TPLO Operation in Dogs​

Tibial Plateau Leveling Osteotomy (TPLO) is a specialized orthopedic surgery for dogs with a torn cranial cruciate ligament (CCL). This article covers everything you need to know about TPLO surgery, from what it involves and why it’s needed, to recovery timelines, costs, and alternatives.

What Is TPLO Surgery in Dogs?

TPLO surgery corrects the instability caused by a torn CCL, similar to a torn ACL in humans. The procedure reshapes the tibia bone to reduce the forward sliding motion of the femur over the tibia, stabilizing the knee joint without needing the ligament.

Why Should Dogs Have TPLO Surgery?

• Severe CCL Tears: Dogs with complete CCL ruptures cannot stabilize the knee on their own.
• Active Breeds: Large, active dogs benefit most because TPLO allows for better joint movement and stability.
• Chronic Lameness: If left untreated, a torn CCL can lead to arthritis, decreased mobility, and chronic pain.

TPLO Recovery Timeline

Recovery from TPLO surgery takes several months and involves strict rest, rehabilitation, and follow-up appointments.

Week-by-Week Recovery Plan:

Week 1-2:

• Rest and confinement with minimal walking.
• Use a dog crate or small space to restrict movement.
• Pain management with prescribed medications.

Week 3-6:

• Short, controlled leash walks (5-10 minutes).
• Begin passive range-of-motion exercises if recommended by the vet.

Week 7-10:

• Gradual increase in walk length and low-impact exercises.
• Consider rehabilitation therapy such as swimming or underwater treadmill sessions.

Week 11-16:

• Longer walks and supervised play.
• X-rays will confirm if the bone has fully healed.

Full Recovery:

• Most dogs recover within 4-6 months, regaining normal activity levels.

TPLO Failure Symptoms

While TPLO has a high success rate (over 90%), failures can occur due to various reasons:

Signs of TPLO Failure:

• Persistent limping or lameness
• Swelling around the surgery site
• Pain upon touching the knee
• Decreased activity or reluctance to move

Causes of TPLO Failure:

• Implant loosening or breakage
• Bone infection (osteomyelitis)
• Incomplete healing of the bone
• Improper postoperative care

Risk Factors:

• Overweight dogs
• Insufficient post-surgery rest
• Surgical complications

Before and After TPLO Surgery for Dogs

Differences Between Before and After TPLO Surgery for Dogs

TPLO surgery for dogs involves significant changes in their physical condition, activity levels, and overall well-being. Here's a detailed comparison of the before and after stages of TPLO surgery:

1. Mobility and Activity Level

Before TPLO Surgery:

• Limited Mobility: Dogs may limp, avoid putting weight on the affected leg, or struggle with basic movements like walking, running, or jumping.
• Decreased Activity: Dogs may be less active due to pain, showing signs of fatigue or reluctance to play.

After TPLO Surgery:

• Improved Mobility: With proper healing, most dogs regain near-normal or even better mobility compared to before surgery.
• Increased Activity: After full recovery (4-6 months), dogs can return to running, jumping, and playing.

2. Pain and Discomfort

Before TPLO Surgery:

• Chronic Pain: Dogs often experience significant knee pain, swelling, and discomfort.
• Arthritis Risk: Ongoing CCL injuries can cause severe arthritis if left untreated.

After TPLO Surgery:

• Reduced Pain: Post-surgical pain is managed with medication and typically decreases within weeks.
• Lower Arthritis Risk: Proper recovery helps slow or prevent arthritis development.

3. Appearance of the Affected Leg

Before TPLO Surgery:

• Swollen Knee: The injured leg often appears swollen due to inflammation.
• Muscle Atrophy: Due to lack of use, the leg muscles may weaken and appear smaller.

After TPLO Surgery:

• Surgical Scar: A visible scar will remain along the knee but fades over time.
• Rebuilt Muscles: With physical therapy and proper care, muscle mass usually returns.

