From: Remnants-preserving ACL reconstruction using direct tendinous graft fixation: a new rat model
Intra-articular, tibial and femoral sections planes used for micro-CT and histological bone tunnels analysis. The bone tunnels (black dotted lines), autograft (green), ACL remnants (striped yellow), and fixation screws (blue) are represented. Note the direct fixation of the graft provided by the “outside-in” insertion of the cortical screws into the bone tunnels. Screws are represented here for a better understanding, but they were removed before performing the postmortem analysis; thus, only the screw holes were visible on micro-CT and histology sections
