Open ankle models project

We are developing a new open-source simulation tool to improve our understanding and treatment of ankle injury.

Project status

In progress


1 Apr 2022 to 1 Apr 2024

3D computer model of the ankle bones including tibia, fibula, talus, calcaneus, and navicular.
Researchers will be able to use the models which we hope will lead to better treatments of ankle injury.

Have you ever injured your ankle? Approximately 2% of people will damage their ankle at some point in their lifetime, and this often leads to further issues later in life. In this project, we seek to improve treatment and understanding of ankle injury using computer simulation.

We are developing a new open-source simulation tool that can be used by clinicians in collaboration with engineers to test out different treatments. We'll create the models with input from the biomechanics and orthopaedic communities to optimise usability. Researchers will be able to download and use the models for free using open-source software. Our vision is that this will facilitate and standardise ankle joint modelling, leading to more innovative and successful treatments of ankle injury.


Timeline of the project. April 2022 project begins. November 22 first model created. April 2023 round robin trial starts. November 2023 model refinement based on feedback. March 2024 model launch event. April 2024 project end.

Data download and guides

We are currently developing our model data and guides but will provide links to access the data at the end of the project.

If you are a biomechanics researcher or clinician and would be interested to test-drive our models, we will be running a round-robin trial in Spring 2023. Please email us to find out more.
