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 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.

TPLO produces predominantly positive long-term effects in most dogs, but it also produces a predictable set of changes that owners should understand and manage proactively.

Most of these effects are manageable with appropriate care. Knowing what to expect prevents owners from being surprised by normal post-TPLO findings and helps them recognize when a change requires veterinary attention.

Quick answer: The 13 key long-term effects of TPLO surgery: improved joint stability, progressive osteoarthritis, muscle atrophy, morning stiffness, cold weather sensitivity, scar tissue formation, patellar tendon thickening, permanent implant in situ, contralateral CCL rupture risk, late implant complications, behavioral changes from chronic pain, weight management challenges, and long-term monitoring requirements.

Key takeaways

• Improved joint stability is the intended and most common long-term effect: for 90 to 95% of dogs, TPLO eliminates CCL-related instability and restores near-normal function
• Progressive osteoarthritis develops in all CCL-affected stifles regardless of surgical technique: TPLO slows OA progression but does not stop it; long-term OA management is a universal requirement
• Muscle atrophy is common in the operated leg throughout recovery; the thigh may remain visibly smaller than the contralateral side for months if rehabilitation is inadequate
• Contralateral CCL rupture risk is high: SustainableVet.org confirms up to a 50% chance of tearing the opposite CCL within a few years; the same degenerative process affects both stifles
• The TPLO plate and screws are permanent in the vast majority of cases: removal is only performed when complications arise; routine plate removal is not standard practice
• Weight management is the most impactful long-term owner-controlled variable: excess weight accelerates OA progression; maintaining ideal body condition is the primary long-term prevention strategy

The 13 long-term effects

1. Improved joint stability and mobility

The primary intended effect. The osteotomy and plate fixation permanently change the tibial plateau geometry, eliminating the cranial tibial thrust that caused instability.

For 90 to 95% of dogs, this produces lasting functional improvement: return to normal gait, ability to run and play, and freedom from the pain of unstable joint loading.

SustainableVet.org confirms: over 90% of dogs regain full limb function within a year; with proper care, many dogs remain active for 8 to 10 years after surgery.

2. Progressive osteoarthritis

The most universal long-term challenge. CCL disease initiates an arthritis process in the stifle that continues regardless of surgical outcome.

TPLO reduces the rate of progression and the severity of clinical signs compared to other treatment options, but OA continues.

Clinical signs of progressing OA emerge gradually over months and years: stiffness after rest, reluctance to run, difficulty climbing, and behavioral changes associated with chronic low-grade pain.

Management: weight management, omega-3 fatty acids, glucosamine and chondroitin, NSAIDs for flares, hydrotherapy, physiotherapy.

3. Muscle atrophy and asymmetry

The operated leg loses muscle mass rapidly during the restriction period and slowly rebuilds during rehabilitation. Full recovery of muscle symmetry takes 4 to 6 months in most dogs.

In some dogs -- particularly those with inadequate rehabilitation or ongoing joint pain -- visible thigh circumference asymmetry persists long-term.

Vetplayas confirms: due to reduced use during recovery and altered movement patterns post-surgery, muscles around the operated leg may weaken and shrink.

4. Morning stiffness

Morning stiffness -- the dog rises from sleep stiffly and walks awkwardly for the first few minutes before loosening up -- is one of the most common long-term effects of post-TPLO OA.

It typically develops months to years after surgery and gradually worsens as the dog ages.

This stiffness should not be confused with acute lameness. It consistently improves within 5 to 10 minutes of movement.

If it does not improve, or if the dog refuses to bear weight on waking, contact your vet.

5. Cold weather sensitivity

Dogs with OA in the operated stifle commonly show increased stiffness and lameness during cold weather or when barometric pressure changes.

This reflects the sensitivity of arthritic joints to temperature and pressure changes -- the same phenomenon seen in human arthritis.

Management: NSAIDs or joint supplements maintained year-round; warming the dog's sleeping area; a brief gentle walk before expecting full function in cold conditions.

6. Scar tissue formation

The surgical dissection and bone healing produce scar tissue in and around the stifle. This fibrous tissue generally has a beneficial stabilizing effect, contributing to long-term joint stability.

In some dogs, however, periarticular fibrosis restricts range of motion and causes stiffness that persists long after bone healing is complete.

Regular low-impact exercise and physiotherapy help maintain range of motion and prevent excessive fibrous tissue restriction.

7. Patellar tendon thickening

Fibrous thickening of the patellar tendon is a recognized long-term change after TPLO. It is typically subclinical -- detected on palpation at follow-up examinations but not producing clinical lameness.

In a small number of dogs, it contributes to reduced range of motion.

8. Permanent implant in situ

The TPLO plate and screws are designed to remain in place for life. In the vast majority of dogs, the implant is never removed and causes no long-term problems.

SustainableVet.org confirms: these implants are meant to stay in place permanently. In rare cases, some dogs may develop infections around the implant or experience loosening of the hardware over time.

The plate is palpable under the skin on the medial tibial surface. This is normal and not a complication.

