Surgical Correction of Patellar Luxation in a Cheetah (Acinonyx jubatus)

Abstract

A bilateral, grade 4, medial patellar luxation was diagnosed in a 7-yr-old cheetah (Acinonyx jubatus). The animal had a long standing history of difficulty in rising, bilateral lameness, and reluctance to walk. Radiographs showed severe osteoarthritis and medially displaced patellae. Both knees were operated upon within a 12-wk period. The technique used consisted of desmotomy, exostosis removal, double wedge osteotomy, narrowing of the patella, tibial tuberosity transposition, and fascia lata imbrication. The stability of the patellae was excellent after surgery. The clinical recovery resulted in better ambulation, a lack of lameness, and normal ability to rise 12 wk after the last surgery.
