Urinary incontinence after TPLO surgery is not a common complication, but it does occur and is understandably alarming for owners.
In most cases it is a temporary consequence of anesthesia, pain medication, stress, or reduced mobility not a sign of a serious surgical problem.
Knowing the causes, the timeline, and when to call your vet helps you respond appropriately.
Quick answer: Incontinence after TPLO is usually temporary from anesthesia, pain medications, reduced mobility, or stress. Most cases resolve within days to weeks. Call your vet if it persists beyond 2 to 4 weeks or comes with bloody urine or fever.
Key takeaways
- Immediate post-TPLO incontinence is most often from anesthesia or nerve irritation: both are temporary and resolve within days to weeks
- Opioid pain medications cause urinary retention or reduced bladder awareness in some dogs this resolves as medications are tapered
- Postoperative swelling may temporarily irritate nerves involved in bladder control; this resolves with swelling
- Reduced mobility is a practical contributor: a confined, painful dog may not signal in time or reach the door quickly
- Stress after major surgery can cause accidents in previously house-trained dogs; this is behavioral, not neurological
- Genuine nerve damage from TPLO is rare: incontinence persisting beyond 6 weeks warrants neurological evaluation
Why dogs may become incontinent after TPLO surgery
Anesthesia effects
General anesthesia temporarily suppresses normal nerve function throughout the body, including the neural pathways that control bladder filling awareness and sphincter tone.
As anesthetic drugs are metabolized over the 12 to 24 hours after surgery, some dogs have reduced bladder control.
This is the most common cause of immediate post-surgical incontinence. It resolves as anesthesia fully clears, typically within 24 to 48 hours.
Nausea, disorientation, and general sedation from anesthesia also mean the dog may not signal clearly when they need to go outside.
Scheduled outdoor bathroom trips every 2 to 4 hours in the first 24 to 48 hours post-surgery help manage this.
Opioid and sedative medications
Opioid pain medications commonly prescribed after TPLO affect bladder control in two ways: they reduce awareness of bladder fullness, and in some dogs cause urinary retention.
Both effects resolve as medications are tapered in the days following surgery.
Retention and incontinence are opposite problems retention is not urinating at all, while incontinence is involuntary urination but both can occur at different times as different medications have their effects.
As pain medications are tapered in the days after surgery, these effects resolve for most dogs.
Postoperative swelling and nerve irritation
The proximal tibia is surrounded by neurovascular structures. Postoperative swelling around the surgical site may temporarily compress or irritate nerves that travel to the bladder and urethra.
This is more likely in the first week after surgery when swelling is at its peak.
This type of incontinence improves as swelling resolves and typically does not indicate permanent nerve damage.
Reduced mobility
A dog recovering from TPLO is confined, in pain, and may not reach the door quickly enough when the bladder signals urgency.
This is a practical mobility problem, not a neurological one.
Frequent scheduled outdoor trips every 2 to 4 hours in the first week reduce accidents significantly. Waterproof mattress covers and washable bedding help manage the recovery period hygienically.
Stress and behavioral response
Major surgery is a significant stressor. Pain, an unfamiliar environment, an E-collar, restricted movement, and disrupted routine can cause previously house-trained dogs to have accidents unrelated to neurological dysfunction.
This type of incontinence typically resolves as the dog settles into a recovery routine at home, usually within 1 to 2 weeks.
Pre-existing urinary conditions
Dogs with pre-existing urinary sphincter mechanism incompetence (common in middle-aged spayed females), bladder infections, or weak bladder control may show worsened incontinence after surgery.
Anesthesia, medications, and reduced mobility all unmask or worsen underlying conditions.
If your dog was occasionally leaking urine before surgery, report this to your vet during the pre-surgical assessment so appropriate management can be planned for the recovery period.
Types of post-TPLO incontinence by timing
Immediate (within 24 to 48 hours): almost always anesthesia effects or opioid medication. Expected and self-limiting.
Early post-operative (days 3 to 14): medication effects, swelling-related nerve irritation, mobility limitation, or stress. Usually self-limiting with appropriate management.
Delayed onset (weeks 2 to 6): may indicate a developing urinary tract infection (UTI), which can occur after catheterization during surgery or from reduced immune response. A urinalysis is warranted if incontinence appears or worsens after initial improvement.
Chronic (beyond 6 weeks): uncommon. If incontinence persists beyond 6 weeks without improvement, veterinary evaluation for nerve damage or underlying urinary tract disease is appropriate.
Home management during recovery
- Scheduled outdoor bathroom trips every 2 to 4 hours for the first 1 to 2 weeks
- Waterproof mattress protectors and washable bedding in the recovery area
- Non-slip surfaces to reduce the effort required to stand and move toward the door
- Monitor urine color and odor cloudy, bloody, or foul-smelling urine suggests UTI
- Keep the genital area clean to prevent skin irritation from urine contact
- Use a belly band (for males) or absorbent dog diapers if incontinence is significant
When to contact your veterinarian
Call your vet if:
- The dog cannot urinate at all for more than 12 to 24 hours after surgery
- Urine is bloody, cloudy, or has a strong unusual odor (UTI signs)
- Incontinence is accompanied by straining, crying during urination, or frequent squatting without producing urine
- Incontinence worsens after initial improvement
- The dog has persistent incontinence beyond 2 to 4 weeks without any improvement
- Incontinence is combined with significant worsening lameness or systemic signs

Frequently asked questions
Is incontinence normal after TPLO surgery?
Temporary incontinence particularly in the first 24 to 48 hours is a recognized post-surgical finding related to anesthesia and opioid pain medications.
It is not an expected routine outcome, but it is not rare. If it resolves within a few days, it was almost certainly anesthesia-related.
Could my dog have nerve damage from TPLO surgery?
True nerve damage causing persistent incontinence from TPLO is rare. TPLO is performed at the proximal tibia, which is some distance from the pelvic nerves controlling bladder function.
Temporary nerve irritation from swelling is much more common than actual nerve injury and resolves as swelling subsides.
My dog was continent before TPLO and is now leaking at night. Why?
Nighttime leaking specifically is typical of urinary sphincter mechanism incompetence (USMI) a condition where the urethral sphincter relaxes during sleep or rest.
If this is new after surgery, anesthesia and opioid medications may have temporarily worsened underlying borderline sphincter function.
If it continues beyond 2 to 3 weeks, a vet visit for urinalysis and discussion of phenylpropanolamine (PPA) or other treatment is appropriate.
How do I know if my dog has a UTI after TPLO?
Signs of UTI include: cloudy or bloody urine, strong or unusual odor, frequent small amounts of urination, straining to urinate, and licking at the genital area more than normal.
Some dogs with UTI also show lethargy and decreased appetite. Urinalysis and culture confirm the diagnosis.
Should I limit my dog's water intake to reduce accidents?
No. Do not restrict water. Hydration is important for recovery and kidney function. Restricting water can concentrate the urine and increase UTI risk.
Instead, manage accidents through scheduled outdoor trips and waterproof bedding.

Things to know

Bruising After TPLO Surgery in Dogs
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.

What is TPLO Surgery in Dogs?
TPLO (tibial plateau leveling osteotomy) is the most widely performed surgery for cranial cruciate ligament (CCL) rupture in dogs.
It is the procedure most commonly recommended by board-certified veterinary surgeons for medium and large dogs, and it has the most extensive published evidence base of any CCL repair technique.
Understanding what TPLO is, why it works, and what recovery involves helps owners make informed decisions and prepare for the process.
Quick answer: TPLO (tibial plateau leveling osteotomy) corrects CCL rupture by changing tibial plateau geometry to eliminate the shear force making the CCL unnecessary. A curved cut is made through the tibia, rotated to 5 degrees, and secured with a locking plate while the bone heals. Success rate is 90 to 95%.
Key takeaways
- TPLO stands for tibial plateau leveling osteotomy: it levels the tibial plateau through a bone cut to stabilize the stifle without relying on the damaged CCL
- TPLO corrects CCL rupture by eliminating the shear force the CCL resists: it changes the tibial plateau geometry so the joint is stable without a CCL
- The procedure achieves a post-operative tibial plateau angle of approximately 5 degrees: VCA confirms the tibial plateau is rotated until appropriately level (ideally 5 degrees), eliminating cranial tibial thrust
- TPLO has a 90 to 95% success rate: RCVS confirms 90 to 95% of dogs regain complete or near-complete function; 93% of owners report satisfaction at 12 months
- Recovery requires 8 to 12 weeks of activity restriction for bone healing; progressive return to full activity follows; muscle recovery takes up to 6 months
- TPLO is the most commonly recommended procedure for CCL rupture by ACVS surgeons in dogs over approximately 15 to 20 kg
The CCL and why it ruptures
The cranial cruciate ligament (CCL) is the equivalent of the human ACL in dogs.
It connects the femur (thigh bone) to the tibia (shin bone) inside the stifle (knee) joint and serves three primary functions:
- Preventing the tibia from sliding forward relative to the femur during weight bearing
- Limiting internal rotation of the tibia
- Preventing hyperextension of the stifle
Unlike most human ACL tears (which are acute traumatic events), CCL rupture in dogs is typically degenerative. The fibers weaken progressively over months to years before the ligament fails completely.
By the time complete rupture occurs, most of the fibers have already been compromised.
This is why the contralateral (opposite) CCL is also at risk -- the same degenerative process typically affects both stifles.
When the CCL ruptures, the tibial plateau's natural slope creates an unconstrained cranial shear force during weight bearing.
The femur slides down the tibial plateau, the tibia shifts forward, and the dog is in pain and unable to use the leg normally.
CCL rupture is one of the most common orthopedic injuries in dogs. High-risk breeds include Labrador Retrievers, Rottweilers, Staffordshire Terriers, Mastiffs, Newfoundlands, and German Shepherds.
Neutered dogs have a higher risk than intact dogs of the same breed.
How TPLO works: the biomechanical principle
The normal canine tibial plateau slopes downward from front to back at approximately 23 to 29 degrees (the tibial plateau angle, or TPA).
When the dog bears weight, this slope creates a cranial shear force -- the tibia tries to slide forward relative to the femur. In a normal stifle, the CCL resists this force.
When the CCL is absent, the force is unopposed and the joint is unstable.
TPLO does not attempt to restore the CCL. Instead, it eliminates the shear force entirely.
By rotating the tibial plateau to approximately 5 degrees, the joint surface becomes level enough that the patellar tendon -- rather than the CCL -- provides the stabilizing force during weight bearing.
The joint is mechanically stable without any ligament. The need for the CCL is eliminated by changing the geometry of the tibial plateau.
Dispomed confirms: TPLO addresses CCL rupture by altering the biomechanics of the stifle. The tibial plateau normally slopes downward; TPLO creates a flat or level plateau, decreasing sliding motion at this joint.
The TPLO procedure: step by step
Pre-operative planning
Before surgery, the dog is sedated and lateral stifle radiographs are taken.
The surgeon measures the TPA from these images and calculates the amount of rotation required to achieve the target post-operative TPA of approximately 5 degrees.
The surgeon also selects the appropriate saw blade radius and implant size based on these measurements and the dog's body weight.
Anesthesia and preparation
The dog is placed under general anesthesia. The surgical site is clipped and prepared with antiseptic solution. IV antibiotics (typically cefazolin) are given before the incision.
Joint inspection and meniscal assessment
The surgeon makes an incision over the medial aspect of the proximal tibia and performs a small arthrotomy (opening into the joint) to inspect the menisci.
Damaged meniscal tissue is removed at this stage.
Chewy confirms: during surgery, the joint is examined and the surgeon might remove damaged tissue before proceeding with the osteotomy.
The osteotomy
Using a specialized oscillating saw blade, the surgeon makes a curved (arcuate) cut through the proximal tibia at the level of the tibial plateau.
The radius of this cut is determined by the pre-operative planning.
Rotation
The cut bone segment (containing the tibial plateau) is rotated backward (caudally) by the calculated amount to achieve the target TPA.
VCA Animal Hospitals confirms: the top section of the tibia is rotated backward until deemed appropriately level -- typically 2 to 14 degrees, with 5 degrees as the ideal angle.
Plate fixation
A TPLO plate (a contoured locking plate) is secured to the tibia across the osteotomy using locking screws. The plate holds the rotated tibial plateau in position while the bone heals.
Closure
The joint capsule, fascia, subcutaneous tissue, and skin are closed in layers. The incision is bandaged.
Success rate and outcomes
RCVS Canine Cruciate Registry confirms: TPLO has a 90 to 95% success rate, with 90 to 95% of dogs regaining complete or near-complete function; 93% of owners reporting satisfaction at 12 months.
A 2013 study found that TPLO patients achieved 93% restoration of limb function at 1 year.
TPLO produces better long-term outcomes than lateral suture stabilization in most studies of large dogs, and similar long-term outcomes to TTA in comparable patient populations.
RCVS confirms: all dogs with CCL rupture are expected to develop at least some osteoarthritis, but this is reduced or delayed in dogs that have had surgical stabilization.
Recovery overview
- Weeks 0 to 2: crate rest, 5-minute bathroom leash walks only, e-collar on at all times
- Weeks 2 to 6: graduated leash walk increase, passive range-of-motion exercises
- Week 6: radiographic assessment of bone healing; activity increase if healing is progressing
- Weeks 8 to 12: final radiographic confirmation of bone healing; activity restrictions lifted if healing is confirmed
- Months 3 to 6: progressive return to full activity; muscle recovery continues

Frequently asked questions
Is TPLO the only surgery for CCL rupture in dogs?
No. The main alternatives are lateral suture stabilization (extracapsular repair), TTA (tibial tuberosity advancement), and CBLO (CORA-based leveling osteotomy). Lateral suture achieves good outcomes in dogs under approximately 35 pounds.
TTA produces similar long-term outcomes to TPLO in appropriately selected dogs. CBLO is used mainly for immature dogs and revision surgery cases.
Can a dog live without surgery for CCL rupture?
Small dogs (under 10 to 15 kg) sometimes stabilize adequately with conservative management (strict rest, weight management, joint support).
For most dogs over 15 kg, conservative management does not restore normal joint stability and the dog remains in pain with progressive arthritis.
Surgery is strongly recommended for most medium and large dogs.
How long does TPLO surgery take?
The procedure typically takes 1.5 to 2 hours. Bilateral simultaneous TPLO takes 3 to 4 hours.
Does the TPLO plate stay in permanently?
Yes, in most cases. The plate is not routinely removed after the osteotomy heals. It is removed if it causes complications (infection, implant irritation, failure).
What is the cost of TPLO surgery?
TPLO typically costs $3,500 to $6,000 per stifle depending on the facility, surgeon, geographic location, and the dog's size.
This typically includes the surgical procedure, anesthesia, hospitalization, implants, and the immediate post-operative period.

