Knee Model with Pre-made Sockets for ACL Reconstruction – All-Inside Technique (Surgical Training)

## What is this?

A 3D-printable knee model (distal femur and proximal tibia) with pre-made bone sockets reproducing the all-inside technique for anterior cruciate ligament (ACL) reconstruction. In the all-inside technique, closed-ended femoral and tibial sockets are created instead of full tunnels, and the graft is fixed on both sides with cortical suspension buttons.

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 socket placement and orientation in all-inside ACL reconstruction

- Practicing graft passage and suspensory fixation outside the operating room

- Comparing tunnel positions with other ACL techniques in the same series (e.g., transtibial, outside-in)

- Hands-on workshops for medical students and orthopedic residents

## Other materials needed

- Graft substitute: shoelace

- Fixation devices: printable cortical suspension buttons (included in this model)
