Ask a Vet: Does My Dog with Patellar Luxation Need Surgery?

Patellar luxation (dislocated kneecap) is a common condition, especially in small breed dogs. Dr. Loon from Amber Vet tells us when surgery may be needed.

Q. My dog has luxating patella. How do I tell when she needs surgery?

Dr. Brian Loon: Patellar luxation (dislocated or floating kneecap) is a common condition, especially in small breed dogs. It is a result of anatomic bone deformities.

A decision on whether to perform surgery for patellar luxation depends on the following factors:

  • Clinical signs

  • Age

  • Severity of luxation

  • Presence of any other bone deformities

Surgery may generally be recommended for dogs with:

  • a chronic lameness of more than two to three weeks

  • multiple episodes of lameness, or

  • severe luxation (Grade 3-4 out of 4)

Your trusted vet should assess your dog’s knee and bones and discuss with you whether surgery is a good option for your dog.

You may also consult a veterinary orthopaedic surgeon if you are contemplating surgery.
