If your dog just tore their ACL, technically the cranial cruciate ligament (CCL) in dogs, you are probably looking at a vet estimate somewhere around $3,500 to $7,500 per knee and wondering whether your pet insurance will actually cover it.
The reassuring part is that most accident and illness plans do cover cruciate repair. What pet parents need to consider are two policy details: the waiting period and the bilateral exclusion. Both vary a lot from one insurer to the next. This guide walks through what is covered, what isn’t, how each major insurer treats cruciate specifically, and how to set yourself up for the cleanest possible claim, including the case where your dog has already torn one knee.
The short version
TPLO surgery typically runs $3,500 to $7,500 per knee. Most accident and illness plans cover CCL/ACL repair when the injury isn’t pre-existing. Two things to consider: the orthopedic waiting period (as short as 14 days at Pumpkin, with MetLife folding cruciate into its standard 14-day illness wait, and as long as 12 months at Nationwide) and the bilateral exclusion (if one knee was already injured before you enrolled, most insurers exclude the other side too). Roughly 30 to 50% of dogs that tear one cruciate go on to tear the second within a year or two, which is exactly why the bilateral rule matters so much.

What an ACL injury actually is
Dogs don’t technically have an ACL. They have a cranial cruciate ligament (CCL), which does the same stabilizing job the ACL does in a human knee. It keeps the tibia (shin bone) from sliding forward against the femur (thigh bone). When it tears, the knee becomes unstable and painful, and arthritis sets in without treatment. The University of Florida small animal hospital notes that people use “CCL” and “ACL” interchangeably in dogs, even though CCL is the technically correct term. Your vet will probably say both.
The bigger surprise is how dogs tear it. A human ACL usually goes in one dramatic athletic moment. Most canine CCL tears are degenerative rather than traumatic. The ligament weakens gradually over months or years, then ruptures during something ordinary, like jumping off the couch, turning sharply on a walk, or slipping on a wet floor.
This matters for insurance because a dog can show subtle early signs, such as occasional limping, stiffness after rest, or reluctance to jump, for months before the actual rupture. If any of those signs are in the vet record before you enroll, an insurer may treat the cruciate injury as pre-existing if veterinary records list those symptoms as related. That is the single most important reason to enroll early, well before any symptoms begin.
Which dogs are most at risk
CCL disease is the most common orthopedic injury in dogs. Risk is concentrated in a few groups:
- Larger and heavier breeds, including Labrador Retrievers, Golden Retrievers, Rottweilers, Newfoundlands, Mastiffs, Boxers, and Saint Bernards.
- Overweight dogs of any breed, because extra weight loads the joint and speeds up ligament wear.
- Spayed females and neutered dogs, which several studies link to higher CCL risk, though the mechanism isn’t fully understood.
- Dogs aged 6 to 10, the peak diagnosis window for medium and large breeds, though an acute traumatic tear can happen at any age.
- Newfoundlands specifically, which carry a documented genetic component. University of Wisconsin researchers developed a genetic test for the disease.
The 30 to 50% problem. Once a dog tears one CCL, the rate of tearing the other side runs 30 to 50% within one to two years per the University of Florida, and some sources put it higher. The cause is partly mechanical, because the dog shifts weight onto the good leg, and partly underlying, because if one ligament was degenerating, the other one probably is too. This is why the bilateral exclusion comes up so often on cruciate claims. It affects roughly half of all cases.
What CCL surgery actually costs
Three surgical procedures dominate, and cost tracks roughly with dog size:
| Procedure | Typical use | Cost per knee |
|---|---|---|
| TPLO (Tibial Plateau Leveling Osteotomy) | Standard for medium-to-large dogs (30+ lbs) | $3,500–$7,500 |
| TTA (Tibial Tuberosity Advancement) | Alternative to TPLO, often for medium dogs | $3,000–$5,500 |
| Lateral suture (extracapsular repair) | Dogs under ~30 lbs, less invasive | $1,200–$2,800 |
The procedure itself is rarely the whole bill. Add pre-op imaging ($300 to $600), anesthesia ($300 to $500), implant hardware on a TPLO ($700 to $800), post-op X-rays ($200 to $400), medications ($100 to $250), and eight to twelve weeks of recommended rehab ($1,000 to $2,500). All-in, a single TPLO commonly lands at $5,000 to $9,000. Specialty hospitals in major metros sit at the higher end. Teaching hospitals and rural specialty practices tend to charge less. The University of Wisconsin School of Veterinary Medicine cites $4,000 to $7,000 per knee for TPLO.
