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.
Luxating patella (or trick knee, subluxation of patella, floating patella, or floating kneecap) is a condition in which the patella, or kneecap, dislocates or moves out of its normal location.Patellar luxation is a common condition in dogs, particularly small and miniature breeds.ften a dog owner might be told that his or her pet has  loose knee , but this is not a medical term, and it is not correct to use it interchangeably with Luxating Patella. Luxating Patella cannot be present without the knee being loose, but a loose knee is not necessarily slipping out of the joint.
