TPLO surgery is a common procedure to repair a torn cranial cruciate ligament (CCL) in dogs. This surgery stabilizes the knee joint, allowing dogs to regain mobility and reduce pain. Understanding the cost of TPLO surgery is important for pet owners planning their dog's treatment.
Costs vary widely in Perth due to factors like the surgeon's experience, diagnostic tests, dog size, implants used, and post-surgery rehabilitation. This article covers typical price ranges, what is included and excluded, key cost drivers, and tips for owners in Perth.
Typical TPLO Surgery Cost in Perth
Pricing for TPLO surgery in Perth depends on the clinic, surgeon expertise, and your dog's size. Prices can vary significantly between providers.
- Low estimate in Perth — Some clinics offer TPLO surgery starting around AUD 3,500. These lower prices may reflect less experienced surgeons or fewer included services. Owners should consider potential compromises such as limited post-op care or older implant technology.
- Average cost range in Perth — Most pet owners pay between AUD 4,500 and AUD 6,000. This range typically covers surgery by experienced veterinarians, standard implants, and basic post-operative care, representing the common market rate.
- High-end TPLO specialists in Perth — Premium clinics with board-certified surgeons and advanced surgical equipment may charge AUD 7,000 or more. These providers often include comprehensive diagnostics, high-quality implants, and extensive rehabilitation support.
What the Cost Usually Covers
TPLO surgery packages generally include several key components essential for a successful outcome.
- Surgery itself — The procedure involves cutting and rotating the tibia to stabilize the knee. This complex surgery requires skill and specialized tools, contributing significantly to the overall cost.
- Anaesthesia + monitoring — Safe anaesthesia and continuous monitoring during surgery are critical. These services ensure your dog’s safety and comfort, adding to the price.
- Implants/plates — Stainless steel or titanium plates and screws are used to hold the bone in place. Titanium implants are more expensive but may offer better durability and biocompatibility.
- Post-op care and follow-up exams — Follow-up visits to monitor healing and manage pain are usually included. These visits help ensure a smooth recovery and address any complications early.
What Might Not Be Included
Some costs are often overlooked when budgeting for TPLO surgery in Perth.
- Pre-surgical diagnostics — X-rays, blood tests, and other diagnostics before surgery may be billed separately and can add several hundred dollars to the total cost.
- Post-surgical rehab therapy — Physical therapy or hydrotherapy sessions to aid recovery are usually extra and can be costly but improve outcomes significantly. For more details, see physical therapy after TPLO.
- Medications beyond standard pain control — Additional medications for infection or inflammation might be required and are not always included in the initial quote.
- Additional cost if both legs need surgery — Bilateral TPLO surgeries double many costs and may require staged procedures, increasing overall expenses.
Key Cost Drivers in Perth
Even within Perth, TPLO surgery prices vary due to several factors.
- Dog size/weight — Larger dogs require bigger implants and longer surgery times, increasing costs.
- General vet vs board-certified surgeon — Specialists with advanced training often charge more but may offer better outcomes and fewer complications.
- City living costs + overhead in Perth — Clinic rent, staff salaries, and equipment costs in Perth influence pricing.
- Implant brand and surgical technology used — High-quality implants and modern surgical tools add to the expense but improve success rates.
- Complication or infection risk — Cases with complications require additional treatment and monitoring, raising total costs.
Tips for Pet Owners in Perth
Planning financially for TPLO surgery helps avoid surprises and ensures your dog receives the best care.
- Ask for a detailed itemised estimate — Request a breakdown of all expected costs to understand what you are paying for and avoid hidden fees.
- Clarify if quote is for one leg or both — Confirm whether the price covers surgery on one knee or both, as this significantly affects the total cost.
- Explore pet insurance or financing options — Insurance may cover part of the surgery. Financing plans can help manage payments over time. Learn more about pet insurance and TPLO coverage.
- Compare multiple clinics and ask about success rates — Research different providers’ reputations and outcomes to choose the best option for your dog.
- Ask about rehab or physiotherapy packages — Some clinics offer bundled rehab services that can save money and improve recovery. See TPLO recovery tips for guidance.
Conclusion
TPLO surgery is a significant financial commitment for dog owners in Perth. Costs vary widely depending on clinic, surgeon, and dog-specific factors. Careful planning and understanding of pricing help prevent unexpected expenses.
Comparing quotes and confirming what is included before choosing a clinic ensures you make the best decision for your pet’s health and your budget.

Things to know

Modified Maquet Procedure vs TPLO Surgery
The Modified Maquet Procedure (MMP) is an evolution of the Tibial Tuberosity Advancement (TTA) that uses a titanium foam wedge instead of a cage to advance the tibial tuberosity.
It has been positioned as a less invasive, faster-to-perform alternative to TPLO for dogs with CCL rupture.
Published clinical evidence shows both procedures produce good outcomes, with TPLO demonstrating a slight advantage in objective gait analysis at 3 months.
Quick answer: A prospective randomized study found TPLO achieves 93.9% of normal peak vertical force vs 89.4% for MMP at 6 months — no significant difference in complications or OA progression. MMP is less invasive, faster, and generally less expensive. Both are appropriate for medium-to-large breed dogs.
Key takeaways
- TPLO achieves 93.9% of normal ground reaction force at 6 months vs 89.4% for MMP — numerically superior but not statistically significant
- No significant difference in major complications or OA progression was found between TPLO and MMP in the comparative study
- MMP is less invasive and faster to perform: a titanium foam wedge and partial osteotomy instead of TPLO's full proximal tibial cut
- MMP is generally less expensive than TPLO: shorter surgical time and different implant costs reduce the procedure price
- Early partial weight-bearing may occur sooner after MMP due to less invasive fixation and the partial osteotomy
- TPLO has a much larger evidence base: 25+ years of data vs limited MMP evidence
How each procedure works
TPLO (Tibial Plateau Leveling Osteotomy)
TPLO addresses CCL rupture by making a curved osteotomy through the proximal tibia and rotating the tibial plateau to approximately 5 degrees.
This changes joint biomechanics so the stifle is stable during weight-bearing without a functioning CCL. The osteotomy is held in place with a bone plate and screws.
Modified Maquet Procedure (MMP)
MMP is an adaptation of TTA in which the tibial tuberosity is advanced cranially by making a partial osteotomy in the tibial crest.
A porous titanium foam wedge is inserted into the gap and a fixation staple holds the construct in position.
The cranial advancement of the tuberosity repositions the patellar tendon to neutralize the cranial thrust that occurs in the CCL-deficient stifle the same biomechanical principle as TTA, with different implants.
Animal Works Veterinary Surgery describes MMP as using improved implants and surgical techniques designed to reduce operating time and minimize complications compared to standard TTA.
The titanium foam wedge promotes bone ingrowth and healing without the need for a cage or plate system. Bone healing in the MMP osteotomy site is typically complete at 90 days radiographically.
Clinical evidence: TPLO vs MMP
Primary comparative study
PubMed (prospective randomized controlled study, 61 dogs, 76 joints): dogs were treated with TPLO (n=30, 41 joints) or MMP (n=31, 35 joints) and compared with healthy controls.
Outcomes were assessed by clinical examination, radiography, and treadmill force plate gait analysis at 6 weeks, 3 months, and 6 months.
Results at 6 months:
- TPLO: 93.9% of normal peak vertical force (PVF), 85.9% of normal vertical impulse (VI)
- MMP: 89.4% of normal PVF, 79.9% of normal VI
At 3 months, significantly more TPLO patients were within the reference range for healthy dogs on peak vertical force. By 6 months, the difference was not statistically significant.
No significant difference was found in major complications or OA progression at any time point.
Conclusion from the study: "Although no significant differences were found between the surgical methods, TPLO patients showed superiority with regard to clinical outcome."
MMP standalone study
PMC (35 dogs, unilateral CCL rupture, MMP): significant improvement in ground reaction forces at all time intervals. At 90 days, 54.2% of patients had a Symmetry Index suggesting normal gait.
Complete bone healing on radiographs at 90 days. Major complication rate: 8.5% (3 of 35), minor complication rate: 2.8%.
Practical comparison
| Factor | MMP | TPLO |
|---|---|---|
| Mechanism | Tibial tuberosity advancement (titanium wedge) | Tibial plateau rotation (bone plate) |
| Invasiveness | Less invasive (partial osteotomy) | More invasive (full proximal tibial osteotomy) |
| Surgery time | Shorter | Longer |
| Bone healing (radiographic) | Approximately 90 days | 8 to 12 weeks |
| Objective outcomes at 6 months | 89.4% PVF | 93.9% PVF |
| Major complication rate | 8.5% in MMP standalone study | 14 to 34% literature range for TPLO |
| Cost | Generally lower | Generally higher |
| Early weight-bearing | May be earlier | Typically from 10 to 14 days |
| Evidence base | Limited (newer procedure) | Extensive (25+ years) |
Which dogs are best suited to each?
MMP is often chosen for:
- Medium and large breed dogs where a less invasive approach is preferred
- Cases where surgical time is a clinical consideration
- Practices experienced in MMP technique
- Dogs where cost is a factor
TPLO is typically recommended for:
- Large and giant breed dogs with high joint loads
- Dogs with steep tibial plateau angles where TPLO provides more precise biomechanical correction
- Cases where the largest available evidence base is preferred
- Surgeons with established TPLO experience
Animal Hospital of Adel notes that both surgeries are effective, with MMP being less invasive, less expensive, and quicker to perform.
Walkerville Vet's evidence review concludes that TPLO gives slightly better objective results and that MMP is expected to outperform standard TTA, though more evidence is needed.
For the full TPLO pros and cons, see TPLO surgery pros and cons for dogs. For the full alternatives overview, see alternatives to TPLO surgery for dogs.
Frequently asked questions
Is MMP as effective as TPLO for large dogs?
The evidence suggests TPLO has a slight advantage at 3 months, with equivalent outcomes by 6 months in the primary comparative study.
Most surgeons still prefer TPLO for large and giant breeds due to the larger evidence base and slightly superior short-term objective results. MMP is appropriate for many large dogs in experienced hands.
How much cheaper is MMP than TPLO?
MMP is generally less expensive than TPLO due to shorter surgical time and different implant costs. The specific difference varies by practice, region, and surgeon.
Ask your veterinarian for a direct cost comparison for your dog's specific case.
What is the complication rate for MMP compared to TPLO?
The MMP standalone study reported an 8.5% major complication rate. TPLO complication rates across the literature range from 14 to 34%.
However, these figures come from different study populations and settings, making direct comparison difficult. Neither procedure is free of risk.
How long does MMP recovery take compared to TPLO?
Both procedures require 8 to 12 weeks of restricted activity, though MMP's less invasive partial osteotomy may allow earlier partial weight-bearing in some dogs.
Full activity return for both procedures is typically at 4 to 6 months.
Can a dog have TPLO if MMP fails?
Yes. TPLO can be performed as a revision if MMP results in ongoing instability or poor function. The converse is less common.
Discuss revision options with an orthopedic specialist if your dog is not progressing as expected after MMP.

Arthritis After TPLO Surgery in Dogs
TPLO surgery is not a cure for arthritis it is a mechanical correction that stabilizes the stifle and slows the rate at which arthritis progresses.
Understanding what happens to the joint long-term is one of the most important conversations an owner can have with their veterinarian.
Quick answer: All dogs develop some OA after CCL rupture, and it continues after TPLO. Research shows OA progresses more slowly after TPLO than after TTA or non-surgical management. Long-term management includes weight control, joint supplements, NSAIDs, and controlled exercise.
Key takeaways
- OA develops in all dogs with CCL rupture: TPLO stops instability that accelerates OA but does not eliminate existing arthritis
- TPLO slows OA progression: a PubMed study found OA progressed significantly more after TTA than TPLO (p=0.003)
- Radiographic OA scores increase significantly at 24 months post-TPLO in dogs with complete CCL rupture
- MedVet confirms: all dogs develop arthritis within weeks of ligament tearing, but knee stabilization slows the progression
- Weight management is the most impactful owner intervention: excess weight increases stifle load and accelerates cartilage wear
- Long-term NSAID use requires veterinary guidance: kidney and liver monitoring is required for dogs on chronic NSAID therapy
Why arthritis develops after TPLO
CCL rupture damages the joint before surgery even begins. The instability the tibia sliding forward under the femur with each step causes:
- Cartilage microtrauma from abnormal loading
- Synovial membrane inflammation, releasing enzymes that break down cartilage
- Medial meniscus injury (30 to 40% of CCL dogs have concurrent meniscal damage)
- Subchondral bone remodeling in response to abnormal forces
TPLO corrects the mechanical instability, but the cartilage damage already present does not reverse.
The joint has a permanently altered surface that is more susceptible to progressive OA than an intact, never-injured stifle.
Surgical trauma from the TPLO procedure itself also contributes.
The operation creates local inflammation that can accelerate cartilage breakdown in the first months, even as it creates the long-term stability that slows OA over years.
What research shows about OA progression after TPLO
Rate of progression
A prospective radiographic study (Rayward et al., 40 dogs, JSAP) found a significant increase in mean osteophyte score between the preoperative assessment and 6-month post-surgical examination.
However, in the majority of dogs in this study, there was no further radiographic progression of osteophytosis during the study period.
A larger long-term study (94 TPLO dogs, 133 stifles, followed to 3+ years) found OA progressed more after TTA (p=0.003) and in dogs with bilateral stifle surgery (p=0.022).
Dogs treated with TPLO had less pain and fewer mobility issues than TTA dogs at long-term follow-up, including better scores for stiffness, limping, jumping, climbing, and quality of life.
Functional outcomes vs. radiographic findings
Radiographic OA does not always correlate directly with clinical signs. Many dogs have significant osteophyte formation on radiographs but remain comfortable and functional with appropriate management.
Conversely, some dogs with relatively mild radiographic changes show significant clinical signs.
Early signs of arthritis after TPLO
Signs typically appear gradually rather than acutely. Watch for:
Morning stiffness: reluctance to get up or moving stiffly for the first few minutes after resting, improving with gentle activity.
Reduced activity: decreased willingness to run, jump, climb stairs, or sustain exercise at previous levels.
Lameness after exercise: the dog is comfortable on a short leash walk but noticeably lame after a longer walk or play session.
Behavioral changes: irritability, reluctance to be touched on the operated limb, reduced interaction with family members.
Muscle loss: loss of thigh muscle mass on the operated limb as the dog offloads it.
Joint swelling: persistent low-grade swelling around the stifle due to chronic synovial inflammation.
Long-term management of post-TPLO arthritis
Weight management
The most impactful single intervention. Every pound of excess body weight multiplies the compressive force on the stifle joint with each step.
Dogs at ideal body condition score 4 to 5 out of 9 consistently have better long-term joint outcomes than overweight dogs.
Controlled, low-impact exercise
Regular, low-impact exercise maintains muscle mass, supports joint fluid circulation, and prevents joint stiffness. Leash walks on flat terrain, swimming, and underwater treadmill work are ideal.
High-impact activities ball chasing, jumping, sustained running accelerate cartilage wear.
Joint supplements
Glucosamine and chondroitin sulfate support cartilage health and reduce inflammation. Omega-3 fatty acids (EPA and DHA) have anti-inflammatory properties with evidence for benefit in canine OA.
These are maintenance-level interventions appropriate for all post-TPLO dogs as lifelong support.
NSAIDs
Non-steroidal anti-inflammatory drugs (meloxicam, carprofen, grapiprant) are the most effective pharmaceutical interventions for OA pain.
They are used on a needs basis for dogs with intermittent discomfort, or continuously for dogs with chronic significant OA pain.
Kidney and liver function monitoring is required for dogs on long-term NSAID therapy.
Disease-modifying osteoarthritis agents
Librela (bedinvetmab), an anti-nerve growth factor monoclonal antibody approved for canine OA pain, is a newer option for dogs that do not respond adequately to NSAIDs or cannot tolerate them.
Discuss with your veterinarian if your dog's arthritis is not well-controlled with standard approaches.
Physical rehabilitation
Certified canine rehabilitation practitioners can provide individualized programs combining therapeutic exercises, hydrotherapy, laser therapy, and acupuncture to maintain muscle mass, joint mobility, and overall comfort.

Frequently asked questions
Does every dog get arthritis after TPLO?
Yes. All dogs that rupture a CCL develop some degree of OA in that stifle the process begins at the time of ligament injury and is not fully stopped by surgery.
TPLO significantly slows the rate of progression compared to no treatment or less effective surgeries, but it does not prevent OA entirely.
How quickly does arthritis progress after TPLO?
Research shows a significant increase in radiographic OA scores at 6 months post-TPLO, then a more gradual increase over the following 24 to 36 months.
In many dogs, radiographic progression stabilizes after 2 to 3 years. Clinical signs depend on individual pain tolerance and concurrent management.
Can I see signs of arthritis before X-rays show it?
Yes. Dogs show clinical signs (stiffness, reduced activity, gait changes) often before radiographic changes are apparent.
This is why monitoring behavior and function not just waiting for X-ray evidence is important for timely intervention.
Is arthritis the same as TPLO failure?
No. Arthritis progression is expected and does not constitute surgical failure. TPLO failure refers to mechanical problems implant complications, non-union, persistent instability.
OA progression is a separate, expected degenerative process that is managed over the dog's lifetime.
What is the single best thing I can do to slow arthritis after TPLO?
Maintain your dog at an ideal lean body weight.
This single factor has the greatest impact on the rate of cartilage wear, joint inflammation, and long-term comfort of any intervention within owner control.

How Long Does Swelling Last After TPLO Surgery
Post-surgical swelling after TPLO is normal, expected, and self-limiting when managed correctly. Most incision-area swelling peaks within the first 2 to 5 days and resolves by 2 weeks.
Swelling that does not follow this trajectory -- that is not declining, or that appears new after initial improvement -- is the key indicator that requires veterinary attention.
Quick answer: Normal TPLO swelling peaks at days 2 to 5 and resolves within 1 to 2 weeks with cold therapy and rest. Ankle swelling from gravity-dependent fluid migration appears at days 3 to 5. Swelling increasing after day 5, or with warmth, redness, or discharge, warrants veterinary evaluation.
Key takeaways
- Normal TPLO swelling peaks at days 2 to 5: SustainableVet.org confirms mild incision swelling usually goes away within two weeks
- Ankle swelling is a normal gravity-dependent phenomenon: TPLO Info confirms ankle swelling typically appears at days 3 to 5; it is fluid migrating downward from the surgical site
- Cold therapy in the first 48 to 72 hours is the primary management tool: 10 to 15 minutes, 3 to 4 times daily, reduces swelling and pain
- Swelling worsening after day 5 or accompanied by warmth, redness, or discharge indicates infection, seroma, or hematoma; contact your vet within 24 hours
- Mild swelling can persist for weeks at a low level in larger dogs and those with poor activity restriction compliance; trajectory matters more than absolute level
- Nighttime swelling is common and normal: dogs move less at rest, allowing fluid to settle; this should improve by morning or after repositioning
Normal swelling: timeline and characteristics
Days 1 to 3: acute post-surgical swelling
Swelling begins within hours of surgery and results from:
- Surgical tissue trauma (incision through skin, subcutaneous tissue, and fascia)
- Bone cutting at the osteotomy site
- Inflammatory response to the metal plate and screws
- Fluid accumulating in the disrupted tissue spaces
This early swelling is diffuse, soft, and warm to the touch. It is the expected cellular response to surgery.
Days 2 to 5: peak swelling
Swelling typically peaks between days 2 and 5. The dog's leg may look noticeably larger at this stage, and some extension of swelling down the lower leg toward the ankle is normal.
Vetplayas confirms: swelling typically peaks within the first few days after surgery but should gradually subside over time.
Days 3 to 5: ankle swelling appears
A distinct swelling often appears at the ankle (tarsus) between days 3 and 5, sometimes alarming owners who notice it away from the surgical site. This is entirely normal.
TPLO Info confirms: it is completely normal for swelling to develop around the ankle approximately 3 to 5 days following surgery on the TPLO leg.
This swelling can be massaged and iced if it occurs and will resolve over a few days.
TPLO Austin confirms this finding identically. The mechanism is gravity-dependent migration of tissue fluid from the surgical site through the fascial planes of the lower leg.
Days 5 to 14: progressive resolution
From day 5 onward, swelling should consistently decrease with each daily inspection. Cold therapy, rest, and anti-inflammatory medication all contribute to this resolution.
SustainableVet.org confirms: mild swelling around the incision site usually goes away within two weeks. The trajectory must be consistently improving.
Beyond 2 weeks: residual low-level swelling
Some dogs retain mild soft swelling around the lower leg beyond 2 weeks, particularly larger dogs with greater tissue volume and dogs who have been less compliant with activity restriction.
This is usually minor and does not indicate a problem if:
- The swelling is soft and not warm
- There is no discharge or redness
- The dog is bearing weight and improving in lameness
Cold therapy: the primary management tool
Cold therapy is the evidence-based first-line intervention for post-surgical swelling.
Protocol:
- Wrap an ice pack or bag of frozen peas in a thin cloth or towel
- Apply to the incision and plate site for 10 to 15 minutes
- Repeat 3 to 4 times daily
- Begin on day 1 post-surgery
- Continue for the first 48 to 72 hours (the acute inflammatory phase)
SustainableVet.org confirms: cold therapy, like applying an ice pack wrapped in a towel for 10 to 15 minutes several times a day during the first 72 hours, helps reduce inflammation.
After the initial period, warm compresses can be used to promote circulation.
Never apply ice directly to the skin or incision -- frostbite and wound damage can result. Remove the pack immediately if the skin appears pale or very cold.
For the ankle specifically, TPLO Info confirms: ankle swelling can be massaged and iced. Gentle proximal-to-distal massage (toward the toes) applied after icing helps lymphatic drainage.
Concerning swelling: signs requiring veterinary contact
Swelling that is not declining after day 5
Normal swelling is consistently declining from day 5 onward. Swelling that is the same or larger than on day 3, measured at day 7, is not normal.
New swelling after apparent resolution
If swelling had reduced and then reappears -- particularly at the plate site rather than the incision -- this suggests a developing seroma, hematoma, or early infection.
SustainableVet.org confirms: you should be concerned if swelling increases after the first week or is accompanied by heat, redness, oozing, or a bad odor.
Warmth, firmness, redness, or discharge alongside swelling
These features distinguish infection from normal surgical edema. Normal edema is diffuse, soft, not dramatically warm, and has no discharge. Infection produces focal warmth, firmness, redness spreading beyond the incision, and discharge.
Swelling at the plate site (not the incision) weeks after surgery
This can indicate an implant-associated infection with seroma or early osteomyelitis. Requires radiographic assessment and deep sampling.
Seroma: a specific type of post-surgical swelling
A seroma is a localized collection of clear serous fluid under the skin, forming when tissue spaces fill with tissue fluid that has not been reabsorbed.
Seromas after TPLO are common and are distinct from infection.
Signs of seroma:
- A soft, fluctuant (fluid-filled) swelling at or near the incision
- Typically appears 1 to 3 weeks post-surgery
- Fluid is clear or pale yellow when aspirated
- No warmth, redness, or discharge from the incision itself
Most seromas resolve without treatment. Your vet will assess whether aspiration or monitoring is appropriate.

