Contrast arthrography may be performed to delineate subtle dissecting lesions or cartilage flaps. The opposite joint should be radiographed since the disease is often bilateral. Cartilage flaps often do not form in the elbow. OC should be treated by opening the joint, removal of the cartilage flap if present, and deepening of the OC lesion to stimulate fibrocartilage growth. Postoperatively, the animal should be allowed controlled exercise for 2-4 weeks, followed by return to normal function.
Prognosis is dependent on the amount of degenerative joint disease present.
