title: Reconstruction of the anterior cruciate ligament: a clinical comparison of bone-patellar tendon-bone single bundle versus semitendinosus and gracilis double bundle technique.
abstract: The study hypothesis was that the outcome of semitendinosus gracilis double bundle (STG-DB) anterior cruciate ligament (ACL) reconstruction is advantageous in terms of clinical results and restoration of anterior-posterior and rotational laxity in comparison to bone-patellar tendon-bone single-bundle (PTB-SB) ACL reconstruction. We analysed 41 PTB-SB and 51 STG-DB patients using the Tegner, IKDC and WOMAC scores preoperatively and at a minimum follow-up of two years. At follow-up, there was no significant difference in the clinical scores. The KT 1000 side-to-side measurement showed no significant difference between groups. The STG-DB group was significantly superior in terms of the pivot-shift sign and anterior knee pain. We conclude that the outcome of STG-DB reconstruction in the mid-term was not advantageous in terms of clinical scores and anterior-posterior laxity evaluated by the KT 1000. Nevertheless, the restored rotational laxity measured by the pivot shift test was significantly superior in the STG-DB technique.