For the infection signs guide, see TPLO plate infection signs and treatment. For the bruising guide, see bruising after TPLO surgery in dogs.
Frequently asked questions
Is it normal for the whole leg to swell after TPLO?
Yes, in the early days. Diffuse swelling of the lower leg, extending from the surgical site toward the ankle, is normal in the first 1 to 2 weeks.
Gravity and the inflammatory response both contribute. This resolves as the inflammatory process settles and the dog begins controlled weight bearing.
My dog's leg looks huge at day 3. Is that too much?
Day 3 is within the normal peak swelling period.
Unless the swelling is dramatically asymmetric compared to the other leg, is very hot, or is producing discharge, observe and continue cold therapy as directed.
If you are concerned, contact your vet to describe the swelling -- they can advise whether in-person assessment is needed.
Should I massage the swollen leg?
Gentle lymphatic massage (soft strokes toward the body, from the ankle upward) after icing can help reduce distal swelling.
Do not massage directly over the incision or plate site, and do not massage aggressively. Ask your vet or rehabilitation therapist to demonstrate the correct technique.
My dog's swelling is going up and down -- bigger in the evening, smaller in the morning. Is that normal?
Yes. SustainableVet.org confirms that mild nighttime swelling occurs because dogs move less while resting, allowing fluid to settle. Morning improvement after repositioning and movement is normal.
The concern is when the morning maximum is larger than the previous day's morning maximum -- a consistently worsening trend.
When does warm therapy replace cold therapy?
Cold therapy is most beneficial in the first 48 to 72 hours (the acute inflammatory phase). After 72 hours, warm compresses promote circulation and may help reabsorb residual fluid.
The transition is typically around days 3 to 5. Never apply warmth to an incision that looks infected or discharging -- this can worsen infection.

Arthrex TPLO Weight Chart Explained
After TPLO surgery, one of the most important questions owners and rehabilitation teams ask is: how much weight should my dog be putting on the operated leg right now?
The Arthrex TPLO weight chart provides a structured, week-by-week answer to that question, giving both surgeons and owners a shared reference point for tracking recovery progress.
Quick answer: The Arthrex TPLO weight chart tracks the percentage of body weight a dog bears on the operated leg at each recovery stage — from 0 to 10% in the first weeks to 100% by 8 to 12 weeks post-surgery.
Key takeaways
- The weight chart tracks weight-bearing percentage at each stage, from 0 to 10% in weeks 1 to 2 to 100% by weeks 8 to 12
- It is a rehabilitation monitoring tool, not a surgical planning tool: the rotation chart governs intraoperative correction; this tracks recovery
- Progression must be gradual: advancing too fast risks implant failure; too slow leads to atrophy and stiffness
- The chart integrates with clinical examination: 8-week radiographs, gait assessment, and muscle mass evaluation are considered alongside chart milestones
- Individual dogs vary: the chart provides population-level benchmarks; your surgeon's instructions take precedence
- The chart is used alongside the plate size and rotation charts: together they form the Arthrex TPLO system framework
What the weight chart is and what it is not
The Arthrex TPLO weight chart is a post-operative rehabilitation tool.
It shows recommended weight-bearing percentages at specific time points after surgery a reference guide that helps veterinarians, rehabilitation therapists, and owners track whether a dog's recovery is progressing appropriately.
It is not the same as the rotation chart (which guides intraoperative tibial rotation) or the plate size chart (which guides implant selection before surgery).
These three charts together form the Arthrex TPLO planning and monitoring system.
For the rotation chart guide, see Arthrex TPLO rotation chart explained. For the plate overview, see Arthrex TPLO plate overview and use.
Understanding the weight-bearing percentages
The chart uses percentage of body weight as its unit of measurement.
This is a more useful measure than time alone because it relates directly to the mechanical load placed on the healing osteotomy and implant.
0 to 10% weight-bearing (weeks 1 to 2): toe-touching and minimal contact only. The dog is not actively loading the leg during this phase. Bathroom trips on leash are permitted, but no sustained weight-bearing.
10 to 30% (weeks 2 to 4): the dog begins placing meaningful weight on the leg during slow leash walks. This corresponds to the short 5 to 10 minute leash walks prescribed at this stage. The healing osteotomy is starting to consolidate but is not yet ready for full load.
30 to 60% (weeks 4 to 8): progressive loading during longer walks, sit-to-stand exercises, and early rehabilitation activities. Most dogs are visibly improving in gait symmetry during this phase.
60 to 100% (weeks 8 to 12): full weight-bearing is approached and typically achieved after the radiographic recheck at week 8 confirms adequate osteotomy healing. Activity levels increase under veterinary guidance.
How to use the chart in practice
As a clinical benchmark
Surgeons use the weight chart to assess whether a dog is progressing as expected at each recheck visit.
A dog that is well below the expected weight-bearing percentage for their stage may have inadequate pain control, implant complications, or infection.
A dog exceeding the expected percentage may be at risk of mechanical overload if the bone has not yet consolidated enough to tolerate the load.
As an owner reference
Owners are not expected to measure exact weight-bearing percentages at home this requires force plate analysis or pressure-sensitive walkway equipment.
The chart provides a conceptual framework: early recovery shows only toe-touching; by weeks 4 to 6, the dog places meaningful weight during walks; by weeks 10 to 12, gait symmetry improves steadily.
What affects weight-bearing progress
Bone healing rate: younger dogs and smaller breeds typically consolidate the osteotomy faster than older or giant breed dogs.
Pain control: inadequate analgesia is the most common cause of delayed weight-bearing. A dog in pain will protect the operated leg regardless of how well the surgery went. Contact your surgeon if your dog is significantly below expected weight-bearing benchmarks.
Muscle atrophy: dogs that enter surgery with significant muscle atrophy from prolonged pre-surgical lameness progress more slowly and benefit most from structured rehabilitation.
Body weight: heavier dogs place more absolute load on the healing osteotomy at any given percentage. This is one reason weight management is emphasized throughout the TPLO recovery period.
Rehabilitation: dogs receiving structured rehabilitation (PROM, sit-to-stand, hydrotherapy) consistently achieve better weight-bearing progression than those managed with rest alone.
When the chart says one thing and your dog does another
The weight chart represents population-level expectations. Individual dogs routinely deviate from the expected timeline for reasons that are often identifiable and manageable.
If your dog is significantly under-progressing: contact your surgeon to rule out infection, implant problems, or inadequate pain management before assuming slow healing.
If your dog appears to be weight-bearing well ahead of schedule: this does not mean the osteotomy is healed faster than expected.
Radiographic confirmation at week 8 is still required regardless of how the dog looks clinically. Apparent early function does not mean the bone has consolidated enough to withstand full unrestricted activity.
For the full weight-bearing recovery timeline guide, see how soon can a dog walk after TPLO surgery.

Frequently asked questions
Is the Arthrex TPLO weight chart the same as a standard recovery timeline?
Not exactly. A recovery timeline tells you what activities to do and avoid at each stage.
The weight chart specifically tracks how much weight the dog is placing on the operated leg at each stage, expressed as a percentage of body weight.
The two are related but provide different information.
Can I measure my dog's weight-bearing at home?
Not precisely. Force plate and pressure-sensitive walkway systems that measure actual weight distribution require specialist veterinary equipment.
At home, you can observe whether the dog is toe-touching, placing the foot flat, and walking with increasing symmetry which approximates the chart's progression categories without exact percentages.
What if my dog refuses to use the leg at all two weeks after TPLO?
Non-weight-bearing at two weeks is a warning sign. TPLO Austin confirms that if your pet is not bearing weight within two weeks of surgery, contact your veterinarian.
The most common causes are inadequate pain control, infection, or implant positioning concerns all of which are addressable if caught early.
Do all TPLO surgeons use the Arthrex weight chart?
No. The Arthrex system is one of the two major TPLO implant systems in the US (alongside Synthes). Surgeons using Synthes implants use Synthes-specific planning tools.
Some surgeons use individualized rehabilitation protocols rather than system-specific charts. The underlying recovery milestones are similar regardless of which chart or system is used.
What happens at the 8-week recheck in terms of weight-bearing?
At the 8-week recheck, radiographs assess osteotomy healing. If healing is adequate, the surgeon approves increased activity typically 20 to 30 minute leash walks and the beginning of return-to-normal activity.
The weight chart at this point expects the dog to be approaching or achieving 100% weight-bearing on the operated leg.

Long-Term Outcomes of TPLO Surgery
TPLO produces excellent long-term outcomes for most dogs with CCL rupture.
The published evidence covers follow-up periods from 1 year to 6.8 years post-surgery and consistently shows high rates of functional recovery alongside moderate but ongoing arthritis progression.
Understanding what the data shows helps owners set realistic expectations about what TPLO achieves and what ongoing management is required.
Quick answer: Published long-term TPLO outcomes: 90 to 95% of dogs regain complete or near-complete limb function; good to excellent results in 90.4% of patients at up to 6.8 years; 93% owner satisfaction at 12 months (RCVS). Arthritis progresses moderately in all CCL-affected stifles but TPLO produces less progression than TTA.
Key takeaways
- 90 to 95% of dogs regain complete or near-complete limb function: RCVS Canine Cruciate Registry confirms this range; 93% owner satisfaction at 12 months
- Good to excellent results in 90.4% of patients up to 6.8 years post-surgery: TPLO Info cites this long-term retrospective study, one of the longest published TPLO follow-up datasets
- Arthritis progresses in all CCL-affected joints regardless of surgical technique: TPLO slows progression compared to TTA and lateral suture but does not stop it
- TPLO produces better long-term outcomes than TTA in comparative studies: OA progressed more after TTA; TPLO dogs had less pain, better walking, less morning stiffness, and better quality of life at 3+ years per the 94-dog study
- TPLO produces better owner satisfaction than lateral suture: 93% vs. 75% for lateral fabellar suture per TPLO Info; kinematic gait analysis also favored TPLO
- Meniscal management at the time of TPLO affects long-term outcomes: dogs with partial meniscectomy had higher rates of excellent long-term results and less OA progression per TPLO Info
Functional outcomes: what the data shows
At 1 year post-surgery
A 2013 comparative study of TPLO vs. TTA found TPLO patients achieved 93% restoration of limb function at 1 year, as assessed by objective force plate analysis.
This is the most frequently cited 1-year outcome figure.
RCVS Canine Cruciate Registry confirms: 90 to 95% of dogs regain complete or near-complete function; 93% of owners report satisfaction at 12 months.
At 2 years post-surgery
A PMC long-term functional outcome study found that most dogs with CCL repair -- regardless of technique -- showed improvement in limb function at 2 years compared to pre-operative status.
Objective gait analysis at 2 years showed that the operated leg approached the contralateral leg in force plate measurements.
At 3+ years post-surgery
The comparative TPLO vs. TTA study with follow-up at 3+ years provides the clearest long-term comparative data:
- OA progressed more in TTA than in TPLO dogs
- TPLO dogs scored better on the Canine Brief Pain Inventory across all domains (average pain, walking interference, morning stiffness, jumping, climbing)
- TPLO dogs scored better on the Canine Orthopedic Index (quality of life)
- The study concluded TPLO provides better long-term radiographic and functional outcome than TTA
At up to 6.8 years post-surgery
TPLO Info cites a long-term retrospective study with follow-up extending to 6.8 years: good to excellent results were obtained in 90.4% of patients at this timeframe.
This is the longest published follow-up in a TPLO outcome dataset and confirms that the 90%+ functional recovery rate is durable over years rather than only at 12 months.
Arthritis: the universal long-term consideration
All dogs with CCL disease develop progressive osteoarthritis in the affected stifle. This is true regardless of whether surgical or conservative management is chosen.
TPLO reduces the rate of arthritis progression and the severity of clinical signs compared to lateral suture stabilization and TTA, but arthritis progression continues.
TPLO Info confirms: in the long term, there was a moderate but significant progression of OA following TPLO.
SustainableVet.org confirms: while TPLO stabilizes the knee and slows down arthritis progression, it does not completely eliminate the risk; mild arthritis is expected, even in successful cases.
Managing long-term arthritis after TPLO
Weight management: every additional kilogram of body weight increases stifle joint loading. Maintaining lean body condition is the single most impactful owner-controlled variable for arthritis management.
Joint supplements: glucosamine, chondroitin, and omega-3 fatty acids (fish oil) are commonly recommended and have evidence supporting modest benefit for joint health and comfort.
Low-impact exercise: regular, controlled exercise (walking, swimming, hydrotherapy) maintains muscle mass and joint lubrication without the impact forces of running and jumping. Consistent low-impact exercise is more beneficial than sporadic high-intensity sessions.
NSAIDs for flares: carprofen, meloxicam, or other veterinary NSAIDs are used for periods of increased arthritis pain. Long-term NSAID use requires periodic monitoring of renal and hepatic function.
Rehabilitation: an ongoing physiotherapy relationship with a certified canine rehabilitation practitioner helps maintain muscle mass and joint mobility as the dog ages.
Factors that affect long-term outcomes
Age at surgery: younger dogs typically achieve better long-term function than older dogs. Older dogs heal more slowly and have a higher baseline level of arthritis-related joint change before surgery.
Body weight: heavier dogs show more arthritis progression and more persistent lameness than lighter dogs at equivalent follow-up periods.
Meniscal management: TPLO Info confirms partial meniscectomy (when a meniscal tear is present) is associated with significantly higher rates of excellent long-term results and less OA progression compared to meniscal release or leaving the meniscus intact when abnormal.
Surgical timing: earlier intervention (before severe arthritis develops) produces better long-term outcomes. Dogs treated early in the disease process have less existing joint damage at the time of surgery.
Rehabilitation compliance: dogs that complete structured rehabilitation programs and achieve good muscle mass restoration have better long-term function than those managed with restricted activity alone.
Bilateral CCL disease: TPLO Info confirms OA progresses more in dogs with bilateral stifle surgery than unilateral. This may reflect the more severe underlying degenerative process in these dogs.
TPLO vs. lateral suture: long-term comparison
TPLO Info confirms owner satisfaction of 93% for TPLO vs. 75% for lateral fabellar suture; kinematic gait analysis also favored TPLO outcomes.
This comparison is most relevant for medium-sized dogs where both procedures are technically appropriate. For large dogs over 35 to 40 kg, TPLO consistently outperforms lateral suture in long-term outcomes.
For small dogs under 15 kg, lateral suture achieves comparable results at substantially lower cost.
TPLO vs. TTA: long-term comparison
SustainableVet.org confirms: when comparing TTA to TPLO, research suggests similar long-term arthritis outcomes in some studies, but TPLO patients usually recover faster and regain function sooner.
The 3+ year follow-up comparative study is the most comprehensive published comparison and clearly favors TPLO in both OA progression and functional/quality-of-life outcomes.

Frequently asked questions
Will my dog be completely normal after TPLO?
Most dogs return to their pre-injury activity level after full recovery.
RCVS and multiple studies confirm 90 to 95% regain complete or near-complete function.
"Completely normal" is achievable for most dogs, with the caveat that some mild arthritis develops over time in virtually all cases.
Dogs may show stiffness on cold days or after long rest periods as they age.
Does TPLO stop arthritis?
No -- it reduces and slows arthritis progression compared to conservative management and other surgical techniques, but does not stop it. All CCL-affected stifles develop progressive OA.
The goal of TPLO is to stabilize the joint and minimize the rate of arthritis development, not eliminate it.
How long does the TPLO plate last?
The plate is designed to be permanent.
Good to excellent results at 6.8 years (the longest published TPLO follow-up) with the plate in place demonstrates the durability of the implant in the overwhelming majority of cases.
Plate complications requiring removal occur in 3.5 to 7.5% of cases.
Is my dog at risk for the CCL on the other side?
Yes. RCVS confirms approximately 50% of dogs will develop CCL disease in the other hind limb.
This is not a consequence of TPLO -- it reflects the degenerative nature of CCL disease that typically affects both stifles. Monitoring the contralateral stifle is appropriate in all TPLO dogs.
Does the long-term outcome depend on the surgeon's experience?
Yes, to some degree. Surgeons with more TPLO experience have lower complication rates (including SSI and delayed union), and complications are associated with worse long-term outcomes.
Using a board-certified surgeon or an experienced general practitioner with dedicated TPLO training reduces risk. The published SSI studies confirm surgeon experience as an independent risk factor for post-TPLO complications.

Why Is My Dog's Leg Clicking After TPLO Surgery?
A clicking or popping sound from the stifle after TPLO surgery is a common observation that owners report, especially during the first weeks of recovery.
It is not automatically a sign of a problem.
The clinical significance depends on what accompanies the click: is the dog bearing weight and recovering normally, or is clicking associated with lameness, pain, or a trajectory reversal?
Quick answer: Post-TPLO clicking most often reflects normal joint adjustment, soft tissue movement, or cavitation. The most clinically important cause is a meniscal tear, producing a meniscal click with pain and returning lameness. Clicking without lameness or pain in early recovery is usually benign.
Key takeaways
- Most post-TPLO clicking is benign: the click typically comes from joint adjustment to new mechanics; the dog usually feels fine even when a sound is present
- The meniscal click is the clinically significant type: dogs with meniscal tears exhibit a meniscal click accompanied by lameness and pain
- Clicking with lameness or pain warrants prompt veterinary evaluation: clicking with swelling, limping, or avoiding the leg could signal instability, implant issues, or a torn meniscus
- Clicking that is isolated, early in recovery, and not associated with lameness is usually normal and improves as healing progresses
- Late-onset clicking in a previously normal recovery is more concerning than early clicking; it suggests a new event such as meniscal tear or implant loosening
- Implant loosening is a rare but serious cause of clicking: abnormal joint mechanics from loosened screws or plate produce clicking accompanied by pain and radiographic changes
What causes clicking after TPLO surgery
Normal joint adjustment
After TPLO, the tibial plateau is repositioned to a new angle. The soft tissues, tendons, and joint capsule require weeks to adapt to this new geometry.
During this adaptation period, movement can produce audible sounds as structures slide over each other or snap slightly over new contours.
TPLO Info confirms: after CCL repair, the joints adjust to new motion. The click comes from the knees. The dog usually feels fine even when a sound is present.
Soft tissue movement over the implant
The TPLO plate sits against the medial tibial surface. Tendons and fascial layers that previously moved over the normal tibial contour now move over a plate with a different profile.
This can produce audible snapping or clicking sounds during flexion and extension, particularly in the first weeks before soft tissue accommodation occurs.
Gas bubble release (cavitation)
Joint capsule distension from post-surgical effusion can trap gas in the joint space. Movement releases this gas in small pops -- the same mechanism as knuckle cracking in humans.
This is painless and harmless.
Meniscal click (most significant cause)
The medial meniscus is vulnerable to injury in CCL disease. At the time of TPLO, the surgeon assesses the meniscus and removes damaged tissue.
However, meniscal injury can occur after TPLO -- either from previously undetected damage that progresses, or from new injury in a joint that has not yet fully stabilized.
Laguna Woods Vets confirms: dogs with meniscal tears frequently exhibit a meniscal click. If damage is noted during TPLO, the meniscus is removed. If not removed, it may tear later.
SustainableVet.org confirms: symptoms of meniscal damage include clicking when the dog moves, lameness, reluctance to use the affected leg, and discomfort when bending the knee.
The meniscal click is distinguished from benign clicking by:
- Accompanying lameness (often a sudden return of limping after initial improvement)
- Pain when the stifle is manipulated on examination
- Worsening trajectory rather than improvement
Implant-related clicking (uncommon)
Plate or screw loosening generates abnormal tibial motion during weight bearing, which can produce clicking.
This is uncommon in an uncomplicated TPLO but more likely if the dog has been overactive during recovery.
Signs include pain localized to the plate site and radiographic evidence of implant migration or peri-implant bone changes.
SustainableVet.org confirms: implant failure is rare but serious; plates or screws can loosen or break if the dog is too active early, leading to discomfort and joint noises.
Normal vs. concerning clicking: a practical guide
Likely normal (benign):
- Clicking present from the first days after surgery
- No lameness associated with the click
- Dog is bearing weight and improving week by week
- Click is quiet and intermittent
- Dog does not react (wince, pull back, vocalize) when the stifle is manipulated
Warrants veterinary evaluation:
- Clicking that appears new after a period of recovery without clicking
- Clicking accompanied by lameness or reluctance to bear weight
- Dog flinches or vocalizes when the stifle is flexed
- Clicking that is getting louder or more frequent over time
- Lameness that had been improving and then reverses
SustainableVet.org confirms: contact your vet if the clicking sound is persistent or getting worse over time; a mild clicking early in recovery is normal but it should improve as healing progresses.
Meniscal tear after TPLO: what happens next
If a meniscal tear is suspected or confirmed, management depends on severity.
Mild cases: pain management with NSAIDs, joint supplements, and controlled exercise restriction. The meniscus may stabilize with conservative management if the tear is small and the joint is otherwise stable.
Cases with ongoing pain or lameness: partial meniscectomy (surgical removal of the torn portion of the meniscus) is required. This is a second surgical procedure requiring general anesthesia and a repeat recovery period.
SustainableVet.org confirms: if a meniscal tear causes ongoing pain and instability, surgery is often needed; this may involve a partial meniscectomy.
Larger dogs and clicking
Larger dogs are more likely to produce audible joint sounds during recovery. Greater body mass means greater joint loading forces, which amplify soft tissue and implant movement sounds.
SustainableVet.org confirms: larger dogs are more likely to make joint sounds during recovery; their extra weight puts more pressure on the healing leg, which can make clicking more noticeable.
This does not mean clicking in large dogs is more likely to be pathological -- only that it is more audible when it occurs.
When to contact your vet about clicking
Contact your vet promptly (same day or within 24 hours) if:
- Clicking is accompanied by lameness or non-weight bearing
- A dog that was improving begins to worsen (trajectory reversal)
- The click is producing a visible pain response
- The click appears late in recovery (after weeks of silent healing)
Contact at your next scheduled appointment (can wait):
- Intermittent clicking early in recovery without lameness
- Click that is quieter week by week
- Dog is bearing full weight and improving in function

