## What is this?
A 3D-printable knee model (distal femur and proximal tibia) with pre-made bone tunnels reproducing the outside-in technique for anterior cruciate ligament (ACL) reconstruction. In the outside-in technique, the femoral tunnel is drilled from the lateral femoral cortex toward the intra-articular footprint, independently of the tibial tunnel.
This model is part of a series of knee ligament reconstruction models developed by the orthopedic surgical simulation group of Hospital de Clínicas – Universidade Federal do Paraná (UFPR) and the 3D Printing Laboratory of the Centro de Simulação Profª Leide Parolin Marinoni, Curitiba, Brazil.
## What is it for?
- Teaching tunnel placement and orientation in outside-in ACL reconstruction
- Practicing graft passage and fixation outside the operating room
- Comparing tunnel positions with other ACL techniques in the same series (e.g., transtibial)
- Hands-on workshops for medical students and orthopedic residents
## Other materials needed
- Graft substitute: shoelace
- Fixation devices: interference screw and/or cortical suspension button (printable versions available in this series)
