[Bilateral rupture of the quadriceps tendon--case report and review of the literature].

We report a very rare case of bilateral simultaneous rupture of the quadriceps tendons in a 64-year-old patient following a minor trauma. The reconstruction of the ruptured tendons was achieved by intertwined PDS-sutures which were supportively fixed in the patellae. After wound healing, the patient was mobilized in his two casts which were applied for 6 weeks. After the period of one year, a satisfactory result could be seen. We report the etiology, pathogenesis, diagnosis, therapy and postoperative treatment which are described in the literature.