For the lameness guide, see lameness after TPLO surgery in dogs. For the leg shaking guide, see dog leg shaking after TPLO surgery.
Frequently asked questions
My dog's knee has been clicking for 3 weeks but she is not limping at all. Should I be worried?
Three weeks of clicking with no lameness and a normal, improving recovery trajectory is most likely benign joint adjustment. Monitor for lameness, pain on stifle palpation, or worsening of the click.
Mention it at your next scheduled vet appointment -- this is not an emergency call.
My dog's leg clicked once loudly while getting up, and then she held the leg up. What do I do?
Contact your vet the same day. A sudden loud click followed by acute lameness may indicate a meniscal injury event. This presentation warrants veterinary examination and likely radiographs.
Can clicking after TPLO get better on its own?
Yes -- benign mechanical clicking from joint adjustment and soft tissue accommodation typically resolves or reduces significantly over the first 4 to 8 weeks.
A meniscal click does not resolve without treatment of the meniscal tear.
Does clicking mean the plate is failing?
Not typically. Implant failure clicking is accompanied by pain and worsening lameness. Benign clicking in a comfortable, normally-recovering dog does not indicate implant failure.
Radiographs at the scheduled 6-week and 12-week appointments assess implant integrity.
My dog clicks on every step. Is that different from occasional clicking?
Consistent clicking on every step, particularly if it has a regular, reproducible pattern during weight bearing, is more likely to have a structural cause (meniscal click) than intermittent clicking.
Mention this to your vet and assess whether lameness is present.

Ankle Swelling After TPLO Surgery in Dogs
Many owners are surprised to find their dog's ankle swollen after TPLO surgery especially when the surgery was performed on the knee, which is well above the ankle.
This gravity-dependent swelling is one of the most common post-TPLO findings, and in most cases it is a completely normal part of recovery.
Knowing what causes it, when it is expected, and when it becomes a reason to call your vet puts you in a much better position during recovery.
Quick answer: Ankle swelling 3 to 5 days post-TPLO is normal — gravity pools post-surgical fluid at the ankle. Resolves in 1 to 2 weeks with rest and cold packing. Call your vet if swelling is hot, fast-growing, or discharging.
Key takeaways
- Ankle swelling at 3 to 5 days post-TPLO is normal: fluid from the knee surgical site tracks down the leg; TPLO Info confirms this is routine
- Gravity pulls fluid to the ankle: dogs do not elevate the leg during recovery, so post-surgical fluid migrates downward
- Normal ankle swelling is mild, soft, and non-painful: not hot, red, rapidly growing, or producing any discharge
- Cold packing and gentle massage help resolve ankle swelling: they reduce inflammation and encourage fluid movement
- Excessive activity worsens ankle swelling: running, jumping, or sustained weight-bearing beyond short leash walks increases fluid accumulation
- Infection is the main abnormal cause: infected swelling is warm, painful, and accompanied by fever or lethargy
Why does ankle swelling happen after TPLO?
TPLO surgery is performed at the proximal tibia just below the knee. However, the inflammatory response and fluid production that result from surgery are not confined to the exact surgical site.
Gravity-dependent fluid migration: post-surgical serum and inflammatory fluid produced at the knee level migrate downward along tissue planes. Because dogs do not elevate their legs during recovery unlike a human keeping a leg raised on a pillow this fluid pools in the lower leg and ankle region.
TPLO Info confirms ankle swelling at 3 to 5 days post-TPLO is completely normal and recommends massage and icing if this occurs.
Lymphatic disruption: the surgery disrupts local lymphatic vessels that normally drain fluid from the lower leg. Until these pathways regenerate or compensate, fluid accumulation in the lower leg is common.
Reduced movement: when a dog is resting with the leg dependent (hanging down), fluid accumulates. Brief controlled leash walks stimulate the lymphatic pump and muscle contractions that help move fluid back up the leg.
Normal ankle swelling: what to expect
Normal post-TPLO ankle swelling typically:
- Appears at day 3 to 5 post-surgery
- Is soft and pitting (you can press on it and it indents temporarily)
- Is not warm to the touch
- Does not produce any discharge
- Does not cause significant additional pain beyond the expected post-operative discomfort
- Gradually reduces over 1 to 2 weeks with rest and activity restriction
VCA Animal Hospitals notes that mild to moderate swelling is expected after TPLO surgery as the body responds to tissue trauma and the healing process begins.
Abnormal ankle swelling: warning signs
Contact your veterinarian if you observe:
- Swelling that is rapidly increasing especially in the first 1 to 2 weeks
- Warmth or heat in the swollen area beyond mild
- Redness or skin discoloration around the ankle or lower leg
- Discharge or pus from the surgical incision or surrounding skin
- Your dog refusing to bear any weight on the leg
- Fever, lethargy, or loss of appetite alongside the swelling
- Swelling that is growing rather than shrinking after the first week
These signs suggest infection, hematoma, or a complication beyond normal gravity-dependent fluid pooling.
How to manage ankle swelling at home
Cold packing: apply a cold pack (frozen peas wrapped in a thin towel) to the ankle for 10 to 15 minutes, 2 to 3 times daily. Cold reduces local inflammation and provides mild pain relief. Always wrap the cold pack never apply ice directly to skin.
Gentle massage: TPLO Info recommends gentle massage if ankle swelling develops. Using a light hand, massage from the ankle upward toward the knee to encourage fluid to move back toward the body. Do not massage the surgical incision site itself.
Activity restriction: the most important intervention. Every unnecessary step the dog takes increases fluid production and worsens swelling. Strict confinement with leash-only bathroom walks is essential for the first 6 to 8 weeks.
Short controlled leash walks: paradoxically, very short leash walks (5 to 10 minutes) are better than complete immobility. Gentle controlled movement stimulates the lymphatic pump and helps clear fluid more effectively than prolonged rest. Do not allow the dog to run, jump, or play.
Timeline: when should ankle swelling resolve?
Most normal ankle swelling resolves within 1 to 2 weeks of surgery when activity restriction is maintained.
Vetplayas notes that swelling is a common response to surgical intervention and typically improves as healing progresses.
Persistent ankle swelling beyond 2 to 3 weeks, or swelling that worsens rather than improves, warrants a veterinary recheck.
This may indicate a seroma has formed in the lower leg, or that the dog is more active than recommended.

Frequently asked questions
Is ankle swelling after TPLO always from the surgery?
In the first 1 to 3 weeks post-surgery, yes ankle swelling almost always relates directly to the procedure.
Rarely, a dog might develop an unrelated issue (insect sting, foreign body, contact dermatitis) but the timing overwhelmingly points to post-surgical fluid migration in most cases.
Should I wrap my dog's ankle if it's swollen after TPLO?
Only if your vet specifically recommends it. Improper bandaging can cut off circulation or cause pressure sores.
If you are concerned about the ankle swelling, contact your vet before applying any bandage or wrap at home.
My dog's ankle is swollen but the knee looks fine. Is that normal?
Yes. The surgical site at the knee may look relatively normal while the ankle is more visibly swollen because gravity pulls fluid downward.
This pattern is completely consistent with normal post-TPLO fluid migration and is not a sign that something is wrong at the ankle itself.
Can I use a compression sock on my dog's ankle?
Not without veterinary guidance. Human compression garments are not designed for canine anatomy and can cause pressure injury, especially around the hock joint.
If compression is indicated, your vet will apply an appropriate veterinary bandage.
When should I take my dog back to the vet for ankle swelling?
If the swelling appears within the first 1 to 2 weeks and is mild, soft, and not causing distress monitor at home with cold packing and massage.
If it is growing, warm, accompanied by redness or discharge, or if your dog is in significant pain, contact your vet promptly rather than waiting for a scheduled recheck.

Common Myths About TPLO Surgery Explained
TPLO is the most commonly performed surgery for CCL rupture in dogs and the most commonly misunderstood.
Misconceptions about TPLO cause unnecessary hesitation, lead some owners to choose inferior alternatives, and create unrealistic expectations about recovery.
This guide addresses the 10 most common myths directly -- with evidence-based clarification for each.
Quick answer: The most persistent TPLO myths: that dogs can manage without surgery, that TPLO is only for large breeds, that recovery takes a few weeks, that the plate must be removed after healing, and that TPLO prevents arthritis. All are false. TPLO has a 90 to 95% success rate.
Key takeaways
- Myth: "My dog can heal without surgery": dog knee anatomy differs fundamentally from human; without surgery, severe OA, meniscal tearing, and chronic lameness are expected in most dogs over 15 kg
- Myth: "TPLO is only for large dogs": SustainableVet.org confirms TPLO is just as effective for small and toy breeds; the biomechanical correction is appropriate regardless of size
- Myth: "Recovery only takes a few weeks": bone healing takes 8 to 12 weeks; full muscle recovery takes 4 to 6 months; 8 to 12 weeks is the minimum restriction period
- Myth: "The plate needs to be removed after healing": the TPLO plate is designed to be permanent; removal is only performed when complications arise
- Myth: "TPLO prevents arthritis": all CCL-affected stifles develop progressive OA regardless of surgical technique; TPLO reduces OA progression but does not prevent it
- Myth: "Dogs are in severe pain after TPLO": SustainableVet.org confirms this is a misconception; modern multi-modal pain management controls post-surgical pain effectively
Myth 1: "My dog can heal without surgery"
The truth: dogs and humans have fundamentally different knee anatomy. In humans, the flat tibial plateau and strong surrounding musculature allow some CCL tears to be managed conservatively with physical therapy and bracing. In dogs, the tibial plateau slopes steeply downward, generating a cranial shear force that the absent CCL cannot resist. Without surgical correction of this force, the joint remains mechanically unstable with every weight-bearing step.
TPLO Info confirms: dogs and humans respond very differently to CCL tears. Without surgery, severe OA can develop, meniscal tearing can occur, and other side effects may be present.
Conservative management (strict rest, weight management, joint supplements, physical therapy) can provide temporary improvement, particularly in small dogs and partial tears.
For most dogs over 15 kg with complete CCL rupture, conservative management does not restore normal joint stability, and progressive lameness, OA, and joint deterioration are the expected outcome.
Who can be managed conservatively?
- Very small dogs (under 10 to 15 kg) with partial tears and low activity levels
- Dogs with significant comorbidities where anesthetic risk outweighs surgical benefit
- Owners who decline surgery after being fully informed of expected outcomes
For all other dogs -- medium and large breeds, young dogs, active dogs, complete ruptures -- surgery produces substantially better outcomes than conservative management.
Myth 2: "TPLO is only for large dogs"
The truth: TPLO was originally developed for large and giant breeds because they were the most severely affected by CCL disease and the most poorly served by lateral suture stabilization. But TPLO corrects the underlying biomechanical problem (excessive tibial plateau angle) in any dog, regardless of size.
SustainableVet.org confirms: TPLO was initially developed for large dogs due to biomechanical challenges, but has been found just as effective for small and toy breeds.
For small dogs, both TPLO and lateral suture stabilization can achieve good outcomes.
The decision for a small dog should be based on the dog's TPA, activity level, and individual assessment -- not a blanket assumption that TPLO is unnecessary.
Myth 3: "TPLO recovery only takes a few weeks"
The truth: bone healing takes 8 to 12 weeks. This is the period of activity restriction. But bone healing and functional recovery are not the same thing. Full muscle rebuilding and joint function restoration takes 4 to 6 months from surgery.
Canada Vet Express confirms: recovery is gradual; most dogs begin walking within a few days and return to normal activity within 3 to 4 months with proper care.
The 8 to 12 week bone healing timeline means:
- Activity restrictions are in place for 8 to 12 weeks minimum
- Radiographic confirmation of healing is required before restrictions are lifted
- Progressive return to full activity follows the radiographic clearance
After restrictions are lifted, the operated leg continues to rebuild strength and coordination for months. For sport dogs and working dogs, the return-to-sport protocol extends to 7 to 9 months from surgery.
Myth 4: "The TPLO plate needs to be removed after the bone heals"
The truth: the plate is designed to remain in place permanently. It does not need to be removed when the osteotomy heals. Routine plate removal is not standard practice in veterinary orthopedics.
SustainableVet.org confirms: these implants are meant to stay in place permanently, but in rare cases they can cause problems; removal is only performed when complications arise.
When plate removal is performed:
- Deep implant-associated infection requiring source removal
- Implant failure (breakage, loosening causing instability)
- Persistent implant irritation producing clinical lameness specifically attributable to the plate
In the vast majority of dogs, the plate is never removed. It remains in place for life with no adverse effects.
Myth 5: "TPLO prevents arthritis"
The truth: TPLO reduces and slows arthritis progression. It does not prevent it. All CCL-affected stifles develop progressive OA regardless of surgical technique or outcome.
SustainableVet.org confirms: mild arthritis is expected even in successful cases.
Published long-term data (TPLO Info, citing long-term retrospective studies) confirms moderate but significant OA progression in all TPLO cohorts with follow-up extending to 6.8 years.
TPLO produces substantially less OA progression than TTA or lateral suture stabilization, but OA progression is universal.
The appropriate expectation: TPLO minimizes OA development and clinical impact. Long-term management (weight management, exercise modification, joint supplements, and periodic NSAID use for flares) is required in all TPLO dogs.
Myth 6: "Dogs are in severe pain after TPLO"
The truth: modern veterinary anesthesia and pain management protocols produce well-controlled post-operative pain in TPLO dogs. Dogs typically begin bearing some weight within 24 to 48 hours. Pain that is not controlled is a clinical problem requiring medication adjustment -- not an expected feature of TPLO recovery.
SustainableVet.org confirms: it is a misconception that dogs experience severe pain after TPLO surgery; modern multi-modal pain management controls post-surgical pain effectively.
Post-operative pain management typically includes: NSAIDs (carprofen, meloxicam), gabapentin, opioids during hospitalization, local anesthetic nerve blocks at surgery.
Dogs in adequate pain control rest comfortably, bear some weight within days, and show appetite by day 3.
Uncontrolled post-operative pain (dog cannot settle, crying, refuses all weight bearing beyond day 3) indicates a need for pain medication adjustment -- contact your vet rather than accepting it as inevitable.
Myth 7: "TPLO is too risky for most dogs"
The truth: TPLO has a 90 to 95% success rate. The complication rate across all studies is 10 to 34%, but the vast majority of complications are minor (superficial infection, seroma, mild swelling). Serious complications requiring revision surgery occur in fewer than 10% of cases.
Dispomed confirms: overall complication rates are 14 to 34%, but a second surgery is required in less than 10% of cases.
No surgery is without risk.
But for a dog with a torn CCL, the risk of TPLO is substantially lower than the certainty of progressive joint deterioration, pain, and reduced quality of life without surgical treatment.
Myth 8: "TPLO is only for show dogs or working dogs"
The truth: TPLO is appropriate for any dog with CCL rupture that will benefit from restored joint stability -- including middle-aged household pets with no competitive goals.
SustainableVet.org confirms: some pet owners mistakenly believe that TPLO surgery is only for show dogs or high-performance athletes; this is not true; TPLO benefits any dog with CCL disease.
The goal of TPLO is freedom from joint pain and restored ability to perform normal daily activities -- walking, playing, using stairs, sitting and rising comfortably.
These are benefits for every dog, not just sport dogs.
Myth 9: "All dogs with CCL tears need TPLO immediately"
The truth: TPLO is not always an emergency. The timing of surgery should be guided by the veterinary assessment. Partial tears in small dogs may be monitored with conservative management. Dogs with significant concurrent illness may benefit from medical optimization before surgery. The appropriate goal is surgical timing that optimizes anesthetic risk and surgical conditions, not surgical urgency at any cost.
SustainableVet.org confirms: while TPLO surgery is the best treatment for CCL tears, it isn't necessary for every case; for mild or partial tears in less active dogs, alternatives can be effective.
However, in dogs with complete rupture, particularly larger breeds, delay generally produces worse outcomes as OA progresses and the meniscus is exposed to ongoing mechanical insult from the unstable joint.
Myth 10: "If TPLO fails, the dog will never recover"
The truth: most TPLO complications are treatable. Superficial infections resolve with antibiotics. Late meniscal tears are treated with partial meniscectomy. Implant failures can be revised. Osteomyelitis, the most challenging complication, requires prolonged treatment but is often successfully managed.
SustainableVet.org confirms: revision TPLO surgery can be performed if the initial procedure fails; this may involve removing or replacing implants, repositioning the tibial cut, or addressing infections.
The critical factor in outcome from a complication is early detection and prompt treatment. Most complications that are identified and treated early resolve without long-term sequelae.

Frequently asked questions
Is TPLO actually the best treatment for CCL rupture?
For most dogs over 15 to 20 kg, TPLO is the most evidence-supported surgical option, producing the highest rates of long-term function and owner satisfaction in the published literature.
For small dogs, lateral suture stabilization achieves comparable results at lower cost. The choice depends on the individual dog's size, activity level, TPA, and health status.
Can I wait and see how my dog does without surgery?
You can choose conservative management.
The expected outcome in most dogs over 15 kg with complete CCL rupture who do not have surgery is progressive lameness, rapidly advancing OA, ongoing meniscal damage, and reduced quality of life.
Early surgical intervention consistently produces better long-term outcomes than delayed or non-surgical management.
Is the recovery really as strict as described?
Yes. The restriction protocol exists because the plate holds the osteotomy until new bone consolidates -- a process that takes 8 to 12 weeks regardless of how well the dog appears.
A single running or jumping episode before healing is confirmed can displace the plate and require revision surgery.
Will my dog be the same dog after TPLO?
Most owners report their dog is effectively the same dog -- or better than before the CCL rupture -- within 6 to 12 months of surgery.
The 90 to 95% success rate reflects a high proportion of dogs returning to their previous activity level.
Some dogs develop mild age-related stiffness years later as OA progresses, but this is manageable with appropriate care.
Does TPLO cure the CCL problem permanently?
TPLO permanently corrects the biomechanical cause of CCL-related instability in the operated stifle. It does not repair or replace the CCL -- it makes the CCL unnecessary.
It does not prevent CCL disease in the contralateral stifle.