If both knees go, which is common, expect to multiply by roughly 1.7 to 2 times. Some surgeons offer a discount when both are done under one anesthetic event, but most cases stage the two surgeries six to twelve months apart for recovery reasons.
How insurance actually handles CCL
Three plan types exist, and they treat cruciate very differently:
| Plan type | CCL surgery covered? | Notes |
|---|---|---|
| Accident & illness | Yes, degenerative or acute | The standard plan type, and what most owners actually need for cruciate. |
| Accident-only | Sometimes, acute traumatic tears only | Most CCL tears are degenerative, so accident-only often won’t apply. |
| Wellness-only | No | Wellness plans cover routine care, never surgery. |
The accident-only line is subtle. If your dog jumps off the couch and ruptures the CCL on landing, that could look like an accident, but most insurers will treat it as illness because the ligament was already weakened due to the chronic underlying illness. If you rely on accident-only coverage for cruciate, plan on a harder claim. An accident and illness plan is the dependable choice here.
Why the waiting period matters so much for cruciate
Every plan has a waiting period, which is the stretch right after you enroll before your coverage becomes active. Conditions that occur during a related waiting period are considered pre-existing. For cruciate, three time horizons come into play:
- Standard illness waiting period, usually 14 days, which applies to most conditions.
- Orthopedic or cruciate waiting period, a separate, longer wait at some insurers, often six months.
- Vet-exam waiver, offered by a few insurers, where a clean orthopedic exam at enrollment can shorten or remove the longer waiting period.
Why this is sharper for cruciate. CCL injuries can come on fast. A dog who seemed fine on Monday can be limping by Friday. If the rupture happens during your waiting period, the whole condition is treated as pre-existing. Even a single earlier visit noting “occasional limping” can be cited later, because the sign is in the record. The fix is simple and entirely in your control: enroll before any of that shows up, and consider picking an insurer with a shorter cruciate waiting period.
How major insurers handle cruciate specifically
Cruciate conditions get unusually variable treatment. Here is how the major US providers handle it, ordered roughly from the shortest waiting period to the longest, based on their published policy language. Always confirm against your state-specific policy before buying, since orthopedic terms are one of the things that varies most by state.
| Insurer | Cruciate waiting period | Bilateral exclusion? | Exam waiver? |
|---|---|---|---|
| MetLife | No separate orthopedic wait. Cruciate falls under the standard 14-day illness wait. | Standard; verify your policy | Not needed |
| Pumpkin | 14 days for everything, including cruciate, hip, and cancer. | Yes | Not needed |
| Healthy Paws | 15 days in most states, the same as the standard illness wait. | Yes — cruciate is the only bilateral exclusion in the policy | Often waivable with a recent clinical exam; varies by state |
| Spot | 14 days. A pre-existing knee or ligament condition is permanently excluded, with no symptom-free reinstatement. | Yes | No |
| ASPCA | 14 days. Same permanent exclusion for a pre-existing knee or ligament condition. | Yes | No |
| Trupanion | 30-day illness wait, with an unusually broad 18-month look-back for prior signs. | Yes — cruciate is named in the bilateral conditions | No |
| Embrace | 6 months, reducible to 14 days with the Orthopedic Report Card vet exam at enrollment. | Yes | Yes — Orthopedic Report Card |
| Pets Best | 6 months. | Yes | No |
| Lemonade | 6 months for cruciate (30 days for other orthopedic conditions). | Yes | No |
| Nationwide | 12 months on most plans, the longest in the industry, though several states have no cruciate wait. | Yes | No |
A few things worth pulling out:
- MetLife, Pumpkin, and Healthy Paws have the shortest effective cruciate waits, in the 14 to 15 day range, well below the six-month industry norm. That gap matters most if your dog is a high-risk breed.
- Embrace’s Orthopedic Report Card is genuinely useful. A clean vet exam at enrollment collapses the six-month wait to the standard 14 days. For an at-risk breed, that is one of the more valuable mechanics in the industry.
- Spot and ASPCA permanently exclude a knee or ligament condition that was pre-existing, with no symptom-free reinstatement, even though they reinstate other curable conditions after a window. Their policies treat cruciate as a special case.
