306 Anterior Cruciate Ligament Graft Rupture: Analysis of Anteromedial Versus Trans-Tibial Portal Technique for Femoral Tunnel Placement in 473 Patients

Abstract Introduction Correct femoral tunnel position in anterior cruciate ligament reconstruction (ACLR) is critical obtaining good clinical outcomes. We aimed to delineate whether any difference exists between the anteromedial and trans-tibial portal placement techniques on primary outcome of ACLR, graft rupture. Method Adult patients (>18 years old) who underwent ACLR January 2011 - 2018 were identified divided based technique (anteromedial v trans-tibail). The measure was Univariate analysis used association independent variables outcome. Binary logistic regression utilised odds ratios significant variables. Results 473 analysed. Median age at surgery 27 old (range 18-70). 152/473 (32.1%) group compared 321/473 (67.9%) trans-tibial. 25/473 (5.3%) sustained time rupture 12 months (IQR 9). A higher odd for associated with group, which trended towards significance (OR 2.03; 95% CI 0.90 4.56, p = 0.081). Conclusions There no statistically rates when comparing placement. a trend group.
