Does your dog ever skip a step or suddenly hold up a back leg — then act like nothing happened? That could be a sign of patellar luxation — one of the most common orthopedic conditions in dogs, and one worth understanding.
What is it?
The patella (kneecap) sits within a groove at the end of the thighbone. Patellar luxation occurs when the kneecap slides or pops out of that groove when the knee flexes. It can affect one or both knees. (Image source: Holt 2017)
Who's at risk?
It's more common in small breeds like Toy Poodles, Yorkshire Terriers, Chihuahuas, and Pomeranians — but it can occur in large breeds too. Cats can also be affected. Genetics play a significant role, though it can also occur following trauma.
What does it look like?
The most recognizable sign is an intermittent "skipping" lameness — a sudden three-legged gait that quickly resolves after a few steps or a kick of the leg. Mild cases can go unnoticed for a long time.
Why does it matter?
As the condition progresses, the patella dislocates more easily and more frequently, wearing down cartilage and leading to arthritis. It can also increase the risk of cruciate ligament injury down the road.
What are the options?
Mild cases can often be managed conservatively with weight management, joint supplements, and pain medications. More advanced cases may benefit from surgical correction — which, when performed early, typically leads to excellent outcomes.