TPLO Implant Failure Signs and Causes
Tibial Plateau Leveling Osteotomy (TPLO) is a common surgery to fix cruciate ligament injuries in dogs. However, sometimes the implants used in TPLO can fail. Recognizing the signs of TPLO implant failure early is important to prevent further damage and pain for your dog.
This article explains the main signs and causes of TPLO implant failure. You will learn what symptoms to watch for and why implants might fail. Understanding these points helps you act quickly and get the best care for your pet.
What are the common signs of TPLO implant failure?
Implant failure after TPLO surgery can show in several ways. Early detection of these signs helps your vet decide if further treatment is needed. Watch your dog closely after surgery for any unusual symptoms.
- Persistent lameness: If your dog keeps limping or refuses to put weight on the leg weeks after surgery, it may indicate implant loosening or breakage.
- Swelling and pain: Noticeable swelling around the surgery site along with pain can suggest implant irritation or infection causing failure.
- Visible deformity: A change in leg shape or abnormal movement can mean the implant is broken or the bone is not healing properly.
- Warmth and redness: Increased warmth or redness at the surgical area often points to infection, which can weaken the implant’s hold.
These signs require prompt veterinary evaluation. Ignoring them can lead to worsening damage and longer recovery times.
Why do TPLO implants fail after surgery?
Several factors can cause TPLO implant failure. Understanding these helps in preventing problems and improving surgical outcomes. Causes include mechanical, biological, and technical issues.
- Improper implant placement: Incorrect positioning during surgery can cause uneven stress and early implant loosening or breakage.
- Infection at surgery site: Bacterial infection weakens bone healing and can cause implant instability or failure.
- Poor bone quality: Dogs with weak or diseased bones may not hold the implant well, leading to failure.
- Excessive activity too soon: Allowing the dog to run or jump before full healing puts extra strain on the implant and risks failure.
Knowing these causes helps vets and owners take steps to reduce implant failure risk.
How can implant failure be diagnosed after TPLO?
Diagnosing implant failure involves a combination of physical exams and imaging tests. Your vet will look for clinical signs and confirm implant status with tools.
- Physical examination: The vet checks for pain, swelling, and abnormal leg movement indicating implant problems.
- X-rays: Radiographs show implant position, bone healing, and any fractures or loosening of the implant.
- CT scans: In complex cases, CT provides detailed images of bone and implant condition.
- Blood tests: These help detect infection or inflammation that may contribute to implant failure.
Early and accurate diagnosis is key to planning effective treatment.
What treatments are available for TPLO implant failure?
Treatment depends on the cause and severity of implant failure. Options range from conservative care to surgery. Your vet will recommend the best plan.
- Rest and restricted activity: Limiting movement helps reduce stress on the implant and supports healing if failure is minor.
- Antibiotics for infection: If infection is present, antibiotics are essential to control bacteria and protect the implant.
- Revision surgery: In cases of implant breakage or severe loosening, surgery to replace or remove the implant may be needed.
- Physical therapy: Controlled rehab exercises improve joint function and muscle strength after treatment.
Timely treatment improves recovery chances and reduces complications.
How can TPLO implant failure be prevented?
Preventing implant failure starts before surgery and continues through recovery. Owners and vets must work together to ensure success.
- Choose experienced surgeons: Skilled surgeons reduce risks by placing implants correctly and managing surgery well.
- Follow post-op care instructions: Strictly limiting activity and following medication schedules help implants heal securely.
- Monitor for infection signs: Early detection and treatment of infection prevent implant weakening.
- Regular follow-up visits: Routine check-ups with X-rays confirm proper healing and implant stability.
Good communication and care improve outcomes and lower failure rates.
What risks do dogs face if TPLO implant failure is untreated?
Ignoring implant failure can cause serious problems for your dog. The implant supports bone healing and joint stability, so failure affects mobility and health.
- Chronic pain: Failed implants cause ongoing discomfort, reducing your dog’s quality of life.
- Joint instability: Without a stable implant, the knee joint may become unstable, leading to arthritis or further injury.
- Bone fractures: Weak implants increase fracture risk around the surgery site.
- Infection spread: Untreated infection can spread to other tissues or the bloodstream, causing severe illness.
Prompt veterinary care is essential to avoid these risks and help your dog recover fully.
Conclusion
TPLO implant failure is a serious complication that can affect your dog’s recovery after cruciate ligament surgery. Recognizing the signs like persistent lameness, swelling, and deformity helps you seek veterinary care quickly.
Understanding the causes such as infection, poor implant placement, and early activity guides prevention and treatment. With proper care, most dogs recover well and regain normal function. Stay alert and follow your vet’s advice to protect your pet’s health.
FAQs
How soon after TPLO surgery can implant failure occur?
Implant failure can happen anytime but is most common within the first 6 to 12 weeks after surgery during the bone healing phase.
Can implant failure cause permanent lameness in dogs?
If untreated, implant failure can lead to chronic pain and joint instability, which may cause long-term lameness or arthritis in dogs.
Is implant removal always necessary if failure occurs?
Not always; minor loosening or infection may be treated conservatively, but severe failure often requires surgical implant removal or replacement.
What signs indicate infection around a TPLO implant?
Signs include redness, swelling, warmth, discharge from the incision, fever, and increased pain at the surgery site.
How can I help my dog recover safely after TPLO surgery?
Follow your vet’s activity restrictions, give prescribed medications, attend follow-up visits, and watch for any unusual symptoms to ensure safe recovery.

Preparing for Your Dog’s TPLO Surgery
Discover simple, stress-free ways to prepare your dog for TPLO surgery. Practical tips for a safe procedure and smooth recovery at home
The better prepared you are before your dog's TPLO surgery, the smoother the procedure and the early recovery will be.
Preparation covers two distinct areas: medical preparation managed with your vet in the days and weeks before surgery, and home preparation completed before your dog comes home.
Both matter and both require specific actions.
Quick answer: Key TPLO surgery preparation steps: complete pre-surgical bloodwork; adjust or discontinue medications as directed; fast the dog 8 to 12 hours before surgery; set up the crate, non-slip mats, and e-collar before surgery day; fill prescriptions in advance; brief all household members.
Key takeaways
- Pre-surgical bloodwork is standard: a CBC and blood chemistry panel confirm the dog can safely handle anesthesia; senior dogs or those with health conditions may need additional testing
- Fasting is non-negotiable: dogs are fasted the night before surgery to prevent anesthetic complications; typically 8 to 12 hours; follow your vet's specific instructions
- Some medications must be stopped before surgery: NSAIDs, certain supplements, and other drugs can increase bleeding or interfere with anesthesia; discuss all medications with your vet at least 1 week before
- The recovery space must be ready before the dog comes home: have the crate, non-slip mats, and supplies in place before surgery day
- Post-surgical medications must be filled before surgery day: NSAID prescriptions and gabapentin should be ready when the dog arrives home
- Household members including children need briefing: educate children about activity restrictions before surgery so they do not inadvertently excite or disturb the recovering dog
Medical preparation: weeks before surgery
Pre-surgical health assessment
Your vet or the surgical team will schedule a pre-surgical examination. This typically includes:
Physical examination: auscultation (heart and lungs), body weight assessment (obesity increases anesthetic and surgical risk), orthopedic examination of the affected limb, and general health screening.
Pre-surgical bloodwork: SustainableVet.org confirms that pre-surgery blood tests usually include a complete blood count and blood chemistry panel to check for anemia, kidney or liver problems, and signs of infection; these tests confirm organs can safely handle anesthesia and healing.
Additional testing for senior or compromised dogs: dogs over 7 to 8 years, those with known health conditions, or those with abnormal screening results may need urinalysis, chest radiographs (to assess cardiac and pulmonary health), or electrocardiography. Cainhoy Vet confirms: for senior pets or those with underlying conditions, additional diagnostics such as X-rays or ECGs may be recommended.
Weight management before surgery
If your dog is overweight, weight reduction before TPLO reduces surgical and anesthetic risk. Midvalley Animal Clinic confirms: increased weight exerts more stress on implants and is an additional hurdle to recovery.
If your vet identifies obesity as a concern, follow their dietary guidance in the weeks leading up to surgery.
Medication review and adjustment
At the pre-surgical consultation, provide a complete list of all medications, supplements, and herbal products the dog is currently taking.
SustainableVet.org confirms: some medications, such as NSAIDs or steroids, may need to be paused before the procedure.
Typical medication guidance:
- NSAIDs (carprofen, meloxicam, aspirin, ibuprofen): typically stopped 5 to 7 days before surgery to reduce bleeding risk
- Steroids (prednisone, prednisolone): typically stopped 5 to 14 days before surgery
- Fish oil and some supplements: may be stopped 1 week before surgery
- Gabapentin and opioids: usually continued as directed
Never stop a prescribed medication without explicit vet instruction.
Pre-surgical bathing
Virginia Vet Centers confirms: your vet may recommend bathing before surgery if you wish, since post-surgical wound care restricts bathing for 10 to 14 days.
Give a bath 1 to 2 days before surgery -- close enough to reduce skin bacteria counts while allowing full drying.
Fasting instructions: the night before surgery
Fasting prevents regurgitation and aspiration of stomach contents under anesthesia -- a potentially fatal complication.
Highlands Vet Hospital confirms: most dogs should stop eating 8 to 12 hours before surgery; always follow your vet's specific instructions.
Standard guidance:
- No food from approximately 10 PM the night before a morning surgery
- Water: rules vary by facility; many allow water until midnight or 6 hours before surgery; follow your vet's specific instructions
- Medications on the morning of surgery: ask your vet specifically which medications (if any) can be given with a very small amount of food or water on the surgery morning
Home preparation: before surgery day
Setting up the recovery space
SustainableVet.org confirms: before your dog comes home, prepare a safe, quiet recovery space with a crate or small room, soft bedding, good airflow, and away from stairs or slippery floors.
Recovery space checklist:
- Crate (sized correctly: stand, turn, lie; not pace) or X-pen in place
- Non-slip mats or yoga mats covering all hard flooring in the recovery area
- Soft, washable bedding inside the crate
- Water bowl accessible at ground level
- Food bowl accessible at ground level
- Baby gates blocking stairs, kitchen, and any rooms the dog should not access
- Furniture blocked or inaccessible to prevent jumping
TPLO Info confirms: you can invest in a gate or large crate to limit movement; educate children in the household as much as possible about the pet's surgery ahead of time.
Supplies to have ready before surgery
Essential:
- E-collar (typically provided by the surgical facility, but confirm in advance)
- Ice pack or bag of frozen peas (cold therapy for the first 3 to 5 days)
- Sling or towel harness for helping the dog rise and walk (for large dogs)
- Leash (4 to 6 foot, not retractable) for all outdoor trips
Nice to have:
- Food puzzle or lick mat (for mental stimulation during confinement)
- Frozen Kong treats prepared and in freezer
- Dog ramp or steps for the car (to load and unload without jumping)
Maplewood Vet confirms: having the right supplies ready before surgery day can help reduce stress and ensure your pet's transition home is as comfortable as possible.
Medication pickup
Prescriptions for post-surgical pain management (NSAIDs, gabapentin) are typically sent to a pharmacy before surgery or dispensed at discharge.
Confirm with your surgical team whether prescriptions need to be filled before surgery day -- this prevents a scramble on discharge day when the dog is in pain and waiting.
Surgery day: what to bring and expect
What to bring:
- Your dog (fasted, no food since the designated cutoff)
- Prior medical records if visiting a new facility (vaccination records, prior bloodwork, medication list)
- The e-collar if provided in advance
- Your contact phone number -- the team will call you during and after surgery
What to expect:
- Drop-off: typically early morning; the dog is admitted, weighed, examined, and IV catheter placed
- Surgery duration: typically 1.5 to 2 hours for TPLO
- Post-surgical hospitalization: most dogs stay overnight; some facilities discharge same day
- Discharge call: your vet will call to update you on how surgery went before discharge
Virginia Vet Centers confirms: most dogs stay at the hospital overnight after TPLO surgery; the veterinary team will provide detailed discharge instructions explaining medications, activity restrictions, wound care, and rehabilitation.
Discharge: what to review before leaving the hospital
At discharge, review:
- Medication schedule (when, how, with or without food)
- Wound care instructions (what to look for, how to manage)
- Activity restrictions (what is and is not allowed)
- Signs that require a call to the vet
- Schedule of follow-up appointments (2-week recheck, 6-week radiograph)

For keeping your dog calm, see how to keep a dog calm after TPLO surgery. For infection prevention, see how can TPLO infections be prevented post-operatively?.
Frequently asked questions
What happens if my dog ate something before surgery?
Call your surgical team immediately. Even a small amount of food can increase anesthetic risk. In most cases the surgery will be rescheduled. Do not wait until surgery day to inform them.
Can I give my dog medications the morning of surgery?
Ask your vet specifically about each medication. Some (like thyroid medications) should be given; others (like NSAIDs) should not. Never assume -- confirm before surgery day.
How do I transport my dog home from surgery?
Line the car with clean towels or a mat. Bring a helper if possible -- one person drives, one sits with the dog.
For large dogs, use a sling or lifting harness to assist getting in and out of the car. Do not let the dog jump in or out of the vehicle.
How long after surgery before I can leave my dog alone?
The first 24 to 48 hours are the highest-risk period. If possible, arrange for someone to be with the dog for the first day and night at home.
After 48 hours, crated dogs can be left alone for reasonable durations (up to 4 to 6 hours). Never leave the dog unsupervised without confinement.
Do I need to prepare other pets in the household?
Keep other pets separated from the recovering dog for at least the first 2 weeks. Excited greetings from other dogs can cause the TPLO dog to jump or spin.
Have a plan for where other pets will be confined when the recovering dog is out of the crate.

TPLO Incision Infection? Symptoms & Prevention
Worried about a TPLO incision infection? Learn the symptoms, causes, and best prevention tips to keep your dog’s recovery smooth and infection-free
TPLO incision infection is one of the most common complications after surgery. Most incision infections are preventable with consistent owner-managed wound care, and most are treatable when caught early.
The window between a superficial incision infection (treatable with antibiotics) and a deep implant infection (requiring surgical intervention) is measured in days -- which is why daily inspection is not optional.
Quick answer: Normal TPLO incision healing shows mild redness fading from day 5, no discharge after day 3, and a clean approximated incision line. Infection signs: spreading redness, increasing warmth, cloudy or malodorous discharge, swelling not resolving, wound edges separating, or lameness worsening. Prevention centers on e-collar compliance, dryness, and daily inspection.
Key takeaways
- Licking is the most common preventable cause of TPLO incision infection: the oral cavity carries S. pseudintermedius that can inoculate the incision; e-collar compliance for 10 to 14 days is the most protective owner action
- The distinction between normal healing and early infection is trajectory-based: mild redness and clear serum discharge are normal for 2 to 3 days; anything worsening from day 5 onward warrants veterinary attention
- Infection signs requiring a same-day call: spreading redness, yellow or green discharge, malodorous discharge, wound dehiscence, or systemic signs alongside local wound changes
- Keeping the incision dry is the second most important prevention measure: bacteria proliferate in moist environments; no bathing or wet-grass walks until incision healing is confirmed by the vet
- Daily inspection at the same time each day creates a baseline: daily comparison of today to yesterday reveals whether the incision is improving or worsening
- Most superficial incision infections resolve with oral antibiotics if treated promptly: treatment escalates significantly if deep implant involvement occurs; early action prevents this escalation
Normal TPLO incision healing: what to expect
Understanding normal healing is the prerequisite for recognizing abnormal changes.
Days 1 to 3: acute inflammatory phase
Normal: the incision is red, mildly swollen, and warm. A small amount of clear to pale yellow serum may seep from the wound edges. The swelling may extend slightly beyond the incision line.
Context: this is the inflammatory phase -- the biological response to surgical trauma. It is expected and appropriate.
Days 3 to 5: peak swelling subsides
Normal: redness should be fading. Swelling should begin to reduce. Any discharge should have stopped by day 3. The incision line should be approximated (edges together and not gaping).
Days 5 to 10: healing consolidation
Normal: redness is minimal or absent. No discharge. The incision line is dry and the skin edges are growing together. The dog may experience some surface itching as new skin forms.
Suture/staple removal: typically at 10 to 14 days. The vet confirms incision healing before removal.
Day 14 onward
Normal: incision is healed, sutures removed, skin intact. Mild surface discoloration (pink to pale) is normal for several weeks. No further discharge.
Signs of TPLO incision infection
Spreading redness (most concerning early sign)
Normal healing produces redness confined to the incision line (typically 1 to 2 mm on each side).
Infection produces redness that spreads outward from the incision -- a widening halo of red skin extending beyond the original margins.
SustainableVet.org confirms: redness that worsens, especially with pain or heat, often accompanies infection. Contact your vet the same day if spreading redness is observed.
Warmth that is increasing rather than decreasing
Mild warmth is normal in the first 3 to 5 days.
Warmth that is increasing at day 7 or beyond -- when normal healing produces cooling -- indicates ongoing active inflammation, typically from infection.
Discharge type and timing
- Clear serum for 24 to 48 hours: normal
- Any discharge after day 3: concerning
- Cloudy, yellow, or green discharge at any stage: infection until proven otherwise
- Malodorous discharge: infection; contact vet immediately
SustainableVet.org confirms: inspect the incision daily for redness, swelling, or discharge; yellow or green discharge is not normal and needs immediate attention.
Wound dehiscence
The incision edges separate, exposing subcutaneous tissue or deeper structures. Most often caused by licking, but can occur from excessive activity, suture reaction, or infection undermining the tissue.
SustainableVet.org (complications article) confirms: if stitches are removed too soon or dehiscence occurs, a vet should assess the wound immediately.
Swelling that is not resolving
Expected swelling peaks at days 2 to 5 and consistently resolves after that.
Swelling that is the same or larger at day 7 as it was at day 3 is not following the expected trajectory.
Systemic signs alongside local changes
Fever (rectal temperature above 39.5 C / 103.1 F), lethargy, reduced appetite, or behavioral changes accompanied by any local wound sign constitute an emergency call. These suggest the infection is systemic.
SustainableVet.org (redness article) confirms: systemic signs including fever, lethargy, or loss of appetite along with redness indicate the infection may be spreading; contact your vet immediately.
Prevention: the actions that matter most
1. E-collar compliance without exception
The e-collar prevents the single most common preventable cause of TPLO incision infection: licking. Even one licking episode directly inoculates the wound with oral bacteria.
SustainableVet.org confirms: even brief periods of licking can introduce bacteria; an Elizabethan collar or medical pet shirt should be used at all times until the incision fully heals.
The e-collar must be worn:
- During sleep
- Unsupervised periods in the crate
- Whenever the dog is not under direct eye contact with the owner
If the dog can reach the incision with the collar on, the collar is the wrong size -- contact the vet for a larger size.
2. Keep the incision dry
Moisture promotes bacterial growth and skin maceration at the incision edges. No bathing or submerging the leg until the vet confirms healing at the 2-week recheck.
During wet weather, minimize wet-grass time on outdoor bathroom trips. Pat the leg dry immediately if it gets wet.
SustainableVet.org confirms: keep the incision clean and dry; avoiding moisture reduces infection risks.
3. Daily incision inspection
Inspect the incision at a consistent time each day. Compare today directly to yesterday. The trajectory (better, same, worse) is more diagnostically useful than any single observation.
Inspection takes 30 seconds. Pick a time (e.g., after the evening bathroom walk) and make it routine.
4. Do not clean with unapproved solutions
Unless instructed by your vet, do not apply hydrogen peroxide, alcohol, iodine, or other antiseptics to the incision. These can damage healing tissue and delay closure.
If cleaning is needed, use the vet-approved solution (typically dilute chlorhexidine or sterile saline).
5. Clean bedding weekly
Bedding in contact with the incision area accumulates skin bacteria. Wash crate bedding weekly in hot water.
6. Hand hygiene before touching the wound
Wash hands before any wound inspection or dressing change. Human skin also carries bacteria capable of contaminating an open or healing incision.
Treatment
Superficial infection (SSI-S): oral culture-directed antibiotics for 2 to 4 weeks; wound cleaning; continued e-collar compliance; wound recheck in 3 to 5 days to confirm response.
Progressing or deep infection: surgical debridement; deep culture; IV or long-course oral antibiotics; imaging to assess implant involvement.
Implant-associated infection: see the dedicated TPLO plate infection guide. Treatment typically includes plate removal once the osteotomy has healed.
For the infection signs guide, see earliest signs of TPLO infection. For the prevention mistakes guide, see post-operative care mistakes that increase TPLO infection risk.
For the staph infection guide, see staph infection after TPLO surgery. For the plate infection guide, see TPLO plate infection signs and treatment.
Frequently asked questions
My dog's incision looks red but the vet said it looks normal at the 2-week recheck. Should I still be worried?
If the vet examined the incision in person at 2 weeks and found it normal, trust that assessment. Post-recheck monitoring continues -- if the incision changes after the recheck, contact the vet.
A single normal exam does not guarantee no infection will develop later.
Can I tell the difference between a seroma and an infection at the incision?
Seromas are soft, fluctuant (fluid-filled), non-painful swellings without redness, warmth, or discharge. Infection produces warmth, redness, possible discharge, and pain. If you cannot clearly distinguish the two, contact your vet for assessment.
The incision looked fine yesterday but today there is yellow discharge. What do I do?
Call your vet the same day. Yellow discharge at any point after the first 2 to 3 days is concerning. Do not wait to see if it resolves.
Keep the e-collar on and do not apply any home remedies to the wound before the vet advises.
My dog keeps trying to lick the incision even with the e-collar. What else can I try?
Ensure the collar is the correct size -- most dogs can reach their hind legs with a too-small collar.
A longer cone, a recovery suit (medical pet shirt), or a contact bandage over the incision site (applied by your vet) can supplement the collar.
Ask your vet about trazodone or gabapentin if anxiety is driving the licking behavior.
Does the incision need to be cleaned every day?
In most cases, no. Daily cleaning is not required and may introduce contamination or irritate healing tissue. Daily inspection is required.
Clean only if the vet specifically instructs it and with the approved solution only.

