Patella luxation surgery is a corrective procedure for pets experiencing kneecap dislocation, a condition that can cause pain, lameness, and long-term joint damage.

Common in small-breed dogs but recognized with increasing frequency in larger breed dogs and occasionally seen in cats, patella luxation occurs when the kneecap (patella) shifts out of its normal position, often due to a combination of genetic factors / structural abnormalities.

Whilst many patients can actually live a normal functional life with patella luxation there are some cases that require surgical correction. The procedure stabilizes the kneecap reducing discomfort and restoring mobility.

Early intervention can prevent further complications, helping pets lead active, pain-free lives.

What is Medial/Lateral Patella Luxation?

The patella is a small bone that sits within the patellar ligament and moves along a groove in the femur during motion. Patella luxation occurs when the kneecap shifts out of this groove. The condition can be classified based on the direction of dislocation:

  • Medial Luxation: The kneecap dislocates toward the inner side of the leg. This is more common in small-breed dogs and some cats.
  • Lateral Luxation: The kneecap dislocates toward the outer side of the leg. This is more common in large-breed dogs.

Symptoms of Patella Luxation in Dogs & Cats

The severity of symptoms varies depending on the grade of patella luxation, which ranges from mild (Grade I) to severe (Grade IV):

  • Grade I: The kneecap occasionally dislocates but returns to its normal position on its own. Mild lameness may occur.
  • Grade II: The kneecap dislocates more frequently and may require manual adjustment to return to its position. Lameness is more noticeable.
  • Grade III: The kneecap remains dislocated most of the time but can be manually repositioned. Pets may show significant lameness and discomfort.
  • Grade IV: The kneecap is permanently dislocated and cannot be repositioned. Severe lameness and abnormal gait are common.

Common signs include:

  • Skipping or hopping during movement
  • Reluctance to bear weight on the affected leg
  • Lameness that worsens after activity
  • Joint stiffness or swelling

FAQs

What is the difference between medial and lateral patellar luxation?

  • Medial Luxation: The kneecap dislocates toward the inner side of the leg. This is more common in small-breed dogs and some cats.
  • Lateral Luxation: The kneecap dislocates toward the outer side of the leg. This is more common in large-breed dogs and is generally associated with more severe cases.

Any or all of them. The degree of patella luxation does not necessarily correspond with lameness.

Absolutely. With successful surgery pets can return to normal function lifelong.

Many animals can lead a normal functional life with varying degrees of patella luxation and so that is the reason surgery is generally recommended when the pat has clinical symptoms.

It is not a progressive condition so almost all cases the grade they are born with is the grade they remain through life.