9. Contralateral CCL rupture

The degenerative process that caused one CCL to rupture typically affects both stifles.

SustainableVet.org confirms dogs have up to a 50% chance of tearing the CCL in the opposite knee within a few years.

RCVS confirms approximately 50% of dogs develop CCL disease in the other hind limb.

This is not a complication of TPLO -- it is the natural history of bilateral CCL disease.

Monitoring the contralateral stifle for early signs of instability, effusion, or lameness is appropriate in all TPLO dogs.

10. Late implant-associated complications

Implant-related complications -- loosening, late infection from hematogenous seeding, or implant irritation -- can occur years after the original surgery. These are uncommon but recognized long-term effects.

Signs: new lameness focused at the plate site, warmth or swelling over the plate, a new draining tract in previously healed skin. Any of these warrants prompt veterinary assessment.

11. Behavioral changes

Chronic joint pain from progressive OA, late meniscal injury, or implant irritation can produce subtle behavioral changes: reduced engagement in play, reluctance to walk, increased irritability, or reduced stair use.

These changes are often attributed to aging but may reflect treatable pain.

Annual or semi-annual pain assessments, including use of validated canine pain scales (Canine Brief Pain Inventory, Helsinki Chronic Pain Index), help detect behavioral pain signs before they become severe.

12. Weight management challenges

Activity restriction during recovery predisposes many dogs to weight gain. Excess weight gained during the 8 to 12 week restriction period is then carried on the healing joint for the following months.

Long-term obesity accelerates OA progression and is the most modifiable risk factor for long-term joint health.

Medcovet confirms: because activity is restricted, veterinary teams may recommend reducing food intake by about 30% during recovery to prevent weight gain and extra strain on the knee joint.

13. Long-term monitoring and supplement requirements

TPLO dogs benefit from long-term monitoring (every 6 to 12 months after full recovery) to assess:

• Arthritis progression radiographically and clinically
• Body condition score and weight
• Contralateral stifle stability
• Implant integrity (radiographs every 1 to 2 years in some protocols)

Joint supplements (omega-3 fatty acids at anti-inflammatory doses; glucosamine and chondroitin) and ongoing weight management are the primary preventive interventions for the long-term joint changes that TPLO does not prevent.

For the signs that require attention, see signs of TPLO failure in dogs. For the failure rate overview, see TPLO failure rate in dogs.

Frequently asked questions

Will my dog develop arthritis even if the TPLO was successful?

Yes. All CCL-affected stifles develop progressive osteoarthritis regardless of surgical technique or outcome.

TPLO reduces the rate of progression and the severity of clinical signs compared to non-surgical management and lateral suture repair.

The goal of TPLO is not to prevent OA but to minimize it while restoring function.

How long will the TPLO plate last?

The plate is designed to be permanent. Published long-term follow-up data at 6.8 years shows 90.4% of dogs with good to excellent results -- with the plate in place.

Plate complications requiring removal occur in 3.5 to 7.5% of cases.

My dog had TPLO 2 years ago and is now limping. Is this related to the surgery?

Possibly. Two-year post-TPLO lameness most commonly results from progressive OA, late meniscal tear, late implant-associated infection (hematogenous seeding), or contralateral CCL disease.

A veterinary examination and radiographs of both stifles will identify the cause and guide treatment.

Does the opposite leg always need TPLO as well?

Not necessarily and not always at the same time. RCVS confirms approximately 50% of dogs develop CCL disease in the opposite hind limb.

When and whether the second stifle requires surgery depends on whether the second CCL has ruptured or become significantly unstable. Annual monitoring of the contralateral stifle is appropriate.

Can TPLO dogs still live active lives long-term?

Yes. Most do. SustainableVet.org confirms that with proper care, many dogs remain active for 8 to 10 years after surgery.

The keys are weight management, regular low-impact exercise, joint supplements, and addressing pain or complications promptly.

Physical therapy after TPLO begins on day one -- not after the bone heals. The question is not whether to start, but which type is appropriate at each stage.

Early rehabilitation is about pain management and encouraging weight bearing. Later rehabilitation is about restoring muscle mass, range of motion, and functional strength.

The timing for each phase is defined by healing biology, not by how the dog appears to feel.

Quick answer: Physical therapy begins on day 1 with leash walks and cold therapy. Passive range-of-motion exercises start at days 3 to 5. Hydrotherapy begins at weeks 2 to 3. Strengthening increases from weeks 4 to 8. Plans complete by weeks 8 to 12; full recovery takes 4 to 6 months after TPLO surgery.

