[Spontaneous bilateral quadriceps tendon rupture in obese patient medicated with statin].

Bilateral quadriceps tendon rupture (BQTR) is a rare diagnosis only reported in about 100 cases in international literature, and is often associated with medical diseases, trauma or certain medications. We present a 64-year-old man with spontaneous BQTR, diagnosed and treated at our hospital. His risk factors were obesity (BMI = 30.95 kg/m2), statin use, and recreational tennis at time of injury. The diagnosis of BQTR is difficult and is often missed initially. There is also emerging thoughts that the use of statins may be a risk factor for BQTR. The evidence, however, is scarce.
