Simultaneous Bilateral Quadriceps Tendon Rupture in an Adult Man


Case Presentation: A previously healthy 45-year-old man presented to the emergency department with bilateral knee pain and inability to extend his knees after a slip and fall on ice. The clinical diagnosis of bilateral quadriceps tendon rupture was confirmed by computed tomography (CT) of bilateral knees. The patient underwent successful operative repair the following day.

Discussion: Bilateral quadriceps tendon rupture is rare and can be difficult to diagnose due to the impossibility of comparing the affected to the unaffected limb. Plain radiographs are usually not helpful, but ultrasound, CT, and magnetic resonance imaging may be used to confirm the clinical diagnosis.
