Patella Luxation in Dogs and Cats

(or trick knee, subluxation of patella, floating patella, or floating kneecap)

General Information

A luxating patella is frequent problem in dogs – especially in small and toy breeds. Large breed dogs can also be affected. Mostly a patellar luxation occurs medial. It can result from a blunt trauma but in most cases it is a congenital defect. In these cases it frequently occurs in both legs.

A veterinarian can do a manual diagnosis of the knee and see if the patella slides off the joint. A patella luxation can occur in four different grades. In grade 1 the patella can be moved or luxated manually but it takes its natural position again after the patella is released. In grade 4 the patella luxated permanently with up to 90° of rotation of the proximal tibial plateau.
