Spontaneous bilateral rupture of the quadriceps tendons without a significant history of trauma is an uncommon disease. It is generally associated with mechanical factors and coexisting systemic and local factors are taken into consideration in the pathogenesis of these ruptures. In patients with some chronic systemic diseases, simultaneous rupture can occur spontaneously or with minor trauma. We present a case of patient with chronic renal failure on hemodialysis for the past 9 years, who sustained this injury, and subsequently had surgical repair of both tendons. We performed a preoperative magnetic resonance imaging to confirm the diagnosis, then we repaired the ruptured quadriceps tendons and performing MRI postoperatively 1 yr later. He regained his normal knee joint functions 1 yr after the operation.
