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.
After months or years of abnormal movements, the groove can wear down, allowing the knee cap to dislocate. When the knee cap dislocates, it can't go back to its original position until your dog's thigh muscles relax. This is why affected dogs sometimes hold the affected leg up after the initial incident. The pain is caused by the patella sliding across bony ridges on the femur.
