Luxating patella - a knee cap problem in dogs. The patella, commonly referred to as the knee cap is usually located in the centre of the knee joint. A luxating patella is a knee cap that moves out of its normal location, as indicated by the term luxating which means out of place or dislocated.
In small dogs, a luxating patella may lead to a torn ACL. These symptoms include sudden pain in your dog as his knee becomes popped out of joint. This is often short-lived as your dog will pop the knee back in place and often appear fine after a few hours. Consult your veterinarian when this happens.