Dog Meniscus Tear After TPLO: Symptoms and Solutions
Learn the causes, symptoms, and treatment options for dog meniscus tears after TPLO surgery. Find out how to aid recovery and prevent complications
A meniscal tear after TPLO surgery is one of the most recognized post-operative complications.
The medial meniscus is at risk both at the time of CCL rupture and after surgery, when residual instability or degenerative changes can damage tissue that appeared normal during the original procedure.
Recognizing the signs early significantly improves outcomes.
Quick answer: Post-TPLO meniscal tears present as sudden lameness return in a previously improving dog, often with a meniscal click. Late tears occur in 2 to 22% of TPLO cases (RCVS). PubMed found 5.6% late meniscal tear incidence. Treatment is partial meniscectomy; all dogs treated returned to peak limb function per PubMed.
Key takeaways
- Late meniscal tears occur in 2 to 22% of post-TPLO dogs: RCVS confirms this range; a PubMed TPLO arthroscopy study found a 5.6% late meniscal tear incidence
- The hallmark sign is sudden lameness regression in a previously improving dog: RCVS confirms affected dogs display good mobility and then go suddenly lame; this trajectory reversal distinguishes meniscal injury
- The meniscal click is audible but not always present: the absence of a click does not rule out meniscal injury
- The meniscus does not heal on its own: limited blood supply prevents natural regeneration; small tears may be managed conservatively but most require partial meniscectomy
- Partial meniscectomy produces excellent outcomes: all dogs treated by partial meniscectomy returned to peak limb function (PubMed); outcomes at 6 months are comparable to dogs with intact menisci
- Concurrent meniscal tears do not worsen long-term outcomes: AVMA research found similar midterm outcomes for TPLO plus meniscectomy vs TPLO alone, despite more severe arthritis at surgery
The medial meniscus: what it is and why it is at risk
The medial meniscus is a crescent-shaped fibrocartilage structure on the inner surface of the stifle joint. It distributes joint load, provides shock absorption, and stabilizes the joint during weight bearing.
Each stifle has two menisci. The medial is injured far more frequently because it is firmly attached to the tibia and cannot shift away from the abnormal tibial movement during CCL rupture.
SustainableVet.org confirms: the medial meniscus is more prone to injury because it is firmly attached to the tibia. When the tibia slides forward, it is compressed by the femoral condyle.
Why meniscal tears occur after TPLO
Latent tears missed at surgery
At the time of TPLO, the surgeon examines the meniscus through a small arthrotomy or arthroscopy and removes any clearly damaged tissue. However, not all tears are visible at surgery.
Small partial-thickness tears or areas of early degeneration may not be identifiable intraoperatively but progress to complete tears in the weeks or months after surgery.
PMC confirms: post-surgical meniscal pathology may be due to failure of diagnosis at the time of surgery (latent tears) or a result of residual joint instability (post-liminary tears).
Residual joint instability after TPLO
TPLO eliminates the cranial shear force that destabilized the joint. However, the stifle undergoes significant remodeling in the weeks after surgery, and some residual instability may persist during this period.
This can subject a structurally weakened meniscus to loading forces that produce tearing.
SustainableVet.org confirms: meniscal tears after TPLO can occur due to ongoing joint instability before surgery, direct trauma, or degenerative changes.
Progressive degeneration
Older dogs are at higher risk for meniscal tears because the meniscus undergoes age-related degeneration -- loss of collagen fiber organization, reduced cell density, and decreased water content.
PMC confirms: increasing age is a risk factor for medial meniscal tear; the meniscus experiences oxidative stress and abnormal matrix organization that can lead to injury under normal loading forces.
Concurrent vs. late meniscal tears
Concurrent (primary) tears
These are meniscal tears present at the time of TPLO and treated during the original surgery. PubMed data found a concurrent meniscal tear prevalence of 32.2% in dogs undergoing TPLO.
These are removed at the time of the procedure via arthrotomy or arthroscopy.
Late (secondary) tears
These are meniscal tears that develop after TPLO in a previously intact or adequately treated meniscus. The PubMed TPLO arthroscopy study found a late meniscal tear incidence of 5.6%.
RCVS Canine Cruciate Registry confirms late meniscal tears are seen in 2 to 22% of cases.
SustainableVet.org confirms: a secondary meniscus tear often happens weeks or months after the initial procedure and results in immediate pain, limping, and reluctance to move.
Symptoms of a post-TPLO meniscal tear
Sudden lameness regression: the most characteristic sign. A dog making steady progress suddenly becomes lame on the operated leg. This is distinct from the gradual variability of normal TPLO recovery.
Audible or palpable meniscal click: a clicking or popping sound during stifle flexion and extension. SustainableVet.org confirms the knee may produce a clicking sound when moving. The click is heard when the torn meniscal flap is displaced by the femoral condyle.
Pain on stifle manipulation: the dog flinches, vocalizes, or resists when the stifle is flexed through its range. This distinguishes pain from benign mechanical clicking.
Stifle swelling: joint effusion may increase from the baseline level. The joint feels fuller and may be warmer than the contralateral stifle.
Reluctance to bear weight: the dog shifts weight off the operated leg, holds the leg up, or toe-touches only.
SustainableVet.org confirms: symptoms include a sudden return of lameness, difficulty bearing weight, or a clicking or popping sound when the knee moves; dogs may yelp when standing or walking.
Diagnosis
Veterinary evaluation includes:
Physical examination: stifle manipulation to assess pain, range of motion, joint effusion, and presence of a palpable meniscal click. The McMurray-type maneuver and medial meniscal compression test are used to localize meniscal pain.
Radiographs: assess joint effusion (fat pad displacement), osteotomy healing, and implant position. Radiographs do not directly image the meniscus but rule out implant complications as the cause of lameness.
Arthroscopy or arthrotomy: definitive diagnosis. Direct visualization of the meniscus under anesthesia identifies the location, type, and severity of the tear.
Treatment
Conservative management
Small or partial-thickness tears without significant clinical signs can be managed conservatively with:
- NSAIDs for 4 to 8 weeks
- Strict activity restriction
- Joint supplements (omega-3 fatty acids, glucosamine, chondroitin)
- Reassessment if signs do not resolve
SustainableVet.org confirms: small tears may be managed with rest, NSAIDs, and joint supplements; but severe cases often require surgical intervention.
Partial meniscectomy
The definitive treatment for complete or symptomatic meniscal tears. The surgeon removes the damaged portion of the meniscus arthroscopically or via a small arthrotomy, leaving the undamaged portion intact.
The outcomes of partial meniscectomy are excellent. PubMed confirms: all dogs with late meniscal tears treated by partial meniscectomy returned to peak postoperative limb function based on client-assessed outcomes.
AVMA research confirms: treatment for meniscal tear results in significant improvement in lameness, with postoperative outcomes at 6 months comparable to dogs with intact menisci.
RCVS confirms: meniscal tears are treated by removing the torn portion. Dogs with long-term meniscal tears have a bit more osteoarthritis but generally maintain a good quality of life.
Post-meniscectomy recovery
Recovery after partial meniscectomy is typically faster than the original TPLO recovery. The osteotomy is already healed; the additional recovery is for the joint to settle after the meniscectomy.
Most dogs return to normal activity within 4 to 8 weeks.
For the clicking guide, see why is my dog's leg clicking after TPLO surgery?. For the lameness guide, see lameness after TPLO surgery in dogs.
For the infection signs guide, see earliest signs of TPLO infection. For the TPLO complications guide, see 15 common complications after TPLO surgery.
Frequently asked questions
How do I know if it is a meniscal tear or normal recovery variability?
The key is trajectory. Normal recovery shows week-over-week improvement with occasional minor setbacks. A meniscal tear produces a clear regression: the dog was improving, then suddenly lame.
If your dog has been consistently improving and then becomes acutely lame, contact your vet the same day.
Can a meniscal tear be seen on X-ray?
No. Radiographs cannot image cartilage. X-rays assess bone, implant, and joint effusion. A suspected meniscal tear requires arthroscopy or an MRI (less common in veterinary practice) for definitive diagnosis.
Will my dog need another general anesthetic for the meniscectomy?
Yes. Arthroscopy or arthrotomy for partial meniscectomy requires general anesthesia. The procedure is typically shorter than the original TPLO and recovery is faster because the plate and osteotomy are already healed.
Is there anything that could have been done to prevent this?
Not reliably. The risk of late meniscal tears is partly structural (inherent joint instability during healing), partly degenerative (pre-existing meniscal weakness), and partly age-related.
Strict activity restriction during recovery reduces the risk by minimizing the abnormal joint loading that can damage a weakened meniscus, but it cannot eliminate risk entirely.
My dog had a concurrent meniscal tear treated at the time of TPLO. Is the outcome worse?
No.
AVMA research confirms similar midterm functional outcomes for TPLO plus meniscectomy vs TPLO alone in dogs with intact menisci.

Zlig vs TPLO: Which Surgery Is Better for Dogs?
Compare Zlig and TPLO surgeries for dogs to understand which is better for cruciate ligament injuries and recovery outcomes.
Zlig (STIF-VETLIG) is an intra-articular synthetic implant used to reconstruct the cranial cruciate ligament inside the joint a conceptually different approach from TPLO, which changes joint mechanics rather than replacing the ligament.
Both are valid surgical options for CCL rupture in dogs, and the evidence base for Zlig, while smaller than for TPLO, is growing.
Quick answer: Zlig replaces the torn CCL inside the joint using a synthetic fiber implant through small bone tunnels. A 107-case prospective study reported good to excellent results in 97 cases. TPLO has a much larger evidence base and is the ACVS first-choice for large dogs.
Key takeaways
- Zlig reconstructs the CCL inside the joint using a synthetic fiber implant through small bone tunnels; TPLO changes joint geometry instead
- A 107-case prospective study reported good to excellent results in 97 cases: the largest Zlig dataset, single-centre, without controlled TPLO comparison
- TPLO has a significantly larger evidence base: 25+ years of RCTs and ACVS first-choice status for dogs over 60 lbs
- Zlig requires only small bone tunnels, no osteotomy: bone-cutting complications such as delayed union are not relevant
- Implant failure is the primary Zlig-specific risk: the synthetic ligament may stretch or fail over time in large or very active dogs
- Zlig suits bilateral CCL cases in small to medium dogs: both knees can sometimes be addressed in one procedure
How Zlig works
Zlig stands for Z-Ligament. The procedure uses a synthetic fiber implant (marketed as STIF-VETLIG GLOBAL) placed intra-articularly inside the joint capsule to replace the torn CCL.
Unlike extracapsular techniques (lateral suture, Tightrope) which place material outside the joint, Zlig anatomically reproduces the CCL's position within the joint.
The procedure involves drilling small bone tunnels through the femur and tibia at the anatomical insertion points of the CCL.
The synthetic implant is passed through these tunnels and secured, providing immediate mechanical stability similar to the original ligament.
Because there is no bone cutting or tibial rotation, Zlig is less invasive than TPLO and significantly faster to perform.
Recovery may be faster in the early post-operative period for the same reason.
The hund-kreuzbandriss.de clinical commentary (German veterinary reference site) notes: TPLO is a fairly invasive technique that causes irreversible changes.
Intra-articular reconstruction with synthetic fibers only requires small bone tunnels, and complications from osteotomy when they occur are not always easy to correct.
Who makes the Zlig implant?
The Zlig system uses the STIF-VETLIG GLOBAL implant, manufactured in France.
The procedure was developed primarily in France and Germany. It is gaining awareness in other countries but remains far less available than the major TPLO systems.
The highly porous intra-articular fiber design promotes fibroblast penetration and collagen fiber ingrowth over time, which the manufacturers propose increases implant longevity by improving resistance to flexion and torsional forces.
What the evidence shows
Primary Zlig outcome study
A prospective study by Le Doze, Paris, and Pages (2012 to 2021, 107 cases) found good to excellent results in 97 of 107 cases.
The study was conducted at two veterinary clinics in France. This is the most comprehensive Zlig-specific outcome dataset in the veterinary literature.
The hund-kreuzbandriss.de review confirms: Reconstruction of the CCL using the intra-articular synthetic implant STIF-VETLIG GLOBAL leads to good to excellent results in 97 cases in this prospective study from 2012 to 2021.
Limitations of current Zlig evidence
- The primary study is single-centre, non-randomized, and lacks a direct comparison control group
- Long-term data beyond the study's follow-up period is limited
- The procedure has not been evaluated in large-scale randomized controlled trials comparable to those available for TPLO and TTA
- The evidence base is substantially smaller than for TPLO (25+ years of multi-centre data)
TPLO evidence in context
TPLO has been evaluated in prospective randomized studies, force plate gait analysis trials, and multi-year cohort studies across dozens of institutions.
The ACVS recommends TPLO as the most commonly performed procedure for dogs over 60 lbs based on this evidence base.
Zlig vs TPLO: key differences
| Feature | Zlig | TPLO |
|---|---|---|
| Mechanism | Intra-articular CCL reconstruction | Tibial geometry change |
| Invasiveness | Small bone tunnels; no osteotomy | Full proximal tibial osteotomy |
| Surgery time | Shorter | Longer |
| Primary risk | Implant stretch or failure | Bone healing complications |
| Best for | Small to medium dogs; bilateral cases | Large active dogs; steep TPA |
| Evidence base | Growing but limited | Extensive (25+ years) |
| Availability | Limited; specialist-only | Widely available at specialty centres |
| Osteotomy complications | Not applicable | Relevant (delayed union, TTF) |
Patient selection
Zlig may be preferred when:
- Small to medium breed dogs (primary candidate group in current evidence)
- Bilateral CCL rupture in a small dog where simultaneous correction in one anaesthesia event is desired
- Dog owner prefers to avoid the irreversible tibial changes of an osteotomy
- The surgeon is specifically trained in the Zlig technique
TPLO is typically recommended when:
- Dogs over 30 to 40 lbs, especially large and giant breeds
- Dogs with steep tibial plateau angle (TPA) some are not suitable candidates for Zlig due to concurrent patellar luxation or excessive tibial ridge concavity
- The ACVS first-choice recommendation is preferred, with the largest evidence base
- General specialty practice context where Zlig expertise is not available
Hund-kreuzbandriss.de notes: dogs with a steep tibial plateau angle, concurrent patellar luxation, or excessive concavity of the tibial ridge are not good candidates for Zlig.
In these cases, TPLO represents an excellent and often the only alternative.
For the full surgical alternatives overview, see alternatives to TPLO surgery for dogs. For the TPLO vs Tightrope comparison, see Tightrope vs TPLO surgery for dogs.
Frequently asked questions
Is Zlig as effective as TPLO?
For small to medium dogs, the single-centre prospective study shows good to excellent results in the majority of cases.
A direct head-to-head randomized comparison with TPLO in matched patient populations has not been published, so direct effectiveness comparison is not currently possible.
TPLO has a much stronger and broader evidence base overall.
Can large dogs have Zlig surgery?
The current evidence base for Zlig is strongest in small to medium dogs. Large dogs generate higher joint forces that place more demand on the synthetic implant over time.
Many surgeons with Zlig experience reserve it for smaller patients, though there is no absolute size cutoff in the literature.
What happens if the Zlig implant fails?
The synthetic ligament can stretch or rupture over time. If this occurs, the stifle returns to instability and lameness.
Revision surgery would typically involve a different approach TPLO or TTA since the anatomy has not been altered by the Zlig procedure, making revision more straightforward than after an osteotomy.
How long does Zlig surgery take?
Shorter than TPLO in most cases, because no osteotomy is performed.
The exact duration varies by surgeon experience and patient anatomy, but the minimally invasive nature of the procedure is one of its practical advantages.
Where can I find a surgeon who performs Zlig?
Zlig is performed by veterinary surgeons specifically trained in the technique, primarily in France and Germany where the procedure was developed, and increasingly in other countries.
Board-certified veterinary orthopedic surgeons can advise whether the technique is available in your region.

Before and After TPLO Surgery: Dog Health and Recovery Timeline
Discover how TPLO surgery restores mobility in dogs with torn CCL. Learn about recovery timelines, post-op care, and expected outcomes for your pet
TPLO surgery is a major orthopedic procedure that requires careful preparation before surgery and structured management after.
The recovery period -- 8 to 12 weeks of graduated activity restriction, multiple vet visits, and daily wound monitoring -- is as important as the surgery itself.
Most owners who struggle with recovery do so because they underestimated what the post-operative period involves. This guide walks through every phase.
Quick answer: Before TPLO surgery: complete pre-surgical bloodwork, fast 8 to 12 hours, prepare a crate and non-slip mats, fill prescriptions. After TPLO: crate rest weeks 1 to 2, progressive walking weeks 2 to 6, radiographic assessment weeks 6 to 8, activity increase after healing. Muscle recovery takes 4 to 6 months.
Key takeaways
- The home environment must be set up before surgery day: crate, non-slip mats, baby gates, low bedding, and supplies must be in place before the dog arrives home
- Fasting is required before surgery: no food for 8 to 12 hours before general anesthesia; water rules vary by facility
- The first 2 weeks are the most critical and restrictive: no running, jumping, stairs, or off-leash activity; bathroom trips on a short leash only; incision checked daily
- Radiographic assessment at 6 to 8 weeks is the gate that controls activity increase: without imaging confirmation, activity must not increase; radiographs are the only reliable confirmation
- Food intake should be reduced by approximately 30% during recovery: activity restriction rapidly leads to weight gain; extra weight stresses the healing osteotomy
- Full muscle recovery takes 4 to 6 months after bone healing is confirmed: bone healing at 12 weeks and full functional recovery are different endpoints
Before surgery: preparation checklist
Medical preparation (weeks before surgery)
Pre-surgical examination and bloodwork: your vet will perform a full physical examination and order a complete blood count and blood chemistry panel. These confirm the dog can safely handle anesthesia and healing. Senior dogs or those with health conditions may need additional testing.
Medication review: tell your vet all current medications and supplements. NSAIDs, certain supplements, and some other drugs need to be stopped before surgery. Never discontinue a prescription medication without vet instruction.
Weight management: if your dog is overweight, weight reduction before surgery reduces anesthetic and surgical risk. Even a 5 to 10% body weight reduction before surgery is beneficial.
Pre-surgical bathing: bathe 1 to 2 days before surgery if you wish; post-surgical bathing is restricted for 10 to 14 days.
Home preparation (day before surgery)
The recovery space:
- Crate (correctly sized: stand, turn, lie comfortably, not pace) in the main family living area
- Non-slip mats or yoga mats over all hard flooring in the recovery area
- Soft, washable bedding in the crate
- Water and food bowls at floor level
- Baby gates on stairs
- All furniture inaccessible to prevent jumping
Supplies to have ready:
- E-collar (confirm with the surgical facility whether one will be provided)
- Ice pack or bag of frozen peas for cold therapy
- Sling or lifting harness for larger dogs
- Short leash (4 to 6 foot, not retractable)
- Medications filled at the pharmacy before surgery day
SustainableVet.org confirms: before your dog comes home, prepare a safe and quiet recovery space with a crate or small room, soft bedding, good airflow, and away from stairs or slippery floors.
Fasting
No food for 8 to 12 hours before surgery. Water rules vary by facility -- confirm with your vet. Give no food the morning of surgery even if the dog appears hungry.
Surgery day: what to expect
Drop-off: typically early morning. The dog is admitted, weighed, examined, and an IV catheter is placed. IV antibiotics are given before the incision.
The procedure: the surgeon makes a medial incision over the proximal tibia, performs a small arthrotomy to assess the meniscus, makes the curved osteotomy cut, rotates the tibial plateau to approximately 5 degrees, and secures the plate and screws. The wound is closed in layers.
Duration: typically 1.5 to 2 hours.
Post-surgical care: the dog spends several hours in recovery before discharge (same day at some facilities; overnight at others).
Discharge: written instructions for medications, wound care, activity restrictions, and follow-up appointments are provided.
After surgery: week-by-week recovery timeline
Weeks 1 to 2: acute post-surgical phase
Activity: crate rest at all times except bathroom trips. Leash walks of 5 minutes maximum, 3 to 5 times daily. No stairs, no furniture, no off-leash time.
Weight bearing: most dogs begin toe-touching within the first few days. Some do not bear weight for the full 2 weeks -- both presentations are within normal range.
Wound care: e-collar on at all times except supervised eating. Inspect the incision daily at the same time. No bathing or wet incision exposure.
Cold therapy: 10 to 15 minutes of ice pack (wrapped in cloth) applied to the incision, 3 to 4 times daily for the first 3 to 5 days.
Medications: NSAIDs and gabapentin on the exact prescribed schedule. Give NSAIDs with food.
SustainableVet.org confirms: the first two weeks focus on rest and healing; the dog stays confined; short controlled leash walks are for bathroom breaks; check the incision daily for redness, swelling, or discharge.
2-week recheck: incision assessment, suture or staple removal if healing is confirmed, early mobility and pain management review.
Weeks 3 to 6: graduated activity phase
Activity: leash walk duration increases progressively. TPLO Info recommends increasing by up to 5 minutes per week. No off-leash activity. No stairs without guidance. No playing with other pets.
Weight bearing: most dogs should be bearing increasing weight through the operated leg. Three-legged walking during activity is still common but should be decreasing.
Passive range-of-motion exercises: gentle flexion and extension of the stifle, 5 to 10 repetitions, 2 to 3 times daily if the vet has approved.
Veterinary Healthcare Associates confirms: weeks 3 to 4, swelling should decrease; gradual increase in leash walking; passive range-of-motion exercises may begin.
Food management: Medcovet confirms reducing food intake by approximately 30% during the restriction period to prevent weight gain from inactivity.
Weeks 6 to 8: radiographic checkpoint
6-week radiograph (critical): images confirm whether the osteotomy is healing as expected. If healing is progressing, activity can be increased. If healing is delayed, restrictions continue.
If healing is confirmed: leash walks increase to 15 to 20 minutes, physiotherapy begins, short controlled hill walking may begin.
If healing is delayed: investigate for infection or non-union; extend restrictions; consider additional diagnostics.
Veterinary Healthcare Associates confirms: weeks 5 to 6, recheck X-rays may be taken to evaluate healing; improvement in weight-bearing and stability should be evident.
Weeks 8 to 12: consolidation and return to activity
8 to 10 week radiograph (in many protocols): confirms continued healing progression.
12-week radiograph (final major milestone): confirms bone union before lifting restrictions. After this confirmation:
- Running and off-leash play can gradually resume
- Stairs without support
- Normal household access
Post-12-week activity return: progressive reintroduction of activity over the following 4 to 6 weeks rather than an immediate full return.
Animal Outpatient Surgery confirms: in the final phase, your dog can return to normal activity levels, including running, jumping, and playing; continue monitoring for discomfort and maintain a balanced exercise routine.
Long-term: months 3 to 6
Full muscle recovery takes 4 to 6 months after bone healing. During this period:
- Progressive strengthening continues
- Hydrotherapy, balance work, and controlled running rebuild the atrophied operated leg
- Joint supplements (omega-3 fatty acids, glucosamine) are typically started or continued
- Weight management remains critical

Frequently asked questions
How strict does the activity restriction need to be in the first 2 weeks?
Very strict. No exceptions for stairs, sofa access, running, jumping, or unsupervised time without confinement.
A single running or jumping episode in the first 2 weeks can displace the plate before the osteotomy has any mechanical strength.
The restriction is designed to protect a bone that cannot yet protect itself.
My dog is eating less and seems depressed after surgery. Is this normal?
Yes, in the first 3 to 5 days. Anesthesia, post-surgical pain, and opioid medications can reduce appetite and alter behavior.
If the dog is not eating at all by day 3 or shows signs of significant distress, contact your vet.
Most dogs gradually return to normal eating and behavior within the first week.
When can my dog go swimming after TPLO?
Controlled hydrotherapy (underwater treadmill) can begin after the incision is confirmed healed at the 2-week recheck. Open water swimming (lakes, rivers) is typically not recommended until after the 12-week radiographic clearance.
Confirm with your vet in both cases.
Should I put my dog on a diet during recovery?
Reduce caloric intake rather than switching to a formal diet. Medcovet recommends approximately 30% reduction in food intake during the restriction period to prevent weight gain from inactivity.
If your dog was already at an ideal weight, a modest reduction (10 to 20%) is appropriate. Discuss with your vet.
My dog seems completely fine at week 4 and is pulling on the leash. Should I increase activity?
No. Continue the restriction protocol until the 6-week radiograph confirms bone healing progression.
The dog feeling well at week 4 is a positive sign, but bone healing lags significantly behind the dog's perceived comfort.
Dogs routinely feel ready to run before the osteotomy is safe to run on.