4. Dog’s Behavior and Mood

Before TPLO Surgery:

• Irritability: Pain and limited mobility can cause dogs to be irritable, restless, or withdrawn.
• Low Energy: They may become less interested in walks or playtime.

After TPLO Surgery:

• Happier Mood: Dogs often show increased enthusiasm and playfulness after recovery.
• Higher Energy Levels: They return to a more energetic and active lifestyle.

5. Medical and Care Needs

Before TPLO Surgery:

• Frequent Vet Visits: Ongoing vet visits for diagnosis, pain management, and monitoring may be necessary.
• Medication Dependency: Anti-inflammatory medications and painkillers may be used regularly.

After TPLO Surgery:

• Follow-Up Appointments: Regular follow-ups are needed during the recovery phase.
• Reduced Medications: Most dogs no longer need long-term medication once fully healed.

6. Quality of Life

Before TPLO Surgery:

• Reduced Quality of Life: Dogs may struggle with limited mobility, ongoing pain, and reduced playtime.

After TPLO Surgery:

• Enhanced Quality of Life: Once fully healed, dogs can live an active, pain-free life with minimal mobility restrictions.

What Should Keep In Mind Before and After Surgery

Before Surgery:

• Ensure your dog is in good health and up-to-date on vaccinations.
• Perform blood work and X-rays to confirm CCL tear.
• Follow preoperative fasting instructions.

After Surgery:

• Monitor the surgical site for redness or discharge.
• Use an e-collar to prevent licking or biting the incision.
• Strict rest and follow-up visits for X-rays and evaluations.

TPLO Surgery Cost

The cost of TPLO surgery ranges from $3,000 to $7,000, depending on factors such as:

• Veterinary surgeon’s expertise
• Location and clinic reputation
• Pre-surgical exams, X-rays, and follow-up care

How Long Does TPLO Surgery Take?

The surgery itself takes approximately 1.5 to 3 hours, including anesthesia, preparation, and the procedure. Additional time is needed for post-op monitoring before discharge.

Is TPLO Surgery Worth It?

Pros:

• High success rate
• Restores mobility and active lifestyle
• Reduces arthritis development

Cons:

• Expensive and requires extensive recovery time
• Risk of surgical complications

Most pet owners find TPLO surgery worth it, especially for young, active dogs.

What Causes CCL Tears in Dogs?

Several factors contribute to CCL injuries in dogs:

• Genetics: Certain breeds like Labrador Retrievers and Rottweilers are predisposed.
• Obesity: Extra weight strains the knee joints.
• Aging: Older dogs face wear and tear.
• Activity Level: Sudden stops, jumps, or turns can cause tears.

Alternatives to TPLO Surgery for Dogs

If TPLO surgery isn’t suitable, other options include:

1. TTA (Tibial Tuberosity Advancement):
   Similar to TPLO, this surgery stabilizes the knee by altering tibial mechanics.
2. Lateral Suture Technique:
   Best for smaller dogs, a synthetic ligament replaces the torn CCL.
3. CBLO (Cora-Based Leveling Osteotomy):
   A newer technique adjusting the tibia bone angle.
4. Conservative Management:
   Includes weight loss, anti-inflammatory medications, and physical therapy (effective for minor injuries).

How Long Should Dogs Rest After CCL Surgery?

Dogs should rest for 8-12 weeks, with restricted activity and gradually increasing exercise as approved by the vet.

What Happens If I Don’t Get TPLO Surgery for My Dog?

Without surgery, dogs may face:

• Chronic Pain: Due to joint instability and arthritis development.
• Lameness: Permanent or worsening over time.
• Reduced Quality of Life: Limited mobility, weight gain, and increased risk of other injuries.

How Painful Is TPLO Surgery for Dogs?

While the surgery is invasive, pain management protocols ensure comfort:

• Post-Surgical Pain Relief: Vets prescribe anti-inflammatory medications, painkillers, and sometimes joint supplements.
• Recovery Discomfort: Dogs may experience temporary stiffness, swelling, and sensitivity but should improve within weeks.
