Comparison of different methods of femoral fixation anterior cruciate ligament reconstruction

ABSTRACT

The aim of this study is to compare three modes of femoral fixation, namely Aperfix, Rigidfix and Endobutton, in anterior cruciate ligament [ACL] reconstruction. 120 patients were randomly assigned to three groups, each consisting of 40 patients, and each group was treated by one of the above mentioned methods of femoral fixation. All patients were examined prior to and 24 months after surgery, and they were compared for anterior tibial displacement using the Lysholm score and KT-1000. The three modes of femoral fixation were not significantly different in terms of time of surgery. In the Endobutton group, the Lysholm score rose from 63.21 +/- 18.59 prior to ACL reconstruction to 90.64 +/- 9.47 after the surgery, while it rose from 65.72 +/- 18.74 to 96.22 +/- 5.35 in the Aperfix group and from 69.21 +/- 17.45 to 90.64 +/- 9.47 in the Rigidfix group. Anterior tibial displacement was 3.96 +/- 1.58 mm for Endobutton, 4.28 +/- 1.48 mm for Rigidfix and 4.03 +/- 1.79 mm for Aperfix. Aperfix was indicated to yield a better outcome in terms of instant stability and general results:
