I Think My Dog Has A Luxating Patella. What Should I Do? (Including All The Grades)

A luxating patella (sometimes called a floating kneecap) is a common orthopaedic condition in dogs. Although it can occur as a result of a traumatic injury, it is mostly commonly an inherited condition and mostly seen in small and toy breeds. It occurs when the patella (kneecap) becomes dislocated from its normal position within the groove of the femur (thigh bone).

There is a grading system for patellar luxation, where it is graded 1-4 depending on severity.

Grade 1: The knee cap can be manipulated out of position manually but doesn’t occur spontaneously and causes no clinical symptoms — usually an incidental finding.

Grade 2: The knee cap spontaneously luxates out of position, is typically associated with a skipping lameness when the knee cap moves

Grade 3: The knee cap is out of position most of the time, can be manipulated back into place but will luxate again quickly

Grade 4: The knee cap is permanently out of position and cannot be manipulated into the trochlear groove at all