Alternatives to TPLO Surgery for Dogs
TPLO is the most commonly recommended surgical procedure for CCL rupture in medium and large breed dogs, but it is not the only option and it is not always the right option.
Some dogs are better served by a different surgical technique; others by non-surgical management. Understanding the full menu of alternatives helps owners have more informed conversations with their veterinarians.
Quick answer: Surgical alternatives to TPLO include TTA, extracapsular repair, Tightrope, MMP, and CBLO — most achieving 90 to 93% good function in the right patient. Non-surgical options produce variable outcomes and are not recommended for complete CCL rupture in large dogs.
Key takeaways
- Surgical alternatives achieve comparable outcomes in the right patient: TTA and Tightrope show 90 to 93% good function at one year
- Extracapsular repair is appropriate for dogs under 15 to 35 lbs: above 90% success in small dogs; significantly worse in larger breeds
- Conservative management is not recommended for large dogs with complete CCL rupture: outcomes are worse; appropriate only for comorbidities or small partial tears
- Knee braces do not have strong evidence of restoring joint stability; current studies show no significant benefit per Vetamac
- MMP and CBLO are newer alternatives with growing evidence: MMP uses a titanium wedge; CBLO uses a different osteotomy geometry
- The best alternative to TPLO is determined by dog size, activity level, surgeon training, and individual clinical factors not by owner preference alone
Surgical alternatives
TTA (Tibial Tuberosity Advancement)
TTA advances the tibial tuberosity cranially to change the angle of the patellar tendon relative to the tibial plateau.
This achieves mechanical neutralization of cranial tibial thrust through a different geometric approach than TPLO.
TTA is appropriate for large breed dogs, similar to TPLO. Studies show comparable outcomes at one year.
DVM360 notes that TTA recovery may be faster in the early post-operative period than TPLO, though TPLO tends to show better objective outcomes in size-matched longer-term comparisons.
For the full TTA vs TPLO comparison, see TPLO, CBLO, and TTA: a guide to cruciate surgery options.
Extracapsular repair (DeAngelis/lateral suture/ELSS)
Extracapsular repair uses a heavy suture outside the joint to stabilize the stifle.
It is the oldest and most widely available CCL repair technique and is appropriate for small dogs under 15 to 35 lbs.
Simon Veterinary Surgical confirms extracapsular repair achieves excellent results in appropriately sized patients (typically under 50 lbs), with many dogs living full, active lives.
In larger, more active dogs, the suture eventually stretches or fails, and outcomes are consistently inferior to TPLO.
Today's Veterinary Practice confirms TPLO produces higher peak vertical force and higher owner satisfaction at one year compared to extracapsular repair in size-matched dogs.
For the full comparison, see DeAngelis vs TPLO surgery for dogs.
Tightrope procedure
Tightrope uses a synthetic fiber-tape passed through bone tunnels in the femur and tibia to stabilize the stifle.
It is more anatomically positioned than extracapsular repair and achieves comparable outcomes to TPLO at 6 months in published comparative studies.
Tightrope is appropriate for small to medium dogs and as a less expensive alternative to TPLO. Dr.
Buzby's rehabilitation veterinary guide lists Tightrope among the established surgical options alongside TPLO, TTA, ELSS, and CBLO.
For the full comparison, see Tightrope vs TPLO surgery for dogs.
Modified Maquet Procedure (MMP)
MMP is an evolution of TTA that uses a porous titanium foam wedge instead of a cage to advance the tibial tuberosity.
It is less invasive and faster than TPLO, with comparable 6-month outcomes in the primary randomized study.
MMP is appropriate for medium and large breed dogs in the hands of surgeons trained in the technique.
For the full comparison, see Modified Maquet Procedure vs TPLO surgery.
CBLO (CORA-Based Leveling Osteotomy)
CBLO is a newer osteotomy technique that applies a different geometric principle to achieve tibial plateau leveling.
Rather than a radial osteotomy (as in TPLO), CBLO uses the CORA (center of rotation of angulation) to guide a wedge osteotomy.
Published success rates of 85 to 95% good function have been reported.
CBLO is an emerging alternative with growing evidence. For the full comparison, see CORA-based leveling osteotomy vs TPLO in dogs.
Zlig
Zlig is a synthetic implant placed inside the joint to replace the function of the CCL.
It is a less commonly discussed alternative with limited long-term veterinary evidence compared to the established osteotomy techniques.
For the full comparison, see Zlig vs TPLO: which surgery is better for dogs?.
Non-surgical alternatives
Conservative management
Conservative management refers to non-surgical approaches: strict rest and activity restriction, physical therapy and rehabilitation, weight management, NSAIDs for pain and inflammation control, and joint supplements.
Vetamac confirms: the main non-surgical treatments for CCL rupture include restricting activity, promoting weight loss, and physical therapy.
NSAIDs help manage pain and inflammation, although lameness persists as long as joint instability remains.
Simon Veterinary Surgical's guide notes: non-surgical outcomes are described as achieving "pasture soundness" comfortable for daily activities but the dog may not return to high-impact sports.
Consistency with physical therapy and weight management is the biggest predictor of good conservative outcomes.
When conservative management is appropriate:
- Dogs with serious concurrent medical conditions that make anesthesia high-risk
- Small dogs (under 10 to 15 lbs) with partial CCL tears
- As a temporary bridge to surgery when surgery is delayed
- Dogs whose owners cannot afford surgical options
When conservative management is not appropriate:
- Complete CCL rupture in dogs over 15 to 20 lbs lameness persists, arthritis progresses faster, and meniscal injury risk remains
- Active working dogs or dogs with high functional demands
For the full non-surgical guide, see non-surgical alternatives to TPLO surgery for dogs.
Orthopedic knee braces
Custom orthopedic braces provide external support to the stifle. They are sometimes used in dogs that cannot undergo surgery or during the waiting period before surgery.
Vetamac notes directly: current studies do not show significant benefits from orthopedic braces for CCL rupture.
They may improve comfort for some dogs but do not restore joint stability or prevent ongoing meniscal damage and arthritis progression. They are not a reliable substitute for surgical stabilization.
Regenerative medicine
Platelet-rich plasma (PRP) and stem cell therapy are emerging adjuncts.
Evidence for repairing a ruptured CCL is limited. These approaches may reduce inflammation but cannot restore the structural integrity that surgery provides.
Choosing between alternatives
| Option | Best for | Outcomes |
|---|---|---|
| TPLO | Large active dogs (30+ lbs) | 93% good function at 1 year |
| TTA | Large dogs, surgeon preference | Comparable to TPLO at 1 year |
| MMP | Medium-large dogs, less invasive preference | Comparable to TPLO at 6 months |
| Extracapsular | Small dogs under 15 to 35 lbs | Excellent in small dogs; fails in large |
| Tightrope | Small-medium dogs, lower cost | Comparable to TPLO at 6 months |
| Conservative | Small dogs, comorbidities, cost barrier | Variable; pasture soundness only |
| Knee brace | No surgery possible | Comfort only; no stability restoration |

Frequently asked questions
What is the best alternative to TPLO for a large dog?
TTA and MMP produce comparable outcomes to TPLO in large breed dogs and are appropriate alternatives.
Tightrope is less commonly recommended for very large dogs due to concerns about long-term stability at high joint forces.
The best choice depends on the individual dog, the surgeon's training and preference, and the specific clinical findings.
Can small dogs avoid surgery altogether?
Sometimes. Small dogs under 10 to 15 lbs with partial CCL tears sometimes achieve acceptable function with conservative management. However, surgery produces better outcomes even in small dogs.
If conservative management is chosen, strict weight management and physical therapy are essential.
Is a knee brace a good alternative to surgery?
Not as a primary treatment for complete CCL rupture. Braces may provide comfort and are sometimes used as a temporary measure or for dogs that truly cannot undergo surgery.
Vetamac confirms that current evidence does not support braces as an effective alternative to surgical stabilization.
How do I know which surgery is right for my dog?
A board-certified orthopedic surgeon (ACVS diplomate) is the most qualified person to advise on surgical selection for your specific dog.
Factors include body weight, tibial plateau angle, activity level, surgeon experience, and cost. General practitioners often refer to specialists for this decision.
Can a dog have a different surgery if the first one fails?
Yes. TPLO is a common revision option when extracapsular repair fails.
Different surgical approaches can be used as revisions depending on the original procedure, the current clinical state, and the degree of healing that has occurred.

Before performing TPLO surgery, the veterinary surgeon selects the appropriate bone plate from a range of sizes specific to the implant system being used.
The plate size chart is the reference tool that guides this selection.
Choosing the correct plate is as important as the surgical technique itself an undersized plate risks mechanical failure, and an oversized plate may not fit the tibial anatomy correctly.
Quick answer: The TPLO plate size chart matches body weight and tibial bone dimensions to the appropriate implant. Arthrex plates range from 2.0 mm to 4.5 mm; Synthes covers a similar range. Tibial width is measured on preoperative radiographs and used alongside body weight to select the plate and screw configuration.
Key takeaways
- The plate size chart is a preoperative planning tool that matches body weight and bone dimensions to the appropriate implant
- Arthrex offers TPLO plates from 2.0 mm to 4.5 mm: the small sizes are purpose-designed for small breed anatomy, not scaled-down large plates
- Tibial width is measured on preoperative radiographs: a primary determinant of plate selection alongside body weight
- Plate selection is system-specific: Arthrex plates require Arthrex instruments and screws; Synthes requires Synthes-specific tools
- The plate is single-use sterile: a new plate must be available if a different size is needed intraoperatively
- Correct plate selection directly affects outcomes: undersized plates risk fatigue fracture; oversized plates cause soft tissue irritation
What the plate size chart does
The TPLO plate size chart is a lookup reference similar in function to the rotation chart and weight chart that are part of the Arthrex and Synthes TPLO planning systems.
It takes known inputs (primarily body weight and tibial dimensions measured on radiographs) and outputs the recommended plate size from the manufacturer's product range.
SustainableVet.org explains: a TPLO plate size chart is a reference guide used by veterinary surgeons to select the appropriate implant size for stabilizing the tibia after TPLO surgery.
Plates come in various lengths and hole numbers to fit different dog breeds and bone sizes.
The chart removes the guesswork from a decision that significantly affects the mechanical performance of the repair.
A plate that is correctly sized distributes load evenly across all screw holes and lies flush against the cortical bone surface, minimizing stress risers and soft tissue irritation.
Key variables in plate size selection
Body weight
Body weight is the primary initial filter. Heavier dogs generate higher joint forces and require larger, stiffer plates to withstand the loads applied during weight-bearing and normal activity.
General size categories used across Arthrex and Synthes product lines:
- Small breed (under 10 to 15 kg): 2.0 mm or 2.4 mm plates
- Medium breed (15 to 30 kg): 3.5 mm plates
- Large breed (30 to 50 kg): 3.5 mm or 4.5 mm plates
- Giant breed (over 50 kg): 4.5 mm plates; locking systems particularly important
These ranges are approximate and surgeon-dependent. The specific manufacturer chart values take precedence over general categories.
Tibial width and bone dimensions
The plate must span the osteotomy site with at least 2 screws proximal and 2 screws distal to the cut for adequate fixation.
The tibial width at the planned osteotomy level measured in millimeters on a mediolateral radiograph determines which plate length and screw configuration provides sufficient purchase without overhanging the bone margins.
Number of screw holes
Plates are available with different numbers of holes (typically 4, 5, or 6 holes for standard sizes).
More holes provide more screw fixation points, which is important in larger dogs or those expected to be highly active during recovery.
SustainableVet.org notes: plates come in various lengths and hole numbers to fit different dog breeds and bone sizes, allowing surgeons to select the configuration that best matches each individual patient's anatomy.
Arthrex TPLO plate system
Arthrex produces the most widely used TPLO locking plate system in the United States. The Arthrex TPLO Locking Plate System is designed with specific anatomical features to facilitate consistent plate placement.
From Arthrex Vet Systems documentation: the 2.0 mm and 2.4 mm TPLO locking plates are not simply shrunken versions of larger TPLO plates.
The smaller plates were purpose-designed for small breed bone anatomy.
Small dogs have proportionally different tibial geometry, and scaling down a large plate does not optimize screw angle or load distribution.
Arthrex's 4.5 mm plate incorporates a caudal tilt designed for improved screw purchase in the proximal tibial segment, with a proximal screw trajectory directed to avoid the osteotomy line.
This is an important design feature: screws that inadvertently cross the osteotomy reduce fixation quality and risk creating a stress concentration at the cut.
The Arthrex system includes an InternalBrace ligament augmentation option for dogs with severe stifle instability. This knotless lateral stabilization technique is not part of standard TPLO.
For the Arthrex plate overview, see Arthrex TPLO plate overview and use. For the Synthes plate overview, see Synthes TPLO plate overview and use.
How the plate size chart integrates with other planning tools
The plate size chart is used in concert with two other charts in the preoperative planning sequence:
Rotation chart: determines how many degrees the tibial segment must be rotated to achieve the target postoperative TPA of approximately 5 degrees. This is completed using the preoperative TPA measurement from radiographs.
Weight chart: guides post-operative weight-bearing expectations during rehabilitation.
All three charts together form the complete preoperative planning and post-operative monitoring framework. For the rotation chart, see Arthrex TPLO rotation chart explained.
For the weight chart, see Arthrex TPLO weight chart explained.
Why correct plate size matters
Mechanical adequacy: the plate must be strong enough to withstand the bending forces applied across the osteotomy during recovery typically equivalent to body weight or more during brief dynamic loading events (jumping down from a bed despite restrictions). An undersized plate risks fatigue fracture if the osteotomy takes longer to heal than expected.
Biological fit: the plate must lie flush against the bone surface. A plate that sits proud causes soft tissue irritation and can lead to the implant-associated pain and lameness that eventually requires plate removal.
Screw purchase quality: screws that are too short for the bone depth, or too long and penetrating the far cortex inappropriately, compromise fixation quality. Plate size selection is linked to the specific screw lengths that are compatible with each plate variant.
Frequently asked questions
Can the surgeon change the plate size during surgery?
Yes. If the preoperatively planned plate size does not fit correctly once the osteotomy is made and the bone is positioned, the surgeon may open a different plate size.
This is why surgical teams keep a range of plate sizes available in the sterile field or immediately accessible.
The plate is a single-use sterile item it cannot be resterilized if opened and unused.
Are Arthrex and Synthes plates interchangeable?
No. Each manufacturer's plates require that manufacturer's specific screws, instruments, and jigs.
Using Synthes screws in an Arthrex plate (or vice versa) risks stripped screw heads, incorrect screw purchase geometry, and compromised fixation. The systems are entirely separate.
How does the surgeon know which plate to order before surgery?
The surgeon measures the tibial width and records body weight at the preoperative planning appointment.
Based on these measurements and the manufacturer's size chart, a specific plate and screw set is ordered or identified from the implant inventory before surgery.
Is a larger plate always better for a big dog?
Not necessarily.
The plate must fit the tibial anatomy. A plate longer than the available cortical surface overhangs the bone, creating soft tissue irritation and stress concentration at the plate ends.
The goal is the smallest plate that provides adequate mechanical fixation for the dog's body weight and expected activity level.
What happens if the wrong plate size is used?
An undersized plate risks fatigue fracture under repetitive loading. An oversized plate may not conform to the bone surface, reducing screw fixation quality and potentially causing soft tissue irritation.
Plate failure or malposition requiring revision is a recognized complication of poor implant selection.

