What is Patellar Luxation?

Patellar luxation (dislocation) occurs when the knee cap (patella) rides outside the femoral groove during knee flexion.

The patella normally rides within a groove in the femur, but in patellar luxation, it shifts out of place.

It can be medial (inner aspect) or lateral (outer aspect) depending on the direction of displacement.

Indications:

• • Commonly diagnosed in dogs, especially small breeds like Boston terriers, Chihuahuas, and miniature poodles.
  • Large breed dogs are also affected, including Chinese Shar Pei, Flat-Coated Retrievers, Akitas, and Great Pyrenees.
  • Bilateral involvement (both knees) occurs in half of all cases, leading to discomfort and loss of function.

Surgical Treatment:

• • Recommended for grade 2, 3, or 4 luxation with a history of lameness.
  • Strategies include:
    • Deepening the femoral groove.
    • Tibial tuberosity movement.
    • Tissue manipulation around the kneecap.

Benefits:

• • Pain relief.
  • Improved joint function.
  • Favorable prognosis, especially in small dogs.
