions - commonly recommended after osteotomy and rarely included in the surgical quote

What the itemized invoice looks like

Clinics quote a bundled number and itemize afterwards. This is the decomposition, so you can read a real estimate line by line before you sign it.

Does pet insurance cover dog ACL (cranial cruciate ligament) surgery?

Dog ACL (Cranial Cruciate Ligament) Surgery is normally covered by a standard accident-and-illness policy. Cruciate surgery is one of the most frequently claimed conditions on accident-and-illness policies and is normally covered once any waiting period has passed. Two traps matter more here than on any other procedure. First, if one knee was already diagnosed before enrolment, MetLife confirms a claim on the second knee is typically excluded as pre-existing - and the contralateral rupture rate is 40-60%. Second, several carriers apply a longer waiting period specifically to cruciate conditions; that practice is widely described but we could not verify the exact length against any carrier's own published policy document, so check the wording before relying on it.

What you would get back: 70-90% of the covered bill after the annual deductible, on a policy bought before any lameness was recorded in either knee.

Coverage rules differ enough between carriers that the only useful answer is a side-by-side: our pet insurance comparison for dog ACL (cranial cruciate ligament) surgery shows which policies pay for it, what the waiting period is, and what counts as pre-existing.