Dog Whining After TPLO Surgery: Causes and Care
After your dog undergoes TPLO surgery, you might notice whining behavior that can worry you. Dog whining after TPLO surgery is common and can signal pain, discomfort, or anxiety during recovery. Understanding why your dog whines helps you provide better care and support during this critical healing phase.
This article explains the main reasons dogs whine after TPLO surgery, how to recognize when it is normal or concerning, and what steps you can take to ease your dog's discomfort. You will learn practical tips for managing pain, preventing complications, and promoting a smooth recovery.
Why is my dog whining after TPLO surgery?
Whining after TPLO surgery usually relates to pain or discomfort from the operation. Dogs cannot tell us how they feel, so whining is one way they express distress. It can also be a sign of anxiety or frustration due to restricted movement during recovery.
Recognizing the cause of whining helps you respond appropriately to your dog's needs and avoid unnecessary stress or complications.
- Postoperative pain: Pain from the surgical site is the most common reason for whining and usually peaks in the first few days after surgery.
- Restricted mobility: Limited ability to move or walk can cause frustration and whining as your dog adjusts to the recovery process.
- Anxiety or stress: Changes in routine, confinement, and discomfort can make your dog anxious, leading to vocalization like whining.
- Need for attention: Your dog may whine to seek comfort, reassurance, or physical contact from you during recovery.
Understanding these causes allows you to provide better comfort and care to your dog after TPLO surgery.
How can I tell if my dog’s whining is normal or a sign of a problem?
Not all whining after TPLO surgery is cause for alarm. Normal whining is usually mild and occurs during movement or when your dog is settling down. However, excessive or persistent whining may indicate complications or uncontrolled pain.
Knowing the difference helps you decide when to contact your veterinarian for advice or intervention.
- Normal whining: Occurs intermittently, especially when your dog tries to move or change position, and decreases over time.
- Signs of severe pain: Loud, continuous whining combined with limping, restlessness, or refusal to bear weight may signal uncontrolled pain.
- Signs of infection: Whining with swelling, redness, discharge, or foul odor at the surgical site requires immediate veterinary attention.
- Behavioral changes: Excessive whining with aggression, lethargy, or loss of appetite may indicate complications or distress.
Monitoring your dog closely and noting changes in whining patterns helps ensure timely care and prevents worsening conditions.
What pain management options are available after TPLO surgery?
Effective pain control is essential to reduce whining and promote healing after TPLO surgery. Your veterinarian will prescribe medications and suggest supportive measures to keep your dog comfortable.
Following the prescribed pain management plan closely improves your dog's recovery experience and reduces stress for both of you.
- Prescription painkillers: Non-steroidal anti-inflammatory drugs (NSAIDs) or opioids are commonly used to control postoperative pain safely.
- Cold therapy: Applying cold packs to the surgical area can reduce swelling and numb pain during the first 48 hours after surgery.
- Physical support: Using slings or harnesses helps your dog move without putting full weight on the operated leg, reducing pain during walking.
- Environmental comfort: Providing a quiet, soft resting area minimizes discomfort and encourages rest, which reduces whining.
Always follow your veterinarian's instructions on medication dosage and duration to avoid side effects or complications.
How should I care for my dog’s surgical site to reduce discomfort?
Proper wound care after TPLO surgery helps prevent infection and reduces pain that can cause whining. Keeping the surgical site clean and protected is vital during recovery.
Regular inspection and gentle care promote healing and comfort for your dog.
- Keep the incision dry: Avoid bathing or allowing water on the surgical site until your vet confirms it is safe to do so.
- Prevent licking or chewing: Use an Elizabethan collar or protective clothing to stop your dog from irritating the wound.
- Check for signs of infection: Look for redness, swelling, discharge, or foul smell and report concerns to your vet promptly.
- Follow dressing instructions: Change bandages as directed by your veterinarian to maintain cleanliness and support healing.
Consistent care of the surgical site reduces pain and helps your dog feel more comfortable during recovery.
What activity restrictions should I follow to help my dog heal?
Limiting your dog's activity after TPLO surgery is crucial to prevent injury and reduce pain that causes whining. Controlled movement supports proper healing and avoids complications.
Understanding and enforcing these restrictions ensures your dog recovers safely and comfortably.
- Strict confinement: Keep your dog in a small area or crate to limit running, jumping, or climbing for at least 6 to 8 weeks post-surgery.
- Leash walks only: Allow short, slow leash walks for bathroom breaks, avoiding off-leash activity or rough surfaces.
- Avoid stairs: Prevent stair climbing to reduce strain on the healing leg and minimize pain.
- Gradual reintroduction: Follow your veterinarian’s guidance to slowly increase activity as healing progresses, monitoring for any signs of discomfort.
Adhering to activity restrictions helps reduce whining caused by pain or injury during recovery.
When should I contact my veterinarian about my dog’s whining?
Knowing when to seek veterinary help is important if your dog’s whining signals a problem after TPLO surgery. Prompt attention can prevent complications and improve outcomes.
Being proactive about your dog’s symptoms ensures timely care and peace of mind.
- Persistent severe whining: If your dog whines continuously and shows signs of severe pain or distress, contact your vet immediately.
- Signs of infection: Whining accompanied by swelling, redness, discharge, or fever requires urgent veterinary evaluation.
- Changes in mobility: Sudden inability to bear weight or worsening lameness with whining should be assessed by a professional.
- Behavioral or appetite changes: Excessive whining with lethargy, aggression, or loss of appetite may indicate complications needing veterinary care.
Timely communication with your veterinarian helps ensure your dog’s recovery stays on track and reduces unnecessary suffering.
Conclusion
Dog whining after TPLO surgery is a common way your pet expresses pain, discomfort, or anxiety during recovery. Understanding the reasons behind the whining helps you provide better care and comfort to your dog.
By managing pain effectively, caring for the surgical site, restricting activity, and monitoring for complications, you can support your dog's healing and reduce distress. Always consult your veterinarian if you are concerned about your dog's whining or recovery progress.
FAQs
How long does whining usually last after TPLO surgery?
Whining typically decreases within the first two weeks as pain and discomfort lessen. Persistent or worsening whining beyond this period should be evaluated by a veterinarian.
Can I give my dog over-the-counter pain medication for TPLO recovery?
Do not give over-the-counter pain medications without veterinary approval, as some can be toxic to dogs or interfere with prescribed treatments.
Is it normal for my dog to whine at night after TPLO surgery?
Yes, dogs may whine at night due to discomfort or anxiety. Providing a comfortable, quiet space and following pain management helps reduce nighttime whining.
How can I comfort my dog when it whines after surgery?
Offer gentle petting, speak softly, and stay close to reassure your dog. Avoid excessive stimulation that may increase anxiety or pain.
When can my dog start physical therapy after TPLO surgery?
Physical therapy usually begins 1 to 2 weeks post-surgery, depending on healing progress. Follow your veterinarian’s recommendations for timing and exercises.

15 Common Complications After TPLO Surgery in Dogs
TPLO has a high overall success rate, but complications do occur. The published overall complication rate ranges from 10 to 34%, with most complications being minor and manageable.
Knowing what to watch for -- and when a sign requires a same-day call vs. a mention at the next scheduled appointment -- allows owners to respond appropriately.
Quick answer: The 15 most common post-TPLO complications: surgical site infection, seroma, implant loosening or failure, osteomyelitis, late meniscal tear, tibial tuberosity fracture, delayed bone healing, persistent lameness, non-union, intra-articular screw placement, nerve damage, patellar tendon thickening, patellar luxation, progressive osteoarthritis, and contralateral CCL rupture. Most are minor and manageable.
Key takeaways
- The overall complication rate is 10 to 34%: most complications are minor (swelling, mild infection); serious complications such as implant failure or osteomyelitis are less common
- SSI is the most frequent single complication: reported in 2.9% to 17.3% of TPLO procedures; most are superficial and treatable with antibiotics if caught early
- Late meniscal tear occurs in 1.8% to 10.5% of cases where the meniscus was normal at surgery; it presents as sudden lameness return with meniscal click
- Tibial tuberosity fracture is reported in 1 to 9% of TPLO cases: incorrect positioning and oversized saw blades are the main risk factors
- Implant-associated infection occurred in 3.4% and osteomyelitis in 0.6% across numerous studies; osteomyelitis requires strong antibiotics for 4 to 6 months and sometimes plate removal
- Contralateral CCL rupture is a significant long-term risk: 30 to 40% of dogs develop rupture of the opposite CCL; owners should monitor the opposite stifle
Early complications (weeks 0 to 8)
1. Surgical site infection (SSI)
The most common complication. SSI ranges from superficial incisional infection (treatable with oral antibiotics and wound care) to deep implant-associated infection requiring plate removal.
Signs: redness spreading beyond the incision, warmth, swelling, cloudy or malodorous discharge.
Incidence: 2.9% to 17.3% per published literature; the PMC 769-TPLO study (769 procedures) found 8.5%.
Management: culture-directed antibiotics for superficial infections; surgical debridement and sometimes plate removal for deep implant infections.
2. Seroma
A localized collection of clear serous fluid under the skin near the incision, typically appearing 1 to 3 weeks post-surgery.
Signs: soft, fluctuant swelling at or near the incision; no warmth or redness; clear fluid if aspirated.
Incidence: common; most resolve without treatment.
Management: monitoring; aspiration if large or causing discomfort; bandaging in some cases.
3. Acute lameness from overactivity
The dog is over-active during the restriction period and bears too much load on the plate before the osteotomy heals.
Signs: sudden worsening of lameness after a period of improvement; may indicate implant stress or early failure.
Management: strict crate rest; radiographic assessment to rule out implant displacement.
4. Wound dehiscence
The incision edges separate before fully healing. More common in dogs that lick the incision despite an e-collar that fits incorrectly.
Signs: open wound edges, sometimes with tissue visible.
Management: cleaning and re-closure in most cases; e-collar compliance review.
Mid-term complications (weeks 4 to 16)
5. Delayed bone healing
The osteotomy is not showing expected consolidation on radiographs at the 6 to 8 week checkpoint.
Signs: radiographic evidence of widening osteotomy gap or absence of callus formation; may or may not produce clinical signs.
Risk factors: infection, excessive activity, poor bone quality (older dogs, large breeds), NSAIDs at high doses for extended periods.
Management: extended activity restriction; investigate for underlying infection; nutritional support.
6. Tibial tuberosity fracture
A fracture of the tibial tuberosity (the prominence where the patellar tendon attaches) caused by the osteotomy saw blade coming too close to this structure.
Incidence: 1 to 9% per Laguna Woods Vets; higher in dogs with high TPA, high body weight, and large TPA change.
Signs: acute severe lameness; radiographic evidence of fracture.
Management: surgical repair or conservative management depending on displacement.
7. Late meniscal tear
A meniscal tear occurring after TPLO in a meniscus that appeared normal at surgery. See the dedicated meniscal tear article for full detail.
Incidence: 1.8% to 10.5% of cases with normal meniscus at TPLO (Dog Discoveries).
Signs: sudden lameness regression; meniscal click on movement; pain on stifle manipulation.
Management: partial meniscectomy.
8. Implant loosening or failure
The plate or screws shift, bend, or break -- typically from premature overactivity before the osteotomy heals.
Signs: sudden severe lameness; pain at plate site; radiographic evidence of screw loosening, plate migration, or osteotomy displacement.
Management: revision surgery in most cases of significant displacement.
Long-term complications (months 3 and beyond)
9. Osteomyelitis
Bone infection extending from a superficial SSI or introduced via hematogenous seeding. Difficult to treat.
Incidence: 0.6% per Dog Discoveries citing multiple studies.
Signs: persistent lameness; draining tract; radiographic bone destruction, periosteal reaction, or sequestrum.
Management: Laguna Woods Vets confirms osteomyelitis requires strong antibiotics for 4 to 6 months; a wound culture aids antibiotic selection; plate removal is often required.
10. Non-union
The osteotomy fails to heal, resulting in permanent instability at the cut site.
Risk factors: infection, inadequate fixation, excessive motion, poor blood supply.
Signs: persistent lameness; radiographic evidence of osteotomy gap persisting beyond 16 weeks with no bridging callus.
Management: revision surgery, bone grafting, and often implant revision.
11. Intra-articular screw placement
A screw tip violates the joint space, causing joint damage and persistent pain. Best identified on the postoperative radiograph.
Signs: ongoing lameness; pain on stifle range of motion; radiographic evidence of screw in joint space.
Management: removal of the offending screw.
12. Persistent lameness without identifiable cause
Some dogs have persistent mild lameness despite uncomplicated bone healing and no identifiable complication. This may reflect residual arthritis progression, muscle atrophy, or subclinical meniscal issues.
Management: rehabilitation, joint supplements, and management of secondary osteoarthritis.
13. Patellar tendon thickening
Fibrous thickening of the patellar tendon develops in some TPLO dogs over time. This is typically not clinically significant.
Signs: palpable thickening of the patellar tendon on examination; usually incidental finding.
Management: generally none required; physiotherapy in some cases.
14. Patellar luxation
Medial patellar luxation can develop or worsen after TPLO, particularly if the plate is contoured in a way that affects patellar tracking.
Signs: intermittent lameness, popping of the patella medially on examination.
Management: surgical correction (trochleoplasty and tibial crest transposition) in symptomatic cases.
15. Progressive osteoarthritis
All dogs with CCL disease develop some arthritis progression regardless of surgical technique. TPLO slows but does not stop this process.
Signs: gradual stiffness, lameness that is worse after rest, reduced activity tolerance.
Management: joint supplements (omega-3 fatty acids, glucosamine), weight management, NSAIDs for flares, hydrotherapy.
Contralateral CCL rupture: a special consideration
Contralateral CCL rupture is not a complication of TPLO but deserves mention.
Midvalley Animal Clinic confirms it is very common (30 to 40% of patients) for both knees to develop this ligament injury.
Owners of dogs that have had unilateral TPLO should monitor the opposite stifle for early signs.

For the failure rate overview, see TPLO failure rate in dogs. For the implant failure signs, see TPLO implant failure signs and causes.
Frequently asked questions
What is the most common serious complication after TPLO?
Deep implant-associated infection requiring plate removal is the most common serious complication, with an implant removal rate of 3.5 to 7.5% of procedures (ResearchGate).
Osteomyelitis (0.6%) and tibial tuberosity fracture (1 to 9%) are other serious but less common complications.
Is a 10 to 34% complication rate high for an orthopedic surgery?
The range is real but the majority of complications are minor -- a seroma, mild superficial infection treated with antibiotics, or a brief period of increased lameness.
Serious complications requiring revision surgery are significantly less common. TPLO's overall success rate (93% limb function restoration at 1 year per a 2013 study) reflects that most dogs recover well.
Can complications be prevented?
Most can be reduced in risk but not eliminated.
Owner-controlled risk reduction: e-collar compliance, strict activity restriction for 8 to 12 weeks, daily incision inspection, and attending all scheduled vet appointments.
What happens if my dog develops two complications simultaneously?
This is uncommon but does occur (for example, SSI leading to delayed bone healing). Management is coordinated by your surgical team based on the severity and interaction of the complications.
Contact your vet immediately for any concern.
Should I be worried every time my dog limps?
A degree of lameness is expected throughout the recovery period. The key signal is trajectory: steadily improving lameness is expected; suddenly worsening or reversed lameness is not.
Monitor for any sudden changes and contact your vet for trajectory reversals.

