Background: Preservation of hamstring tendon insertion at the time of anterior cruciate ligament (ACL) reconstruction is a well-known technique; however, its effect on graft integration is not well studied. The present study was conducted to study the graft integration inside the tibial and femoral tunnels, respectively, after ACL reconstruction using hamstring tendon graft with preserved insertion.
Methods: Twenty-five professional athletes who underwent ACL reconstruction using hamstring tendon graft with preserved tibia insertion were enrolled in the study. Functional outcomes were checked at final follow-up using Lysholm score and Tegner activity scale. Magnetic resonance imaging (MRI) was done at 8 months and 14 months follow-up to study the graft tunnel integration of the ACL graft at both tibial and femoral tunnels.
Results: The mean Fibrous interzone (FI) score (tibial tunnel) decreased from 2.61 (1?5) at 8 months to 2.04 (1?4) at 14 months follow-up (p?=?0.02). The mean FI score (femoral side) decreased from 3.04 (2?5) at 8 months to 2.57 (2?4) at 14 months (p?=?0.02).
Conclusions: Graft integration occurs early in the tibial tunnel as compared with the femur tunnel with preserved insertion hamstring tendon autograft.