- Nationwide’s 12-month wait on most plans is the longest out there, so it isn’t the natural pick if cruciate protection is your main concern. A handful of states apply no cruciate wait, so check your own.
The bilateral exclusion, explained
This is the rule that catches the most owners off guard, so it’s worth being explicit. A bilateral condition affects both sides of the body, and cruciate is the textbook example, since dogs that tear one CCL often tear the other within a year or two.
The standard clause works like this: if either knee showed signs of cruciate injury before enrollment or during the waiting period, both knees are excluded, even if the second knee tears years later while the policy is active. Healthy Paws lists cruciate as the only bilateral exclusion in its policy. Trupanion names cruciate in its bilateral conditions. Spot, ASPCA, Embrace, Pets Best, MetLife, and Nationwide all apply a version of this clause too.
In practice:
- First CCL torn before enrollment: both knees are excluded.
- Limping or knee soreness before enrollment, even without a formal diagnosis: both knees can be excluded.
- Symptoms during the waiting period: both knees are typically excluded.
- Both knees clean at enrollment: if one tears later, the second knee is also covered if it tears in the future.
The takeaway is that enrollment timing on cruciate is unusually consequential. Once the first knee has anything in its record, the financial protection on the second knee is gone at almost every insurer. We go deeper on this in our pre-existing conditions breakdown.
What you’d actually pay
For a dog enrolled before any symptoms, past the waiting period, with a clean record on the relevant knee, here is roughly what a typical TPLO claim looks like:
| Item | Amount |
|---|---|
| TPLO surgery total bill (one knee, all-in) | $5,500 |
| Annual deductible | $250 |
| Reimbursement rate | 80% |
| Eligible amount after deductible | $5,250 |
| Insurance reimbursement (80% of eligible) | $4,200 |
| Your out-of-pocket | ~$1,300 |
Those aren’t hypothetical savings. MetLife, for example, publishes real cruciate claims in this range, including nearly $6,300 reimbursed on a $6,900 ACL surgery for a dog on a 90% policy. Without insurance, you’d simply pay the full bill each time.
What’s usually not covered
Even a well-chosen accident and illness plan typically leaves out:
- Pre-existing orthopedic signs, meaning any limping, stiffness, or favoring noted in the record before enrollment.
- Bilateral conditions, as covered above.
- Exam fees at some insurers. Healthy Paws excludes them; MetLife covers them on its standard plan, and Embrace, ASPCA, and Pets Best can include them on most plans, sometimes via an add-on. Verify in your policy.
- Joint supplements like fish oil and glucosamine are almost universally excluded, though MetLife can reimburse vet-prescribed supplements.
- Rehab at some insurers. Healthy Paws excludes it; Embrace and Spot cover it as standard; Trupanion covers it via the Recovery and Complementary Care rider.
- Genetic testing such as the cruciate-risk test isn’t typically reimbursed.
- Anything during the waiting period, where even a single symptom of lameness can become a permanent exclusion.
How to set up the cleanest coverage decision
Enroll before any orthopedic symptoms appear
For at-risk breeds such as Labs, Goldens, Rotties, Newfoundlands, and Mastiffs, every month of delay is a month a subtle limp could become a pre-existing exclusion. Peak diagnosis is age 6 to 10, but degenerative changes can start years earlier. The right time to enroll is at adoption, before your pet has the chance to develop any symptoms.
Pick a short orthopedic waiting period
Pumpkin (14 days), MetLife (cruciate under the 14-day illness wait), and Healthy Paws (15 days) are the shortest. Embrace’s six-month wait collapses to 14 days with the Orthopedic Report Card. A tear during a six-month wait is excluded for life, while the same tear after a 14-day wait is fully covered, so this is worth real money for an at-risk breed.
Use the vet-exam waiver if it’s available
Embrace’s Orthopedic Report Card needs a vet exam confirming no current orthopedic issues, completed within the first 14 days of the policy. The exam runs about $50 to $100 and cuts the cruciate wait from six months to 14 days. For a high-risk breed, that’s one of the highest-return moves available.
Read the bilateral exclusion clause specifically
Don’t assume any insurer will cover the second knee if the first was treated before enrollment. Almost none do. Embrace and Trupanion both offer post-enrollment medical-record reviews that document what may be excluded for your coverage. Use them.
