Arthroscopic Reconstruction of Anterior Cruciate Ligament by Hamstring Graft; Endobutton vs Rigidfix

Introduction: Anterior cruciate ligament (ACL) tear is a common sport injury. In recent years hamstringligaments have become the most widely used graft for ACL reconstruction. One important issue is type offemoral side graft fixation. We compared the clinical outcomes of two femoral side fixation methods,endobutton and Rigidfix.Methods: From March 2014 to March 2016, 147 patients with ACL tear were treated by arthroscopicACL reconstruction using autogenous quadruple hamstring graft. Femoral side fixation was performedwith endobutton or Rigidfix. Demographic and perioperative data were collected from hospitaldocuments. Patients were evaluated using objective and subjective International Knee DocumentationCommittee (IKDC) and Lysholm Knee Scores.Findings: 87 (59%)cases (48 endobutton and 39 Rigidfix) were accessible for final evaluation. Meanduration of follow up was 18(range 17-22) months. There was no significant difference between twogroups regarding age, gender, body mass index (BMI), damage mechanism, activity level andpostoperative pain, limp, subjective IKDC and Lysholm scores. Pivot shift test was normal in all cases ofboth groups. Anterior translation of more than three millimeter in comparison with intact knee in 30o and90o of flexion was seen in 3(6.25%) and 3(7.69%) of endobutton and Rigidfix cases,respectively.Conclusion: There was no significant difference between endobutton and Rigifix using subjective scores.Rotary and anteroposterior stability was similar. Both fixation methods result in a stable knee.
