Aim: To measure the tibial and femoral footprint of ACL in Indian patients (with and without ACL injury) using MRI of normal patients, during (ACLR) and during TKR. Materials and Methods: The present prospective study was conducted at PD HINDUJA hospital and medical research center, Mumbai from March 2015 to November 2015 among 100 patients of Indian origin undergoing arthroscopy, TKR and MRI in our hospital. We have taken three separate patients group undergoing different procedure related to knee i.e. Group 1 (Arthroscopic ACL reconstruction), Group 2 (Total knee replacement) and Group 3 (Diagnostic MRI). As MRI are done in extension of knee, femoral footprint was in vertically oval plane, so calculating length of maximum Supero-inferior measurement on MRI sequence of femoral footprint was giving us length of femoral footprint. All above-mentioned readings were added in tabular form in excel sheet master chart and was statistically analyzed using SPSS software version 24.
