Patellar Luxation Behavior in Dogs257

Patellar luxation is a common orthopedic condition in dogs, characterized by the dislocation of the kneecap, or patella, from its normal position in the groove on the end of the femur. This dislocation can cause pain, lameness, and difficulty walking. While patellar luxation can affect dogs of all ages, breeds, and sizes, it is most commonly seen in small breeds, such as the Pomeranian, Yorkshire Terrier, and Chihuahua.

Symptoms of Patellar Luxation

The symptoms of patellar luxation can vary depending on the severity of the condition. In mild cases, the patella may only dislocate occasionally and the dog may show no signs of discomfort. In more severe cases, the patella may be permanently dislocated and the dog may experience significant pain and lameness. Common symptoms of patellar luxation include:
Limping or lameness
Hopping or skipping on the affected leg
Holding the affected leg up
Knuckling over on the affected leg
Pain when the knee is extended or flexed
Swelling and stiffness in the knee joint
Grating or popping sound when the knee is moved

Causes of Patellar Luxation

Patellar luxation is caused by a combination of factors, including genetics, anatomy, and environment. Some dogs are born with a shallow groove on the end of the femur, which makes the patella more likely to dislocate. Other dogs may have a condition called medial patellar luxation syndrome, which is caused by a misalignment of the bones in the knee. Environmental factors, such as obesity and trauma, can also contribute to patellar luxation.

Diagnosis of Patellar Luxation

Patellar luxation is diagnosed based on a physical examination and a history of the dog's symptoms. The veterinarian will examine the dog's knee and look for signs of dislocation, pain, and swelling. The veterinarian may also perform a drawer test to check for instability in the knee joint. In some cases, X-rays may be taken to confirm the diagnosis and rule out other conditions.

Treatment of Patellar Luxation

The treatment for patellar luxation depends on the severity of the condition. In mild cases, the veterinarian may recommend conservative treatment, such as weight loss, exercise, and physical therapy. In more severe cases, surgery may be necessary to repair the damaged tissues and stabilize the knee joint. The type of surgery performed will depend on the individual dog's needs.

Prognosis for Dogs with Patellar Luxation

The prognosis for dogs with patellar luxation is generally good. With proper treatment, most dogs can recover fully and live a normal, active life. However, some dogs may experience chronic pain or lameness, even after surgery. The prognosis for dogs with medial patellar luxation syndrome is typically poorer than for dogs with other types of patellar luxation.

Conclusion

Patellar luxation is a common orthopedic condition in dogs that can cause pain, lameness, and difficulty walking. The condition is caused by a combination of factors, including genetics, anatomy, and environment. The diagnosis of patellar luxation is based on a physical examination and a history of the dog's symptoms. The treatment for patellar luxation depends on the severity of the condition and may include conservative treatment, surgery, or a combination of both. The prognosis for dogs with patellar luxation is generally good, but some dogs may experience chronic pain or lameness, even after surgery.
