If your vet has told you that your dog needs cruciate surgery, you’ve probably come across the term TPLO. For most dog owners, it’s an unfamiliar procedure with a lot of questions attached to it. This guide breaks down what TPLO surgery actually involves, what the recovery looks like week by week, and what to watch for at home so you can feel confident supporting your dog through it.
What Is TPLO Surgery?
TPLO stands for Tibial Plateau Leveling Osteotomy. It is the most widely performed surgical treatment for a torn cranial cruciate ligament (CCL) in dogs, which is the equivalent of an ACL tear in humans.
The CCL is one of the main stabilising ligaments inside your dog’s knee joint. When it tears, either partially or completely, the joint becomes unstable. The shin bone (tibia) slides forward with every step, causing pain and making it difficult for your dog to bear weight on the leg.
Rather than trying to replace the torn ligament directly, TPLO surgery changes the mechanics of the knee joint itself. The surgeon makes a curved cut in the top of the tibia, rotates the bone to a flatter angle, and secures it in the new position with a specialised bone plate and screws. Once healed, the knee is stable without needing a functional CCL.
Why Is TPLO the Recommended Option?
Cruciate tears in dogs are rarely a one-off trauma event. Most occur because the ligament has been gradually weakening over time, which means conservative management alone, such as rest and anti-inflammatories, typically provides only short-term relief. Without surgery, most dogs continue to deteriorate and develop significant arthritis in the affected joint.
TPLO is considered the gold standard for medium to large breed dogs, and for active dogs of any size, because it offers better long-term stability and a lower re-injury rate compared to older techniques. Studies consistently report that more than 90% of dogs return to normal or near-normal function after TPLO surgery.
What Happens During the Procedure?
TPLO surgery is performed under general anaesthetic by a veterinary surgeon. Here is a brief overview of what the procedure involves:
- Joint assessment: The surgeon opens the joint and inspects the CCL and the meniscus, the cartilage pad that cushions the knee.
- Meniscus check: If the meniscus is damaged, the torn portion is removed at the same time.
- Bone cut: A curved cut is made in the top of the tibia using a specialised saw.
- Rotation and fixation: The tibial plateau is rotated to reduce the angle, then a bone plate and screws are used to hold it in the new position.
- Closure: The joint and incision are closed in layers and a bandage is applied.
The procedure typically takes one to two hours. Most dogs go home the same day or the following morning.
TPLO Surgery Recovery Time: What to Expect Week by Week
Recovery from TPLO surgery takes approximately 12 weeks for the bone to fully heal, with complete return to strength often taking up to six months. Here is a general guide to what each phase looks like.
Weeks 1 and 2: Rest and wound care
Your dog will be groggy after anaesthetic and will need strict rest. Most dogs start to touch the operated leg to the ground within a day or two, which is a good sign, though they will be quite sore. Keep the incision clean and dry, check it daily for redness or discharge, and make sure your dog is wearing their e-collar to prevent licking.
Weeks 2 to 8: Controlled activity
Short, on-leash walks only during this phase. No running, jumping, rough play, or stair climbing without a ramp. Your dog will gradually put more weight through the leg, but the bone plate is still the main source of stability at this stage, so restricting activity is critical. Follow-up x-rays are usually scheduled around the 8-week mark to assess healing.
Weeks 8 to 12 and beyond: Gradual return to normal
Once x-rays confirm the bone has healed well, your vet will give you a plan for gradually increasing activity over the following weeks. Swimming and controlled exercise on soft ground are often recommended before returning to full off-lead activity. Most dogs are back to their normal routines by around four to six months post-surgery.
TPLO Surgery Aftercare: Supporting Your Dog at Home
What you do at home during recovery has a significant impact on the outcome. Here are the key things to stay on top of:
- Keep your dog confined to a small, safe area, a crate or a single room works well
- Short leash walks only, no off-lead time until cleared by your vet
- Check the incision site daily for swelling, heat, redness, or discharge
- Give all prescribed medications on schedule, including pain relief and antibiotics
- Keep the e-collar on at all times unless directly supervised
- Use ramps instead of stairs, and block access to furniture
- Attend all scheduled follow-up appointments and x-ray checks
Most dogs want to be more active than they should be, particularly as they start feeling better around weeks two to four. Sticking to the restrictions during this window is one of the most important things you can do.
Complications to Watch For After TPLO Surgery
TPLO is a safe and well-established procedure, but as with any surgery, complications can occur. Knowing what to look for helps you act quickly if something is not right.
Swelling and seroma
Some swelling around the incision in the first one to two weeks is normal. A seroma is a pocket of fluid that can develop under the skin near the surgical site. It usually appears as a soft, painless lump and often resolves on its own, but it should be assessed by your vet if it grows or does not improve within a week or two.
Infection
Signs of infection include increasing redness, warmth, discharge from the incision, or a foul smell from the wound. If you notice any of these, contact your vet promptly. TPLO plate infections are uncommon but require early treatment to prevent complications with the implant.
Implant concerns
The bone plate and screws used in TPLO surgery are designed to be permanent, but implant failure or irritation can occasionally occur. Signs include a sudden increase in lameness, swelling around the knee, or a return of symptoms after initial improvement. X-rays are the best way to assess the implant if you are concerned.
Is TPLO Surgery Worth It for Dogs?
For the majority of dogs, yes. The procedure has a well-documented success rate and gives most dogs a significantly better long-term outcome than conservative management alone. It is worth understanding, however, that TPLO does not prevent arthritis from developing in the affected joint over time. It slows the progression and reduces pain, but ongoing joint management, including weight control, appropriate exercise, and joint supplements, remains important for life.
The earlier surgery is performed after a CCL tear, the less joint damage has occurred and the better the long-term result tends to be.
