Table 1: Mean measurements of patient specific ACL femoral tunnel guides. Distances measured included proximal to distal articular cartilage (distance 1), posterior articular cartilage to femoral footprint (distance 2), distal articular cartilage to femoral footprint (distance 3) and proximal articular cartilage to femoral footprint (distance 4). No statistical significant differences were found in the size of models or the position of the femoral footprint when compared to the computer assisted design or patient MRI. FF = Femoral Footprint. Measurements in mm.
