WHAT IS A PATELLAR DISLOCATION IN DOGS?
Dislocation of the kneecap (patella dislocation) is a common cause of lameness in dogs. Especially small breeds of dogs (especially dwarf breeds, for example Chihuahua, Jack Russell Terrier) as well as growing and older dogs are susceptible to patellar dislocation.
The kneecap (patella) is a flat, disc-shaped bone located in front of the knee joint. In patella dislocation, the dog’s patella jumps out of its glide channel in the thigh bone. As a result, the dog can no longer load the leg properly or only under pain.
WHAT ARE THE CAUSES OF PATELLAR DISLOCATION IN DOGS?
Possible causes of patellar dislocation in dogs are a congenital gliding groove that is too flat and deviations in the bone axis between the thigh and lower leg.
Joint diseases such as osteoarthritis (joint wear) in older dogs can also promote patellar dislocation.
