In this article we report a very rare case of simultaneous and bilater
al rupture of the quadriceps tendon in a 38-year-old patient. The init
ial diagnosis was ''herniated vertebral disk''. Although there was an
extensive neurological and psychiatric examination in combination with
several operations, it took almost 3 months until the real reason was
found. In this case report we describe our postoperative treatment of
early mobilization and compare it with other therapies.