Key takeaways

• Leash walking begins within 24 hours of surgery: TPLO Info confirms short 5-minute walks multiple times daily from day 1; early weight bearing maintains muscle mass and bone healing
• Passive range-of-motion exercises start at days 3 to 5: gentle manual flexion and extension of the stifle maintains joint mobility during restricted activity
• Hydrotherapy can begin around weeks 2 to 3 after incision healing is confirmed; underwater treadmill provides resistance and buoyancy simultaneously
• Professional rehabilitation offers advantages over at-home protocols: certified therapists provide therapeutic laser, TENS, underwater treadmill, and individualized monitoring
• Strengthening exercises begin around weeks 3 to 4 when the dog consistently bears weight; cavaletti poles, weight-shifting, and balance work rebuild lost muscle
• Free running and high-impact activities resume only after radiographic bone healing confirmation at weeks 8 to 12; earlier return risks osteotomy failure

Phase 1: immediate post-surgical period (days 1 to 14)

What begins immediately

Leash walking: begins within 24 hours of surgery. TPLO Info confirms short 5-minute leash walks multiple times daily from day one. These walks are bathroom trips only in the first week -- not exercise walks. The goal is to maintain the neural stimulus for weight bearing and to prevent the complete disuse that leads to rapid muscle atrophy.

Veterinary Partner VIN confirms: Phase 1 begins immediately after surgery; slow, controlled leash walks 3 to 4 times daily for 5 to 10 minutes are the primary activity.

Cold therapy (icing): ice applied to the incision site for 10 to 15 minutes after each walk during the first 3 to 5 days. TPLO Info recommends icing the incision directly for the first 3 to 5 days post-surgery. Cold therapy reduces local inflammation and pain, making the dog more comfortable and more likely to bear weight.

Edmonton Veterinary TPLO protocol confirms: time physical therapy exercises approximately 30 minutes after pain medications are given so the dog is most comfortable during exercise.

Passive range-of-motion exercises (days 3 to 5)

PROM exercises are gentle manual flexion and extension of the stifle joint. SustainableVet.org confirms: gentle passive exercises usually start within 3 to 5 days post-surgery.

How to perform PROM:

• Hold the thigh and lower leg, not the joint itself
• Slowly flex the stifle toward the chest (as far as comfortable without resistance)
• Slowly extend the stifle toward straight
• 5 to 10 repetitions, 2 to 3 times daily
• Never force the range -- stop at the point of resistance or discomfort

PROM maintains joint cartilage health, prevents fibrous tissue formation in the joint, and maintains range of motion during the period when the dog is resting.

Phase 2: early rehabilitation (weeks 2 to 4)

What begins at the 2-week recheck

The 2-week recheck confirms incision healing and reviews early recovery. If healing is proceeding normally, Phase 2 activities begin.

Increased leash walk duration: TPLO Info recommends increasing walk duration by up to 5 minutes per week from the 2-week baseline. Vetplayas confirms: by week 2, controlled leash walks should be extended to promote muscle strength and flexibility.

Hydrotherapy: SustainableVet.org and the Vetplayas recovery guide both confirm hydrotherapy can begin around week 2 to 3, once the incision is healed. Underwater treadmill therapy provides three simultaneous benefits:

• Buoyancy reduces joint loading while still requiring weight bearing
• Water resistance builds muscle without impact
• Warmth promotes circulation and reduces stiffness

Professional hydrotherapy (certified facility with underwater treadmill) is preferable to open-water swimming in the early phase -- controlled depth and therapist supervision improve safety.

Balance training (from week 3 to 4): TPLO Info confirms that once the dog is consistently bearing weight on the operated leg (typically around weeks 3 to 4), weight-shifting exercises can begin. Stand the dog on a non-slip surface and gently push the hindquarters from side to side -- the dog responds by shifting weight to maintain balance, which activates the hip stabilizers.

Phase 3: progressive strengthening (weeks 4 to 8)

Core strengthening and higher-level exercises

Veterinary Partner VIN confirms: Phase 2 (which overlaps with what most owners call weeks 3 to 8) involves core strengthening once sufficient basic strength is achieved.

Activities that begin in weeks 4 to 8 (vet-directed):

• Cavaletti poles: slow stepping over low poles placed on the ground; encourages deliberate limb placement and hip flexion
• Hill walking: gentle inclines on a leash (begin by week 6 in most protocols)
• Sit-to-stand exercises: transitions from sitting to standing strengthen hip extensors
• Balance board or wobble board exercises: builds proprioception and stabilizer strength

WM-Referrals TPLO physiotherapy protocol confirms: start hydrotherapy, cavaletti poles, and balance board work at week 6; progress to 30 to 40 minute walks by this phase.

6-week radiograph checkpoint: activity level in Phase 3 is calibrated against radiographic findings at the 6-week visit. If bone healing is progressing well, activities increase as above. If healing is delayed, Phase 3 activities are deferred.

Phase 4: return to function (weeks 8 to 12 and beyond)

Radiographic confirmation at 8 to 12 weeks

SustainableVet.org confirms: most structured plans complete within 8 to 12 weeks. By 4 to 6 months, most dogs regain full mobility including running and playing.