DeAngelis vs TPLO Surgery for Dogs
Compare DeAngelis and TPLO surgery for dogs, exploring benefits, risks, recovery, and costs to help pet owners choose the best treatment.
DeAngelis surgery also called lateral suture, extracapsular repair, or ELSS (extracapsular lateral suture stabilization) is one of the oldest and most widely performed CCL repair techniques.
TPLO is the most commonly recommended procedure by the ACVS for dogs over 60 lbs.
Decades of research strongly favor TPLO for larger, more active dogs while supporting extracapsular repair as a cost-effective option for smaller dogs.
Quick answer: TPLO produces superior outcomes in medium and large breed dogs: better limb loading at 8 weeks, higher 1-year function, and slower arthritis progression. DeAngelis surgery is effective for small dogs under 15 to 20 lbs and costs $800 to $1,500 vs $3,000 to $6,000 for TPLO.
Key takeaways
- TPLO produces superior outcomes at 8 weeks and 1 year in size-matched studies: more symmetric loading, higher vertical force, higher owner satisfaction
- DeAngelis surgery is effective in small dogs under 15 to 20 lbs: success rates above 90% reported; significantly worse in larger dogs
- Extracapsular repair relies on periarticular fibrosis for stability; the suture eventually stretches or fails in larger dogs
- DeAngelis surgery costs significantly less: $800 to $1,500 vs $3,000 to $6,000 for TPLO
- Arthritis progression is faster after extracapsular repair than TPLO in multiple studies; TPLO slows OA more effectively
- 10 to 20% of extracapsular repair dogs will require additional treatment for lameness during their lifetime per Today's Veterinary Practice
How each procedure works
DeAngelis surgery (lateral suture / extracapsular repair)
DeAngelis surgery uses a heavy monofilament nylon suture (or, in the TightRope variation, a fiber-tape through bone tunnels) placed outside the joint to mimic the function of the torn CCL.
The suture runs from the lateral fabella behind the femur around to the tibial crest, restraining the cranial drawer movement that occurs with CCL loss.
The suture is not a permanent replacement.
DVM360 confirms that extracapsular stabilization relies on periarticular fibrosis for long-term stability the suture eventually stretches or fails, and joint stability depends on scar tissue formed around the joint during recovery.
DeAngelis surgery does not require bone cutting, specialized equipment, or the steep learning curve associated with TPLO. It is technically accessible to general practice surgeons with appropriate training.
TPLO (Tibial Plateau Leveling Osteotomy)
TPLO addresses CCL rupture by changing joint geometry rotating the tibial plateau so the stifle is mechanically stable without any functioning CCL.
The stability provided by TPLO is bone-based and does not depend on scar tissue or suture integrity over time.
TPLO requires specialized equipment, a radiolucent table, intraoperative radiographs, and surgeon training in the procedure. It is primarily performed at specialty hospitals and by board-certified orthopedic surgeons.
What the clinical evidence shows
Short-term outcomes
DVM360's evidence review found TPLO dogs bear more weight sooner; extracapsular repair dogs hold the leg up for 1 to 2 weeks.
A force plate gait study (ECR n=23, TPLO n=15) found more symmetric limb loading at 8 weeks in TPLO patients compared to extracapsular repair patients at both walk and trot.
Long-term outcomes
Today's Veterinary Practice's evidence-based review reports:
- A randomized blinded clinical trial of 80 dogs found TPLO resulted in higher peak vertical force and higher owner satisfaction at 1 year post-surgery compared to lateral fabellar suture stabilization
- A more recent study showed TPLO outcomes were always better than lateral suture outcomes at any time point up to 1 year
DVM360 notes one early study found no difference at 2 years, but more recent studies consistently show TPLO outperforming extracapsular repair.
Arthritis progression
Today's Veterinary Practice confirms that extracapsular stabilization may result in increased progression of radiographic osteoarthritis compared to TPLO.
Restoring joint mechanics (TPLO) slows cartilage degradation more effectively than temporary stabilization with subsequent fibrosis (extracapsular repair).
Long-term failure
Today's Veterinary Practice reports that 10 to 20% of dogs with extracapsular stabilization will require treatment or reoperation for lameness during their lifetimes, sometimes years after original surgery.
This rate is higher than the expected rate of reoperation-requiring complications after TPLO.
Head-to-head comparison
| Factor | DeAngelis (lateral suture) | TPLO |
|---|---|---|
| Mechanism | Suture + periarticular fibrosis | Bone geometry change |
| Best for | Small dogs under 15 to 20 lbs | Medium and large dogs (30+ lbs) |
| Early weight-bearing | 1 to 2 weeks delayed | Toe-touch within 24 hours |
| Objective outcomes at 1 year | Lower in size-matched studies | Higher |
| OA progression | Faster | Slower |
| Long-term reoperation rate | 10 to 20% | Lower |
| Cost | $800 to $1,500 | $3,000 to $6,000 |
| Equipment required | Basic | Specialized |
| Available at general practice | Yes | Uncommon |
| Evidence base | Extensive | Extensive |
Which dogs are best suited to each?
DeAngelis surgery is appropriate for:
- Small dogs under 15 to 20 lbs with CCL rupture
- Dogs with significant health conditions making a longer anesthetic or more invasive procedure higher risk
- Cases where cost is the primary determining factor
- Older, less active dogs with lower functional demands
TPLO is recommended for:
- Dogs over 30 lbs, especially active and large breeds
- Dogs where long-term joint function and minimal OA progression are the goals
- Working dogs, sport dogs, or highly active pets
- Dogs with steep tibial plateau angles that make extracapsular repair less reliable

Frequently asked questions
Is DeAngelis surgery as good as TPLO?
For small dogs under 15 to 20 lbs, DeAngelis surgery can be as effective as TPLO.
For medium and large breed dogs, the evidence clearly favors TPLO: better short-term function, better 1-year outcomes, slower arthritis progression, and lower long-term reoperation rates.
How much less does DeAngelis surgery cost than TPLO?
Typically $2,000 to $4,500 less per leg. DeAngelis surgery costs approximately $800 to $1,500 at general practices vs $3,000 to $6,000 for TPLO at specialist centres.
For bilateral cases (both knees), the cost difference is doubled.
Does DeAngelis surgery fail more often than TPLO?
In large dogs, yes. The suture stretches and fails in larger, more active patients because the periarticular fibrosis cannot compensate for the higher joint forces.
Today's Veterinary Practice estimates 10 to 20% of extracapsular repair dogs will need further treatment for lameness during their lifetime.
Can my large dog have DeAngelis surgery instead of TPLO?
Technically yes, but the evidence does not support it as the primary recommendation for dogs over 30 lbs.
DVM360 confirms it is possible that larger dogs treated with lateral suture technique may have significantly worse outcomes than those treated with TPLO.
If DeAngelis surgery fails, can TPLO be done afterward?
Yes. TPLO is a standard revision option when extracapsular repair fails or when the dog develops ongoing instability and lameness.
Discuss this with a board-certified orthopedic surgeon if your dog's original repair has not produced adequate results.

How Much Does TPLO Surgery Cost?
Discover the cost of TPLO surgery, key pricing factors, and hidden fees. Learn what affects the price and explore payment options in this detailed guide
TPLO (Tibial Plateau Leveling Osteotomy) is a special surgery used to treat cranial cruciate ligament (CCL) injuries in dogs. By adjusting the tibial plateau angle, TPLO stabilizes the knee joint, allowing for better weight distribution, reducing pain, and improving mobility. It is considered one of the most effective treatments for CCL tears, especially in large or active dogs.
The cost of TPLO surgery can vary widely, usually ranging from $3,500 to $7,000 (or even more). Several factors affect the price, including:
- the location of the veterinary clinic
- the surgeon's expertise
- preoperative diagnostics
- hospitalization
- anesthesia
- post-surgical care
Additional costs may include medications, follow-up visits, rehabilitation, and potential complications.
Specialist hospitals and board-certified surgeons often charge more due to their advanced training and high success rates. Additionally, regional differences in veterinary care costs can affect pricing, making TPLO surgery more expensive in urban areas than in smaller towns.
Factors That Influence TPLO Surgery Costs
Dog’s Size and Weight
Larger dogs need stronger, more durable implants, which raises material costs. They also require higher doses of anesthesia, longer surgeries, and more monitoring during recovery. The complexity of handling a large dog's knee joint makes the surgery more technically challenging, leading to higher fees.
Smaller dogs, while still needing precise surgery, usually have lower implant costs and reduced medication expenses. Veterinary clinics adjust their pricing based on the dog's weight, as it directly impacts the surgery's difficulty, recovery time, and post-operative care, causing variations in overall TPLO surgery costs.
Geographic Location
TPLO surgery costs can vary greatly depending on the clinic's location. In urban areas, prices are usually higher because of increased overhead costs, like facility expenses, staff salaries, and the demand for specialized services. Rural clinics might offer lower prices, but they may not have access to board-certified surgeons or advanced surgical equipment.
Costs also vary between states and countries, affected by regional economic conditions, veterinary licensing fees, and medical supply costs. Pet owners in areas with a high cost of living should expect to pay more, while those in smaller towns might find more affordable options.
Veterinary Clinic’s Pricing Strategy
The type of veterinary clinic also affects TPLO surgery costs. Corporate-owned clinics often have set prices, which may be higher due to overhead and administrative expenses. Private practices might offer more flexible pricing but can also charge higher rates if they have a strong reputation.
Clinics with high demand, advanced equipment, and top-notch facilities usually charge more. Some hospitals include follow-up care in their pricing, while others list these costs separately, impacting the total amount pet owners need to pay. Choosing between different clinic types can significantly influence the final surgery bill.
Severity of the Injury
The extent of ligament damage directly impacts TPLO surgery costs. A partial tear might need less surgical work and result in lower costs, while a complete rupture usually requires more complex reconstruction.
Additional issues like meniscus tears, osteoarthritis, or joint inflammation make the surgery more difficult and increase post-operative care, raising overall expenses.
In severe cases, longer hospital stays, extra imaging, and specialized rehabilitation may be necessary, further increasing costs. Veterinary surgeons evaluate each dog's condition individually, deciding on the level of intervention needed and adjusting the treatment plan as necessary.
Necessary Implants and Materials Used
The type and quality of implants, plates, and screws used in TPLO surgery can greatly affect costs. High-grade titanium or stainless steel implants are more expensive but offer better durability and a lower risk of complications. Customized implants, made for larger or more active dogs, also increase costs due to their specialized design.
Some clinics might use generic implants to keep costs down, while others choose premium, brand-name materials for better long-term results. The choice of implants impacts not only the price but also post-surgery stability, healing time, and overall success rates.
Surgeon’s Expertise and Qualifications
Board-certified veterinary surgeons usually charge more than general veterinarians because of their specialized training and higher success rates. These experts have a lot of experience in orthopedic procedures, which leads to better surgical results.
While general veterinarians can perform TPLO surgery at a lower cost, they might not have the same level of expertise, which could affect recovery and complication rates.
Some pet owners choose experienced surgeons despite the higher cost, focusing on safety, precision, and long-term joint health for their dogs. Selecting a skilled surgeon often results in faster recovery and fewer post-surgical problems.
Regional Cost Comparison
The cost of TPLO surgery varies significantly by country and location due to differences in veterinary fees, cost of living, and availability of specialized surgeons. Below is a general comparison of TPLO surgery costs in different regions:
| Region | Average Cost Range (Per Knee) | Key Factors Affecting Cost |
|---|---|---|
| United States | $3,500 – $10,000 | Higher costs in major cities like New York and Los Angeles due to demand and overhead; rural clinics may charge less. |
| Canada | $3,500 – $8,000 | Urban centers like Toronto and Vancouver have higher fees; fewer specialists in remote areas may drive up costs. |
| United Kingdom | £3,000 – £6,500 ($3,800 – $8,200) | London and other metropolitan areas charge more; the availability of pet insurance can impact affordability. |
| Australia | AUD 4,000 – AUD 9,000 ($2,600 – $5,900) | Higher in cities like Sydney and Melbourne; regional clinics may offer lower rates but limited specialist availability. |
Urban clinics usually charge more because of higher operating costs and greater demand for specialist services. In contrast, rural clinics often have lower prices but may not have board-certified surgeons.
Additionally, pet insurance can greatly affect out-of-pocket costs, as some policies cover part or all of the TPLO surgery expenses, depending on the region and the plan.
Cost Variations by Dog Size
The cost of TPLO surgery varies based on the size of the dog, mainly because of differences in implant needs, anesthesia dosage, and surgical complexity. Here's a breakdown of approximate costs by weight category:
- Small Dogs (<40 lbs) – Approximately $4,450
Smaller dogs need smaller implants and less anesthesia, making their surgery a bit less complex. However, the cost is similar to larger dogs because specialized skills and equipment are still necessary. - Medium Dogs (40–70 lbs) – Approximately $4,450
Dogs in this weight range usually need standard-sized TPLO plates, keeping costs similar to small dogs. The surgical method and recovery care are also similar. - Large Dogs (70–100 lbs) – Varies Based on Plate Size
Costs increase for larger dogs due to the need for stronger, larger TPLO plates. Some clinics charge extra for custom implants that offer better durability and long-term joint support. - Extra-Large Dogs (>100 lbs) – $4,450 to $5,950
Giant breeds require reinforced implants, more anesthesia, and longer surgery time, which raises the overall cost. Post-surgical care and rehabilitation may also be more intensive, further affecting expenses.
Larger dogs often have higher long-term care costs, including pain management and physical therapy, making post-operative planning crucial for their recovery.
What’s Included in the TPLO Surgery Cost?
The total cost of TPLO surgery usually includes several components to ensure a safe procedure, proper recovery, and post-operative care. Here is a breakdown of what is typically included:
- Pre-Surgical Bloodwork: Before surgery, veterinarians perform blood tests to check the dog’s overall health, making sure they can safely handle anesthesia and recover without issues.
- X-Rays for Diagnosis and Surgical Planning: Preoperative X-rays are needed to confirm the severity of the CCL tear and determine the exact tibial angle for surgical correction. Post-surgical X-rays may also be taken to ensure the implant is properly placed.
- Anesthesia and Surgical Monitoring: TPLO surgery requires general anesthesia, which is carefully given and monitored throughout the procedure. The cost includes oxygen support, IV fluids, and continuous tracking of vital signs to ensure the dog's safety.
- Actual TPLO Surgical Procedure: This includes the orthopedic surgery itself, where the surgeon makes a precise bone cut, repositions the tibial plateau, and secures it with plates and screws.
- Post-Operative Pain Medications: Pain management is crucial for recovery. The cost typically includes anti-inflammatory drugs, antibiotics, and pain relievers to prevent infection and discomfort.
- Follow-Up Visits and Check-Ups: Most clinics include at least one or two post-surgery appointments to monitor healing and assess the dog's progress. Additional visits may be needed if there are complications.
- Physical Therapy or Rehabilitation Sessions (If Included): Some veterinary clinics offer rehabilitation programs like hydrotherapy or therapeutic exercises to help improve recovery. However, not all clinics include these services in the base surgery cost.
Each clinic has its own pricing structure, so it's important to check what is included to avoid unexpected costs during recovery.
Hidden or Unexpected Costs of TPLO Surgery
While TPLO surgery is highly effective, some additional expenses may arise depending on the dog's recovery process and the clinic’s pricing structure.
- Emergency Care for Complications: Although rare, complications such as implant loosening, poor bone healing, or excessive swelling may require extra treatment. Even with lower infection risks using Simini Protect Lavage, issues like implant irritation or allergic reactions might still occur, needing additional veterinary care.
- Additional Pain Management Medications: While most TPLO surgery packages include standard pain medications, some dogs might need stronger or longer-term pain relief, especially if they have pre-existing joint issues or heal slowly.
- Post-Surgery X-Rays for Recovery Monitoring: Some veterinary clinics charge separately for follow-up X-rays at 6-8 weeks post-surgery to confirm proper bone healing. If not included, these can cost $150 to $300 per session.
- Rehabilitation and Therapy (If Not Included in Base Cost): Hydrotherapy, laser therapy, or guided rehabilitation exercises can enhance recovery but may add $50 to $100 per session.
With advanced infection control measures like Simini Protect Lavage, unexpected costs related to post-operative infections are minimized, making TPLO recovery more predictable and reducing financial uncertainties.
Payment and Financing Options for TPLO Surgery
TPLO surgery is a significant financial commitment, but various payment and financing options can help manage the cost. Pet owners should explore different ways to reduce financial strain while ensuring their dog gets the necessary treatment.
- Flexible Payment Plans Offered by Some Clinics: Many veterinary clinics offer in-house payment plans, allowing owners to pay in installments instead of a lump sum. These plans typically require a deposit upfront, with the remaining balance spread over several months.
- Discounts for Upfront Payments: Some clinics provide discounts for paying in full before the surgery. This option can help save money, as interest fees from financing plans are avoided. It's worth asking if a prepayment discount is available.
- Third-Party Financing or Personal Loans: Veterinary financing companies like CareCredit and Scratchpay offer low-interest or interest-free short-term loans for pet medical expenses. Personal loans or credit cards can also be an option, but they may come with higher interest rates.
- Pet Insurance Coverage Considerations: Not all pet insurance plans cover TPLO surgery. Policies that include orthopedic conditions or CCL injuries may reimburse a portion of the cost. Companies like Trupanion, Healthy Paws, and Embrace often cover TPLO surgery, but pre-existing conditions are typically excluded. Pet owners should check waiting periods and coverage limits before proceeding.
Discussing these options with the veterinary clinic can help find the best financial solution for your dog’s surgery.
Additional Considerations Before Committing to TPLO
Before proceeding with TPLO surgery, it’s important to consider potential risks, unexpected costs, and pricing differences between clinics to ensure you are fully prepared for the financial and medical aspects of the procedure.
Risks of Unexpected Complications and Added Cost
While TPLO surgery has a high success rate, complications such as implant failure, delayed bone healing, or improper post-operative care can lead to additional expenses. Some dogs may require extended rehabilitation, extra pain management, or revision surgery, increasing costs beyond the initial estimate.
While infection risks are lower when using Simini Protect Lavage, other factors like poor post-op care or underlying health conditions may still affect recovery.
Comparing Quotes from Different Veterinary Clinics
Prices for TPLO surgery can vary significantly between clinics based on location, surgeon expertise, and included services. It’s recommended to get multiple quotes, ensuring you compare what’s included, such as pre-op tests, X-rays, follow-up visits, and rehabilitation. Some clinics offer payment plans or discounts, making it essential to explore all financial options before committing.
Taking the time to understand potential costs and evaluate different providers can help ensure the best possible care for your dog while managing expenses effectively.
Is TPLO Worth the Cost? Long-Term Financial Benefits
While TPLO surgery is expensive, it is often a cost-effective investment in a dog’s long-term health. Choosing not to proceed with TPLO can lead to chronic pain, progressive arthritis, and long-term medical expenses that may exceed the cost of surgery.
Cost of Not Doing TPLO
Without surgical intervention, a torn cranial cruciate ligament (CCL) leads to joint instability, inflammation, and arthritis progression. Managing these issues requires lifelong pain medications, anti-inflammatory drugs, physical therapy, and joint supplements—costs that add up over time. Many dogs that do not undergo TPLO eventually experience injury in the opposite knee, further increasing medical expenses.
TPLO as an Investment in Mobility and Health
TPLO surgery restores knee stability, reduces pain, and allows for full weight-bearing movement, enabling dogs to return to normal activity levels. Unlike conservative management, TPLO prevents further joint deterioration, reducing the need for ongoing medical intervention.
How TPLO Saves Money in the Long Run
While conservative treatments like bracing, pain management, and therapy may seem cheaper initially, they often require years of continuous care.
TPLO, on the other hand, is a one-time surgical cost that provides a permanent solution, minimizing future expenses and improving a dog’s quality of life.

