Anatomical double bundle ACL reconstruction using hamstring tendon graft–clinical evaluation

Abstract

Abstract To evaluate clinically anatomical double bundle ACL reconstruction using Hamstring tendon graft in terms of stability of reconstruction and evaluation by Lysholm score. It was a prospective study with the minimum follow-up of 12 months (1 year). Patients presenting with acute or chronic ACL tear in the orthopedics OPD from March 2007-March 2008 were studied. Forty patients with ACL tear fulfilling the inclusion criteria were operated but 7 were lost in the follow-up, hence 33 patients were included in this study. Thirty-three patients, 27 male and 6 female with 19 right knee and 14 left knee involvement with ACL tear were operated. Arthroscopically, anatomical double bundle (AM and PL bundle) ACL reconstruction with two femoral and two tibial tunnels was done using hamstring tendon grafts. The grafts were fixed with EndoButton CL (Smith and Nephew) fixation system on the femoral side and ligament staple, suture disc or bioscrews on the tibial side. The results were evaluated using Lysholm score and Pivot shift test, which reflected highly significant improvement in the stability, mainly rotational and anterior stability when preoperative score were compared with the score of most recent follow-up i.e. 12 months (p= 0.0001). The average tota l score increased from 1.30 + 0.47-3.00 + 0.56 using Lysholm score. We concluded that Anatomical double bundle ACL reconstruction is an excellent technique for treating patients with ACL tear who are especially involved in the activities/sports, which involve pivoting.
