Knees hold the rhythm of movement.
Patellar Luxation
Patellar Luxation is a condition where the kneecap (patella) slips out of its normal groove in the femur, leading to intermittent lameness, pain, or abnormal gait. It can be congenital or develop due to trauma or structural abnormalities.
Small and toy breeds are most commonly affected, though large breeds can also suffer from this condition. The severity ranges from mild luxation with occasional skipping to permanent displacement requiring surgical intervention.
Patellar luxation may look like a “skipping step” – early recognition helps prevent long-term joint damage and arthritis.
Core signs of Patellar Luxation include:
- Skipping or hopping gait in one hind leg
- Sudden lameness that resolves quickly
- Pain or stiffness after exercise
- Progressive difficulty in mobility
With proper diagnosis and treatment, most dogs with patellar luxation can live active and comfortable lives.
Patellar Luxation – FAQ
Small breeds such as Pomeranians, Chihuahuas, Yorkies, and Toy Poodles are most often affected, though large breeds can also develop it.
It is classified into four grades, from Grade I (mild, occasional slipping) to Grade IV (permanent displacement with severe mobility issues).
No. Mild cases may be managed with weight control, physiotherapy, and joint supplements. Severe or painful cases usually require surgery.
Yes. Repeated luxation damages cartilage, leading to arthritis and chronic pain over time.
It is often genetic, so prevention is difficult. Responsible breeding, healthy weight maintenance, and avoiding injuries lower the risk.
