Poster 332: Return to Sport, Post-Operative Performance Testing, and Re-injury Rates Among Athletes Treated with Hamstring, Quadriceps, and Patellar Tendon Autograft ACL Reconstruction

Objectives: Anterior Cruciate Ligament (ACL) tears are a common sporting injury and optimal graft choice is of concern for both patients surgeons. Few comparative studies have evaluated return to sport reinjury rates across types. The purpose the present study was evaluate reinjuries among hamstring tendon (HT), quadriceps (QT), patellar (BPTB) ACL reconstructions. Methods: Recreational competitive athletes ages 13-24 from 2010-2022 that underwent primary or revision reconstruction were included. There 837 total comprised 341 HT, 358 BPTB, 138 QT autografts, which 729 108 surgeries. Return (RTS) rates, RTS testing results, clearance time, collected. data included isokinetic quadricep strength functional movement screening. A Kruskal-Wallis test used detect differences continuous variables. GLIMMIX procedure completed multivariate analysis between groups after adjusting age activity level. Chi-square statistics Fisher’s exact categorical Odds ratio, adjusted odds 95% confidence intervals provided by logistic regression. All statistical analyses performed using SAS 9.4 (Cary, NC). Statistical significance measured at p<0.05. Results: median 18 HT BPTB 17 (p= 0.0001).