After the 12-week radiograph confirms bone healing:

• Progressive jogging on leash
• Longer off-leash exploration in controlled environments
• Return to normal activity for most dogs
• Athletes and working dogs continue structured rehab for 4 to 6 months

Professional rehabilitation vs. at-home protocols

When professional rehab is recommended

TPLO Info confirms: ideally every dog would follow up with a rehabilitation therapist so a doctor can develop an individualized protocol. Professional rehabilitation is particularly beneficial when:

• The dog is slow to bear weight
• Significant muscle atrophy is present at the 6-week recheck
• The dog is a working dog, sports dog, or agility competitor
• Progress has stalled at any phase of recovery

What professionals offer

Certified canine rehabilitation therapists (CCRPs) provide:

• Therapeutic laser (reduces inflammation, promotes tissue healing)
• Transcutaneous electrical nerve stimulation (TENS) for pain management
• Controlled underwater treadmill protocols
• Individualized exercise prescription based on daily assessment
• Early detection of complications (inappropriate gait patterns, asymmetric muscle development)

At-home protocols

At-home rehabilitation following the vet's guidelines is appropriate for most dogs.

The core elements -- short leash walks, PROM exercises, cold therapy, gradual activity increase, and balance work -- are all achievable at home with proper instruction.

For the recovery timeline overview, see what to expect after TPLO surgery in dogs. For PROM exercises specifically, see PROM exercises for dogs after TPLO surgery.

For range-of-motion exercises, see TPLO range-of-motion exercises for dogs. For rehab exercise detail, see TPLO rehab exercises for dogs.

Frequently asked questions

Can physical therapy start before the incision heals?

Yes -- the early elements (leash walking, cold therapy, and PROM exercises) begin before the incision is fully healed, typically from day 1 to 5 onward.

Hydrotherapy and balance work require incision healing confirmation, typically at the 2-week recheck.

Is professional physical therapy necessary for TPLO recovery?

Not strictly necessary for all dogs, but beneficial for those recovering slowly, those with significant muscle atrophy, and working or sport dogs. At-home protocols following vet instructions are appropriate for most dogs.

Professional rehab adds precision and advanced modalities.

How often should my dog have hydrotherapy sessions?

Typically 1 to 3 times per week during the active rehabilitation phase (weeks 2 to 8). Frequency depends on the dog's response, transportation constraints, and cost.

Each session's therapeutic benefit persists for several days, so daily hydrotherapy is not required.

What if my dog refuses to use the leg despite physical therapy?

Persistent non-weight-bearing beyond 3 to 4 weeks warrants veterinary investigation. Possible causes include inadequate pain control, implant complication, late meniscal tear, or infection.

Physical therapy cannot proceed normally until the underlying cause of non-weight-bearing is addressed.

Can I use a swimming pool at home for hydrotherapy?

Only with vet guidance and with the dog supervised at all times. Open water swimming is less controlled than an underwater treadmill.

Risks include the dog launching themselves off the pool edge (impact on landing), inability to control depth, and water contamination of the incision if not fully healed.

The Arthrex TPLO plate is a specialized orthopedic implant designed to stabilize the tibia after a tibial plateau leveling osteotomy (TPLO) surgery in dogs. TPLO surgery is a common procedure to treat cranial cruciate ligament (CCL) rupture, which causes lameness and pain in dogs. Understanding the Arthrex TPLO plate helps pet owners and veterinarians appreciate how this device supports bone healing and restores limb function.

This article explains what the Arthrex TPLO plate is, how it is used during surgery, its design features, and the benefits it offers. You will learn about the surgical technique, implant materials, and postoperative care to ensure the best outcomes for dogs undergoing TPLO surgery.

What is the Arthrex TPLO plate?

The Arthrex TPLO plate is a metal implant used to fix the tibia after cutting and rotating the bone during TPLO surgery. It holds the bone segments securely to allow proper healing and restore normal joint mechanics. The plate is contoured to fit the shape of the canine tibia and is available in various sizes to match different dog breeds and sizes.

The plate works together with locking screws that provide stable fixation without compressing the bone excessively. This design helps reduce complications and promotes faster recovery.

• Purpose of the plate: It stabilizes the tibia after osteotomy, maintaining the new bone angle to prevent joint instability and lameness.
• Material composition: Made from medical-grade stainless steel or titanium, ensuring strength, biocompatibility, and corrosion resistance.
• Plate design: Anatomically contoured to match the tibial shape, minimizing soft tissue irritation and improving fit.
• Locking screw system: Uses locking screws that lock into the plate, providing angular stability and reducing screw loosening risks.

These features make the Arthrex TPLO plate a reliable choice for TPLO surgeries in veterinary orthopedics.

How is the Arthrex TPLO plate used in surgery?

During TPLO surgery, the surgeon makes a curved cut in the tibia and rotates the bone segment to change the slope of the tibial plateau. The Arthrex TPLO plate is then applied to hold the bone in its new position. Proper placement and fixation are critical for successful healing and restoring limb function.

The surgical steps include precise measurement, plate selection, and screw placement to ensure stability and avoid complications.

• Osteotomy procedure: The tibia is cut using a saw guided by a jig to create a controlled curved osteotomy.
• Plate positioning: The Arthrex TPLO plate is aligned over the osteotomy site to match the bone contour and rotated segment.
• Screw insertion: Locking screws are placed through the plate holes into the bone, securing the plate firmly.
• Verification of stability: The surgeon checks the fixation and limb alignment before closing the surgical site.

