title: [Internal rotational strength of the thigh after ACL reconstruction. Prospective comparison of harvesting of the semitendinosus and gracilis tendons and the patella tendon].
abstract: OBJECTIVE
  The aim of the present study was the prospective, randomized evaluation of the internal rotation strength in patients, undergoing ACL reconstruction using either semitendinosus and gracilis tendon autografts (ST/G) or the central third of the patella tendon (BPT).
  
  
  METHODS
  40 patients (20 male, 20 female, average age 32 years [16 - 49]) underwent reconstruction of the ACL. In 20 patients ST/G was used, in 20 matched patients the central third of the patella tendon (BPT) was used. Rehabilitation was identical for both groups. The isometric strength of internal tibial rotation in neutral position was measured preoperatively, 3, 6 and 12 months postoperatively.
  
  
  RESULTS
  After 3 months no difference to the preoperative data was found. After six months the internal tibial torque was significantly higher (p < 0.05) than preoperatively. No additional increase was found after 12 months. There was no statistically significant difference between both groups at any time.
  
  
  CONCLUSIONS
  The internal tibial torque, which is predominantly a function of the pes anserinus, recovers shortly after operation and is, due to postoperative rehabilitation, significantly elevated after 6 months. The randomized comparison with the harvesting of the central third of the patellar tendon showed no significant difference.