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.
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 Does TPLO Stand For in Veterinary Medicine?
If your dog has been diagnosed with a torn cranial cruciate ligament, you have likely encountered the acronym TPLO possibly before you knew what it meant or why it was being recommended.
TPLO is the most commonly performed CCL surgery in the US. Understanding what the acronym means helps demystify why the surgery works the way it does.
Quick answer: TPLO stands for Tibial Plateau Leveling Osteotomy: Tibial (shin bone), Plateau (upper surface forming the knee), Leveling (making the plateau closer to horizontal), Osteotomy (controlled bone cut). The surgery stabilizes the knee by rotating the tibia, making the CCL biomechanically unnecessary.
Key takeaways
- T = Tibial: the tibia, the shin bone below the knee (stifle) joint
- P = Plateau: the upper tibial surface forming the knee joint; in dogs it has a significant slope called the tibial plateau angle
- L = Leveling: reducing the tibial plateau angle to closer to parallel with the ground, changing joint biomechanics
- O = Osteotomy: a controlled surgical bone cut that allows the tibial segment to be repositioned and fixed
- TPLO does not repair the torn CCL: it changes joint geometry so the ligament becomes biomechanically unnecessary
- TPLO was first described in the early 1980s by Dr. Barclay Slocum and is now the most reliable procedure for CCL disease in dogs
Breaking down each word
T Tibial
The tibia is the main weight-bearing bone of the lower leg, running from the knee (stifle) joint to the ankle (tarsus).
In dogs, the tibia is not perfectly vertical it angles slightly forward relative to the femur above it. This angle contributes to the mechanical forces that act on the stifle during weight-bearing.
Veterinary Partner (VIN) explains: tibial refers to the shin bone.
P Plateau
The tibial plateau is the upper, relatively flat surface of the tibia that contacts the bottom of the femur to form the stifle joint.
Unlike in humans, where the tibial plateau is nearly horizontal, in dogs it has a significant slope the tibial plateau angle (TPA).
A steeper TPA creates more cranial tibial thrust during weight-bearing, which is the force that normally the CCL resists.
Veterinary Partner (VIN) defines it as: the upper surface of the shin bone; the bottom of the knee joint.
L Leveling
Leveling refers to the goal of the surgery: reducing the tibial plateau angle to approximately 5 degrees, making it closer to parallel with the ground.
When the tibial plateau is leveled, the femur no longer tends to slide forward relative to the tibia during weight-bearing the cranial tibial thrust is neutralized.
This is why a functioning CCL is no longer required after TPLO.
Veterinary Partner (VIN) defines it as: making the plateau more parallel to the ground.
O Osteotomy
An osteotomy is a controlled surgical cut through a bone a deliberate, planned fracture performed under anesthesia to allow repositioning of a bone segment.
TPLO involves a curved osteotomy through the proximal tibia, creating a segment that is rotated to the new angle and fixed with a bone plate and screws during healing.
Veterinary Partner (VIN) defines it as: a bone-cutting procedure like a controlled fracture of the bone.
Why TPLO was developed
Before TPLO, the dominant approach to CCL repair was extracapsular stabilization placing sutures outside the joint to mimic the CCL's function.
While effective in small dogs, this approach was unreliable in large, active dogs because the suture material eventually stretched or failed, and the joint depended on periarticular scar tissue for long-term stability.
Veterinary Specialty Center explains: TPLO changes the biomechanics of the knee so the joint can remain stable without relying on the damaged CCL.
Instead of replacing the torn ligament, it changes the mechanics of the knee entirely.
DVM360 confirms: TPLO alters the mechanical forces acting on the stifle, rendering the cranial cruciate ligament unnecessary.
Dr. Barclay Slocum first described TPLO in the early 1980s.
Veterinary Partner (VIN) notes that much research has been done since to refine the technique, and it has emerged as the most reliable technique for CCL disease management in dogs.
How TPLO differs from human ACL surgery
This is one of the most common points of confusion for owners.
In humans, ACL surgery typically involves replacing the torn ligament with a graft (taken from the patient's hamstring, patellar tendon, or a donor).
The new ligament is reconstructed to restore normal joint function.
TPLO does not reconstruct the CCL. It bypasses the need for a functioning CCL entirely by changing joint geometry.
Veterinary Specialty Center confirms: in people, ACL surgery replaces the torn ligament; in dogs, TPLO changes knee mechanics so the joint functions without the CCL.
This is why dogs cannot "re-tear" their CCL after TPLO there is no ligament replacement to fail. The stability provided by TPLO is structural and permanent.
What TPLO treats and who it is for
TPLO is used to treat cranial cruciate ligament (CCL) rupture the canine equivalent of the human ACL.
CCL rupture is the most common cause of hind limb lameness in dogs and costs US dog owners over $1 billion annually.
The ACVS recommends TPLO as the most commonly performed procedure for dogs over 60 lbs. It is also recommended for smaller dogs where long-term mechanical stability and minimal arthritis progression are priorities.

Frequently asked questions
Does TPLO stand for the same thing in all dogs?
Yes. The acronym and the procedure are the same regardless of breed, size, or the specific implant system used (Arthrex or Synthes).
The variation between cases is in the amount of tibial rotation required (based on the individual TPA), the plate size selected, and the post-operative protocol.
Is TPLO the same as TTA?
No. TTA (Tibial Tuberosity Advancement) is a different procedure with a similar goal both change knee biomechanics rather than replacing the CCL.
TTA advances the tibial tuberosity cranially rather than rotating the tibial plateau. They achieve knee stabilization through different geometric approaches.
Why is it called leveling if the bone is rotated?
The rotation of the tibial bone segment achieves the leveling.
When the proximal tibial segment is rotated, the angle of the tibial plateau changes it becomes less sloped, i.e., more level relative to the ground.
The procedure is named for the result (leveling) rather than the method (rotation).
Was TPLO invented for dogs?
Yes. TPLO was developed specifically for veterinary use in dogs in the early 1980s by Dr. Barclay Slocum.
It was developed because the canine stifle's anatomy and biomechanics differ significantly from the human knee particularly the steep tibial plateau angle that is uniquely problematic in dogs.
Why is TPLO preferred over other CCL surgeries for large dogs?
Large, active dogs generate higher joint forces than small dogs.
Extracapsular repair (lateral suture) provides stability through scar tissue formation adequate for small dogs but inadequate for the forces generated by large, active breeds.
TPLO provides bone-based mechanical stability that is not dependent on scar tissue, making it more durable and reliable for larger patients.

What is TPLO Surgery in Dogs?
TPLO (tibial plateau leveling osteotomy) is the most widely performed surgery for cranial cruciate ligament (CCL) rupture in dogs.
It is the procedure most commonly recommended by board-certified veterinary surgeons for medium and large dogs, and it has the most extensive published evidence base of any CCL repair technique.
Understanding what TPLO is, why it works, and what recovery involves helps owners make informed decisions and prepare for the process.
Quick answer: TPLO (tibial plateau leveling osteotomy) corrects CCL rupture by changing tibial plateau geometry to eliminate the shear force making the CCL unnecessary. A curved cut is made through the tibia, rotated to 5 degrees, and secured with a locking plate while the bone heals. Success rate is 90 to 95%.
Key takeaways
- TPLO stands for tibial plateau leveling osteotomy: it levels the tibial plateau through a bone cut to stabilize the stifle without relying on the damaged CCL
- TPLO corrects CCL rupture by eliminating the shear force the CCL resists: it changes the tibial plateau geometry so the joint is stable without a CCL
- The procedure achieves a post-operative tibial plateau angle of approximately 5 degrees: VCA confirms the tibial plateau is rotated until appropriately level (ideally 5 degrees), eliminating cranial tibial thrust
- TPLO has a 90 to 95% success rate: RCVS confirms 90 to 95% of dogs regain complete or near-complete function; 93% of owners report satisfaction at 12 months
- Recovery requires 8 to 12 weeks of activity restriction for bone healing; progressive return to full activity follows; muscle recovery takes up to 6 months
- TPLO is the most commonly recommended procedure for CCL rupture by ACVS surgeons in dogs over approximately 15 to 20 kg
The CCL and why it ruptures
The cranial cruciate ligament (CCL) is the equivalent of the human ACL in dogs.
It connects the femur (thigh bone) to the tibia (shin bone) inside the stifle (knee) joint and serves three primary functions:
- Preventing the tibia from sliding forward relative to the femur during weight bearing
- Limiting internal rotation of the tibia
- Preventing hyperextension of the stifle
Unlike most human ACL tears (which are acute traumatic events), CCL rupture in dogs is typically degenerative. The fibers weaken progressively over months to years before the ligament fails completely.
By the time complete rupture occurs, most of the fibers have already been compromised.
This is why the contralateral (opposite) CCL is also at risk -- the same degenerative process typically affects both stifles.
When the CCL ruptures, the tibial plateau's natural slope creates an unconstrained cranial shear force during weight bearing.
The femur slides down the tibial plateau, the tibia shifts forward, and the dog is in pain and unable to use the leg normally.
CCL rupture is one of the most common orthopedic injuries in dogs. High-risk breeds include Labrador Retrievers, Rottweilers, Staffordshire Terriers, Mastiffs, Newfoundlands, and German Shepherds.
Neutered dogs have a higher risk than intact dogs of the same breed.
How TPLO works: the biomechanical principle
The normal canine tibial plateau slopes downward from front to back at approximately 23 to 29 degrees (the tibial plateau angle, or TPA).
When the dog bears weight, this slope creates a cranial shear force -- the tibia tries to slide forward relative to the femur. In a normal stifle, the CCL resists this force.
When the CCL is absent, the force is unopposed and the joint is unstable.
TPLO does not attempt to restore the CCL. Instead, it eliminates the shear force entirely.
By rotating the tibial plateau to approximately 5 degrees, the joint surface becomes level enough that the patellar tendon -- rather than the CCL -- provides the stabilizing force during weight bearing.
The joint is mechanically stable without any ligament. The need for the CCL is eliminated by changing the geometry of the tibial plateau.
Dispomed confirms: TPLO addresses CCL rupture by altering the biomechanics of the stifle. The tibial plateau normally slopes downward; TPLO creates a flat or level plateau, decreasing sliding motion at this joint.
The TPLO procedure: step by step
Pre-operative planning
Before surgery, the dog is sedated and lateral stifle radiographs are taken.
The surgeon measures the TPA from these images and calculates the amount of rotation required to achieve the target post-operative TPA of approximately 5 degrees.
The surgeon also selects the appropriate saw blade radius and implant size based on these measurements and the dog's body weight.
Anesthesia and preparation
The dog is placed under general anesthesia. The surgical site is clipped and prepared with antiseptic solution. IV antibiotics (typically cefazolin) are given before the incision.
Joint inspection and meniscal assessment
The surgeon makes an incision over the medial aspect of the proximal tibia and performs a small arthrotomy (opening into the joint) to inspect the menisci.
Damaged meniscal tissue is removed at this stage.
Chewy confirms: during surgery, the joint is examined and the surgeon might remove damaged tissue before proceeding with the osteotomy.
The osteotomy
Using a specialized oscillating saw blade, the surgeon makes a curved (arcuate) cut through the proximal tibia at the level of the tibial plateau.
The radius of this cut is determined by the pre-operative planning.
Rotation
The cut bone segment (containing the tibial plateau) is rotated backward (caudally) by the calculated amount to achieve the target TPA.
VCA Animal Hospitals confirms: the top section of the tibia is rotated backward until deemed appropriately level -- typically 2 to 14 degrees, with 5 degrees as the ideal angle.
Plate fixation
A TPLO plate (a contoured locking plate) is secured to the tibia across the osteotomy using locking screws. The plate holds the rotated tibial plateau in position while the bone heals.
Closure
The joint capsule, fascia, subcutaneous tissue, and skin are closed in layers. The incision is bandaged.
Success rate and outcomes
RCVS Canine Cruciate Registry confirms: TPLO has a 90 to 95% success rate, with 90 to 95% of dogs regaining complete or near-complete function; 93% of owners reporting satisfaction at 12 months.
A 2013 study found that TPLO patients achieved 93% restoration of limb function at 1 year.
TPLO produces better long-term outcomes than lateral suture stabilization in most studies of large dogs, and similar long-term outcomes to TTA in comparable patient populations.
RCVS confirms: all dogs with CCL rupture are expected to develop at least some osteoarthritis, but this is reduced or delayed in dogs that have had surgical stabilization.
Recovery overview
- Weeks 0 to 2: crate rest, 5-minute bathroom leash walks only, e-collar on at all times
- Weeks 2 to 6: graduated leash walk increase, passive range-of-motion exercises
- Week 6: radiographic assessment of bone healing; activity increase if healing is progressing
- Weeks 8 to 12: final radiographic confirmation of bone healing; activity restrictions lifted if healing is confirmed
- Months 3 to 6: progressive return to full activity; muscle recovery continues

Frequently asked questions
Is TPLO the only surgery for CCL rupture in dogs?
No. The main alternatives are lateral suture stabilization (extracapsular repair), TTA (tibial tuberosity advancement), and CBLO (CORA-based leveling osteotomy). Lateral suture achieves good outcomes in dogs under approximately 35 pounds.
TTA produces similar long-term outcomes to TPLO in appropriately selected dogs. CBLO is used mainly for immature dogs and revision surgery cases.
Can a dog live without surgery for CCL rupture?
Small dogs (under 10 to 15 kg) sometimes stabilize adequately with conservative management (strict rest, weight management, joint support).
For most dogs over 15 kg, conservative management does not restore normal joint stability and the dog remains in pain with progressive arthritis.
Surgery is strongly recommended for most medium and large dogs.
How long does TPLO surgery take?
The procedure typically takes 1.5 to 2 hours. Bilateral simultaneous TPLO takes 3 to 4 hours.
Does the TPLO plate stay in permanently?
Yes, in most cases. The plate is not routinely removed after the osteotomy heals. It is removed if it causes complications (infection, implant irritation, failure).
What is the cost of TPLO surgery?
TPLO typically costs $3,500 to $6,000 per stifle depending on the facility, surgeon, geographic location, and the dog's size.
This typically includes the surgical procedure, anesthesia, hospitalization, implants, and the immediate post-operative period.

