Clinical Outcome of Arthroscopic Assisted Transcondylar Fixation Versus Endobutton Fixation in ACL Reconstruction

Abstract

Objective: The aim of this study was to compare the clinical results of arthroscopic assisted ACL reconstruction using transcondylar screw fixation and endobutton fixation in term of postoperative knee stability and knee functional score.

Methods: Thirty five patients, 20 in transcondylar screw fixation group and 15 endobutton fixation group, were reviewed. Both groups had similar pre-operative data. The average follow-up time was 7 months.

Results: This study found that there was no significant difference in post-operative knee stability tested by Lachman test and pivot-shift test between both groups. The median post-operative knee functional scores, Lysholm scores (93 in the transcondylar group versus 90 in the endobutton group, p > 0.05) were not significantly different between both groups. Both groups had also significantly improved knee stability and knee functions (Lysholm scores), post-operatively.

Conclusions: Arthroscopic assisted anterior cruciate ligament reconstruction used transcondylar screw fixation or endobutton fixation resulted indifferently in significant improvement of knee stability and function.
