If your dog has been diagnosed with a cranial cruciate ligament (CCL) tear, there’s a good chance your veterinarian mentioned TPLO surgery. It’s one of the most commonly performed orthopedic procedures in dogs, and for most medium and large breeds, it’s considered the gold standard for restoring stability to the knee.
Hearing that your dog needs surgery can feel overwhelming, so this guide walks through what TPLO actually is, how it works, and what recovery looks like week by week, so you can make a confident, informed decision about your dog’s care.
What Is TPLO Surgery?
TPLO stands for tibial plateau leveling osteotomy. Rather than replacing the torn ligament, the procedure changes the mechanics of the knee itself so the ligament is no longer needed.
In a healthy knee, the CCL prevents the femur from sliding backward down the sloped top of the tibia. When the ligament tears, that slope allows the joint to shift with every step, which causes pain, instability, and progressive arthritis.
During TPLO surgery, the surgeon makes a curved cut in the top of the tibia, rotates the bone segment to level out the slope, and secures it in its new position with a bone plate and screws. Once the slope is level, the knee stays stable when your dog bears weight, without relying on the damaged ligament at all.
Why TPLO Is Often Recommended Over Other Options
There are several surgical techniques for CCL injuries, including lateral suture stabilization and tibial tuberosity advancement (TTA). TPLO is frequently the first choice for active dogs and dogs over about 40 pounds because it:
- Provides excellent long-term stability, even in athletic and working dogs
- Allows most dogs to begin bearing weight on the leg within days of surgery
- Slows the progression of arthritis compared to untreated or unstable knees
- Has decades of research and consistently high success rates behind it
Your surgeon will evaluate your dog’s size, age, activity level, and the condition of the joint before recommending the approach that fits best. Not every dog needs a TPLO, and a thorough orthopedic consultation is the right place to start.
What Happens Before Surgery
An accurate diagnosis comes first. At a specialty hospital, your dog’s evaluation typically includes:
- A comprehensive orthopedic examination and gait assessment
- Sedated radiographs (X-rays) to measure the tibial plateau angle and plan the procedure
- Bloodwork to confirm your dog is a safe anesthesia candidate
- In some cases, advanced imaging to evaluate the meniscus and surrounding structures
Precise measurements matter. The rotation performed during TPLO is planned to the millimeter based on your dog’s individual anatomy, which is one reason board-certified surgical teams and advanced diagnostic imaging make a real difference in outcomes.
What Happens During Surgery
TPLO is typically performed in a single procedure lasting about one to two hours. Before making the bone cut, the surgeon inspects the inside of the joint and addresses any damage to the meniscus, the cartilage cushion that is torn in a significant number of CCL cases. The tibia is then cut, rotated to the pre-planned angle, and stabilized with a locking bone plate.
Most dogs stay in the hospital overnight for pain management and monitoring, then go home the following day with medications and detailed recovery instructions.
TPLO Recovery: A Week-by-Week Look
Recovery is where committed owners make the biggest difference. Here’s what a typical timeline looks like:
Weeks 1 to 2. Strict rest. Short leash walks for bathroom breaks only, no stairs, no jumping, no rough play. Many dogs begin touching the toe down or lightly bearing weight within the first few days. Incision care and pain management are the priorities.
Weeks 2 to 8. Gradually longer, controlled leash walks as directed by your surgical team. The bone is healing during this window, so activity restriction still matters even when your dog starts feeling much better. Feeling better and being healed are not the same thing.
Week 8 and beyond. Recheck radiographs confirm the bone has healed. Once your surgeon gives the green light, your dog transitions back to normal activity over several weeks, often with a structured strengthening plan.
Most dogs return to full, comfortable activity within four to six months, and many athletic dogs return to running, hiking, and sport.
The Role of Rehabilitation
Formal rehabilitation isn’t just a nice extra. Guided exercises, underwater treadmill work, and progressive strengthening help dogs rebuild muscle they lost while favoring the leg and can shorten the road back to full function.

What Happens If a CCL Tear Isn’t Treated?
An unstable knee doesn’t heal on its own in most dogs. Without treatment, the joint continues to shift, arthritis develops rapidly, and the meniscus is at ongoing risk of tearing. Many dogs with an untreated CCL injury on one side also go on to tear the other, partly because they overload the healthy leg. Early surgical stabilization protects the joint and your dog’s long-term mobility.
If you’re still in the “is it really torn?” stage, our guide on why your dog might be limping covers CCL injuries alongside other common causes of lameness.
Choosing the Right Surgical Team
TPLO outcomes depend heavily on surgical planning, technique, and follow-through. When evaluating where to have your dog’s procedure performed, it’s reasonable to ask about the team’s experience with TPLO, the imaging used for surgical planning, anesthesia monitoring protocols, and whether rehabilitation is available on site.
At Kinetic Veterinary Specialists, our surgical team performs TPLO with advanced imaging, dedicated anesthesia monitoring, and in-house rehabilitation, all under one roof in Clermont, Florida. Families come to us from across Central Florida and beyond, and we’re glad to coordinate care for out-of-area patients as well. Learn more about our Orthopedic Surgery services.
Frequently Asked Questions
How long does TPLO recovery take?
Most dogs are using the leg well within a few weeks, but full bone healing takes about 8 to 12 weeks, confirmed with recheck X-rays. A complete return to unrestricted activity typically happens around four to six months after surgery.
Can my dog walk after TPLO surgery?
Most dogs are using the leg well within a few weeks, but full bone healing takes about 8 to 12 weeks, confirmed with recheck X-rays. A complete return to unrestricted activity typically happens around four to six months after surgery.
What is the success rate of TPLO surgery?
TPLO has one of the highest success rates of any orthopedic procedure in dogs, with the large majority of patients returning to normal or near-normal function. Your surgeon will discuss expectations specific to your dog’s case.
How much does TPLO surgery cost?
Cost varies based on your dog’s size, imaging needs, and any additional joint damage found at surgery. Contact our team at (352) 553-2774 for a consultation and a detailed estimate for your dog.
Is my dog too old for TPLO surgery?
Age alone is rarely the deciding factor. Overall health, activity level, and anesthesia risk matter more. Many senior dogs do very well with TPLO and enjoy years of comfortable mobility afterward.