Conclusion
TPLO surgery is a major financial commitment, with costs usually ranging from $3,500 to $10,000 per knee. This price covers pre-surgery diagnostics, anesthesia, the surgery itself, post-operative care, and follow-up visits. However, there may be extra costs for rehabilitation, post-surgery X-rays, and emergency care for any complications.
Before deciding on TPLO, pet owners should think about their dog's size, the severity of the injury, the surgeon's expertise, and their location, as these factors significantly affect the total cost. Comparing quotes from different clinics, checking pet insurance coverage, and looking into financing options can help manage expenses.
Although the initial cost is high, TPLO offers a long-term solution, lowering the risk of arthritis and removing the need for lifelong pain management. In the long run, it is often more cost-effective than conservative treatments. Investing in TPLO means better mobility, pain relief, and an improved quality of life for your dog.
FAQs
How much does TPLO surgery cost on average?
The average cost of TPLO surgery ranges from $3,500 to $10,000 per knee, depending on clinic location, surgeon expertise, diagnostic tests, anesthesia, and post-operative care. Urban clinics and specialty hospitals tend to charge more. Additional costs may arise from follow-up visits, rehabilitation, and pain management, which are sometimes not included in the base price.
How much does it cost to remove a TPLO plate?
The cost of TPLO plate removal varies depending on factors such as the veterinary clinic, location, and the complexity of the procedure. On average, the cost ranges from $800 to $2,500. This typically includes anesthesia, surgical fees, and post-operative care. Plate removal is usually recommended only if complications arise, such as infection, irritation, or persistent pain. Some clinics may offer a lower cost if the removal is performed at the same facility where the TPLO surgery was originally done. Always consult your veterinarian for an accurate estimate based on your dog's specific case.
Why is TPLO surgery so expensive?
TPLO surgery is costly due to its complex nature and specialized equipment. It requires advanced surgical skills, high-quality implants, general anesthesia, and extensive post-operative care. Additionally, board-certified veterinary surgeons charge more due to their expertise and success rates. Factors like pre-surgical diagnostics, follow-up X-rays, and rehabilitation therapy further increase the total cost.
Can pet insurance cover TPLO surgery?
Yes, some pet insurance plans cover TPLO surgery, but coverage depends on the policy terms and pre-existing condition exclusions. Companies like Trupanion, Healthy Paws, and Embrace often reimburse part of the cost if the injury was not diagnosed before the policy started. Owners should check waiting periods, deductibles, and reimbursement limits before relying on insurance.
Are there cheaper alternatives to TPLO surgery?
Alternatives include lateral suture stabilization (Extracapsular Repair) and TTA (Tibial Tuberosity Advancement), which may be cheaper but are less effective for larger, active dogs. Conservative management with medications, weight control, and bracing can temporarily relieve symptoms but does not fully restore joint function and may lead to long-term arthritis.
What are the hidden costs of TPLO?
Hidden costs may include post-surgical X-rays ($150–$300 per session), extended pain management, rehabilitation therapy ($50–$100 per session), and emergency care for complications. While infection risks are lower with Simini Protect Lavage, some dogs may still require additional medications or follow-up procedures, adding to the overall cost.
How can I save money on TPLO surgery?
Pet owners can save money by comparing quotes from different clinics, asking about payment plans, checking pet insurance coverage, and looking for upfront payment discounts. Some veterinary schools offer lower-cost surgeries performed by supervised students. Financing options like CareCredit and Scratchpay also help spread out payments.
Does the cost of TPLO include physical therapy?
Not always. Some veterinary clinics bundle rehabilitation sessions in the total cost, but many charge separately. Physical therapy, including hydrotherapy, laser therapy, and therapeutic exercises, can cost $50 to $100 per session. It is essential to confirm with the clinic whether post-operative rehab is included.
Is TPLO surgery a one-time cost, or will my dog need additional procedures?
TPLO surgery is generally a one-time procedure, but additional costs may arise for post-surgery check-ups, pain management, and rehabilitation. In rare cases, complications like implant failure or infections may require revision surgery, adding to the expenses. However, with proper post-operative care, most dogs recover well without further surgical intervention.

Bilateral TPLO Surgery Explained
Comprehensive guide to bilateral TPLO surgery for dogs, covering procedure, recovery, benefits, risks, and cost considerations for better mobility
Bilateral CCL (cranial cruciate ligament) disease -- affecting both stifle joints -- is common in dogs.
Midvalley Animal Clinic confirms 30 to 40% of dogs with unilateral CCL rupture will eventually develop rupture of the contralateral CCL.
When both stifles are significantly affected, the decision between simultaneous bilateral TPLO and staged TPLO is one of the most important surgical planning discussions an owner will have.
Quick answer: Simultaneous bilateral TPLO operates on both stifles in one anesthetic event, offering a single recovery period and lower total cost. Staged TPLO operates on one leg at a time, reducing anesthetic risk. Simultaneous is preferred for healthy, large dogs with both stifles unstable. Staged is preferred for older, smaller, or compromised dogs.
Key takeaways
- 30 to 40% of dogs with unilateral CCL disease develop contralateral CCL rupture: bilateral TPLO may be planned proactively at presentation or urgently when the second CCL ruptures during recovery
- Simultaneous bilateral TPLO offers a single anesthetic event and shorter overall recovery: both knees heal together; total cost is lower than two staged surgeries
- Staged bilateral TPLO reduces surgical risk: each surgery is shorter; the dog has one functional leg during recovery; preferred for older or medically compromised dogs
- The critical challenge of simultaneous bilateral TPLO is recovery: with both rear legs restricted, owners must provide intensive physical support (slings) for the first 2 to 3 weeks
- PubMed research (176 bilateral TPLO cases) found no significant difference in overall complication rates between simultaneous and staged approaches in appropriately selected patients
- Large dogs with strong front limbs handle simultaneous TPLO better: smaller or weaker dogs benefit from the staged approach due to greater difficulty bearing weight on two compromised rear legs
Why bilateral CCL disease is common
CCL disease in dogs is degenerative, not purely traumatic.
The same factors that caused one CCL to rupture -- degenerative fiber changes, abnormal tibial plateau angle, breed predisposition, obesity, and mechanical overload -- are typically present in both stifles.
When a dog ruptures one CCL, it often shifts weight onto the contralateral leg, increasing the load on the already-compromised contralateral CCL. This accelerates degeneration and the timeline to rupture.
The clinical implication: even when only one stifle is symptomatic at presentation, the surgeon will typically assess both stifles.
Pre-operative radiographs of both stifles help determine whether the contralateral joint shows early instability, effusion, or an elevated TPA that warrants planning for bilateral surgery.
Simultaneous bilateral TPLO
Overview
Both stifles are operated on during a single general anesthetic event. The dog is positioned, the first TPLO is performed, the dog is repositioned, and the second TPLO is performed.
Total surgical time is approximately 3 to 4 hours.
Advantages
Single anesthetic event: the dog is exposed to general anesthesia once rather than twice. Each anesthetic event carries inherent risk; eliminating one event reduces cumulative anesthetic risk.
Faster total recovery: both legs heal simultaneously. Rather than 8 to 12 weeks of restriction for the first leg, then a second 8 to 12 week restriction for the second leg, the dog completes one restriction period covering both.
SustainableVet.org confirms: when both knees are corrected in a single surgery, the dog undergoes just one healing phase rather than two separate ones, returning to normal activity sooner.
Lower total cost: while the simultaneous surgery costs more than a single TPLO, it is less than two completely separate procedures with individual hospitalization, anesthesia fees, and post-operative care expenses.
SustainableVet.org confirms: simultaneous TPLO often reduces overall costs by avoiding duplicate anesthesia, hospitalization, and post-operative care fees.
Risks and challenges
Both rear legs are compromised simultaneously: the dog cannot transfer weight to a strong rear leg during the recovery period. All rear-limb support requires either front-limb loading (difficult for large breeds) or active owner assistance via sling.
Increased owner demand: SustainableVet.org confirms post-surgical care is more challenging because the dog cannot rely on a strong leg for support, requiring owners to provide intensive assistance.
Longer anesthetic duration: total surgical time of 3 to 4 hours for bilateral vs. 1.5 to 2 hours for unilateral increases the physiological burden of anesthesia and surgery.
Potentially higher complication rate in some populations: the PubMed 176-case study compared simultaneous and staged TPLO complications and found no significant overall difference, but the study population was highly selected.
Staged bilateral TPLO
Overview
The more significantly affected stifle is operated on first. After a full recovery (typically 8 to 12 weeks until bone healing is confirmed), the second stifle is operated on.
Advantages
Reduced surgical risk per event: each procedure is a standard unilateral TPLO, carrying the same risk profile as any single TPLO.
One functional rear leg during recovery: the dog can weight-bear on the unoperated leg immediately after the first surgery. This simplifies nursing care significantly and allows most dogs to stand and toilet independently.
Better option for older or compromised dogs: SustainableVet.org confirms older dogs or those with other health issues benefit from a staged approach to reduce surgical risk. Dogs with cardiac, renal, hepatic, or respiratory disease may not tolerate a 3 to 4 hour bilateral procedure safely.
Disadvantages
Two separate anesthetic events: two exposures to general anesthesia over a 3 to 6 month period.
Longer total recovery timeline: the dog may not reach full bilateral function for 6 to 9 months or longer from the date of the first surgery.
Higher total cost: two separate surgeries, two hospitalizations, two sets of post-operative medications and supplies.
Risk of contralateral rupture during the first recovery: the contralateral leg bears additional load during the first recovery period, accelerating degeneration. In some dogs, the second CCL ruptures acutely during the first recovery -- this forces an emergency decision about timing of the second surgery.
Which approach is right for a given dog?
Generally prefer simultaneous bilateral TPLO when:
- Both stifles are confirmed significantly unstable at presentation
- The dog is young, healthy, and large with strong front limb musculature
- The owner is able to provide intensive physical support during the bilateral recovery period
- The surgeon is experienced with bilateral TPLO technique
- Financial considerations favor the single-event approach
Generally prefer staged bilateral TPLO when:
- Only one stifle is currently significantly symptomatic (the second may be monitored and staged only if it progresses)
- The dog is older, small, or has significant concurrent health conditions
- The owner's ability to provide intensive bilateral recovery support is limited
- The anesthetic risk for a prolonged bilateral procedure is elevated
SustainableVet.org confirms: large dogs with strong front limbs may handle simultaneous TPLO better, while smaller or weaker dogs may benefit from a staged approach.
Bilateral TPLO recovery: what to expect
Simultaneous recovery
Weeks 1 to 2: the most demanding period. Both rear legs are compromised. The dog requires a sling for all mobility. Bathroom trips require active owner support.
Crate rest at all other times.
Weeks 2 to 6: gradual improvement. Both legs begin partial weight bearing. Sling use may reduce but is still needed for most dogs on stairs or uneven surfaces.
Weeks 6 to 12: radiographic assessment of both osteotomies. Activity increases based on healing of both legs.
Key equipment for bilateral TPLO recovery
- Lifting harness or rear-end sling (essential, not optional)
- Non-slip mats throughout the house
- Ramps for car access (no jumping in or out)
- Low dog beds at floor level

Frequently asked questions
How will I know if my dog needs bilateral TPLO?
Your vet will assess both stifles during the physical examination.
Signs that the contralateral stifle is also affected include drawer sign or tibial thrust on the second side, joint effusion on radiographs, or intermittent lameness on both rear legs.
Both stifles are typically radiographed at the pre-operative planning visit.
Can the second CCL rupture while my dog is recovering from the first TPLO?
Yes. This is one of the main risks of staged TPLO. The unoperated leg bears more weight during recovery, accelerating degeneration.
If the second CCL ruptures acutely, the dog becomes bilateral suddenly and the timing of the second surgery must be reassessed with your vet.
Is bilateral TPLO safe for large breeds?
Yes, when appropriately selected. Large dogs with good front limb strength typically handle the bilateral recovery better than small dogs.
The challenge is the nursing care requirement, which is significant regardless of size. Ensure you have the physical ability to support a large dog in a sling before committing to simultaneous surgery.
My dog needs bilateral TPLO but I can only afford one surgery now. What should I do?
This is a common situation. Staged TPLO is appropriate and legitimate. Operate on the more severely affected stifle first and monitor the second closely.
Discuss weight management and controlled activity to reduce load on the second stifle during the first recovery. Plan financially for the second surgery.
Do both TPLO plates stay in permanently?
Yes, unless a complication (infection, implant failure) necessitates removal.
If both plates require removal, it can be done as a single procedure or staged, depending on the reason for removal and the healing status of each osteotomy.

Common Causes of Limping in Dogs Post-TPLO Surgery
Discover common causes of dog limping post-TPLO surgery and explore solutions for regaining your dog's comfort and mobility a year later
Some degree of lameness after TPLO surgery is expected. The surgery involves a bone cut and plate fixation, and the dog's leg needs weeks to heal.
The clinical challenge for owners is distinguishing between normal post-surgical lameness (which requires patience) and lameness that indicates a complication (which requires prompt veterinary attention).
The answer depends heavily on timing, trajectory, and accompanying signs.
Quick answer: Normal post-TPLO lameness should show consistent week-over-week improvement. The most common pathological causes are: surgical site infection, late meniscal tear, implant loosening, muscle atrophy, delayed bone healing, and progressive osteoarthritis. The key signal is trajectory reversal -- lameness worsening after improvement or failing to improve for 2 or more weeks.
Key takeaways
- Some lameness is normal throughout the first 8 to 12 weeks of TPLO recovery: mild limping that improves gradually over 6 to 12 weeks is typical; the key variable is trajectory
- Trajectory reversal is the key warning sign: lameness that worsens after improvement, or fails to improve for 2 or more consecutive weeks, warrants veterinary evaluation before the next appointment
- Late meniscal tear is a recognized cause of sudden lameness regression: recurrence of lameness after initial resolution can indicate meniscal injury; it occurs in 2 to 22% of TPLO cases
- Muscle atrophy is a commonly underappreciated cause of persistent lameness: the affected leg loses muscle mass during restriction; inadequate rehabilitation leaves an asymmetric gait
- Progressive osteoarthritis is the most common cause of chronic mild lameness starting months after surgery; TPLO slows but does not stop this process
- Implant failure and infection must be ruled out for lameness that is worsening or not responding to conservative management; radiographs and culture are required for diagnosis
Normal post-surgical lameness: what to expect
Week 1 to 2
Most dogs are significantly lame in the first 1 to 2 weeks. They may toe-touch only or hold the leg off the ground entirely.
This is the acute post-surgical inflammatory phase combined with the effects of anesthesia wearing off.
SustainableVet.org confirms: some lameness is expected after TPLO surgery, especially in the first few weeks; normal recovery lameness is mild limping that improves gradually over 6 to 12 weeks.
Week 2 to 6
Consistent improvement should be visible week over week. By week 4, most dogs should be bearing significant weight on the operated leg during slow walking.
Three-legged walking during activity is still common but should be decreasing.
Week 6 to 12
Most dogs should be consistently weight-bearing on the operated leg. By week 12, most are nearly normal for household activities.
Radiographic confirmation of bone healing at weeks 6 to 8 and 12 guides when activity can increase.
Pathological causes of post-TPLO lameness
1. Surgical site infection (SSI)
Timing: most commonly weeks 1 to 4, but can occur at any stage (including months later for deep implant-associated infections).
Mechanism: bacterial contamination of the incision or implant causes inflammation and pain at the plate site, which produces or worsens lameness.
Signs accompanying lameness: redness, warmth, swelling, or discharge at the incision or plate site.
Action required: same-day veterinary contact for any infection signs alongside lameness.
2. Late meniscal tear
Timing: typically weeks 4 to 12 post-surgery, though it can occur months later.
Mechanism: the meniscus, which may have been structurally weakened before surgery or had a small tear not detected at surgery, fails under load during the recovery period.
Signs accompanying lameness: audible or palpable meniscal click; pain on stifle manipulation; sudden lameness regression in a dog that had been improving.
Animal Outpatient Surgery confirms: if lameness resolves after TPLO and recurs at a later time, this can be an indication of meniscal injury.
Action required: veterinary evaluation within 24 to 48 hours; arthroscopy or arthrotomy for diagnosis and partial meniscectomy for treatment.
3. Implant loosening or failure
Timing: most common in the first 6 to 12 weeks when the osteotomy is still healing and the plate bears the full load. Can also occur later from chronic infection or late trauma.
Mechanism: excessive activity before the osteotomy heals applies forces that exceed the plate's tolerance; screws pull out or the plate bends.
Signs accompanying lameness: sudden severe lameness; pain at the plate site; sometimes audible clicking or grinding; radiographic evidence of screw loosening or plate migration.
SustainableVet.org confirms: signs of implant failure include ongoing limping, pain, swelling around the implant site, and unusual clicking or grinding sounds from the joint.
Action required: same-day emergency veterinary contact for sudden severe lameness; radiographs urgently required.
4. Muscle atrophy and weakness
Timing: most prominent from weeks 4 to 12; persists for months if rehabilitation is inadequate.
Mechanism: during activity restriction, the operated leg muscles (quadriceps, hamstrings, hip extensors) atrophy rapidly. Asymmetric muscle mass leads to asymmetric weight distribution and abnormal gait patterns that present as persistent limping.
Vetplayas confirms: limited mobility during recovery leads to muscle loss and decreased strength. This imbalance results in abnormal gait patterns and subsequent limping.
Signs: visible muscle asymmetry (operated thigh smaller than opposite); lameness that worsens with activity and improves with rest; no accompanying warmth, redness, or plate-site changes.
Action required: rehabilitation assessment; physiotherapy to rebuild muscle mass.
5. Delayed bone healing
Timing: identified at the 6 to 8 week radiographic assessment.
Mechanism: the osteotomy is not showing expected callus formation and cortical bridging. Common causes include infection, excessive activity, poor blood supply, or systemic factors (NSAIDs at high dose for extended periods, nutritional deficiencies).
Signs: persistent lameness at a level that does not match the expected trajectory; confirmed radiographically.
Action required: veterinary investigation for underlying cause; extended activity restriction; sometimes additional diagnostics (culture to rule out occult infection).
6. Delayed union or non-union
Timing: identified at 12+ weeks when bone healing should be complete.
Mechanism: the osteotomy fails to heal. The plate is subject to continued cyclic loading without the protection of consolidated bone, increasing implant failure risk.
Action required: specialist reassessment; may require bone grafting, implant revision, or extended medical management.
7. Progressive osteoarthritis
Timing: typically becomes clinically apparent after 6 to 12 months.
Mechanism: CCL disease initiates an irreversible arthritis process in the stifle. TPLO reduces but does not eliminate arthritis progression. Over months and years, arthritis produces chronic mild lameness, particularly after rest and exercise.
Signs: stiffness that improves with movement; lameness worse in cold weather or after long periods of rest; gradual worsening over months; bilateral involvement common.
SustainableVet.org (failure symptoms article) confirms: limping 2 years post-TPLO may result from arthritis, implant irritation, meniscal damage, or muscle atrophy.
Action required: long-term management (joint supplements, weight management, NSAIDs for flares, hydrotherapy, physiotherapy).
8. Contralateral CCL rupture
Timing: any time during or after recovery from the first TPLO.
Mechanism: the contralateral CCL, subject to the same degenerative process and bearing extra load during recovery, may rupture. The dog appears to start limping on the opposite leg.
Signs: what appears to be recovery from one side suddenly accompanied by new lameness on the opposite side; the dog may be lame on a different leg or bilateral.
Action required: veterinary evaluation; bilateral CCL disease may require staged or simultaneous bilateral TPLO.
How to assess the trajectory at home
Create a simple weekly log: note the leg-use pattern (full bearing, toe-touching, three-legged) and the dog's willingness to walk at each prescribed walk time.
Compare week 4 to week 3, week 6 to week 5. If the pattern is consistently improving, continue the protocol. If it is static or worsening, contact your vet.
For the lameness guide, see lameness after TPLO surgery in dogs. For the TPLO failure signs guide, see signs of TPLO failure in dogs and when to see a vet.
For the meniscal tear guide, see dog meniscus tear after TPLO surgery. For the infection guide, see earliest signs of TPLO infection.
Frequently asked questions
My dog was progressing well at week 4 but is limping more at week 5. What do I do?
A single week of regression after a period of progress is not necessarily pathological -- increased activity, weather changes, or an off day can cause temporary setbacks.
But if the worsening persists for 2 weeks, or is accompanied by any infection signs, contact your vet.
Monitor closely and reduce activity to the week 2 level for 24 to 48 hours to see if the leg settles.
My dog is still limping 4 months after TPLO surgery. Is this normal?
Mild residual lameness can persist to 4 months, particularly in older dogs or those with significant muscle atrophy.
However, lameness at 4 months that is not showing week-over-week improvement warrants a veterinary assessment.
A radiograph will confirm bone healing status; physical examination will assess muscle mass and stifle range of motion.
My dog is limping on the opposite leg during TPLO recovery. What does that mean?
This raises concern for contralateral CCL disease. The opposite leg is bearing extra load during recovery and may have already been compromised.
A new limp on the opposite leg during recovery warrants veterinary evaluation, including assessment and radiographs of the contralateral stifle.
Can physiotherapy reduce long-term limping?
Yes, significantly. Rebuilding the atrophied quadriceps and hip extensor muscles through controlled hydrotherapy, cavaletti exercises, and progressive strength work reduces the compensatory gait patterns that produce chronic post-TPLO lameness.
Weight management is equally important -- every additional kilogram of body weight increases stifle load.
When is limping after TPLO an emergency?
Sudden complete non-weight bearing (holding the leg entirely off the ground) after a period of normal improvement is an emergency call. Same-day emergency veterinary contact is appropriate for this presentation.
Gradual worsening that does not resolve within 24 to 48 hours is a next-day call.

