Multivariate analysis adjusted for the type of graft, surgical portal, associated injuries and age at operation. For the dichotomized variables, the number of events and the percentage of the total number of patients in that particular value interval are presented
SD Standard deviation, IKDC International Knee Documentation Committee, MMT manual maximum test, FTA femoral tunnel angle, CI confidence interval, OR odds ratio, Ns not significant
aMissing patients are patients with incomplete data for the particular analysis, details regarding this can be found in the results section
