[Simultaneous traumatic rupture of the patellar and contralateral quadriceps tendon].

We report a very rare case of a simultaneous rupture of the right patellar and left quadriceps tendon in an otherwise healthy 37-year-old patient, who jumped off a kickboard. Suture of both tendons was performed on the day of trauma. We describe our postoperative treatment and report the follow-up examination one year after the trauma. Beside functional questionnaire, Lysholm score and physical examination and x-ray, quadriceps isokinetic testing was performed.
