“…When patellar abnormalities are suspected, lateromedial, caudoproximalcraniodistal oblique and craniodistal-cranioproximal (skyline) oblique radiographic views are commonly used to assess the stifle joint and position of the patella (O'meara & Lischer, 2009). Surgical repair of congenital patellar luxation carries a good prognosis in miniature horses and foals; however, most foals affected with congenital limb malformations such as ectopia, hypoplasia, aplasia, haemimelia or agenesis have a poor to grave prognosis, depending on the affected structures (Bertone & Aanes, 1984;Busschers 2009;DeBowes & Leipold, 1984;Finocchio & Guffy, 1970;Leipold & Macdonald, 1971;Modransky et al, 1987;Robbe et al, 2012;Silva et al, 2014;Van Pelt et al, 1971). In man, congenital patellar aplasia or hypoplasia is a rare autosomal dominant disorder, occurring in only a few families, and often does not cause major dysfunction (Sferopoulos, 2018).…”

A 2-day-old Cleveland Bay colt was referred to the Equine Emergency Service of the Farm Animal and Equine Veterinary Medical Center at North Carolina State University's College of Veterinary Medicine for evaluation of decreased nursing behaviour and right hindlimb lameness of 2 days' duration. When assisted to stand, the foal was unable to extend either hindlimb or bear weight on the hindlimbs, the right patella was luxated laterally and unable to be reduced, and the foal assumed a crouched position.Stifle radiographs revealed minimal, heterogeneous, ill-defined ossification of both patellae. Due to the severity of the musculoskeletal defects, humane euthanasia was elected. Post-mortem examination identified a congenital malformation of both patella bones with failure of ossification and cardiac changes suggestive of right atrioventricular valve dysplasia. Histology of the patellae showed no evidence of osteoid deposition or ossification. To our knowledge, bilateral congenital patellar aplasia has not been previously described in foals.
