Suspensory fixation versus novel transverse crosspin for femoral fixation in anterior cruciate ligament reconstruction

Abstract

Background and aim: There is still no gold standard technique for graft fixation during anterior cruciate ligament reconstruction. We compared the functional outcomes of patients receiving either ToggleLoc with ZipLoop technology or Translig transverse crosspin device for femoral graft fixation.Materials and methods: A total of 118 patients were randomly allocated into two groups to receive either Translig® transverse crosspin (Translig group 1: n = 51, mean age 28.34 ± 7.83 years, age 18–40 years) or ToggleLoc with ZipLoop technology (ToggleLoc group: n = 67, mean age 26.85 ± 8.76, age 16-41 years) for femoral graft fixation. Early and 1-year assessment was made with Lysholm knee scale, International Knee Documentation Committee Scoring, Tegner Activity Level Scale, KT-1000 arthrometer and pivot shift test.Results: Preoperative vs. postoperative functional parameters showed significant improvement in both groups. Two groups were similar in terms of Lysholm knee scale, IKDC and Tegner activity scores (p > 0.05). The KT-1000 arthrometer revealed slightly less anterior sliding in Translig group than that in ToggleLoc group (p > 0.05). ToggleLoc technique allowed a radiographically more horizontal placement of the graft than Translig technique.Conclusion: Two distinct techniques used in this study are likely to be suitable for femoral graft fixation during anterior cruciate ligament reconstruction with the femoral tunnel being created via anteromedial approach. © 2014, Springer-Verlag Berlin Heidelberg.
