Cruciate Ligament Tears

Cruciate ligament tears (similar to ACL tears in humans) are common knee injuries in dogs, especially in larger breeds. The cranial cruciate ligament (CCL) stabilises the knee joint, and when torn, causes instability, pain, and eventually arthritis if untreated. These injuries can occur suddenly from trauma or develop gradually from degenerative changes.

Symptoms:

• Sudden lameness in a hind leg
• "Toe-touching" lameness (limb used but not bearing full weight)
• Difficulty rising from a sitting position
• Reluctance to jump or climb stairs
• Sitting abnormally with the affected leg extended
• Muscle atrophy (wasting) in the affected leg over time
• Clicking sound when walking

Action Steps:

1. Contact your veterinarian for an examination.
2. Rest your pet and prevent jumping, running, or stairs.
3. Apply ice wrapped in a towel for 10-15 minutes several times daily for acute injuries.
4. Discuss surgical and non-surgical treatment options with your vet.
