title: [Ultrasonography as a diagnostic tool in cases of quadriceps tendon rupture].
abstract: OBJECTIVE
  Determination of the reliability of ultrasonography as a diagnostic tool for rupture of the quadriceps tendon and for follow-up after surgical repair.
  
  
  METHODS
  11 patients (12 tendons) with a clinical suspicion of quadriceps tendon rupture were studied with ultrasonography in two planes.
  
  
  RESULTS
  In 9 cases we were able to confirm the results of the clinical examination using ultrasonography. In 2 cases we did not find a rupture of the quadriceps tendons ultrasonographically. Within the postoperative follow-up, the homogeneity and echogeneity normalised after the sixth week.
  
  
  CONCLUSIONS
  Using ultrasonography we are able to clearly diagnose ruptures of the quadriceps tendon and objectively assess the postoperative follow-up.