TPLO Plate Removal Recovery Guide
The TPLO plate is designed to stay in permanently. TPLO Info confirms that implants are designed to stay in for life they only need to be removed if a problem develops.
When plate removal is necessary, it is generally a less complex procedure than the original TPLO, and most dogs recover well.
Understanding when removal is needed, what recovery involves, and what to watch for helps owners navigate this phase confidently.
Quick answer: TPLO plate removal is performed when the plate causes infection, chronic pain, or implant failure. Recovery takes 6 to 12 weeks: 2 weeks for wound healing, 6 to 8 weeks for bone remodeling at the screw holes. Activity restriction for at least 6 weeks is required.
Key takeaways
- The TPLO plate does not routinely need to be removed: designed for permanent placement; removal is only indicated when it causes a problem
- The three main reasons for plate removal are: infection, chronic implant-associated pain causing ongoing lameness, and implant failure requiring revision
- Removal is only safe after the osteotomy has healed: typically 6 to 12 months post-TPLO once radiographs confirm bone union
- Recovery after plate removal takes 6 to 12 weeks: 2 weeks for wound healing; 6 to 8 weeks for bone remodeling
- Screw holes take 6 to 8 weeks to remodel: cortical defects temporarily weaken the bone; activity restriction prevents fracture
- Most dogs improve significantly after plate removal: implant irritation-related lameness typically resolves within weeks of removal
When is TPLO plate removal necessary?
Infection involving the implant (most common indication)
Bacterial biofilm colonizing the implant surface is the most common reason for plate removal.
Implant-associated infections often fail to resolve with antibiotics alone because bacteria form protective biofilms on the metal surface that antibiotics cannot penetrate adequately.
Once the osteotomy has healed typically at 6 to 12 months post-TPLO the plate can be safely removed, the bone is debrided, and the infection treated without the implant present.
Veterinary Orthopaedic and Mobility Center (VOMC) confirms that infection is the most common reason for implant removal.
For the full infection guide, see TPLO plate infection signs and treatment and when does a TPLO implant need to be removed due to infection.
Implant-associated pain without infection
Some dogs develop chronic lameness caused by the plate irritating surrounding soft tissues rather than infection.
The plate may irritate the periosteum, cause a local inflammatory reaction to the metal, or become symptomatic once the dog returns to activity.
TPLO Austin confirms: in rare instances, patients may simply be uncomfortable with the presence of the plate. In these cases, removal of the plate after bone healing will typically resolve the lameness.
Implant failure
If the plate bends, breaks, or screws loosen or fail, structural revision may be required.
Depending on the degree of bone healing at the time of failure, revision may involve plate removal and replacement, or removal alone once healing is sufficient.
TPLO Austin notes this is a very rare complication (under 1%) when activity restriction protocols are followed.
When is plate removal safe?
Plate removal requires confirmed radiographic bone healing the osteotomy must be fully bridged before the plate is removed.
The plate is the only structure holding the osteotomy in place; removing it before healing is complete risks the bone segments displacing.
Sustainablevet.org confirms: the plate can be removed once the bone is fully healed, typically 6 to 12 months after the operation.
SustainableVet's clinical guide for post-removal recovery confirms: removing hardware too early or in cases with incomplete healing increases the risk of delayed union or fracture. Careful radiographic assessment before surgery is essential.
The plate removal procedure
Plate removal is performed under general anesthesia. The original incision is reopened, the plate and screws are removed, and the wound is closed.
The procedure is significantly shorter and simpler than the original TPLO there is no bone cutting or rotation involved.
Vetplayas explains that the procedure involves removing the metal plate and screws from the tibia, with the wound closed in layers after removal.
If the indication was infection, the bone surface around the screw holes is debrided and the area flushed thoroughly. Bacterial culture is obtained to guide antibiotic selection.
Recovery timeline after TPLO plate removal
Weeks 1 to 2: wound healing
The incision heals similarly to the original TPLO incision. Pain management with NSAIDs and, in many cases, gabapentin is prescribed. The dog is confined and leash-walked only. Cold packing reduces post-surgical swelling.
SustainableVet's recovery guide confirms: the first 2 weeks focus on wound healing and pain management after surgery.
Weeks 2 to 8: bone remodeling
The primary recovery challenge after plate removal is the screw holes left in the tibia. These cortical defects temporarily reduce bone strength at those sites.
The bone requires 6 to 8 weeks to remodel and fill in these defects before normal activity loads can be tolerated.
SustainableVet's clinical guide confirms: bone typically requires 6 to 8 weeks post-plate removal to regain sufficient strength; high-impact activities must be limited during this critical period to prevent fracture.
Activity restrictions during recovery
- Leash walks only for the first 6 weeks minimum
- No running, jumping, stairs, or off-leash activity
- Rehabilitation exercises (PROM, sit-to-stand, controlled leash walks) as prescribed
- 8-week radiographs typically required to confirm screw hole remodeling before return to normal activity
Weeks 8 to 12: return to activity
If radiographs at week 8 confirm adequate bone remodeling, the surgeon approves progressive return to normal activity. Most dogs return to full activity by 10 to 12 weeks post-removal.
Complications of plate removal
Infection: the surgical site can develop a new infection during the removal procedure. Strict aseptic technique and sometimes antibiotic prophylaxis reduce this risk.
Fracture through screw holes: the cortical defects from screw removal temporarily weaken the bone. Activity restriction during the remodeling phase is essential to prevent fracture through these sites.
Delayed union: rare, but can occur if the bone at the surgical site is already compromised by chronic infection.
Incomplete resolution: if implant irritation was the indication and lameness persists after removal, additional investigation (nerve involvement, joint pathology) is warranted.

For the cost of plate removal, see TPLO plate removal cost.
Frequently asked questions
Does every TPLO dog eventually need the plate removed?
No. Most dogs retain the plate for life without problems. TPLO Info confirms that implants are designed to stay in place permanently.
Plate removal is only performed when there is a clinical indication: infection, persistent lameness from implant irritation, or implant failure.
How long does it take to recover from plate removal?
Generally 6 to 12 weeks, depending on the indication and the individual dog. Infection cases may take longer because bone debridement and antibiotic treatment add complexity.
Straightforward irritation-related removals with no infection typically have the shorter end of this timeline.
Is plate removal surgery serious?
It is a general anesthetic procedure and carries the standard risks of any surgical intervention, but it is significantly simpler than the original TPLO.
The main specific risk is fracture through the screw holes if activity restriction is not followed. Most dogs do well with appropriate post-operative care.
Can the plate be removed too early?
Yes, and this is dangerous. Removing the plate before the osteotomy has fully healed causes the bone segments to lose their only structural support, potentially leading to displacement or fracture.
Radiographic confirmation of bone healing is mandatory before plate removal is scheduled.
Will my dog need another round of rehabilitation after plate removal?
Typically a milder version, yes controlled leash walks, PROM if stiffness is present, and gradual return to activity over 6 to 12 weeks.
Dogs that had ongoing lameness from implant irritation often improve quickly once the plate is removed, but the bone still requires the restricted activity period regardless of how well the dog feels.

TPLO Recovery Exercises for Dogs
Learn effective TPLO recovery exercises for dogs to ensure safe healing and regain mobility after surgery.
TPLO recovery exercises for dogs are essential to help your pet regain strength and mobility after surgery. Tibial Plateau Leveling Osteotomy (TPLO) is a common procedure to repair cruciate ligament injuries, but proper rehabilitation is key to success.
This article explains the best exercises for dogs recovering from TPLO surgery. You will learn safe ways to support your dog's healing, improve joint function, and avoid complications during recovery.
What is TPLO surgery and why is recovery important?
TPLO surgery stabilizes a dog's knee joint after a torn cranial cruciate ligament. The procedure changes the angle of the tibia to reduce stress on the ligament. Recovery is critical because the joint needs time to heal and regain normal function.
Without proper recovery exercises, dogs may develop stiffness, muscle loss, or abnormal gait. Controlled rehabilitation helps restore strength and prevents long-term problems.
- TPLO purpose: TPLO surgery corrects knee instability caused by ligament tears, allowing dogs to walk and run without pain.
- Healing time: Bone healing after TPLO usually takes 8 to 12 weeks, during which exercises must be carefully managed.
- Muscle maintenance: Recovery exercises prevent muscle wasting and improve joint support for better mobility.
- Preventing stiffness: Gentle movement reduces joint stiffness and promotes healthy cartilage and ligament healing.
Following a structured exercise plan after TPLO surgery is essential for your dog's full recovery and long-term joint health.
When can I start TPLO recovery exercises for my dog?
Starting recovery exercises depends on your veterinarian's advice and your dog's healing progress. Typically, gentle exercises begin within a few days after surgery, progressing gradually over weeks.
Early movement helps reduce swelling and maintain circulation, but high-impact activities must be avoided until the bone fully heals.
- Initial rest period: Dogs usually require strict rest for the first 1 to 2 weeks to allow initial bone healing.
- Vet approval: Always consult your vet before starting any exercise to ensure it is safe for your dog's stage of recovery.
- Gradual progression: Exercises increase in intensity and duration over 8 to 12 weeks based on healing and pain levels.
- Signs to watch: Stop exercises if your dog shows limping, swelling, or pain, and contact your vet immediately.
Following a vet-approved timeline for exercises ensures your dog recovers safely and avoids setbacks.
What are the best passive TPLO recovery exercises for dogs?
Passive exercises involve moving your dog's leg without active muscle use. These help maintain joint flexibility and reduce stiffness early in recovery.
They are safe to perform soon after surgery and do not stress the healing bone or ligament.
- Range of motion: Gently bend and straighten the knee joint within a pain-free range to keep it flexible.
- Massage therapy: Light massage around the surgical site improves circulation and reduces swelling.
- Cold therapy: Applying cold packs after passive exercises reduces inflammation and discomfort.
- Leg lifts: Carefully lift and lower the leg to encourage gentle movement without weight bearing.
These passive exercises prepare your dog for more active rehabilitation phases while protecting the surgical repair.
Which active exercises help dogs regain strength after TPLO?
Active exercises require your dog to use muscles and support weight on the operated leg. These are introduced gradually to rebuild strength and coordination.
They improve muscle tone, joint stability, and overall limb function as healing progresses.
- Leash walking: Short, controlled walks on a leash encourage weight bearing and muscle use without overexertion.
- Sit-to-stand: Encouraging your dog to sit and stand repeatedly strengthens thigh muscles supporting the knee.
- Balance exercises: Using a wobble board or soft surface challenges your dog's balance and joint control.
- Controlled stairs: Slowly climbing and descending stairs helps improve joint range and muscle power.
Active exercises should be supervised and adjusted based on your dog's comfort and recovery stage.
How can hydrotherapy support TPLO recovery in dogs?
Hydrotherapy uses water to provide low-impact exercise that supports healing after TPLO surgery. The buoyancy reduces joint stress while allowing muscle strengthening.
This therapy is often recommended by vets and rehabilitation specialists to speed recovery and improve outcomes.
- Water treadmill: Walking on a submerged treadmill helps build strength with less pain and swelling.
- Swimming sessions: Swimming provides full-body exercise without weight bearing on the knee joint.
- Hydro massage: Water jets can massage muscles and reduce stiffness around the surgical area.
- Temperature control: Warm water improves circulation and relaxes muscles during therapy.
Hydrotherapy is a safe and effective way to enhance recovery when combined with other rehabilitation exercises.
What precautions should I take during TPLO recovery exercises?
Safety is critical when performing recovery exercises after TPLO surgery. Incorrect or excessive activity can cause pain, swelling, or damage to the surgical repair.
Following guidelines and monitoring your dog closely helps prevent complications and ensures steady progress.
- Follow vet instructions: Always adhere to your veterinarian's exercise plan and timelines for safe recovery.
- Monitor pain signs: Watch for limping, whining, or reluctance to move, which indicate discomfort or injury.
- Limit off-leash activity: Avoid running, jumping, or rough play until fully healed to protect the knee joint.
- Use supportive devices: Consider braces or slings if recommended to assist mobility and reduce strain.
Taking these precautions helps your dog heal efficiently and return to normal activity safely.
How long does full TPLO recovery take with exercises?
Full recovery from TPLO surgery usually takes 3 to 6 months with proper rehabilitation exercises. The timeline varies depending on the dog's age, size, and overall health.
Consistent exercise and veterinary follow-up are essential to achieve the best outcome and prevent future injuries.
- Bone healing: The bone typically heals within 8 to 12 weeks, allowing gradual increase in exercise intensity.
- Muscle rebuilding: Muscle strength improves over several months with regular active exercises.
- Joint function: Full joint mobility and stability may take up to 6 months to restore completely.
- Long-term care: Maintaining a healthy weight and regular low-impact exercise helps prevent re-injury after recovery.
Patience and commitment to the exercise plan are key to your dog's successful TPLO recovery and long-term mobility.
Conclusion
TPLO recovery exercises for dogs are vital to help your pet heal safely and regain full function after surgery. Starting with passive movements and progressing to active exercises supports bone healing and muscle strength.
Consult your veterinarian regularly and follow a structured rehabilitation plan to ensure the best outcome. With proper care and patience, your dog can enjoy a healthy, active life after TPLO surgery.
FAQs
How soon after TPLO surgery can my dog start walking?
Most dogs begin short, controlled leash walks within 1 to 2 weeks after surgery, depending on veterinary advice and healing progress.
Can I do TPLO recovery exercises at home?
Yes, many passive and active exercises can be safely done at home following your vet's instructions and supervision.
Is hydrotherapy necessary for TPLO recovery?
Hydrotherapy is not mandatory but highly beneficial for low-impact strengthening and faster recovery when available.
What signs mean I should stop exercises and call my vet?
Stop exercises if your dog shows increased limping, swelling, pain, or reluctance to move and contact your veterinarian promptly.
How long do I need to restrict my dog's activity after TPLO?
Activity restriction usually lasts 8 to 12 weeks, gradually easing as bone healing progresses and exercises increase.

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.

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.

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.

Dog Toe Tapping After TPLO Surgery Explained
Learn why your dog may tap toes after TPLO surgery, what it means, and how to support recovery with expert veterinary advice.
After your dog undergoes TPLO surgery, you might notice unusual behaviors like toe tapping. This can be worrying if you do not understand why it happens or what it means for your dog's recovery. Toe tapping after TPLO surgery is a common sign that your dog is adjusting to changes in limb use and nerve sensation.
This article explains what causes toe tapping after TPLO surgery, how to recognize normal versus concerning signs, and what steps you can take to help your dog heal properly. You will learn about the healing process, pain management, and when to contact your veterinarian for further care.
Why does my dog tap toes after TPLO surgery?
Toe tapping after TPLO surgery often results from nerve irritation or changes in limb sensation. The surgery alters the knee joint mechanics, which can temporarily affect how your dog feels and moves the leg. This tapping is usually a sign your dog is testing the limb and regaining control.
Understanding the cause helps you differentiate normal recovery behavior from signs of complications.
- Nerve sensitivity: Surgery can irritate nerves around the knee, causing your dog to tap toes as a response to altered sensations or mild discomfort.
- Muscle weakness: After TPLO, muscles supporting the leg may be weak, leading to unsteady foot placement and toe tapping during weight shifting.
- Proprioception changes: The dog's sense of limb position may be temporarily impaired, causing tapping as the brain relearns limb control.
- Habitual behavior: Some dogs develop toe tapping as a habit during the recovery phase when adjusting to new limb mechanics.
Most toe tapping is a normal part of the healing process and improves as nerve function and muscle strength return.
How long does toe tapping last after TPLO surgery?
The duration of toe tapping varies depending on the individual dog and the extent of surgery. Typically, toe tapping decreases as healing progresses over weeks to months. Monitoring your dog's behavior helps track recovery.
Knowing the expected timeline can ease your concerns and guide you when to seek veterinary advice.
- Early recovery phase: Toe tapping is most common in the first 2 to 4 weeks post-surgery when nerves and muscles are healing.
- Mid recovery phase: Between 4 to 8 weeks, tapping should reduce as strength and sensation improve with physical therapy.
- Late recovery phase: After 8 weeks, toe tapping usually disappears, indicating good nerve and muscle recovery.
- Persistent tapping: If toe tapping continues beyond 3 months, it may signal complications requiring veterinary evaluation.
Regular follow-ups with your vet ensure your dog's recovery stays on track and toe tapping resolves appropriately.
Is toe tapping after TPLO surgery painful for my dog?
Toe tapping itself is not usually painful but may indicate mild discomfort or nerve irritation. Your dog might tap toes to relieve sensations or test limb stability. Proper pain management during recovery minimizes discomfort and promotes healing.
Recognizing pain signs helps you provide better care and communicate effectively with your veterinarian.
- Mild discomfort: Nerve healing can cause tingling or mild pain, leading to toe tapping as a coping mechanism.
- Pain signs: Excessive licking, whining, or limping along with tapping may indicate pain needing treatment.

