title: Bilateral congenital absence of patella.
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.