Following these steps ensures the plate supports the bone during healing and helps the dog regain normal limb use.

What are the advantages of using the Arthrex TPLO plate?

The Arthrex TPLO plate offers several benefits compared to traditional fixation methods. Its design and materials improve surgical outcomes and reduce postoperative complications. These advantages contribute to faster recovery and better function for dogs after TPLO surgery.

Understanding these benefits helps veterinarians choose the best implant for their patients.

• Enhanced stability: Locking screw technology provides rigid fixation, reducing micromotion and promoting bone healing.
• Reduced soft tissue damage: Anatomical contouring minimizes irritation and inflammation around the implant site.
• Corrosion resistance: High-quality materials prevent implant degradation and inflammatory reactions over time.
• Versatility in sizes: Multiple plate sizes accommodate different dog breeds, ensuring proper fit and function.

These features make the Arthrex TPLO plate a preferred choice for many veterinary surgeons performing TPLO surgeries.

What materials are used in the Arthrex TPLO plate?

The Arthrex TPLO plate is manufactured from biocompatible metals that provide strength and durability while minimizing adverse tissue reactions. The choice of materials affects the plate’s performance and long-term safety.

Knowing the materials helps veterinarians and pet owners understand implant behavior inside the body.

• Stainless steel: Commonly used for its strength, corrosion resistance, and affordability in orthopedic implants.
• Titanium alloy: Offers excellent biocompatibility, lighter weight, and reduced risk of allergic reactions.
• Surface finish: Smooth, polished surfaces reduce tissue irritation and bacterial adhesion risks.
• Radiopacity: Materials allow clear X-ray visualization to monitor implant position during follow-up.

These material properties ensure the Arthrex TPLO plate performs well during the healing process and remains safe long term.

How does the Arthrex TPLO plate support postoperative recovery?

Postoperative care is essential for successful healing after TPLO surgery using the Arthrex TPLO plate. The implant provides stable fixation, but proper management of the dog’s activity and monitoring are critical to prevent complications.

Understanding the role of the plate in recovery helps owners follow veterinary instructions effectively.

• Early weight bearing: Stable fixation allows controlled limb use soon after surgery, promoting muscle strength and joint mobility.
• Reduced risk of implant failure: Locking screws and plate design minimize loosening or breakage during recovery.
• Radiographic monitoring: Regular X-rays check bone healing and implant position to detect issues early.
• Physical therapy support: Rehabilitation exercises complement implant stability to restore normal gait and function.

Following these guidelines helps dogs recover faster and return to normal activity safely.

What complications can occur with the Arthrex TPLO plate?

While the Arthrex TPLO plate is designed to reduce complications, some risks remain. Awareness of potential problems helps veterinarians and owners recognize signs early and take action.

Most complications relate to surgical technique, implant placement, or postoperative care.

• Infection risk: Surgical site infections can occur, requiring antibiotics or implant removal in severe cases.
• Implant loosening: Poor screw fixation or excessive activity may cause the plate to loosen, affecting stability.
• Delayed bone healing: Factors like poor blood supply or infection can slow osteotomy healing despite stable fixation.
• Soft tissue irritation: Improper plate positioning may cause discomfort or swelling around the implant.

Close follow-up and adherence to postoperative instructions minimize these risks and improve outcomes.

Conclusion

The Arthrex TPLO plate is a vital implant in veterinary orthopedics for treating cranial cruciate ligament injuries in dogs. Its specialized design and locking screw system provide stable fixation, promote bone healing, and support early recovery.

Understanding the plate’s features, surgical use, and postoperative care helps pet owners and veterinarians ensure the best results after TPLO surgery. Proper implant selection and management reduce complications and help dogs regain normal limb function safely.

What sizes does the Arthrex TPLO plate come in?

The Arthrex TPLO plate is available in multiple sizes ranging from small to large to fit different dog breeds and tibial dimensions accurately.

Can the Arthrex TPLO plate be removed after healing?

Implant removal is not routinely required but may be performed if the dog experiences irritation, infection, or implant-related complications after bone healing.

How long does it take for the bone to heal with the Arthrex TPLO plate?

Bone healing typically takes 8 to 12 weeks, depending on the dog's age, health, and postoperative care quality.

Is the Arthrex TPLO plate MRI compatible?

Plates made from titanium alloys are generally MRI compatible, while stainless steel plates may cause artifacts or interference during imaging.

What postoperative care is recommended after TPLO surgery with this plate?

Recommended care includes restricted activity, pain management, physical therapy, and regular veterinary check-ups with radiographic monitoring to ensure proper healing.

Bruising after TPLO surgery in dogs is a common concern for many pet owners. TPLO, or Tibial Plateau Leveling Osteotomy, is a surgical procedure to stabilize a dog's knee after a cruciate ligament injury. After surgery, owners often notice bruising around the incision site or leg, which can be alarming.

This article explains why bruising happens after TPLO surgery, how to care for your dog during recovery, and when to contact your veterinarian. Understanding bruising helps you support your dog's healing process effectively.

