Fig. 3From: Outcomes of human umbilical cord blood-derived mesenchymal stem cells in enhancing tendon-graft healing in anterior cruciate ligament reconstruction: an exploratory studyThe volumes of three-dimensional (3D)-reconstructed models were measured using Mimics software. A Transparent image obtained through a 3D-reconstructed model of the femur showed the AM and PL tunnel postoperatively. B The widening of the tunnel was clearly observed at 12 months, especially in the AM tunnel. C The tunnel was separated from the 3D-reconstructed model. D, F The volume of the AM and PL tunnel was estimated using Mimics softwareBack to article page
