How Much Does Dog ACL (TPLO) Surgery Cost in 2026?
A torn cruciate ligament is the most common major orthopedic injury in dogs, and TPLO is the surgery most vets recommend for medium and large breeds. The headline number: according to CareCredit’s April 2026 veterinary cost analysis, TPLO surgery averages $3,525 per knee in the US, with regional prices ranging from about $2,793 to $6,417. Specialty hospitals in major metro areas can quote $7,500 or more. Once diagnostics, follow-up care and rehabilitation are included, the full episode typically lands between $2,900 and $8,100. This guide breaks the bill down line by line and shows exactly what insurance pays toward it.
The Full TPLO Bill, Line by Line
| Cost item | Typical range | Notes |
|---|---|---|
| Diagnosis: exam, sedation and X-rays | $250 to $600 | The ligament does not show on X-rays, but joint swelling and arthritis do; images also plan the surgery |
| Pre-surgery blood work | $100 to $200 | Anaesthetic safety screening |
| TPLO surgery, one knee | $2,793 to $6,417 | CareCredit’s 2026 regional range; national average $3,525; includes plate, screws, anaesthesia and usually one hospital night |
| Post-surgery medication and rechecks | $50 to $300 | Pain relief, antibiotics where used, and follow-up X-rays are sometimes billed separately |
| Physical rehabilitation | $0 to $1,000 | Optional but recommended; hydrotherapy and laser sessions run $50 to $90 each |
| Total episode | $2,900 to $8,100 | Per knee; a second knee roughly doubles it |
Dog size is the biggest single driver inside those ranges. More anaesthetic, a larger plate and longer surgery time push giant breeds to the top, which is one reason the German Shepherd and Labrador Retriever profiles carry higher premiums: cruciate claims are priced into their risk from the start.
TPLO vs TTA vs Lateral Suture
TPLO (tibial plateau leveling osteotomy) cuts and rotates the top of the shin bone so the knee stays stable without the torn ligament. It has the strongest evidence for returning large, active dogs to full function. TTA (tibial tuberosity advancement) changes the forces on the knee a different way and prices similarly, usually within a few hundred dollars of TPLO. The budget option is the lateral or extracapsular suture, a strong artificial fibre placed outside the joint, typically $1,000 to $3,000. It suits small, calm dogs best; in large or very active dogs the suture stretches and fails more often, and a failed repair can mean paying for TPLO anyway. Published outcome data put significant improvement at 85% to 90% of surgical cases across techniques, with overall complication rates around 10% to 20%.
The Second Knee Problem
Budget for the possibility of two bills. Studies of cruciate disease consistently find that a large share of dogs, often quoted at around 40% to 60%, tear the opposite ligament within one to two years of the first, because the same body shape and forces caused both injuries and the healthy leg works harder during recovery. Ask your surgeon about the other knee at every recheck, keep the dog’s weight down, and follow the rehab plan; those three steps are the owner’s only real leverage against a second $3,500 bill.
What Insurance Pays Toward TPLO
On a $4,200 TPLO episode with a $500 deductible and 80% reimbursement, the insurer pays ($4,200 minus $500) x 80%, which is $2,960, leaving you $1,240. On a $250 deductible at 90%, the payout rises to $3,555. Cruciate surgery is exactly the claim class accident and illness policies are built for, but it comes with two traps. The first is the orthopedic waiting period: several major carriers will not cover cruciate problems for the first 6 months of a policy, which is why our waiting periods by company table matters before you buy. The second is the bilateral clause: if one knee was injured or showed symptoms before the policy started, some carriers treat the other knee as the same pre-existing condition. Our pre-existing conditions guide explains how that clause is applied.
Recovery itself takes 8 to 12 weeks of restricted exercise, with most dogs walking comfortably well before the bone has fully healed. Budget the time as honestly as the money: a TPLO on a young, powerful dog is as much a logistics project as a financial one. For the wider picture of surgical pricing, see our average vet costs hub.
Frequently Asked Questions
How much does TPLO cost for a large dog?
Large and giant breeds sit at the top of the range. CareCredit’s 2026 data puts the TPLO average at $3,525 across all sizes, with regional quotes to $6,417 and specialty hospitals in expensive metros reaching $7,500 or more. A giant breed at a referral centre should budget toward $5,000 to $7,000 for the operation alone.
Is the cheaper lateral suture ever the right choice?
Yes, for small, older or calm dogs, and where budget is the hard constraint, it can work well and typically costs $1,000 to $3,000. For large, young or athletic dogs, surgeons usually steer owners to TPLO or TTA because suture failure rates climb with body weight and activity, and a second surgery erases the saving.
Does pet insurance cover both knees?
Generally yes, if both injuries happen after all waiting periods and neither knee showed symptoms before the policy started. Watch for bilateral-condition clauses, which can link the second knee to the first if the first was pre-existing, and remember both claims share your annual deductible and annual limit in the same policy year.
How long is TPLO recovery?
Most dogs put weight on the leg within days, but full bone healing takes 8 to 12 weeks of strict rest, short leash walks and controlled rehab. Follow-up X-rays at around 8 weeks confirm healing. Rushing exercise is the most common owner-caused complication.
