PurposeThe purpose of the current study is to investigate in different femoral fixation devices whether tight (undersize drilled) fit technique decreases the tunnel widening and improves the clinical outcome compared to conventional technique in ACL reconstruction using hamstring tendon autograft.Methods93 patients, who underwent Arthroscopic ACL reconstruction whether cortical-cancellous suspension (CP) or cortical suspension (BF) used as fixation device for the hamstring tendon autograft, were included in the study. The cases also grouped as undersize drilled (tight fit) and normal drilled (normal fit) according to their autograft size. There was no difference in demographic data of these four subgroups (CP-TF, CP-NF, BF-TF, and BF-NF) preoperatively.ResultsThe patients, who had been followed for at least 2 years were included in the study. They were looked for their clinical outcome (Lysholm and IKDC scoring), tunnel widening (on AP and lateral radiographs), and also anterior translation. The BF-TF subgroup showed significantly the best clinical results compared to other three subgroups. There was no difference between BF-TF, CP-TF, and CP-NF in terms of tunnel widening.ConclusionButton fixation of femoral side in ACL reconstruction surgery has good clinical outcome and lower complication rate. Undersize drilling might be preferred in button fixation in order to reduce TW and improve stability and clinical satisfaction.Level Of EvidenceTherapeutic case series, Level IV.
