Introduction. Anterior cruciate ligament rupture is one of the most common
injuries in team sports and its fixation at the tibial site is the weakest
link in the femur-hamstring-tibia structure in anterior cruciate ligament
reconstruction. The aim of this research was to compare the results of knee
stability, knee motion and activity after anterior cruciate ligament
reconstruction with single bundle hamstring tendon graft versus bone
hamstring tendon bone graft placed with different techniques. Material and
Methods. Ninety patients who underwent anterior cruciate ligament
reconstruction were randomly divided into three groups; group I patients
were treated with standard single bundle hamstring tendon graft and standard
operative technique, group II patients had modified single bundle hamstring
tendon graft with bone attachments on both ends which was fixed with
standard method, while group III patients were operated with hybrid fixation
technique at the tibial site and modified graft was used as neoligament.
Results. All surgically treated patients had a statistically significant
improvement post-operatively in comparison with their condition before the
treatment according to the Lachman scale and International Knee
Documentation Committee standard. However, the patients of group III have
achieved statistically significant better postoperative results on Tegner
scale and Lysholm score when compared to group I and II patients. It took
the third group athletes a significantly shorter time to participate in the
first competition after surgery than the athletes from the other two groups.
Conclusion. Hybrid operative technique increased strength and stability of
the graft at the tibial site which accelerated healing process and reduced
knee laxity.
