Title : Surgical correction of lateral patellar luxation in a pileated gibbon (Hylobates pileatus)
Authors : H. POUILLEVET, X. FERREIRA, M. GIORGIADIS, B. LEFAUX, B. QUINTARD
Summary : A twenty-six-year-old pileated gibbon (Hylobates pileatus), weighing 8.3kg, was presented with change in the locomotion mode and ischial pressure sores. On examination and radiographs, a grade-3 lateral patellar luxation of the right hind limb was diagnosed. Surgical correction involving a medial tibial tuberosity transposition and a medial retinacular imbrication was planned. An additional trochleoplasty was decided intraoperatively because arthrotomy revealed a flat femoral trochlear groove: the trochlea was surgically deepened, and the removed wedge of cartilage was replaced in the groove. The gibbon recovered its hind limb use one month after surgery, but pressure sores persisted. It finally died of contagious digestive infection 43 days after surgery. Patellar luxation is a common disorder of the stifle in dogs and cats, but very little is known about this disorder in non-human primates. Only one elbow luxation and one radial luxation have been reported. To the authors' knowledge, this is the first description of a patellar luxation and its management in a gibbon.