Arthrex TPLO Weight Chart Explained
Understand the Arthrex TPLO weight chart and how it guides post-op care for dogs after TPLO surgery.
After TPLO surgery, one of the most important questions owners and rehabilitation teams ask is: how much weight should my dog be putting on the operated leg right now?
The Arthrex TPLO weight chart provides a structured, week-by-week answer to that question, giving both surgeons and owners a shared reference point for tracking recovery progress.
Quick answer: The Arthrex TPLO weight chart tracks the percentage of body weight a dog bears on the operated leg at each recovery stage — from 0 to 10% in the first weeks to 100% by 8 to 12 weeks post-surgery.
Key takeaways
- The weight chart tracks weight-bearing percentage at each stage, from 0 to 10% in weeks 1 to 2 to 100% by weeks 8 to 12
- It is a rehabilitation monitoring tool, not a surgical planning tool: the rotation chart governs intraoperative correction; this tracks recovery
- Progression must be gradual: advancing too fast risks implant failure; too slow leads to atrophy and stiffness
- The chart integrates with clinical examination: 8-week radiographs, gait assessment, and muscle mass evaluation are considered alongside chart milestones
- Individual dogs vary: the chart provides population-level benchmarks; your surgeon's instructions take precedence
- The chart is used alongside the plate size and rotation charts: together they form the Arthrex TPLO system framework
What the weight chart is and what it is not
The Arthrex TPLO weight chart is a post-operative rehabilitation tool.
It shows recommended weight-bearing percentages at specific time points after surgery a reference guide that helps veterinarians, rehabilitation therapists, and owners track whether a dog's recovery is progressing appropriately.
It is not the same as the rotation chart (which guides intraoperative tibial rotation) or the plate size chart (which guides implant selection before surgery).
These three charts together form the Arthrex TPLO planning and monitoring system.
For the rotation chart guide, see Arthrex TPLO rotation chart explained. For the plate overview, see Arthrex TPLO plate overview and use.
Understanding the weight-bearing percentages
The chart uses percentage of body weight as its unit of measurement.
This is a more useful measure than time alone because it relates directly to the mechanical load placed on the healing osteotomy and implant.
0 to 10% weight-bearing (weeks 1 to 2): toe-touching and minimal contact only. The dog is not actively loading the leg during this phase. Bathroom trips on leash are permitted, but no sustained weight-bearing.
10 to 30% (weeks 2 to 4): the dog begins placing meaningful weight on the leg during slow leash walks. This corresponds to the short 5 to 10 minute leash walks prescribed at this stage. The healing osteotomy is starting to consolidate but is not yet ready for full load.
30 to 60% (weeks 4 to 8): progressive loading during longer walks, sit-to-stand exercises, and early rehabilitation activities. Most dogs are visibly improving in gait symmetry during this phase.
60 to 100% (weeks 8 to 12): full weight-bearing is approached and typically achieved after the radiographic recheck at week 8 confirms adequate osteotomy healing. Activity levels increase under veterinary guidance.
How to use the chart in practice
As a clinical benchmark
Surgeons use the weight chart to assess whether a dog is progressing as expected at each recheck visit.
A dog that is well below the expected weight-bearing percentage for their stage may have inadequate pain control, implant complications, or infection.
A dog exceeding the expected percentage may be at risk of mechanical overload if the bone has not yet consolidated enough to tolerate the load.
As an owner reference
Owners are not expected to measure exact weight-bearing percentages at home this requires force plate analysis or pressure-sensitive walkway equipment.
The chart provides a conceptual framework: early recovery shows only toe-touching; by weeks 4 to 6, the dog places meaningful weight during walks; by weeks 10 to 12, gait symmetry improves steadily.
What affects weight-bearing progress
Bone healing rate: younger dogs and smaller breeds typically consolidate the osteotomy faster than older or giant breed dogs.
Pain control: inadequate analgesia is the most common cause of delayed weight-bearing. A dog in pain will protect the operated leg regardless of how well the surgery went. Contact your surgeon if your dog is significantly below expected weight-bearing benchmarks.
Muscle atrophy: dogs that enter surgery with significant muscle atrophy from prolonged pre-surgical lameness progress more slowly and benefit most from structured rehabilitation.
Body weight: heavier dogs place more absolute load on the healing osteotomy at any given percentage. This is one reason weight management is emphasized throughout the TPLO recovery period.
Rehabilitation: dogs receiving structured rehabilitation (PROM, sit-to-stand, hydrotherapy) consistently achieve better weight-bearing progression than those managed with rest alone.
When the chart says one thing and your dog does another
The weight chart represents population-level expectations. Individual dogs routinely deviate from the expected timeline for reasons that are often identifiable and manageable.
If your dog is significantly under-progressing: contact your surgeon to rule out infection, implant problems, or inadequate pain management before assuming slow healing.
If your dog appears to be weight-bearing well ahead of schedule: this does not mean the osteotomy is healed faster than expected.
Radiographic confirmation at week 8 is still required regardless of how the dog looks clinically. Apparent early function does not mean the bone has consolidated enough to withstand full unrestricted activity.
For the full weight-bearing recovery timeline guide, see how soon can a dog walk after TPLO surgery.
For the rotation chart that is used alongside the weight chart in the Arthrex system, see Arthrex TPLO rotation chart explained.
For the plate size chart used in conjunction with both, see TPLO plate size chart explained.
Frequently asked questions
Is the Arthrex TPLO weight chart the same as a standard recovery timeline?
Not exactly. A recovery timeline tells you what activities to do and avoid at each stage.
The weight chart specifically tracks how much weight the dog is placing on the operated leg at each stage, expressed as a percentage of body weight.
The two are related but provide different information.
Can I measure my dog's weight-bearing at home?
Not precisely. Force plate and pressure-sensitive walkway systems that measure actual weight distribution require specialist veterinary equipment.
At home, you can observe whether the dog is toe-touching, placing the foot flat, and walking with increasing symmetry which approximates the chart's progression categories without exact percentages.
What if my dog refuses to use the leg at all two weeks after TPLO?
Non-weight-bearing at two weeks is a warning sign. TPLO Austin confirms that if your pet is not bearing weight within two weeks of surgery, contact your veterinarian.
The most common causes are inadequate pain control, infection, or implant positioning concerns all of which are addressable if caught early.
Do all TPLO surgeons use the Arthrex weight chart?
No. The Arthrex system is one of the two major TPLO implant systems in the US (alongside Synthes). Surgeons using Synthes implants use Synthes-specific planning tools.
Some surgeons use individualized rehabilitation protocols rather than system-specific charts. The underlying recovery milestones are similar regardless of which chart or system is used.
What happens at the 8-week recheck in terms of weight-bearing?
At the 8-week recheck, radiographs assess osteotomy healing. If healing is adequate, the surgeon approves increased activity typically 20 to 30 minute leash walks and the beginning of return-to-normal activity.
The weight chart at this point expects the dog to be approaching or achieving 100% weight-bearing on the operated leg.

What to Expect After TPLO Surgery in Dogs
Learn what to expect after TPLO surgery, including pain, swelling, healing time, and care tips for your dog’s smooth recovery.
TPLO recovery is a structured 8 to 12 week process. The surgery takes 1.5 to 2 hours; the recovery takes months.
Understanding what is normal at each stage allows owners to support recovery confidently, recognize complications early, and avoid mistakes that extend recovery or cause setbacks.
Quick answer: After TPLO surgery, expect 8 to 12 weeks of graduated activity restriction. Weeks 1 to 2: crate rest, short walks, e-collar on. Weeks 3 to 8: progressive walks and range-of-motion exercises. Weeks 8 to 12: confirm bone healing and resume normal activity. Full muscle recovery takes 6 months.
Key takeaways
- The 8 to 12 week bone healing period is non-negotiable: the plate holds the osteotomy until new bone consolidates; premature high-impact activity before radiographic healing can cause plate failure
- Weeks 1 and 2 are highest-risk for infection and wound complications: the incision is healing; activity and wound management must be strictly controlled
- Most dogs begin partial weight bearing within the first few days: early weight bearing maintains muscle mass and supports bone healing per TPLO Info
- The 2-week recheck, 6-week radiograph, and 12-week radiograph are essential milestones: each has a specific purpose; missing them risks missing early complications
- Full muscle recovery takes up to 6 months after bone healing is confirmed; bone union and functional recovery are not the same endpoint
- The e-collar must stay on for 10 to 14 days without exception: licking is the leading owner-controlled cause of TPLO surgical site infection
Immediately after surgery: days 1 to 3
Coming home
Dogs are typically discharged 24 to 48 hours after TPLO surgery, or sometimes the same day at facilities with same-day discharge protocols.
The dog will be sedated, disoriented from anesthesia, and may have bandaging on the surgical leg.
Expect:
- Groggy, disoriented behavior for 12 to 24 hours from anesthesia
- Some whining or restlessness (normal -- from anesthesia, not necessarily pain)
- Refusal to bear weight on the operated leg
- Mild to moderate swelling around the incision, peaking at days 2 to 3
Pain management
Give prescribed medications on the exact schedule provided. Typical medications include NSAIDs (meloxicam, carprofen, or similar) and gabapentin. Give NSAIDs with food to reduce gastric irritation.
TPLO Info confirms: dogs may experience slight discomfort from surgical inflammation in the days following surgery; this should be managed with appropriate pain medications given on schedule.
Confinement
Strict crate rest or confinement in a small, non-slippery room. No stairs, no jumping, no access to furniture. Leash walks outdoors for bathroom purposes only, 3 to 5 minutes, multiple times daily.
Weeks 1 to 2: incision healing phase
This is the highest-risk period for wound complications and infection.
Incision care:
- E-collar must be on at all times except supervised eating and drinking
- Keep the incision dry -- no baths, no wet grass walks
- Inspect the incision daily for spreading redness, cloudy or malodorous discharge, or wound dehiscence
- Normal: a small amount of clear serum discharge in the first 2 to 3 days; mild redness at the incision line fading from day 5 onward
- Abnormal: spreading redness, cloudy discharge, increasing warmth, or wound edges separating -- contact your vet immediately
Activity:
- Leash walks only, 5 minutes maximum, multiple times daily
- No running, jumping, stairs, or playing with other pets
- No unsupervised time without the e-collar
Weight bearing:
- Many dogs begin toe-touching within the first few days
- Some dogs refuse weight bearing for the full two weeks -- this is also normal
- Encouraging gentle, slow walking on a leash helps maintain muscle mass
2-week recheck:SustainableVet.org confirms: the 2-week visit confirms incision healing, removes sutures or staples if healing is complete, and reviews pain management and early mobility status.
Weeks 3 to 6: progressive walking phase
The incision is closed; the focus shifts to controlled progressive activity increase and gentle range of motion.
Activity:
- Increase leash walk duration gradually -- TPLO Info recommends increasing by up to 5 minutes per week from the week 2 baseline
- No off-leash activity, no running, no jumping, no stairs without a ramp
- No playing with other pets
Range-of-motion exercises:
- Passive range-of-motion (PROM) exercises can begin in most dogs at weeks 2 to 4 if the vet approves
- Gentle flexion and extension of the stifle for 5 to 10 repetitions, 2 to 3 times daily
- Supports joint flexibility and prevents stiffness during the bone healing period
Weight bearing:
- By weeks 3 to 4, most dogs are consistently bearing weight on the operated leg
- Occasional toe-touching or three-legged walking during activity is still normal
What to watch for:
- Lameness that worsens after a period of improvement (trajectory reversal)
- New swelling at the plate site, separate from the healed incision
- Any discharge from the healed wound area
Weeks 6 to 8: early consolidation phase
6-week radiograph (critical milestone):SustainableVet.org confirms: the 6-week visit includes follow-up radiographs to evaluate bone alignment and early plate stability; if healing looks good, limited physical therapy or short walks may begin.
If the radiograph shows good progression of bone healing, activity is increased. If healing is delayed, restrictions continue with a re-radiograph at 8 weeks.
Activity (if healing is confirmed):
- Leash walks increasing to 15 to 20 minutes twice daily
- Rehabilitation exercises as directed
- Hydrotherapy (if available) is an excellent low-impact option for muscle building
Weeks 8 to 12: bone consolidation and return to activity
Follow-up radiograph at 8 to 10 weeks:Medcovet confirms: a follow-up radiograph is commonly performed at weeks 8 to 10 to assess bone healing; if healing is good, the vet may approve a gradual increase in activity.
12-week visit (major milestone):SustainableVet.org confirms: the 12-week visit includes final radiographs to confirm bone fusion and plate integrity; the vet may lift most activity restrictions at this stage.
Activity (if healing confirmed at 12 weeks):
- Progressive return to normal activity
- Running, jumping, and play can gradually resume over weeks 12 to 16
- Supervised play and controlled activity continue until full muscle recovery
Animal Outpatient Surgery confirms: full muscle recovery takes up to 6 months to restore full strength and coordination in the operated leg.
Medications and supplements
NSAIDs: given for 2 to 4 weeks post-surgery or as directed. Never exceed the prescribed dose; never use human NSAIDs (ibuprofen, aspirin) -- they are toxic to dogs.
Gabapentin: helps with pain and anxiety in the early recovery period; typically tapered off after 2 to 4 weeks.
Joint supplements: glucosamine and omega-3 fatty acids are commonly recommended for long-term joint health. Starting them at surgery is reasonable; discuss with your vet.
Signs requiring immediate veterinary contact
At any stage of recovery, contact your vet immediately if you see:
- Spreading redness or warmth at the incision or plate site
- Cloudy, yellow, green, or malodorous discharge from the wound
- Wound edges separating
- Severe worsening of lameness
- Fever, lethargy, or loss of appetite beyond the first 2 to 3 days
- Any draining tract opening near the surgical site

Frequently asked questions
When will my dog be back to normal after TPLO?
Bone healing is typically confirmed by radiograph at 8 to 12 weeks. Most activity restrictions are lifted at the 12-week mark.
Full muscle recovery and functional normalization takes up to 6 months from surgery.
TPLO has a high success rate (more than 90%) and most dogs return to their pre-injury activity level after full recovery.
My dog is not using the leg at all after surgery. Is that normal?
Some dogs refuse to bear weight for the full first 2 weeks. This is within normal range.
If the dog was bearing some weight and has now stopped completely after day 5, contact your vet to rule out a complication.
PROM exercises and gentle encouraged walking help prompt early weight bearing.
Can my dog go up stairs during recovery?
Not during weeks 1 to 6. Stairs generate impact and torsion on the healing osteotomy. Carry small dogs over stairs or use a ramp.
Larger dogs may need a sling or harness to assist navigating a small number of essential steps.
When can my dog swim or do hydrotherapy?
Hydrotherapy (underwater treadmill or controlled pool swimming) typically begins after incision healing is confirmed at 2 weeks. Check with your vet.
Swimming in open water (lakes, rivers) is not appropriate until the vet explicitly clears the dog, typically after the 12-week radiograph.
When should I be concerned about my dog's pain during recovery?
Increasing pain after initial improvement -- the dog more lame or more distressed today than yesterday -- is the key warning sign. Normal recovery pain decreases progressively.
Worsening pain warrants veterinary assessment to rule out infection, implant complication, or late meniscal injury.

TPLO Plate Removal Cost Explained
Learn about TPLO plate removal cost, factors affecting pricing, and what to expect during recovery after surgery.
When your dog undergoes a TPLO surgery, you may wonder about the cost of removing the TPLO plate later. TPLO plate removal cost can vary widely depending on several factors. Understanding these costs helps you prepare financially and know what to expect for your pet's care.
This article explains what TPLO plate removal involves, the typical price range, factors influencing cost, and recovery tips. You will learn how to plan for this procedure and ensure your dog’s health and comfort throughout the process.
What is TPLO plate removal surgery?
TPLO plate removal surgery is a procedure to take out the metal plate used in Tibial Plateau Leveling Osteotomy (TPLO) surgery. This plate stabilizes your dog’s knee after a ligament injury. Sometimes, removal is needed due to pain, infection, or after healing.
Not all dogs require plate removal. Your vet will decide based on symptoms and X-rays. The surgery involves anesthesia, incision, plate removal, and closing the site.
- Purpose of removal: The plate may be removed if it causes discomfort, infection, or irritation to surrounding tissues, improving your dog’s comfort.
- Surgical process: The vet reopens the original incision site to carefully remove the plate and screws, minimizing damage to bone and soft tissue.
- Timing considerations: Removal usually happens months after the initial TPLO once the bone has fully healed and is stable without the plate.
- Risks involved: Like any surgery, risks include infection, anesthesia complications, or delayed healing, which your vet will discuss beforehand.
Understanding the surgery helps you prepare for the cost and recovery your dog will face.

What factors influence TPLO plate removal cost?
Several factors affect the final cost of TPLO plate removal. These include your dog’s size, health, and the complexity of the surgery. Understanding these helps you anticipate expenses and discuss options with your vet.
Each case is unique, so costs can vary even within the same clinic.
- Dog’s size and weight: Larger dogs may require longer surgery time and more anesthesia, increasing overall cost compared to smaller dogs.
- Complications during surgery: If the plate is difficult to remove due to bone overgrowth or infection, surgery time and cost may increase.
- Pre-existing health conditions: Dogs with other health issues may need additional tests or monitoring, adding to the price.
- Post-operative care needs: Extended pain management, physical therapy, or wound care can raise the total cost after surgery.
Discuss these factors with your vet to understand how they apply to your dog’s situation.
Is TPLO plate removal always necessary?
TPLO plate removal is not always required. Many dogs live comfortably with the plate permanently. Your vet will recommend removal only if there are specific problems like pain or infection.
Knowing when removal is needed helps you avoid unnecessary surgery and costs.
- No symptoms present: If your dog shows no discomfort or mobility issues, plate removal is usually not recommended.
- Signs of irritation: Persistent swelling, pain, or lameness near the plate may indicate removal is needed.
- Infection risk: If the plate site becomes infected and does not respond to antibiotics, removal may be necessary to heal.
- Bone healing status: Removal is only done after the bone has fully healed and is stable without the plate.
Regular check-ups help your vet decide if plate removal is the best option for your dog.
What should I expect during recovery from TPLO plate removal?
Recovery from TPLO plate removal typically takes 4 to 8 weeks. Your dog will need rest, limited activity, and pain management. Following your vet’s instructions is key to a smooth recovery.
Proper care reduces risks of complications and helps your dog return to normal activity safely.
- Restricted activity: Limit running, jumping, and stairs for several weeks to allow the surgical site to heal properly.
- Pain control: Your vet will prescribe pain medications to keep your dog comfortable during recovery.
- Wound care: Keep the incision clean and dry, and watch for signs of infection like redness or discharge.
- Follow-up visits: Regular check-ups ensure healing is on track and allow your vet to adjust care as needed.
Patience and careful monitoring help your dog heal well after plate removal surgery.
How can I prepare financially for TPLO plate removal?
Preparing financially for TPLO plate removal involves understanding costs, checking pet insurance, and discussing payment options with your vet. Planning ahead reduces stress when your dog needs surgery.
Being proactive helps you provide the best care without unexpected financial burden.
- Get a detailed estimate: Ask your vet for a full cost breakdown including surgery, medications, and follow-ups before scheduling.
- Check pet insurance: Review your policy to see if TPLO plate removal or related care is covered to offset expenses.
- Set aside savings: Having an emergency fund for pet health helps cover unexpected costs without delay.
- Discuss payment plans: Many clinics offer financing or payment plans to spread out the cost of surgery over time.
Financial readiness ensures you can focus on your dog’s recovery without worry.
What are the risks and complications of TPLO plate removal?
Like any surgery, TPLO plate removal carries risks such as infection, anesthesia reactions, or delayed healing. Knowing these helps you watch for problems and act quickly if needed.
Your vet will explain risks and how to minimize them before surgery.
- Infection risk: The surgical site can become infected, requiring antibiotics or further treatment to heal properly.
- Anesthesia complications: Dogs may react to anesthesia with breathing or heart issues, though this is rare with proper monitoring.
- Delayed bone healing: Removing the plate too early or surgical trauma can slow bone healing, causing pain or instability.
- Soft tissue damage: Nearby muscles or nerves may be injured during surgery, leading to temporary or permanent issues.
Careful surgical technique and post-op monitoring reduce these risks significantly.
