Hyperextension of the bilateral knees in a 1-day-old neonate • no knee fractures or dislocation on x-ray • Dx?

THE TAKEAWAY

Congenital genu recurvatum is a rare condition that presents with abnormal hyperextension of the knee(s) with limited flexion. Early diagnosis and assessment of the severity of the hyperextension is crucial in determining the type of intervention to pursue. Conservative management entails serial casting and splinting to increase knee flexion. If conservative management fails or if the diagnosis is made later in life, surgical options often are pursued.
