What is Kneecap Dislocation in Cats
Patella luxation is a condition in which the kneecap (patella) becomes detached from its normal position. The patella is a bone on the front surface of the hind legs that provides stability to the knee joint. Patella luxation is a common condition, especially in small and short cat breeds, and occurs in the hind legs because the front legs do not have a kneecap.
What Causes Kneecap Dislocation in Cats?
Most cases of patella luxation are caused by a genetic predisposition. It can occur as a congenital anomaly or develop in the first few months of a cat's life. In rare cases, trauma such as ligament and tendon injuries can also cause patella luxation. The following breeds are more likely to have a luxated patella
- Abyssinian
- Burmese
- Devon Rex
What are the Symptoms of Kneecap Dislocation in Cats?
Symptoms of patella luxation are usually as follows:
- Limping
- Leap
- Jumping on one leg
Cats usually feel no pain and continue to move normally once the kneecap returns to its normal position.
Degrees of Kneecap Dislocation in Cats
Patella luxation is usually categorized into four degrees. Each grade indicates the severity of the dislocation of the patella:
First degree: This is the mildest grade. The patella may dislocate and return to its original position spontaneously. Without intervention, this may lead to a more severe luxation in the future.
Second degree: The patella may dislocate spontaneously. Even if the leg moves, posture and movement disorders may indicate this condition. With manual intervention by the veterinarian, the knee usually returns to its original position.
Third degree: This is when the kneecap does not fit back into place spontaneously and is often dislocated. Manual intervention by veterinarians can restore the knee to its original position.
Fourth Degree: The most severe condition in which the patella is constantly dislocated and cannot be replaced manually. It usually requires surgical intervention.
Diagnosis and Treatment of Knee Cap Dislocation in Cats
Patella luxation is usually diagnosed by physical examination and X-rays. Treatment depends on the severity of the condition. Mild cases are usually managed with pain control and physiotherapy, while severe cases usually require surgery. After surgical procedures, most cats return to a normal level of activity.
How long does it take to heal a dislocated kneecap in cats?
The duration of treatment for patella luxation depends on the severity of the condition and the method of treatment. In severe cases requiring surgical intervention, recovery can take 6-8 weeks. Mild cases can recover within a few weeks with appropriate physiotherapy and weight management.
