Abstract

Background:

The type of graft for anterior cruciate ligament (ACL) reconstruction is still a topic of debate and there is still no clear consensus on the ideal graft for ACL reconstruction.

Purpose:

This study was conducted to compare the outcome of ACL reconstruction surgery between hamstring tendon graft and bone-patellar tendon-bone (BPTB) graft.

Materials and Methods:

One hundred and sixty professional athletes were enrolled in the study. They were divided into two groups by computerized randomization. In Group I, ACL reconstruction was done using BPTB graft, and in Group II, ACL reconstruction was done using semitendinosus gracilis graft with preserved tibial insertion (STGPI). Postoperatively, patients were assessed for knee stability, Lysholm score, and WOMAC score.

Results:

Mean KT-1000 side-to-side difference at 1 year was 2.31 ± 1.68 mm in BPTB cohort and 2.52 ± 1.6 mm in STGPI cohort (P = 0.4); and at 2 years, it was 1.98 ± 1.62 mm in BPTB cohort and 2.23 ± 1.6 mm in STGPI cohort (P = 0.4). Mean Lysholm score at 2 years was 96.1 ± 5.81 in STGPI cohort and 97.3 ± 4.62 in BPTB cohort (P = 0.15). Mean WOMAC score at 2 years was 3.3 ± 2.76 in STGPI cohort and 2.84 ± 2.21 in BPTB cohort (P = 0.25). Graft rupture rate was 3.75%; 3 patients in each group had graft rupture. Kneeling pain was present in 15% (12/80) of patients with BPTB graft whereas none of the patients in STGPI cohort had kneeling pain.

Conclusion:

There was no difference between two grafts in term of knee stability, visual analog scale score and functional outcome. However, hamstring tendon graft is associated with less donor site morbidity.