While toe tapping is often normal, some signs indicate complications requiring veterinary care. Recognizing these signs early prevents worsening problems and supports your dog’s recovery.
Knowing when to seek help ensures your dog receives timely treatment for any issues.
- Increased tapping intensity: Sudden or worsening toe tapping may signal nerve damage or pain needing evaluation.
- Swelling or redness: Signs of infection or inflammation around the surgical site require immediate veterinary attention.
- Persistent limping: If your dog avoids putting weight on the leg for more than a few days, it may indicate complications.
- Behavior changes: Excessive licking, biting at the leg, or signs of distress suggest pain or nerve problems needing assessment.
Contact your veterinarian promptly if you notice these signs to prevent long-term damage.
How can physical therapy help with toe tapping after TPLO surgery?
Physical therapy plays a key role in reducing toe tapping by improving muscle strength, coordination, and nerve function. Tailored exercises help your dog regain normal limb use and reduce abnormal movements.
Incorporating therapy into recovery accelerates healing and enhances your dog’s quality of life.
- Strength building: Targeted exercises increase muscle tone around the knee, stabilizing the joint and reducing tapping.
- Proprioception training: Activities that improve limb position sense help your dog control foot placement better.
- Pain reduction: Gentle massage and stretching relieve nerve irritation contributing to tapping behavior.
- Improved mobility: Controlled movement prevents stiffness and encourages normal gait patterns during recovery.
Work with a veterinary rehabilitation specialist to design a safe and effective therapy plan for your dog.
Conclusion
Toe tapping after TPLO surgery is a common behavior linked to nerve healing, muscle weakness, and changes in limb sensation. It usually decreases over weeks as your dog recovers strength and coordination. Understanding this helps you support your dog’s healing process with patience and proper care.
Always monitor your dog’s behavior closely and follow your veterinarian’s advice on pain management and physical therapy. Promptly report any worsening signs to ensure your dog heals safely and returns to normal activity.

Why Is My Dog's Leg Clicking After TPLO Surgery?
Wondering why your dog’s leg is clicking after TPLO surgery? Learn common causes, when to worry, and what to expect during recovery
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

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.

How Long Does TPLO Surgery Take?
Learn how long TPLO surgery takes, what to expect during the procedure, and recovery timelines for your dog's knee surgery.
"Failure rate" is used loosely when owners discuss TPLO, which can cause significant confusion. A complication is not the same as a failure.
Understanding what the published data actually shows and distinguishing minor complications from true surgical failures gives owners a much clearer picture of what to expect.
Quick answer: The overall TPLO complication rate is 10 to 34% across studies; most are minor. Major complications requiring reoperation occur in 2 to 7%. Infection is the most common major complication. Long-term good outcomes are reported in 90 to 93% of dogs.
Key takeaways
- Overall complication rate is 10 to 34% across published studies; most complications are minor and resolve without additional surgery
- Major complication rate requiring reoperation is 2 to 7%: a 1,000-dog study found 14.8% overall with 6.6% major complications
- SSI is the most common major complication: 2.9% to 25.9% across studies; giant breeds over 50 kg are at highest risk
- Small dogs under 15 kg have significantly lower complication rates: 4.44% in one 90-dog study, with no revisions
- Good to excellent long-term outcomes in 90 to 93% of dogs: the complication rate does not equal the failure rate
- Surgeon experience is the most modifiable risk factor: complication rates are consistently lower at high-volume specialty centers with board-certified surgeons
Defining "failure" vs. "complication"
This distinction is critical for interpreting the literature and for setting owner expectations accurately.
Complication: any deviation from the expected post-operative course. This includes minor findings like superficial wound dehiscence, mild swelling, or radiographic evidence of delayed osteotomy healing with no clinical signs. Many publications include these minor events in their complication rates.
Major complication: an event requiring additional surgical intervention or causing extended lameness. Major complications represent the subset of complications that meaningfully affect recovery and outcome.
Failure: the most restrictive definition surgery that did not achieve its goal of stifle stabilization, resulting in persistent instability and requiring revision with a different technique. True failure in this sense is uncommon after TPLO.
What published complication data shows
Overall complication rates
Vetamac confirms: complication rates following TPLO surgery range from 14% to 34%, with less than 10% of cases requiring a second surgery.
PMC (intraoperative bacterial culture study) confirms: the complication rate of TPLO varies between 10% and 34%, with 2 to 4% requiring surgical revision.
Today's Veterinary Practice reports a 14.8% complication rate in 1,000 TPLO patients (6.6% major — requiring repeat surgery or extended lameness), including 2.8% late meniscal injury and 6.6% infections.
Infection rates
Infection is the most common major complication and the one with the greatest variation by dog size and surgical setting.
PMC confirms: SSI rate after TPLO is reported to be 2.9% to 25.9% across studies, which is higher than other clean orthopedic surgeries (2.0 to 6.7%).
Surgical site infection rates of 21.3% to 25.9% have been reported specifically for giant-breed dogs weighing over 50 kg.
The implant removal rate due to infection is 3 to 7.4% per published literature (PMC PRP study; ResearchGate implant removal study).
Complication rates by dog size
Dog size is a consistent predictor of complication risk.
PLOS One retrospective (90 dogs under 15 kg): overall complication rate 4.44%, with no complications requiring surgical revision.
The study confirms: the complication rate in dogs under 15 kg is less than that historically reported in heavier dogs.
PubMed retrospective (small and medium dogs, 2.0 and 2.7 mm plates): overall complication rate 36%.
The most common complications were radiographic evidence of delayed healing (9%), patellar tendon thickening (8%), and tibial tuberosity fracture (6%). Only 7% of complications were major.
PLOS One confirms: the TPLO complication rates range from 10% to 34% and vary in severity from swelling and bruising to fractures and osteomyelitis.
Implant-related complications reportedly occur in under 10% of all TPLO procedures.
Long-term success rates
Complication rates must be interpreted alongside long-term success rates.
The retrospective cohort study comparing TPLO, Tightrope, and TTA found: function greater than 1 year after surgery was 93.1% for TPLO, 92.7% for Tightrope, and 89.2% for TTA.
SustainableVet.org confirms: good to excellent long-term outcomes are achieved in 90.4% of patients up to 6.8 years after TPLO surgery; 80 to 90% of owners are satisfied with their dog's long-term recovery.
A dog can have a complication even a significant one like an infection and still achieve a good long-term outcome after the complication is resolved.
The complication rate and the long-term success rate address different aspects of the outcome.
Factors that affect complication and failure rates
Surgeon experience and volume
This is the most consistently cited modifiable risk factor. High-volume specialty centers and board-certified surgeons consistently report lower complication rates than general practitioners performing occasional TPLO procedures.
Surgical efficiency, technique precision, and post-operative protocol standardization all contribute.
Dog size and body weight
Larger dogs generate higher joint forces, have larger dead space at the surgical site, and place more mechanical demand on the implant during healing.
These factors contribute to the higher complication rates seen in large and giant breeds.
Excessive tibial plateau angle (TPA)
Dogs with TPA above 35 degrees (excessive TPA, or eTPA) have higher complication rates.
Today's Veterinary Practice notes: owner-perceived outcome was superior for eTPA group dogs when TPLO resulted in TPA of 14 degrees or less compared to those with TPA greater than 14 degrees.
Postoperative complications were more common in dogs with eTPA.
Post-operative activity restriction compliance
Dogs that are over-active during recovery have higher rates of implant complications, seroma formation, and wound complications.
Strict adherence to the prescribed restriction protocol is the owner's primary contribution to reducing complication risk.
For the complications overview, see 15 common complications after TPLO surgery in dogs. For the infection signs guide, see TPLO plate infection signs and treatment.
For the long-term outcomes guide, see long-term outcomes of TPLO surgery. For the plate removal guide, see TPLO plate removal recovery guide.
Frequently asked questions
What is the TPLO failure rate?
Depends on how "failure" is defined. If failure means any complication: 10 to 34% across studies. If failure means major complications requiring surgery or causing extended lameness: 2 to 7%.
If failure means persistent instability requiring revision with a different technique: uncommon and not consistently reported across large series.
Is TPLO safe for large breed dogs?
Yes, but with a higher complication risk than small dogs. Vetamac confirms: for large breeds, TPLO is still the gold standard, providing better long-term stability than alternatives.
The higher complication rate in large dogs reflects the greater mechanical demands and surgical challenges, not a fundamental unsafety of the procedure.
What percentage of TPLO dogs need a second surgery?
Across published studies, 2 to 10% require a second surgical intervention. Most second surgeries address infection (requiring plate removal), late meniscal tears (requiring partial meniscectomy), or implant complications.
Does my dog's vet experience affect failure rate?
Yes, substantially. Surgeons performing fewer than a set number of TPLO procedures per year have higher complication rates than high-volume specialists.
This is one reason referral to a board-certified orthopedic surgeon (ACVS diplomate) is recommended for TPLO.
If my dog has a complication, does that mean the TPLO failed?
Not necessarily. Many dogs who develop complications including infections requiring plate removal still achieve good to excellent long-term function after the complication is resolved.
The complication rate and the long-term outcome are different measures.

How Long Does Swelling Last After TPLO Surgery
Find out how long swelling lasts after TPLO surgery, what’s normal, and when to call your vet for possible infection or complications.
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 fluid buildup guide, see fluid buildup after TPLO surgery in dogs. For the ankle swelling guide, see ankle swelling after TPLO surgery in dogs.
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.

Dog Not Peeing After TPLO Surgery: Causes & Care
Learn why your dog may not pee after TPLO surgery and how to manage this common post-op issue safely and effectively.
It is common to notice changes in a dog's urination pattern in the first 24 to 48 hours after TPLO surgery.
Most of these changes are temporary and related to the effects of anesthesia, pain medications, and reduced mobility.
However, not urinating at all for more than 12 to 24 hours is a clinical concern that requires prompt veterinary contact.
Quick answer: Reduced urination in the first 12 to 24 hours after TPLO is usually caused by anesthesia effects, opioid medications, pain, or stress. Contact your vet immediately if your dog has not urinated within 12 hours post-surgery, or if you observe straining, vocalization, or abdominal distension.
Key takeaways
- Reduced urination in the first 12 to 24 hours is normal: anesthesia suppresses bladder awareness and opioids reduce the sensation of fullness
- Contact your vet if no urination occurs within 12 hours post-surgery: this is the critical threshold, per published veterinary guidance do not wait
- Straining, vocalizing, or abdominal swelling requires same-day veterinary evaluation: these signs suggest urinary retention requiring catheterization
- Opioid pain medications are the most common pharmacological cause: they reduce bladder filling sensation and sphincter tone in some dogs
- Surgical catheterization during the procedure may temporarily affect urination for 12 to 24 hours after catheter removal
- Increased water intake without urination is particularly concerning: it suggests the dog is producing urine but cannot eliminate it a potential retention emergency
Why dogs may not urinate normally after TPLO
Anesthesia effects
General anesthesia suppresses the entire nervous system, including the neural pathways that signal bladder fullness and initiate voiding.
As anesthetic agents clear over the first 12 to 24 hours, normal bladder signaling gradually returns.
Most dogs produce less urine during anesthesia because of reduced blood pressure and fluid redistribution.
When fluid therapy resumes and hydration normalizes after surgery, urine production increases but the dog must also have recovered enough neurological function to void normally.
Opioid pain medications
Opioid analgesics (hydromorphone, morphine, buprenorphine) prescribed after TPLO affect urination in two main ways.
They reduce the perception of bladder fullness, so the dog does not signal readiness to urinate as promptly as usual.
In some dogs they also increase urethral sphincter tone, making voiding more difficult.
JustAnswer veterinary consultation confirms: opioids can cause urinary retention by relaxing or altering bladder muscles, making it hard for the dog to pee.
This effect is temporary and typically resolves as opioid dosing decreases over the first 48 to 72 hours.
Pain and reluctance to posture
Urination requires the dog to posture squatting or lifting a leg both of which require hindlimb use and core stability that are painful in the first days after TPLO.
A dog that finds posturing too painful may suppress the urge to urinate or produce only small amounts.
Providing a non-slip surface, a low slung outdoor space (not steps or slopes), and supporting the dog with a belly sling during outdoor trips reduces posturing pain and encourages normal urination.
Surgical catheterization
A urinary catheter is often placed during TPLO surgery to drain the bladder, keep the surgical field dry, and prevent accidents during the procedure.
After catheter removal, some dogs take 12 to 24 hours to resume normal voiding patterns as the urethra recovers from catheter placement and the bladder regains normal tone.
Stress and unfamiliar environment
Dogs in pain, in an unfamiliar post-surgical environment, and wearing an E-collar may suppress urination due to stress.
Stress-related urinary suppression is temporary and usually resolves as the dog settles into the home recovery environment.
Normal urination expectations after TPLO
Most dogs urinate at least once within 6 to 12 hours of returning home from surgery. By 24 hours, most dogs have urinated multiple times.
The SustainableVet.org dog-not-peeing guide confirms: if your dog does not pee within 24 hours post-surgery, contact your veterinarian immediately to rule out complications.
The published veterinary guidance for emergency contact is: no urination within 12 hours post-surgery contact your vet.
Signs that require immediate veterinary contact
Contact your veterinarian same-day or go to an emergency clinic if you observe:
No urination at all for 12 or more hours after surgery: this is the key threshold do not wait to see if it resolves
Straining or crying during urination attempts: the dog is trying to urinate but cannot produce a stream classic urinary retention sign
Abdominal distension: the belly feels full or tense; this suggests a distended bladder (urinary retention emergency)
Drinking water but producing no urine: urine is being produced but cannot be eliminated urgent
Vomiting or lethargy alongside no urination: systemic signs accompanying urinary retention indicate a more serious emergency
Urinary retention: what happens and how it is treated
Urinary retention means the bladder cannot empty. The bladder fills progressively and becomes painful, distended, and eventually at risk of rupture if unrelieved. Prolonged retention also causes back-pressure on the kidneys.
Treatment depends on the cause:
- Catheterization: gentle placement of a urinary catheter to drain the bladder provides immediate relief and allows the bladder to recover normal tone
- Pain management adjustment: if opioid-induced retention is suspected, the analgesic protocol may be modified
- Bethanechol: a parasympathomimetic drug that stimulates bladder contraction; sometimes used in dogs with neurogenic urinary retention
- Urinalysis and culture: if infection is suspected alongside retention
Home care to encourage urination
- Scheduled outdoor trips every 2 to 4 hours for the first 24 to 48 hours
- Non-slip surface outdoors pain and weakness increase slipping risk
- Gentle belly-sling support to reduce posturing pain (fold a large towel under the belly and lift slightly)
- Quiet, calm outdoor environment stressed dogs suppress urination
- Adequate pain control contact your vet if your dog is vocalizing or reluctant to move; these are signs pain medication is insufficient
- Monitor and record each urination: time, approximate volume, any straining or discomfort

Frequently asked questions
How long after TPLO surgery should my dog urinate?
Most dogs urinate within 6 to 12 hours of returning home from surgery. Contact your veterinarian if no urination has occurred within 12 hours.
Do not wait for the 24-hour mark if the dog is straining, vocalizing, or appears uncomfortable.
My dog is drinking water but not peeing at all. Is this an emergency?
Yes. A dog that is drinking and producing urine but cannot eliminate it (retention) needs same-day veterinary evaluation. A distended bladder is painful and can rupture.
Do not manage this at home contact your vet immediately.
Can opioid pain medications cause urinary retention?
Yes. Opioids are a recognized cause of urinary retention in both humans and dogs.
If your dog was urinating normally before surgery and stops after receiving opioid medications, this is likely a contributing factor.
Contact your vet the analgesic protocol may be modified without eliminating pain management.
What does a catheter placement during surgery do to urination afterward?
Urinary catheters are placed during TPLO to drain the bladder and keep the surgical field dry.
After catheter removal, some dogs take 12 to 24 hours to resume normal voiding as the urethra recovers.
This is expected and not a cause for alarm, as long as the dog urinates within the normal timeframe.
Is it safe to give my dog extra water if they're not peeing?
Normal hydration is essential and should be maintained. Do not restrict water.
However, if the dog is drinking normally and still not producing urine, this increases the urgency of veterinary contact rather than reducing it.

