Dog ACL surgery typically costs between $1,500 and $6,000, depending on the surgical technique, your dog’s size, and where you live. That range covers everything from the simplest stabilization method to the most advanced bone-cutting procedures, but the final bill often climbs higher once you factor in imaging, medications, and rehabilitation.
Cost by Surgery Type
Three main surgical options exist for a torn cruciate ligament in dogs, and each comes with a different price tag.
Lateral suture repair (extracapsular repair) is the least expensive option, running $1,500 to $3,000. The surgeon places a strong synthetic line outside the joint to stabilize the knee while scar tissue forms. It works best for smaller dogs, generally those under 50 pounds, though some surgeons use it for medium-sized dogs with good results.
TPLO (tibial plateau leveling osteotomy) is the most commonly recommended procedure for medium and large dogs, costing $3,000 to $6,000. The surgeon cuts and rotates a portion of the shinbone, then secures it with a metal plate and screws. This changes the angle of the knee joint so the dog no longer needs the ligament for stability. It’s considered the gold standard for active, larger dogs because the joint mechanics are fundamentally improved rather than just reinforced.
TTA (tibial tuberosity advancement) falls in the $3,000 to $5,000 range. Similar to TPLO, it involves cutting the shinbone, but the bone is advanced forward and anchored with metal implants instead of rotated. Outcomes are comparable to TPLO for many dogs, and some surgeons prefer it depending on the anatomy of the knee.
Your dog’s weight pushes the price within each range. Larger dogs need bigger implants, more anesthesia, and longer surgical time. A TPLO on a 40-pound dog will land closer to $3,000, while the same procedure on a 120-pound dog can easily hit $5,000 or more.
What’s Included in the Surgical Quote
Most surgical estimates bundle the core expenses together: the procedure itself, anesthesia, pre-surgical bloodwork, X-rays, and take-home medications. Some specialty practices also include an epidural (for better pain control during and after surgery) and a set number of rehabilitation sessions in their package price. At one surgical referral center, for example, the TPLO estimate includes radiographs, an epidural, and six rehab sessions as standard.
What’s often not included, or not obvious in the initial quote, are the costs that accumulate in the weeks after surgery. Pre-surgical consultations with a specialist, if your regular vet doesn’t perform orthopedic surgery, can add $200 to $500 before you even book the procedure. And if your dog has other health issues that complicate anesthesia or healing, expect the total to rise.
Post-Surgery Costs That Add Up
The surgery bill is the biggest single expense, but recovery isn’t free. Most dogs need pain medication and anti-inflammatory drugs for several weeks. Common prescriptions like anti-inflammatory tablets and nerve pain medications are relatively affordable on a per-dose basis, but a larger dog taking higher doses over six to eight weeks can easily run $50 to $150 in medications alone. Some dogs also need a mild sedative to keep them calm during crate rest, which adds a smaller but real cost.
Follow-up X-rays are standard at roughly 8 and 12 weeks after surgery to confirm the bone is healing properly, especially after TPLO or TTA where the bone was cut. Each set of radiographs plus an exam typically costs $150 to $400, depending on your clinic.
Physical rehabilitation makes a meaningful difference in how quickly and fully your dog recovers. Sessions generally run $50 to $100 each, and a typical recovery plan involves one to two sessions per week for six to twelve weeks. If rehab isn’t bundled into your surgical quote, that’s another $300 to $1,200 over the recovery period. Underwater treadmill work and therapeutic exercises help rebuild muscle and restore range of motion, so skipping rehab entirely isn’t ideal, especially for athletic or working dogs.
What If Something Goes Wrong
Complications after cruciate surgery are uncommon but not rare, and they can be expensive. Infection at the surgical site sometimes requires additional rounds of antibiotics, and in severe cases, the metal implants may need to be removed. Plate removal surgery averages $800 to $2,500, covering anesthesia, the procedure, and post-operative care.
Implant loosening, poor bone healing, or persistent instability can require revision surgery, which is more complex than the original operation and costs accordingly. Revision TPLO involves replacing damaged hardware, repositioning the bone cut, or addressing infection, all of which mean a longer recovery and stricter post-operative management. While there’s no single published figure for revision costs, expect them to match or exceed the original surgical bill.
One financial reality that catches many owners off guard: roughly 40 to 60 percent of dogs that tear one cruciate ligament will eventually tear the other. If your dog ends up needing surgery on both knees, you’re looking at doubling most of these costs, though usually months apart.
Non-Surgical Alternatives and Their Costs
Not every dog is a surgical candidate. Very small dogs, senior dogs with other health problems, or cases where owners can’t afford surgery may benefit from conservative management. This typically combines strict rest, anti-inflammatory medication, weight management, and a custom knee brace.
A custom orthotic brace designed specifically for cruciate injuries runs about $895 for one knee. If both knees need bracing, a bilateral set costs around $1,690. These are molded to your dog’s leg and provide external stability, though they don’t restore the joint mechanics the way surgery does. Off-the-shelf braces are cheaper ($100 to $300) but far less effective because they don’t fit precisely.
Conservative management works best for dogs under 30 pounds. Larger dogs generally do poorly without surgery because their weight puts too much stress on the unstable joint, leading to progressive arthritis and muscle loss.
Pet Insurance and Payment Options
If your dog already has pet insurance when the injury happens, cruciate surgery is typically covered under accident or illness plans. The key detail is timing: most insurers impose a specific waiting period for orthopedic conditions. Lemonade, for instance, requires a 30-day waiting period for orthopedic issues like cruciate injuries, compared to just 14 days for general illnesses. This longer window exists because ligament problems often develop gradually or have genetic components, and insurers want to ensure they’re covering new injuries rather than pre-existing ones.
That waiting period applies regardless of your dog’s age. Even a two-month-old puppy must wait the full 30 days before orthopedic coverage kicks in. If you’re considering insurance, signing up well before any signs of limping is the only way to guarantee coverage. Once a cruciate tear is diagnosed or even suspected, it becomes a pre-existing condition that no new policy will cover.
For owners paying out of pocket, many veterinary practices offer payment plans through third-party financing like CareCredit or Scratchpay. Some specialty surgical centers also offer tiered pricing based on dog size, which at least makes the cost more predictable upfront. Asking for a detailed written estimate before scheduling surgery, and confirming what follow-up care is and isn’t included, prevents the most common billing surprises.
