Poster 249: Low Failure Rate in a Young Cohort of Patients Undergoing Anterior Cruciate Ligament Reconstruction with Quadriceps Tendon is Independent of Graft Fixation Methods

Objectives: To determine failure and clinical outcomes of anterior cruciate ligament reconstruction (ACLR) with quadriceps tendon in a young cohort patients, and, secondarily, if method femoral tibial fixation the graft affects these outcomes. Methods: All patients aged 10-30 years old who underwent primary ACLR autograft from 2010 to 2021 were retrospectively analyzed. Patients double-bundle ACLR, posterolateral corner augmentation, revision excluded. Patient demographics, surgical details, failure, pre- post-operative International Knee Documentation Committee (IKDC) scores recorded. The outcome was secondary post- operative IKDC score. further categorized into three groups based on fixation: suspensory/suspensory (Group 1), suspensory/aperture 2), aperture/aperture 3). Suspensory included fixed loop, adjustable screw washer fixation, whereas aperture use interference screw. Chi Squared analyses used analyze categorical outcomes, ANOVA Kruskal-Wallis tests continuous Significance set at p < 0.05. Results: A total 350 for analysis. average age 19.4 (+/- 4.3) old, follow-up length 12.6 7.0) months. BMI, sex, laterality procedure statistically similar. rate 4.9% overall, mean score almost two times higher than pre-operative (76.2 vs 38.8, respectively). When dividing type, 122 had suspensory 191 37 fixation. similar across (6.6% (1), 4.7% (2), 0% (3); > 0.05). Further, did not differ significantly (74.2 77.1 79.2 Conclusions: Results this study suggest that is viable option ACL as demonstrated by low marked increase post-operatively. interval short, however, slightly increased rates may be observed over time. Femoral methods influence or scores, suggesting they play role success following ACLR. Surgeons utilize information during planning discussion options their patients.
