title: [Semitendinosus tendon vs. patellar ligament. Results of a prospective randomized study after anterior cruciate ligament reconstruction].
abstract: The aim of our prospective randomised study was to evaluate the clinical results after arthroscopical reconstruction of the ACL using the midthird patellar ligament or semitendinosus tendon.
  
  
  METHODS
  Forty patients were followed up two years postoperatively. Twenty of them received either a patellar ligament graft (BTB-group) or doubled semiteninosus tendon (SET-group). The clinical evaluation included the preoperative and two years postoperative assessment, based on the IKDC-Score, Tegener-Score and Mc-Carroll-Score. The a.p.-translation was evaluated using the KT-1000.
  
  
  RESULTS
  Sixteen (80%) patients of the SET-group and 10 (50%) patients of the BTB-group showed good and excellent results in the over all assessment with the IKDC-Score. The mean side to side KT-1000 difference yielded 1.6 mm (-2-4 mm) in the BTB-group and 2.7 mm (0-7 mm) in the SET-group (p < 0.05). The retropatellar pain syndrome based on the Mc-Caroll-Score showed 17.4 points in the BTB-group in comparison to 19.5 points in the SET-group (p < 0.05). The level of activity using the Tegner-score showed preoperatively for both the SET- and BTB-group 6.9 points and postoperatively for the SET-group 6.7 points and for the BTB-group 5.6 points.
  
  
  CONCLUSIONS
  Despite the inferior a.p.-stability for the patients who received doubled semitendinosus tendon grafts they presented clinically superior results compared to the BTB-group. Therefore this technique seems to be the alternative method. In order to improve the stability we recommend the usage of three or four stranded grafts and an improved fixation technique.