Why Does Bruising Occur After TPLO Surgery in Dogs?

Bruising happens when blood vessels under the skin break and leak blood into surrounding tissues. After TPLO surgery, bruising is usually due to the trauma of surgery and tissue manipulation. The surgical area may show discoloration as part of normal healing.

It is important to recognize that some bruising is expected, but excessive or worsening bruising may indicate complications. Knowing the causes helps you monitor your dog’s recovery closely.

• Surgical trauma: The cutting and repositioning of bone and soft tissue during TPLO can cause small blood vessels to rupture, leading to bruising around the surgical site.
• Inflammation response: The body’s natural healing process causes inflammation, which can increase blood flow and cause visible bruising and swelling near the incision.
• Blood thinning medications: If your dog is on medications like aspirin or NSAIDs, these can increase bruising risk by affecting clotting mechanisms.
• Movement after surgery: Excessive activity or pressure on the leg soon after surgery can worsen bruising by disrupting healing tissues and blood vessels.

Understanding these causes helps you differentiate normal bruising from signs of complications that need veterinary attention.

What Does Normal Bruising Look Like After TPLO Surgery?

Normal bruising after TPLO surgery usually appears as a purple, blue, or reddish discoloration around the incision or leg. It often develops within 24 to 48 hours post-surgery and gradually fades over 1 to 2 weeks.

Knowing the typical appearance and timeline of bruising helps you track your dog’s healing and identify abnormal changes early.

• Color changes: Bruises typically start dark purple or blue, then change to green, yellow, and finally fade as healing progresses over days to weeks.
• Size and spread: Normal bruising is usually localized near the incision and does not spread extensively to other parts of the leg or body.
• Swelling presence: Mild swelling often accompanies bruising but should not cause severe discomfort or limb deformity.
• Pain level: Some tenderness is expected, but your dog should not show signs of severe pain or limping beyond normal post-surgical recovery.

Monitoring these signs helps ensure bruising is part of normal healing and not a sign of infection or bleeding complications.

How Should You Care for Bruising After TPLO Surgery?

Proper care reduces bruising severity and supports healing after TPLO surgery. Following your veterinarian’s instructions and providing gentle care helps your dog recover comfortably and safely.

Simple steps at home can minimize bruising and swelling while preventing complications.

• Rest and restricted activity: Limit your dog’s movement to prevent pressure on the surgical site and avoid worsening bruising or swelling.
• Cold compress application: Applying a cold pack wrapped in cloth for 10–15 minutes several times daily during the first 48 hours can reduce swelling and bruising.
• Proper bandage care: Keep any surgical bandages clean and dry, and follow your vet’s instructions on changing or removing them to avoid irritation.
• Medication adherence: Administer all prescribed painkillers and anti-inflammatory drugs exactly as directed to control pain and reduce inflammation.

Consistent care helps your dog heal faster and reduces the risk of bruising-related complications.

When Should You Be Concerned About Bruising After TPLO Surgery?

While bruising is normal, certain signs indicate that your dog may need urgent veterinary evaluation. Recognizing these warning signs early can prevent serious complications.

If you notice any of the following, contact your veterinarian promptly for advice or examination.

• Rapidly expanding bruises: Bruising that spreads quickly or becomes very large may signal active bleeding or hematoma formation requiring medical attention.
• Excessive swelling and heat: Swelling that worsens with warmth and redness around the incision could indicate infection or inflammation needing treatment.
• Severe pain or lameness: If your dog shows intense pain, refuses to bear weight, or has a limp worsening over time, this may suggest complications.
• Discharge or foul odor: Any pus, bleeding, or bad smell from the surgical site is a sign of infection and requires immediate veterinary care.

Early detection of problems helps ensure timely treatment and better recovery outcomes.

Can Bruising Affect Your Dog’s Recovery After TPLO Surgery?

Bruising itself usually does not affect the overall success of TPLO surgery if it is mild and managed properly. However, severe bruising or related complications can delay healing and cause discomfort.

Understanding the impact of bruising helps you provide better care and communicate effectively with your veterinarian during recovery.

• Minor bruising benefits: Mild bruising is a normal sign of healing and usually resolves without affecting joint stability or function.
• Severe bruising risks: Large bruises or hematomas can increase pain, limit mobility, and sometimes require drainage or additional treatment.
• Infection risk: Bruised tissue is more vulnerable to infection, so keeping the area clean and monitoring closely is essential.
• Physical therapy considerations: Bruising may limit early physical therapy, so adjusting rehabilitation plans based on your dog’s condition is important.

Working closely with your vet ensures bruising does not interfere with your dog’s full recovery and return to normal activity.

How Can You Prevent Bruising After TPLO Surgery in Dogs?

While some bruising is unavoidable due to surgery, certain steps can reduce its severity and support smooth healing. Prevention focuses on careful handling and following veterinary guidance.

Taking precautions before and after surgery helps protect your dog’s tissues and blood vessels from excessive damage.

