Intermittent fixation of the patella on the upper part of the femoral trochlea results in a characteristic jerky action of one or both hindlimbs. The limb remains in caudal extension for a longer period than normal and may even be dragged for a few steps before clicking forward to a normal posture. In young animals, the condition may resolve spontaneously. For luxations that do not resolve, medial patellar desmotomy should be performed.
