How Much Does Dog ACL Surgery Cost?
TPLO, the most common repair for medium and large dogs, averages $3,525 per knee, with state averages from $2,793 to $6,417 in the 2025 Synchrony cost study published by CareCredit. Expect the full bill, with X-rays, bloodwork, medication and rechecks, to land several hundred dollars above the surgery figure.
Dogs do not have an ACL exactly as humans do; the equivalent ligament is the cranial cruciate ligament, or CCL, and it stabilizes the knee every time the dog bears weight. When it tears, partially or fully, the knee slides painfully with each step. Unlike a sprain, a torn cruciate does not heal itself into a stable joint, which is why this injury leads to surgery more often than almost any other orthopedic problem.
There are several operations, and the right one depends mostly on your dog's size, age and activity. TPLO (tibial plateau leveling osteotomy) is the benchmark procedure the cost study prices. Simpler suture repairs suit many small dogs. The sections below keep the study's TPLO figures as the anchor and explain where the rest of the bill comes from.
What the price includes
- The orthopedic workup. An exam under manipulation, often with sedation, and knee X-rays to confirm the diagnosis and plan the surgery. X-ray series average $172 to $213 at daytime prices in the study.
- Pre-anesthetic bloodwork. A CBC and chemistry panel (study averages $104 and $164) before a long anesthetic.
- The surgery and implant. For TPLO, a curved cut in the shin bone is rotated and fixed with a plate and screws that stay in for life. The study's $3,525 average covers the operation itself at a typical practice.
- Anesthesia, monitoring and hospital time. Usually a day of hospitalization, sometimes a night, with IV fluids and pain control.
- Aftercare basics. Take-home pain medication, recheck appointments and follow-up X-rays to confirm the bone has healed, typically around eight weeks. Whether these sit inside the quote varies by surgeon, so ask.
What pushes the price up or down
- Technique. TPLO averages $3,525 in the study and is the standard recommendation for medium, large and active dogs. Lateral suture repairs, which stabilize the knee with a strong line outside the joint, are generally quoted lower and are usually reserved for smaller or older, quieter dogs. Your surgeon should explain why they are recommending one over the other for your dog.
- Who operates. A board-certified surgeon at a specialty hospital charges more than a general practitioner with orthopedic training, and complex or revision cases belong with the specialist. Teaching hospitals often sit between the two.
- Size. Bigger dogs need bigger implants, more anesthesia and more medication, and they load the repair harder during recovery.
- Region. The study's state averages for TPLO run from $2,793 to $6,417, the widest spread of any procedure in this section, because specialist availability varies so much by area.
- The other knee. Surgeons commonly warn that a dog that tears one cruciate has a substantial chance of tearing the other within a couple of years. It is the main reason this injury reshapes a family's dog budget, and worth asking your surgeon to state plainly for your dog.
- Rehabilitation. Formal rehab, underwater treadmill sessions and follow-up imaging are sometimes inside the quote and sometimes not. Budget for them as extras until told otherwise.
Ways to pay less without cutting care
- Get the teaching hospital quote. University hospitals perform TPLO regularly, with residents operating under specialist supervision, and frequently price below private specialty centers. For a planned (not emergency) surgery, the waiting list is usually manageable.
- Ask for an all-in written estimate. The single most useful money step: a quote that lists the surgery, imaging, bloodwork, hospital time, medication and follow-up X-rays line by line, so quotes from two surgeons can be compared like for like.
- Insurance only helps if bought early. Cruciate injuries are commonly excluded as pre-existing once a dog has shown signs in either knee, and many policies impose a specific waiting period for cruciate coverage. This is the injury that sells insurance to everyone who has paid for it once.
- Weight management is real treatment. Every pound off an overweight dog unloads both knees, the repaired one during rehab and the intact one for the rest of its life. It is free, and surgeons will tell you it changes outcomes.
- Discuss conservative management honestly. For a small, elderly or medically fragile dog, strict rest, weight loss and pain management are sometimes a reasonable plan. It is a quality-of-life decision to make with your vet, with eyes open about arthritis developing in the unstable joint.
Is ACL surgery optional?
For a young, large, active dog, effectively no: an unstable knee means pain now and progressive arthritis, and surgery is the only route back to normal function. For small dogs, and for old or unwell dogs where anesthesia itself is the risk, managed non-surgical care can be a legitimate choice rather than a failure to treat. What is not a real option is doing nothing at all: a dog limping on a torn cruciate needs at minimum pain relief, rest and a weight plan, agreed with your vet.
Frequently asked questions
How much does TPLO surgery cost for a dog?
The 2025 Synchrony study published by CareCredit averages $3,525 per knee nationally, with state averages from $2,793 to $6,417. Specialist hospitals in large cities sit above the average; teaching hospitals often below it.
What is the difference between ACL and CCL in dogs?
They are the corresponding ligament in the knee. Human anatomy calls it the anterior cruciate ligament; in dogs it is the cranial cruciate ligament. Owners and many vets say 'ACL' out of habit, and TPLO is the operation most often used to repair the damage either way.
Are there cheaper alternatives to TPLO?
A lateral suture (extracapsular) repair is usually quoted lower and can work well for small, light or less active dogs. It is generally not recommended as a substitute for TPLO in large, athletic dogs, where the suture can stretch or fail. Your surgeon's recommendation should be based on your dog's size and lifestyle, not just price.
What is not included in the surgery quote?
Commonly billed separately: the diagnostic X-rays, pre-op bloodwork, take-home medication beyond the first supply, follow-up X-rays at about eight weeks, and formal rehabilitation. At study averages, X-rays plus bloodwork alone add roughly $440 to $480.
How long is recovery from TPLO?
Most programs run about 8 to 12 weeks: strict rest and short leash walks at first, a bone-healing X-ray around eight weeks, then a graded return to normal exercise. Rushing the middle weeks is the most common way owners undo a good repair.
Will my dog tear the other ACL too?
It happens often enough that surgeons routinely warn about it. The honest answer for your dog depends on breed, weight and conformation. Keeping your dog lean is the one protective step fully in your control.
