Dog cruciate ligament injury — surgery or rest? Symptoms and treatment options

📍 Veterinary Hospital Sacrum, Vantaa — Orthopedic Surgery and TPLO

Anterior cruciate ligament rupture is one of the most common orthopedic injuries in dogs. Unlike humans, in dogs the cruciate ligament rarely breaks due to mere accident; the underlying condition is often degeneration of the ligament, which eventually leads to a break as a result of even a slight movement.

Once the diagnosis is confirmed, the owner is faced with a big question: surgery or rest?

Symptoms: How do I recognize a cruciate ligament injury?

A typical symptom is sudden lameness of the hind leg.

• The dog is careful not to put weight on the leg.
• When sitting, the dog may extend the sore leg to the side (“sit test”).
• A so-called medial buttress swelling (hardening) can form on the inside of the knee.

Treatment Options: Surgery vs. Conservative Therapy

The choice depends on the size, age and activity level of the dog.

1. Surgical treatment (TPLO or TTA)

For large and active dogs (more than 10 kg), surgery is almost always the most recommended option.

• TPLO surgery: Changes the angle of the tibia so that the knee does not need an anterior cruciate ligament to be stable.
• Pros: Faster recovery, less development of osteoarthritis and a better return to active life.

2. Conservative treatment (Rest and Analgesic)

For dogs under 10 pounds, rest, weight management, and physical therapy can sometimes be tried.

• Risks: The knee is often left unstable, leading to rapidly progressive osteoarthritis and chronic pain. In larger dogs, the results are rarely good.

Recovering

After surgery, a rehabilitation period follows, which includes limited physical activity and physiotherapy. Most patients return to normal, active life.