Don’t overlook annual limits
A bad cruciate year, with surgery on both knees, full rehab, and complications, can top $15,000. Capped plans of $5,000 to $10,000 a year can be used up by one knee. Trupanion and Healthy Paws have no annual cap, though you’re paying for this unlimited plan through your premium cost. For an at-risk breed, compare these carefully.
Does pet insurance cover ACL surgery for cats?
Cats tear cruciate ligaments too, just far less often than dogs, usually from a fall or a hard landing rather than slow degeneration. The coverage rules are the same: an accident and illness plan covers feline cruciate repair as long as the injury isn’t pre-existing and the waiting period has cleared. Most major insurers that cover dogs, MetLife included, cover cats on the same terms, and MetLife’s Family Plan lets you put cats and dogs on one policy with one premium, if you’d prefer that over two individual policies.
Frequently asked questions
Does pet insurance cover ACL surgery for dogs?
Yes. Most accident and illness plans cover CCL surgery (TPLO, TTA, or lateral suture) as long as the injury isn’t pre-existing and the orthopedic waiting period has cleared. Accident-only plans usually cover sudden traumatic tears but not the more common gradual degenerative tears. Wellness plans don’t cover surgery at all.
What is the waiting period for ACL surgery coverage?
It varies sharply by insurer. Pumpkin (14 days) and Healthy Paws (15 days) apply only their standard illness wait to cruciate, and MetLife folds cruciate into its standard 14-day illness wait rather than applying a separate orthopedic wait. Embrace and Pets Best use 6 months (Embrace can reduce this to 14 days with a vet exam). Nationwide uses 12 months on most plans. Check the policy language for your state, since orthopedic waits can vary by jurisdiction.
Can I get pet insurance after my dog already tore their ACL?
You can buy a policy, but the torn cruciate will be classified as pre-existing and excluded, and the other knee will likely be excluded too under the bilateral clause. Your dog would still benefit from coverage for unrelated future conditions like cancer, organ disease, and accidents. The original injury and any future second-knee tear won’t be reimbursed.
Does pet insurance cover both knees if my dog tears both ACLs?
If both injuries occur after enrollment and the associated waiting period, yes, both knees are covered under most plans. The catch is the bilateral exclusion: if either knee showed signs before enrollment or during the waiting period, both are typically excluded. Healthy Paws lists cruciate as the only bilateral exclusion in its policy, and Spot, ASPCA, Embrace, and MetLife apply versions of the clause too.
How much does TPLO surgery cost?
TPLO surgery for dogs typically runs $3,500 to $7,500 per knee, with major-metro specialty hospitals at the higher end. The University of Wisconsin School of Veterinary Medicine cites $4,000 to $7,000 per knee. Counting pre-op imaging, rehab, and follow-up X-rays, a single TPLO often lands closer to $5,000 to $9,000 all-in.
Is TPLO surgery always covered by pet insurance?
TPLO is the standard procedure for cruciate tears in medium-to-large dogs and is covered under accident and illness plans at all major US insurers, assuming the injury isn’t pre-existing and the orthopedic waiting period has cleared. The same rules apply to TTA and lateral suture repair.
Are exam fees and rehab covered for ACL surgery?
It depends on the insurer. Healthy Paws excludes exam fees; MetLife covers them on its standard accident and illness plan; and Embrace, ASPCA, and Pets Best can include them on most plans, sometimes via add-on. Post-op rehab (hydrotherapy, laser therapy, physiotherapy) is standard at Embrace and Spot, available as a rider at Trupanion, and excluded at Healthy Paws. Always verify in the actual policy language.
The bottom line
Cruciate is one of the conditions where the right policy and good timing turn a five-figure surprise into a manageable bill. The two questions to ask any insurer before you enroll: what’s the orthopedic waiting period, and how does the bilateral exclusion work?
For at-risk breeds, the highest-leverage moves are enrolling before any orthopedic symptoms appear, choosing an insurer with a short cruciate wait (or one whose longer wait can be waived with a clean vet exam), and confirming the bilateral language in writing. MetLife is a strong starting point on both counts, thanks to its short cruciate wait and broad base plan, but the best fit depends on your dog’s breed, age, and your budget. Enroll early and the math works in your favor.