• Pre-surgery health check: Ensuring your dog is healthy and not on blood-thinning medications before surgery reduces bruising risk.
• Gentle post-op handling: Avoid rough play, jumping, or excessive pressure on the leg during recovery to prevent new bruises.
• Follow medication instructions: Use prescribed drugs properly and avoid over-the-counter medications without vet approval to prevent clotting issues.
• Regular veterinary follow-up: Attend all scheduled check-ups so your vet can monitor healing and address bruising or other concerns early.

Prevention and careful management promote a safer, faster recovery with minimal bruising complications.

Conclusion

Bruising after TPLO surgery in dogs is a common and usually normal part of the healing process. It results from surgical trauma and inflammation, appearing as discoloration near the incision site. Mild bruising typically resolves within two weeks without affecting recovery.

Proper care, including rest, cold compresses, and medication adherence, helps reduce bruising and supports healing. However, owners should watch for signs of excessive bruising, swelling, pain, or infection and contact their veterinarian promptly if these occur. Understanding bruising after TPLO surgery allows you to care for your dog confidently and ensure a smooth recovery.

FAQs

Is bruising after TPLO surgery normal for all dogs?

Yes, mild bruising is common after TPLO surgery due to tissue trauma and inflammation. However, the amount varies by individual and surgical factors.

How long does bruising last after TPLO surgery?

Bruising usually appears within 1–2 days after surgery and fades over 1 to 2 weeks as the tissues heal naturally.

Can I use cold packs on my dog’s bruising after surgery?

Yes, applying cold compresses wrapped in cloth for 10–15 minutes several times daily during the first 48 hours helps reduce swelling and bruising.

When should I call the vet about bruising after TPLO?

Contact your vet if bruising spreads rapidly, swelling worsens, pain is severe, or if there is discharge or foul odor from the incision.

Does bruising affect my dog’s ability to walk after TPLO surgery?

Mild bruising usually does not affect walking, but severe bruising or pain may cause limping and require veterinary evaluation.

Keeping a dog calm during TPLO recovery is one of the hardest parts of the process -- and one of the most important.

A dog that feels physically capable of running at week 3 is not biologically ready to run at week 3. The osteotomy has not consolidated. The plate can fail.

Activity restriction is not optional.

Quick answer: Most effective strategies for keeping a dog calm after TPLO surgery: crate confinement during unsupervised periods, food puzzles and scent games, consistent pain management, a quiet low-stimulus environment, and trazodone or gabapentin for highly anxious dogs. Keep a leash on the dog indoors.

Key takeaways

• Crate confinement is the foundation of activity control: large enough to stand and turn but not pace; prevents the spontaneous running, jumping, and spinning that cause plate failure
• Mental stimulation substitutes for physical activity: food puzzles, lick mats, frozen Kongs, and scent games provide neural reward without physical impact
• Pain management compliance directly affects calmness: uncontrolled pain causes restlessness; giving NSAIDs and gabapentin on schedule keeps the dog comfortable enough to rest
• The environment must be actively managed: loud TV, visitors, and other pets cause arousal and movement; a quiet, predictable low-stimulus space reduces arousal
• Trazodone and gabapentin can be prescribed for highly anxious dogs: VetSurgInfo confirms trazodone is inexpensive, safe, and effective for anxiety and sedation during TPLO recovery
• Always use a leash indoors during early recovery: a dog that slips or startles can displace the plate; a house leash gives the owner control at all times

The crate: foundation of confinement

A crate is the safest confinement tool for TPLO recovery.

It limits the movements that risk plate failure -- spontaneous jumping, running to the door, sudden pivoting -- and gives the dog a defined, safe space.

Crate selection:

• Large enough for the dog to stand, turn, and lie down comfortably
• Not so large the dog can pace or run inside
• Soft bedding on non-slip material
• Location in the household main area, not isolated -- isolation increases anxiety

SustainableVet.org confirms: use a crate, pen, or small room with non-slip flooring. Crates prevent jumping, running, and twisting. Choose a crate large enough to stand and turn.

Exercise pen alternative: for dogs that do not tolerate crates, an exercise pen (X-pen) provides a larger confined space while still restricting free movement. Place the X-pen in the main living area so the dog is not isolated.

Small room alternative: a bathroom, laundry room, or small bedroom with a baby gate can work. Remove furniture the dog could jump on.

Mental stimulation: the most underused tool

A dog confined physically but not cognitively engaged becomes frustrated, which leads to escape attempts and activity that risks the repair.

Mental stimulation provides the same dopamine reward as physical activity with zero mechanical risk.

Effective mental stimulation options:

Food puzzles and slow feeders: scatter meals in a puzzle feeder or across a lick mat instead of in a bowl. A meal that takes 15 minutes to eat provides significant cognitive engagement.

Frozen Kongs: stuff with wet food, peanut butter (xylitol-free), or kibble soaked in broth; freeze for several hours. A frozen Kong can occupy a dog for 20 to 30 minutes.

Sniff games: hide small treats in a folded towel, a muffin tin covered with tennis balls, or a scatter across the crate bedding. Sniffing is cognitively tiring -- it is physiologically equivalent to sustained physical exercise in terms of neural engagement.

