Chapter 7138were judged for its fit, see Figure 3 (right bottom). The guides were judged upon the type of fit by two orthopedic surgeons with experience in ACL reconstruction. The type of fit was rated by each orthopedic surgeon on a 5 point Likert scale, 1 meaning a very poor fit and 5 meaning a very good fit. The orthopedic surgeons judged the type of fit independent of each other.Next a femoral tunnel was drilled using the guide when accurate positioning based on tactile and visual feedback was confirmed. After the experiment, the same MRI protocol was performed as before which allowed for comparison of the actual drill trajectory with the Figure 3. The patient specific 3D printed femoral aiming guide. (a) The drill trajectory aims for the pre-determined ACL origin (b) the aiming device fits the medial wall of the lateral femoral condyle anatomically (detailed view).
