Background: Anterior cruciate ligament reconstruction (ACL-R) technique affects graft positioning. However, how ACL graft positioning affects graft signal intensity (GSI) is yet unknown. The aim of our study was to find out if ACL-R technique affects GSI at mid-term follow-up. Results: Graft failure was identified in 12.0%. Only 9.8% showed low signal intensity of the entire graft course. Group 2 showed higher rates of increased graft signal intensity (IGSI) of the IAP and fIOP. Patients with IGSI of the IAP showed more horizontal position of the coronal tibial tunnel. Patients with IGSI of the fIOP showed more horizontal position of the coronal femoral tunnel. Patients with IGSI of the tIOP showed more horizontal position of the sagittal tibial tunnel. Conclusion: IGSI can be seen in the majority of patients after ACL-R at mid-term follow-up. Our study demonstrates that graft tunnel positioning and graft fixation device may influence GSI.
