Knee Model with Pre-made Tunnels for Posterolateral Corner Reconstruction – LaPrade Technique (Surgical Training)

## What is this?

A 3D-printable knee model (distal femur, proximal tibia and fibula) with pre-made bone tunnels reproducing the LaPrade technique for anatomic posterolateral corner (PLC) reconstruction. The technique reconstructs the three main static stabilizers of the posterolateral corner – the fibular collateral ligament (FCL), the popliteus tendon (PLT) and the popliteofibular ligament (PFL) – using femoral tunnels at the FCL and popliteus attachments, a fibular head tunnel and a 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 in anatomic posterolateral corner reconstruction

- Understanding the anatomy and attachment sites of the FCL, popliteus tendon and popliteofibular ligament

- Practicing graft passage and fixation outside the operating room

- Hands-on workshops for medical students and orthopedic residents

## Other materials needed

- Graft substitute: shoelaces (different colors help to identify each reconstructed structure)

- Fixation devices: interference screws (printable version available in this series)
