TPLO Surgery for CCL Injuries in Dogs: A 2025 Vet Guide by Dr Duncan Houston 🦴🐾
By Dr Duncan Houston, BVSc | July 2025
🧠 What Is TPLO Surgery?
TPLO (Tibial Plateau Leveling Osteotomy) is a surgical technique used to stabilize a dog’s knee joint after a rupture of the cranial cruciate ligament (CCL). This procedure changes the angle of the tibial plateau (top of the shin bone), removing the need for the CCL to stabilize the joint. 🦿
🔍 Understanding CCL Disease
Unlike humans, where ACL tears often result from trauma, most canine CCL ruptures develop gradually due to ligament degeneration. When the CCL fails:
- 🐶 Dogs may suddenly limp
- 🦴 The tibia slides abnormally forward during movement
- ⚠️ Meniscal cartilage may tear, worsening pain and joint damage
💡 When Is TPLO Recommended?
TPLO is the gold standard for:
- 🐕 Large or active dogs of any size
- 🏃♂️ Dogs with complete CCL ruptures
- 🔁 Recurring or bilateral CCL injuries
About 85% of dogs over 20 lbs regain excellent limb function with TPLO, while untreated CCL injuries often lead to chronic pain and arthritis.
🛠️ How TPLO Surgery Works
- 📸 Specialized X-rays are taken to measure angles
- 🔍 The joint is inspected via arthroscopy or small incision
- 🦴 The top of the tibia is cut, rotated, and re-aligned
- 🔩 A metal plate and screws stabilize the bone segments
- 💧 The joint is flushed and the incision closed
Post-op X-rays confirm proper alignment. Your dog may go home the same day or stay 1–2 nights for observation and pain control.
📆 Recovery Timeline
- Day 1–14: Strict rest, pain meds, incision care
- Weeks 2–8: Leash walks only, no stairs or jumping
- Week 8: Follow-up X-rays to assess bone healing
- Weeks 8–12: Gradual return to normal activity, guided by rehab
Healing time is typically 8–12 weeks, depending on age, health, and compliance with post-op care. ⏱️
💊 Post-Op Management
- 💉 Pain relievers (NSAIDs or tramadol)
- 🧊 Cold therapy in the first few days
- 🧘 Gentle stretching and passive range of motion
- 💪 Hydrotherapy or treadmill rehab (optional but highly beneficial)
⚠️ Potential TPLO Complications
Minor:
- 🩹 Mild infection or swelling
- 🐾 Temporary lameness or soreness
- 🔥 Tendonitis near the incision
Major:
- 🔩 Plate or screw failure
- 🦴 Fracture of the tibia
- 🧫 Deep surgical site infection
- 🚨 Failure of bone to heal (non-union)
Choosing an experienced surgeon and following strict post-op instructions greatly reduce risks. 🛡️
🧬 Meniscal Tears and TPLO
Meniscal damage often accompanies CCL injuries. During TPLO, the meniscus is carefully evaluated and trimmed or removed if torn. Eliminating joint instability with TPLO also reduces the risk of post-op meniscal injury.
📋 TPLO Surgery Snapshot
| Aspect | Details |
|---|---|
| Ideal For | Large, athletic, or severely lame dogs |
| Surgical Goal | Eliminate abnormal tibial thrust |
| Implants | Plate + screws |
| Recovery Time | 8–12 weeks |
| Follow-up | X-rays at 8 weeks |
| Success Rate | 85–90% excellent long-term function |
❓ TPLO vs. Other Options
Compared to extracapsular repair or TTA (Tibial Tuberosity Advancement), TPLO is more invasive and expensive but generally provides superior results in large or highly active dogs. Discuss all options with your vet to find the best fit for your pet. 🧠
