Luxating patella is a condition where the patella, or kneecap, moves out of its normal location. It is commonly seen in small and miniature dogs, but can also occur in larger breeds. The condition can be congenital or caused by trauma.

Causes

The exact cause of luxating patella is unknown, but it is believed to be genetic. The condition is more common in certain breeds, including the Yorkshire Terrier, Pomeranian, Chihuahua, and French Bulldog. Trauma can also cause the patella to luxate.

Symptoms

Symptoms of luxating patella can vary depending on the severity of the condition. Dogs with a mild case may not show any symptoms, while those with a severe case may have difficulty walking and experience pain. Other symptoms can include limping, abnormal gait, and reluctance to put weight on the affected leg.

Diagnosis

Diagnosis of luxating patella is usually made through a physical examination and X-rays. The vet may also recommend a CT scan or MRI for a more detailed view of the knee joint.

Treatment

Treatment for luxating patella depends on the severity of the condition. Mild cases may not require treatment, while severe cases may require surgery. Physical therapy and weight management can also help manage the condition.

Prevention

Prevention of luxating patella involves breeding dogs with healthy knees. Regular exercise and maintaining a healthy weight can also help prevent the condition.
