Bilateral congenital absence of patella

Indian J Orthop. 2008 Apr;42(2):228-30. doi: 10.4103/0019-5413.40264.

Abstract

Absence of patella as an isolated anomaly is extremely rare. It is usually absent as part of a syndrome, most commonly hereditary arthro-onchyo-dysplasia (Nail Patella Syndrome). We present a case of congenital bilateral absence of patella in a nine-year-old boy with no associated anomalies.
