[Bilateral spontaneous patellar tendon rupture]

Abstract

Ruptures of the patellar tendon are less often observed compared to those of the Achilles or quadriceps tendon. A bilateral rupture is a rarity. Steroid medications or a variety of systemic diseases are associated with spontaneous tendon ruptures. Less often traumatic rupture is the result of severe overloading of the extensor mechanism of the knee. We report on a 60-year-old female without an obvious trauma, systemic disease or medication who suffered a spontaneous bilateral patellar tendon rupture.
