Poster 344: Reduced Incidence of Anterior Cruciate Ligament Reconstruction Revision with Internal Brace Augmentation: A Retrospective Matched Cohort Study with a minimum 2-year Follow-up

Objectives: The primary purpose of this study was to investigate retear rates in patients who underwent ACLR with and without internal bracing a matched cohort study. Additionally, we also sought if there were any differences clinical patient-reported outcomes between the groups. We hypothesized that would reduce incidence revisions safe effective manner. Methods: A total 200 included Patients ages 13-39 at time surgery autograft (IB group) October 2010 July 2020 enrolled our institution’s registry minimum 2-year follow-up identified 1:1 non-internal brace (no-IB) group based on patient demographics concomitant procedures. Every completed Knee Injury Osteoarthritis Outcome Score (KOOS), Marx Activity Rating Scale (MARS), Veterans RAND 12-Item Health Survey (VR- 12), Visual Analog (VAS) pre- postoperatively. KT-1000 arthrometer measurements postoperative objective, assessments. Results: IB significantly less revision ACLRs (1% vs. 8%, p = 0.017). average elapsed from original did not differ for no-IB groups comparable (19.0-years-old 19.9-years-old). 5 9 meniscal procedures among them their compared just one (p 0.009). There 4 anterolateral ligament reconstruction (4 0, 0.043). All outcome measures (PROMs) increased both exception MARS score which decreased improved following cohorts yielding results manual maximum pull (0.97mm 0.65mm). Conclusions: resulted an 88% decrease while maintaining reported outcomes. Incorporating Internal into is therefore within these parameters. [Table: see text][Table: text]