When Can Dogs Resume Agility Training Post-TPLO?
Learn when and how to safely resume dog agility training after TPLO surgery. Get expert-backed recovery tips, rehab steps, and risk precautions
Returning an agility dog to sport after TPLO surgery requires more than standard recovery. The standard 8 to 12 week bone healing protocol restores a dog to normal household function.
Returning to agility -- a high-impact sport involving jumping, sharp turns, weave poles, and contact obstacles -- requires a further 4 to 6 months of structured conditioning on top of that foundation.
Quick answer: Most agility dogs return to training 7 to 9 months post-TPLO. The Balanced Dog confirms 80% returned before 9 months (average 7.5 months). Bone healing at 8 to 12 weeks is the starting point. Return to sport requires muscle symmetry, pain-free movement, and a graduated protocol with vet clearance.
Key takeaways
- The return-to-agility timeline averages 7 to 9 months: The Balanced Dog confirms 80% returned before 9 months, average 7.5 months; 3 to 6 months reflects light training, not full competition
- Bone healing at 8 to 12 weeks is the starting point, not the endpoint: high-impact agility may require 4 to 6 more months; healed bone does not mean rebuilt muscle
- Agility-specific demands require agility-specific conditioning: jumping, tight turns, weave poles, and contacts generate forces far greater than walking; the dog must be conditioned for these before returning
- All dogs with agility return goals need a return-to-sport protocol: it adds sport-specific movement, progressive jumping, and fitness benchmarks beyond the standard recovery protocol
- Veterinary clearance at each phase is non-negotiable: vet or surgeon clearance is required before resuming training; no benchmark should be self-assessed
- Not all dogs will reach pre-surgery performance: most regain significant function but some need training changes to reduce joint stress
Why agility is a higher bar than normal recovery
Normal TPLO recovery targets return to household mobility: walking, light running, stairs, and play. Agility sport involves:
- Jumping: impact forces on landing of 2 to 3 times body weight
- Tight turns at speed: high lateral shear forces on the stifle
- Weave poles: rapid lateral flexion and extension
- Contact obstacles (A-frame, dog walk, teeter): climbing and controlled descent under dynamic loading
Each of these demands requires not just healed bone but fully rebuilt muscle, coordinated neuromuscular control, and joint proprioception. These take months to restore after TPLO.
SustainableVet.org confirms: dogs in sports or agility should reintroduce jumps and running only after veterinary clearance; swimming or uphill walking maintains muscle tone during the conditioning phase.
The return-to-sport timeline
Phase 1: bone healing (weeks 0 to 12)
Standard TPLO recovery. Strict confinement, graduated leash walking, and passive range-of-motion exercises. No running, jumping, or agility activity of any kind.
Radiographic bone healing is confirmed at the 8 to 12 week recheck. This is the gate that opens Phase 2.
Phase 2: rebuilding foundation fitness (months 3 to 5)
After bone healing is confirmed, the focus shifts to rebuilding the muscle mass and neuromuscular coordination that atrophied during the restriction period.
Activities during Phase 2:
- Progressive leash walking with duration increasing weekly
- Hydrotherapy (underwater treadmill) for muscle building without joint impact
- Hill walking (controlled inclines) to load the hip extensors and stifle stabilizers
- Balance and proprioception work (wobble boards, cavaletti poles)
- Core strengthening exercises
TPLO Info confirms: overall return to agility takes around 3 to 6 months; this period of rebuilding is what fills the gap between bone healing and sport re-entry.
Phase 3: sport-specific conditioning (months 5 to 7)
Once the dog has rebuilt baseline fitness, sport-specific conditioning begins. This is distinct from the standard recovery protocol.
Activities:
- Controlled jumping starting very low (4 inches for a dog that jumps 24 inches in competition) and increasing progressively over 6 to 8 weeks
- Slow figure-8 work and curved running to restore stifle lateral mechanics
- Individual weave pole work at slow speed before full weave sequence
- Contact obstacle approach and exit work at slow, controlled speed
- Video gait assessment to identify any asymmetry or compensation patterns
Petcarepartners.co confirms: most vets suggest a waiting period of 4 to 6 months for running and fetch; for agility, add a further structured sport-specific phase on top of this.
Phase 4: return to full competition (months 7 to 9+)
Full competition resumption follows veterinary clearance of the sport-specific conditioning phase. The criteria for clearance include:
- Pain-free movement through full range of stifle motion
- Muscle symmetry (thigh circumference equal bilaterally)
- Confident single-leg weight bearing during agility-specific movements
- No lameness following a full practice session
- Surgeon clearance based on physical and radiographic assessment
The Balanced Dog confirms: it typically takes 7 to 9 months to return to sport; 80% of dogs returned to agility before 9 months with a good rehabilitation and return-to-sport program.
Factors that affect the return timeline
Dog's age: younger dogs (under 4 years) typically rebuild muscle faster than older dogs. Senior dogs may take 10 to 12 months or longer.
Dog's pre-surgical fitness: well-conditioned sport dogs with strong baseline muscle mass rebuild faster than deconditioned dogs. Body condition score at the time of surgery matters.
Adherence to the restriction protocol: dogs that were overactive during weeks 1 to 6 may have developed micro-complications or delayed healing that shifts the timeline.
Concurrent meniscal tear: dogs that had a meniscal tear treated at the time of TPLO may need additional time, particularly if a late meniscal tear occurs during the return-to-sport phase.
Bilateral CCL disease: dogs with CCL rupture on the second side during or after recovery for the first require the full protocol on the second side before bilateral agility work resumes.
SustainableVet.org confirms: average recovery time to agility is about seven months; some dogs start controlled activity at six months, while others take up to two years.
Using a certified canine rehabilitation therapist
For agility dogs, professional rehabilitation is strongly recommended rather than a home-only protocol. Certified canine rehabilitation practitioners (CCRPs) provide:
- Biomechanical gait analysis to detect compensatory movement patterns before return to sport
- Underwater treadmill protocols calibrated to the specific demands of agility
- Sport-specific functional testing to determine readiness
- Individualized return-to-sport programs
The Balanced Dog confirms: surgery is just the start; a good-quality rehabilitation and return-to-sport program is instrumental in giving the dog the best chance at returning to competitive agility.

Frequently asked questions
My agility dog had TPLO 6 months ago and is moving well. Can she start jumping?
Six months is within the average return-to-sport window but requires veterinary assessment before starting jumping.
The criteria -- muscle symmetry, pain-free full range of motion, confident single-leg weight bearing -- must be met and confirmed by your vet or rehabilitation therapist before any jumping begins.
Do not self-assess readiness.
Will my dog ever compete at the same level as before TPLO?
Many dogs do return to pre-injury competitive levels, especially those with strong pre-surgical conditioning and an excellent rehabilitation program.
SustainableVet.org confirms most dogs regain significant function and can participate in agility, though not all will reach pre-injury performance levels. The Balanced Dog study confirms 80% returned before 9 months.
Should I lower my dog's jump height after TPLO?
Discuss with your vet. Some dogs perform best at a jump height one level below their pre-surgery height to reduce cumulative joint loading. Others return to their full height without adjustment.
This is an individual decision based on the dog's age, size, arthritis level, and post-recovery movement quality.
Can I use a FitPaws or conditioning equipment at home?
Yes -- proprioception and balance equipment (wobble boards, FitPaws equipment, balance pads) is appropriate during Phase 2 and Phase 3 under the direction of your rehabilitation therapist.
These tools help rebuild the neuromuscular coordination needed for agility-specific movements. Always use on non-slip flooring.
What happens if my dog tears the other CCL during agility return?
Bilateral CCL disease is common (30 to 40% of dogs develop it). If the second stifle becomes symptomatic during the return-to-agility phase, the rehabilitation program pauses and the second stifle is assessed.
The return-to-agility timeline resets based on the second surgery date. Most dogs with bilateral TPLO can still return to agility.

Lameness After TPLO Surgery in Dogs
Learn about causes, diagnosis, and treatment of lameness after TPLO surgery in dogs to help your pet recover fully.
Lameness after TPLO surgery in dogs is a common concern for pet owners. TPLO, or Tibial Plateau Leveling Osteotomy, is a surgical procedure to stabilize the knee after a cranial cruciate ligament rupture. Sometimes, dogs show limping or difficulty walking after this surgery, which can worry owners.
This article explains why lameness happens after TPLO surgery, how veterinarians diagnose it, and what treatments help dogs recover. You will learn what signs to watch for and how to support your dog’s healing process effectively.
What causes lameness after TPLO surgery in dogs?
Lameness after TPLO surgery can arise from several factors. Understanding these causes helps you recognize if your dog’s limping is normal or needs veterinary attention. Some causes are related to surgery recovery, while others may indicate complications.
- Postoperative pain: Pain from surgery and inflammation can cause limping during the first weeks, which usually improves with pain management and rest.
- Soft tissue swelling: Swelling around the knee joint after surgery can limit movement and cause discomfort, leading to temporary lameness.
- Implant irritation: The metal plate and screws used in TPLO can sometimes irritate surrounding tissues, causing discomfort and limping.
- Infection risk: Surgical site infections can cause pain, swelling, and lameness, requiring prompt veterinary care.
Other causes include meniscal injury, implant failure, or improper bone healing. Monitoring your dog closely after surgery helps detect these issues early.
How do veterinarians diagnose lameness after TPLO surgery?
Diagnosing the cause of lameness after TPLO involves a thorough physical exam and diagnostic tests. Your veterinarian will assess your dog’s gait, pain level, and surgical site condition.
- Physical examination: Checking the operated leg for swelling, heat, pain, and range of motion helps identify inflammation or injury.
- Gait analysis: Observing how your dog walks or stands can reveal the severity and pattern of lameness.
- Radiographs (X-rays): X-rays evaluate bone healing, implant position, and detect complications like fractures or loosening.
- Joint fluid analysis: In some cases, sampling joint fluid helps detect infection or inflammation inside the knee.
These diagnostic steps guide the veterinarian in choosing the best treatment plan for your dog’s recovery.
What treatments help dogs with lameness after TPLO surgery?
Treatment depends on the cause and severity of lameness. Most dogs improve with conservative care, but some need additional interventions.
- Pain management: Using prescribed pain medications and anti-inflammatories reduces discomfort and supports healing.
- Restricted activity: Limiting running, jumping, and rough play during recovery prevents stress on the surgical site.
- Physical therapy: Controlled exercises and rehabilitation improve muscle strength and joint mobility, aiding recovery.
- Surgical revision: In cases of implant failure, infection, or meniscal injury, additional surgery may be necessary to correct problems.
Following your veterinarian’s instructions closely ensures the best outcome for your dog’s lameness after TPLO surgery.
When is lameness after TPLO surgery normal versus a concern?
Some lameness is expected after TPLO surgery, especially in the first few weeks. However, persistent or worsening limping needs evaluation.
- Normal recovery lameness: Mild limping that improves gradually over 6 to 12 weeks with rest and medication is typical.
- Warning signs: Increasing pain, swelling, heat, or inability to bear weight on the leg indicates complications.
- Delayed healing: If lameness does not improve after 3 months, further diagnostics are needed to check bone healing.
- Infection symptoms: Fever, discharge from the surgical site, or foul odor require urgent veterinary attention.
Early communication with your veterinarian helps address concerns and prevents long-term problems.
How can you support your dog’s recovery after TPLO surgery?
Supporting your dog’s recovery involves careful home care and following veterinary advice. Your role is vital to reduce lameness and promote healing.
- Follow medication schedule: Administer all prescribed painkillers and antibiotics exactly as directed to control pain and prevent infection.
- Limit exercise: Keep your dog confined to a small area and avoid stairs or slippery floors to protect the surgical site.
- Use supportive devices: Consider harnesses or slings to help your dog walk safely during early recovery stages.
- Attend follow-ups: Regular veterinary visits allow monitoring of healing progress and timely intervention if needed.
Patience and consistency in care improve your dog’s comfort and speed recovery after TPLO surgery.
What are the long-term outcomes for dogs with lameness after TPLO surgery?
Most dogs regain good function after TPLO surgery despite initial lameness. Long-term success depends on proper healing and rehabilitation.
- Improved mobility: Successful TPLO surgery stabilizes the knee, allowing dogs to return to normal activity levels over time.
- Arthritis risk: Some dogs develop arthritis in the operated joint, which may cause mild chronic lameness later.
- Rehabilitation benefits: Physical therapy improves muscle strength and joint health, reducing long-term lameness risks.
- Owner vigilance: Monitoring for new limping or pain helps catch problems early and maintain quality of life.
With proper care, dogs can enjoy active lives after recovering from lameness post-TPLO surgery.
Conclusion
Lameness after TPLO surgery in dogs is common but often temporary. It usually results from pain, swelling, or normal healing processes. Understanding the causes and treatments helps you support your dog’s recovery effectively.
If lameness persists or worsens, prompt veterinary evaluation is essential to identify complications like infection or implant issues. Following your veterinarian’s advice on medication, activity restriction, and rehabilitation maximizes your dog’s chances for a full recovery and return to normal activity.
FAQs
How long does lameness last after TPLO surgery?
Lameness usually improves gradually over 6 to 12 weeks after surgery with proper care. Some dogs may take longer depending on individual healing rates.
When should I contact my vet about lameness after TPLO?
Contact your vet if lameness worsens, your dog cannot bear weight, or you notice swelling, heat, discharge, or fever around the surgical site.
Can physical therapy help with lameness after TPLO?
Yes, physical therapy strengthens muscles and improves joint mobility, which helps reduce lameness and supports faster recovery.
Is infection common after TPLO surgery?
Infection is a possible but uncommon complication. Signs include redness, swelling, discharge, and fever, requiring prompt veterinary treatment.
Will my dog fully recover normal use of the leg?
Most dogs regain good leg function after TPLO surgery, especially with proper care and rehabilitation, though some may have mild long-term arthritis.

