Bilateral Stifle Osteochondritis Dissecans in a Cat

Abstract

A 13-month-old neutered female American domestic shorthair cat was presented for evaluation of bilateral pelvic limb lameness of 9 months' duration. A diagnosis of bilateral stifle osteochondritis dissecans was made from the physical and radiographic examination findings. Cartilage fragments and flaps were found in both stifle joints during bilateral stifle arthrotomy. The affected subchondral bone was curetted. The clinical signs improved after this surgical treatment, and the cat had a normal range of motion in both stifle joints on the physical examination 3 years postoperatively.
