Clinical Comparison of Patients Undergoing Anterior Cruciate Ligament Reconstruction Using an Allograft or Autograft

Abstract

Aim: The purpose of this study was to examine the clinical results of individuals who underwent an autograft or allograft repair of the anterior cruciate ligament (ACL). Material and Methods: Retrospective analysis was done on the patient files of patients who underwent ACL reconstruction between 2014 and 2020 using semitendinosus-gracilis tendon autografts (SGT-A) and tibialis anterior tendon allografts (TAT-A). In this study, the data of 30 patients in each group were included. Knee laxity tests, the Lysholm knee grading system, the Tegner activity score, and the International Knee Documentation Committee (IKDC) score were used to compare patient results. Results: While there was no significant difference in the Tegner activity score between the preoperative and the final measurement (p=0.241), the IKDC scores and the Lysholm knee ratings changed statistically significantly between the preoperative measurement and the last control visit (p=0.020, and p=0.038, respectively) for both groups in this study. The SGT-A group’s Lysholm knee score had a preoperative value of 60.97% and a final control value of 90.48%. The preoperative Lysholm knee score for the TAT-A group was 61.31%, and the final control value was 95.03%. The anterior drawer and Lachman test findings showed statistically significant intergroup (autograft and allograft) alterations in both the autograft and allograft groups (both p<0.001). Conclusion: In terms of knee function and laxity, this study achieved a better clinical outcome in the allograft group compared to the autograft group.