Chew toys: long-duration chews (bully sticks, raw bones appropriate for the dog's size, frozen chicken necks) keep the dog occupied without movement.

Animal Outpatient Surgery confirms: soft music, white noise, or pheromone diffusers create a serene atmosphere. Mental engagement through food puzzles and scent games reduces frustration from limited mobility.

Environmental management

The dog's immediate environment directly controls arousal level.

Reduce auditory stimuli: loud TV, doorbell sounds, and street noise cause the dog to alert and attempt to move. White noise machines or calm background music reduce stimulus peaks.

Manage household traffic: visitors who excite the dog, children who rough-house nearby, and other pets that want to interact all cause arousal. Limit access to the dog during early recovery.

Manage other pets: other dogs and cats approaching the recovering dog cause arousal and can trigger sudden jumping or running. Keep them separated during the early weeks, particularly unsupervised.

Non-slip flooring: rugs and yoga mats in the dog's movement area prevent slipping, which generates uncontrolled leg movements that can stress the plate.

Laveen Vet Center confirms: set up a quiet, confined area free from loud noises, active children, and other pets. White noise or soft music helps create a serene atmosphere.

Pain management and its role in calmness

An undertreated dog is a restless dog. Pain creates the exact behaviors -- panting, pacing, inability to settle, licking the leg -- that also indicate anxiety.

Distinguishing pain from anxiety is important because the response is different.

Pain management checklist:

• Give NSAIDs and gabapentin on the exact schedule prescribed, not as needed
• Never skip doses because the dog appears comfortable -- the medication is maintaining that comfort
• Give medications approximately 30 minutes before walks (TPLO home recovery protocols recommend this timing)
• Contact your vet if the dog cannot settle despite correct medication administration

VetSurgInfo confirms: gabapentin provides both analgesia and sedation; the sedating effect facilitates recovery and rest, particularly in the first 7 days.

Prescribed calming medications

For dogs with high anxiety, separation anxiety, or an inability to settle despite environmental and mental stimulation management, veterinary-prescribed medications are appropriate and safe.

Trazodone: a serotonin modulator used off-label in dogs for anxiety and sedation. VetSurgInfo confirms: dogs do very well on trazodone for anxiety and sedation during TPLO recovery; it is inexpensive and can facilitate recovery, rest, and calm during vet visits.

Gabapentin: the analgesic side effect of sleepiness helps with calmness in addition to pain control.

Alprazolam or other benzodiazepines: may be appropriate for situational anxiety (specific triggers like thunder).

SustainableVet.org confirms: vets can prescribe mild sedatives or calming medications for dogs who remain overly anxious; these drugs are safe when dosed correctly and can prevent harmful overactivity.

Never give human anxiety medications to dogs. Never use human supplements without vet approval -- some contain xylitol or other ingredients toxic to dogs.

Owner behavior and management

Owners unintentionally promote activity.

Do not excitedly greet the dog: excited greetings cause the dog to jump and spin. Calm, quiet greetings reduce arousal.

Leash the dog indoors: a house leash (a short, light leash attached to the collar) gives the owner control when the dog is out of the crate. If the dog startles or tries to move suddenly, the leash prevents uncontrolled movement.

Maintain a predictable routine: dogs are routine-oriented. Predictable meal times, bathroom walk times, and crate times reduce anticipatory anxiety. Variation creates excitement; routine creates calm.

Keep visits short: sitting with the dog is good. Prolonged exciting interaction is not. Brief, calm contact several times daily is better than one long exciting session.

Frequently asked questions

My dog screams and cries in the crate for hours. What do I do?

Contact your vet. Sustained, intense crate distress may indicate: inadequate pain control (the dog is in pain, not just anxious), genuine severe separation anxiety, or insufficient mental stimulation.

Ask about trazodone or gabapentin for anxiety management. Do not give up on crate confinement -- the alternative is uncontrolled movement that risks the repair.

Is it okay to let my dog out of the crate to sit with me on the sofa?

Only if the dog is on a leash and cannot jump. Allow the dog to lie next to you on the floor or on a low dog bed beside you.

Do not allow the dog onto the sofa -- falling or jumping off generates the same plate-failure risk as running.

My dog seems much better at 3 weeks. Can I relax the restrictions?

No. Clinical improvement does not mean bone healing is complete. The osteotomy is not confirmed healed until radiographs at 8 to 12 weeks.

Plate failure typically happens when owners relax restrictions based on the dog appearing well. Maintain full restrictions until vet clearance.

What is the best medication for a high-energy dog that can't settle?

Trazodone is the most commonly prescribed agent for activity restriction in TPLO dogs. It is effective, safe, inexpensive, and can be used for the full restriction period.

Discuss with your vet at or before surgery -- it is easier to start early than to address a crisis at week 2.

Can I take my dog to visit friends or family during recovery?

Very limited visits in controlled, quiet environments where the dog is leashed and confined.

No visits to households with other active dogs, children who will excite the dog, or any environment where the dog cannot be kept calm. Unfamiliar environments increase anxiety and exploration behavior.