Patellar Tendonitis After TPLO Surgery in Dogs
Learn about patellar tendonitis after TPLO surgery in dogs, including causes, symptoms, treatment, and recovery tips for pet owners.
Patellar tendonitis more precisely called patellar desmopathy or patellar ligament desmitis in veterinary literature is a recognized complication of TPLO surgery. It is also one of the most under-discussed.
Research published in PMC shows radiographic evidence of patellar ligament thickening in 93% of dogs at 4 weeks after TPLO, though most cases are asymptomatic.
Understanding what this condition is, when it becomes a clinical problem, and how it is treated helps owners navigate one of the more commonly missed post-TPLO findings.
Quick answer: Patellar desmitis after TPLO is inflammation and thickening of the patellar ligament. Radiographic thickening occurs in 93% of TPLO dogs at 4 weeks but is usually asymptomatic. Clinically significant cases cause pain and increased lameness. Most are self-limiting; shock wave therapy accelerates resolution.
Key takeaways
- Radiographic patellar ligament thickening occurs in 93% of TPLO dogs at 4 weeks: most are asymptomatic and self-limiting
- Clinically significant patellar desmitis causes pain, swelling, and increased lameness beyond expected post-op discomfort
- TPLO changes stifle biomechanics and increases patellar tendon load: this explains why desmitis occurs more after TPLO
- Shock wave therapy (SWT) significantly reduced patellar ligament thickness at weeks 6 and 8 in a 2012 clinical trial
- Most cases are self-limiting: rest and NSAIDs resolve the majority of clinically significant cases within weeks to months
- Excessive post-operative activity is a modifiable risk factor: strict restriction in the first 8 weeks reduces desmitis risk
What is patellar desmitis after TPLO?
The patellar ligament runs from the kneecap (patella) to the tibial tuberosity — the bony bump just below the knee on the front of the tibia.
It is a critical structure for leg extension and stifle stability.
After TPLO surgery, the biomechanics of the stifle change fundamentally. The tibial plateau is rotated and held at a new angle.
This changes how forces are distributed around the knee, including the forces that pass through the patellar ligament.
The patellar ligament experiences altered tension and loading patterns after TPLO that it did not experience before surgery.
PMC research (2025 retrospective study) confirms desmopathy typically develops within 2.5 months after surgery, affecting the distal portion, and that TPLO causes more ligament thickening than other CCL repair methods.
A separate PMC study using elastosonography confirmed that patellar tendon tendinopathy can be easily detected clinically but that the exact damage evaluation is challenging without ultrasound or advanced imaging.
Why does TPLO cause patellar tendonitis?
Several mechanisms contribute:
Altered stifle biomechanics: TPLO changes the angle of the tibial plateau and the position of the tibial tuberosity relative to the femur. This alters patellar tendon geometry and tension during weight-bearing.
Surgical trauma: retraction and manipulation of soft tissues around the tibial tuberosity during the procedure causes local inflammatory changes that can involve the patellar tendon.
Intraoperative tension increase: rotating the proximal tibial segment may change the tension in the patellar tendon directly, especially during the initial healing phase.
Excessive postoperative exercise: Clinicians Brief's treatment review notes that excessive postoperative exercise is a commonly proposed contributing factor. Dogs allowed too much activity too early are more likely to develop clinically significant desmitis.
How common is patellar desmitis after TPLO?
Radiographic evidence of patellar ligament thickening at 4 weeks post-TPLO is reported in 93% of dogs in clinical studies.
The vast majority of these dogs have no clinical signs the radiographic finding does not translate into a symptomatic problem for most patients.
Clinically significant desmitis where the dog shows pain and lameness attributable to the patellar ligament specifically is less common but well-recognized by veterinary orthopedic surgeons.
Laguna Hills Animal Hospital notes that patellar tendinosis is relatively benign in most cases and improves with rest and medication.
Signs of clinically significant patellar desmitis
Unlike the asymptomatic radiographic finding, clinical patellar desmitis produces:
- Pain on direct palpation of the patellar ligament (between the kneecap and tibial tuberosity)
- Swelling or thickening directly over the ligament
- Lameness that is worse than expected for the dog's recovery stage
- Reluctance to fully extend the stifle during walking or exercise
- Stiffness after rest that improves briefly with movement
These signs typically appear in the first 6 to 10 weeks after TPLO.
Diagnosis
A veterinarian diagnoses patellar desmitis through:
Physical examination: palpation of the patellar ligament for thickening, pain response, and heat. A dog with significant desmitis will react to direct pressure on the ligament.
Radiographs: thickening of the soft tissue shadow over the patellar ligament on a lateral stifle projection. This is often identified at the routine 4 to 6 week post-TPLO radiographic recheck.
Ultrasound: provides direct visualization of the ligament, showing thickening, fiber disruption, and periligamentous edema. Ultrasound is more sensitive than radiographs and is the preferred modality for detailed assessment.
Treatment
Rest and activity restriction
The foundation of treatment for most cases. Reducing the mechanical load on the patellar ligament allows the inflammatory process to resolve.
Strict activity restriction should already be in place for post-TPLO recovery patellar desmitis is a reason to enforce it rigorously.
NSAIDs
Anti-inflammatory medication reduces pain and local inflammation. Meloxicam or carprofen at appropriate veterinary doses is the standard pharmaceutical approach for most dogs with symptomatic desmitis.
Shock wave therapy (SWT)
Clinicians Brief reviewed a trial of 30 large-breed TPLO dogs: SWT at weeks 4 and 6 significantly reduced patellar ligament thickness on radiographs at weeks 6 and 8 vs. controls.
SWT should be considered for dogs with clinically significant patellar desmitis.
Laser therapy
Low-level laser therapy (photobiomodulation) may reduce local inflammation and support tissue healing, though evidence specific to patellar desmitis after TPLO is limited compared to the SWT evidence base.

Frequently asked questions
Is patellar tendonitis after TPLO serious?
In most dogs, no. The radiographic finding is near-universal but typically asymptomatic and self-limiting.
Clinically significant desmitis causes pain and increased lameness but usually resolves with rest, NSAIDs, and sometimes shock wave therapy. It rarely causes permanent dysfunction.
How do I know if my dog has patellar tendonitis vs. normal post-TPLO soreness?
The key distinguishing feature is pain specifically on palpation of the patellar ligament the structure running from the kneecap to the bump just below the knee.
Normal post-TPLO soreness is diffuse and improves steadily. Patellar desmitis produces focal pain at this location, often with visible swelling over the ligament.
Can patellar desmitis be prevented?
Strict activity restriction in the first 8 weeks post-TPLO is the most effective preventive measure, since excessive early activity is a recognized contributing factor.
It cannot always be prevented altered biomechanics from the surgery itself play a role regardless of activity level but minimizing mechanical load during the healing phase reduces severity.
Does patellar tendonitis require a second surgery?
Almost never. The vast majority of cases resolve with conservative management. Shock wave therapy is effective in cases that need more active treatment.
Surgical intervention for patellar desmitis after TPLO is extremely rare.
Will this affect my dog's long-term outcome after TPLO?
For most dogs, no. Clinically significant patellar desmitis is typically a temporary complication that resolves during the recovery period.
Long-term stifle function in dogs that develop and recover from patellar desmitis is generally comparable to dogs that do not develop the condition.

How to Confine Your Dog Post-TPLO Surgery
Keep your dog safe after TPLO surgery with smart confinement tips. Learn crate setup, barriers, and daily care for smooth healing
Confinement after TPLO surgery is not optional. It is the primary structural safeguard preventing the plate from failing before the osteotomy heals.
A dog that is allowed to run, jump, or spin in the first 8 weeks risks plate displacement -- a complication that requires revision surgery and extends recovery significantly.
Effective confinement is a practical skill that owners can prepare for before surgery.
Quick answer: Confine in a crate large enough to stand, turn, and lie but not to pace. An exercise pen works for crate-resistant dogs. A baby-gated small room is a third option. Non-slip flooring is essential. Outdoor access requires a leash. Strict confinement continues for 6 to 8 weeks.
Key takeaways
- The crate is the gold standard confinement tool: limits jumping, spinning, and running that risk plate displacement; large enough to stand and turn but not to pace
- Non-slip flooring is required in all confinement spaces: slipping generates uncontrolled leg movements that stress the plate
- Leash on the dog at all times outside the crate: every unsupervised second without a leash risks slipping or running; a house leash gives immediate control
- Exercise pens (X-pens) are a practical alternative for crate-resistant dogs: more space than a crate while still preventing free access to the rest of the house
- The confinement protocol changes weekly: strict crate-only in weeks 1 to 2, then gradual expansion as bone healing is confirmed on radiographs
- Clean bedding weekly: dirty bedding harbors S. pseudintermedius; the incision is in close contact with bedding throughout recovery
Why confinement matters
The TPLO plate holds the rotated tibial plateau in position while new bone grows across the osteotomy. The plate is strong but not indestructible.
Bone is not fully consolidated across the osteotomy for 8 to 12 weeks.
During this healing period, a dog that runs, jumps onto a sofa, slips on hardwood flooring, or spins to chase another pet can apply forces to the plate that exceed its tolerance.
Plate bending, screw loosening, or osteotomy displacement are the results. Each requires revision surgery.
SustainableVet.org confirms: dogs typically need 6 to 8 weeks of restricted activity before returning to light exercise; strict confinement ensures the bone plate stabilizes and heals properly.
Option 1: the crate
Why crates work best
A crate completely controls the dog's environment. The dog cannot run to the door, jump on the sofa, or spin in excitement. Every movement is small, controlled, and low-impact.
SustainableVet.org confirms: a crate is one of the safest ways to confine a dog after TPLO surgery; crates help prevent jumping, running, or sudden twisting that can damage the healing leg.
Crate selection
Size: the crate must be large enough for the dog to stand fully, turn around, and lie in any direction comfortably. It should NOT be large enough for the dog to trot or run inside it -- an oversized crate allows the dog to generate enough speed within the crate to create impact when stopping.
Flooring: avoid wire-bottomed crates. The dog's leg can slip through wire flooring. Use solid-floored crates or add a mat over wire flooring.
Bedding: comfortable, non-slip bedding. Memory foam dog mats are excellent for TPLO dogs -- they cushion pressure points during long rest periods.
Location: place the crate in the main family living area, not in an isolated room. Isolation increases separation anxiety and whining. A dog that can see and hear the family is calmer and more able to rest.
TPLO Info confirms: dogs do not like dirty bedding, so wash crate items at least once a week.
Transitioning a crate-naive dog
If the dog has never been crated, introduce the crate before surgery:
- Place meals in the crate with the door open for several days before surgery
- Gradually extend time inside with the door closed, building from 10 minutes to 1 hour
- Never force the dog in or use the crate for punishment
A dog that enters the crate willingly before surgery recovers with significantly less confinement-related distress.
Option 2: the exercise pen (X-pen)
An X-pen is a freestanding modular fence creating a confined area larger than a crate. It can be configured in different shapes and sizes.
TPLO Info confirms: X-pens give enough room to move while keeping the dog in one place. Larger dogs may attempt to jump over the fence and require monitoring.
Advantages: more space than a crate, reducing frustration in dogs that do not tolerate crates; can be set up in any room.
Disadvantages: requires monitoring for jumping attempts; the dog can build more momentum in a larger space; not suitable for very large or athletic dogs who can clear the fence.
Height: use a 48-inch or taller X-pen for medium and large dogs; even a non-athletic dog may clear a 36-inch pen if motivated.
Flooring inside the X-pen: place yoga mats or a rubber-backed rug inside to cover hard flooring.
When to use an X-pen: recommended after the initial 2 weeks of strictest confinement, when the dog has established initial healing and the wound is closed. Not ideal for weeks 1 to 2.
Option 3: a baby-gated small room
A bathroom, laundry room, or small bedroom can serve as a recovery room when gated with a baby gate.
Dog Knee Injury confirms: prepare your home for post-surgery by setting up a recovery space with a comfortable dog bed, non-slip flooring, and a baby gate to create a barrier.
Requirements:
- Non-slip flooring throughout (add yoga mats or rugs)
- No furniture the dog can jump onto or off
- Accessible water and food bowls at floor level
- The gate must prevent the dog exiting unsupervised
Advantages: familiar environment, easy human access, more comfortable than a crate for larger dogs.
Disadvantages: more space means more opportunity for movement; the dog can circle and pace in a room, which a crate prevents; requires strict monitoring.
Outdoor access: leash only, no exceptions
Every outdoor bathroom trip requires a leash. No exceptions.
SustainableVet.org confirms: always use a leash when outside, even for bathroom breaks; open-door access to the yard allows a dog to run, chase, or slip before the owner can intervene.
Leash length: short -- no retractable leashes. The owner must be able to prevent sudden running immediately. A 4 to 6 foot leash is appropriate.
Bathroom trip duration: 5 minutes maximum in weeks 1 to 2. Gradual increase per the vet's protocol.
Wet weather: rain and wet grass introduce bacteria to the incision area and also create slipping hazard. Time trips to avoid heavy rain where possible; carry a dry towel.
Week-by-week confinement protocol
Weeks 0 to 2 (strictest):
- Crate at all times except supervised bathroom leash walks
- 5-minute walks, 3 to 5 times daily
- E-collar on at all times
- No access to any area without owner supervision
Weeks 2 to 6 (moderate):
- Crate or X-pen when unsupervised
- Supervised time in the confinement room with owner present
- Leash walks increasing gradually per vet's direction
- E-collar until incision fully confirmed healed at 2-week recheck
Weeks 6 to 12 (graduated relaxation):
- Confinement continues but may expand to a room-sized area under supervision
- Activity increases based on radiographic findings at 6-week recheck
- Off-leash access to the house (not yard) under close supervision for some dogs, vet-directed
After 12 weeks (post-clearance):
- Full activity restriction lifted after radiographic bone healing confirmation
- Progressive return to normal environment and activity
- Still avoid high-impact play until full muscle recovery at 4 to 6 months

Frequently asked questions
My dog has never been in a crate. Can I start at surgery?
Yes, but start before surgery if possible -- even a few days of crate introduction before surgery significantly reduces post-operative confinement distress.
If you cannot prepare beforehand, introduce the crate gently in the first day or two at home, using meals and treats to create positive associations.
How do I know if the crate is the right size?
The dog should be able to stand with their head up, turn in a full circle, and lie in multiple positions without being cramped.
They should NOT be able to trot or run within the crate space. If in doubt, err toward smaller.
My dog cries in the crate for hours. Is the confinement causing psychological harm?
Extended, severe crate distress may indicate inadequate pain management (the dog is in pain, not just frustrated) or genuine severe separation anxiety. Contact your vet.
Trazodone and gabapentin can significantly reduce confinement distress. Do not abandon confinement -- the physical risk of uncontrolled activity is greater than the psychological discomfort of confinement.
Can my dog sleep in my bed during recovery?
No. Jumping off the bed -- even a single time -- can displace the plate.
The dog must sleep in the crate or on a floor-level dog bed in the recovery area throughout the restriction period.
Can I let my dog outside in a fenced yard for bathroom breaks without a leash?
No. Dogs routinely run, spin, and perform sudden movements in yards even when told to go to the bathroom.
A single run to chase a squirrel or greet someone at the fence is enough to cause plate failure before the osteotomy heals. Leash only, every time.
