Knee Model with Pre-made Tunnels for Combined ACL and Anterolateral Ligament (ALL) Reconstruction (Surgical Training)

## What is this?

A 3D-printable knee model (distal femur and proximal tibia) with pre-made bone tunnels for combined anterior cruciate ligament (ACL) and anterolateral ligament (ALL) reconstruction. In addition to the ACL tunnels, the model includes femoral and tibial tunnels at the anatomical attachment sites of the ALL on the lateral side of the knee, allowing the anterolateral graft to be passed and fixed as an extra-articular procedure to improve rotational control.

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 in combined ACL and ALL reconstruction

- Understanding the anatomical landmarks of the anterolateral ligament on the femur and tibia

- Practicing graft passage and fixation outside the operating room

- 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)
