Biweekly Meeting of Cleveland Clinic Core Team
Date: June 12, 2018
Time: 12:00 PM EST
Means: In person meeting
- Ahmet Erdemir
- Snehal Chokhandre
- Erica Neumann
- Ariel Schwartz
- Rodrigo Lopez-Navarro
- Discuss Open Knee(s) progress.
- Discuss Knee Hub progress.
- Open Knee(s)
- Snehal made all the recommended changes to the MRI data manuscript and has received confirmation for the data DOI. She will submit the manuscript ASAP.
- Snehal completed the conversion of Open Knee(s) generation one model to version 2.5. She will run it and document modification etc. needed to run the model. Once successfully run, the model will be disseminated.
- Snehal will focus on the cartilage manuscript for submission by early September.
- She will also start efforts to run Open Knee(s) models in parallel with Knee Hub.
- Ahmet and Snehal met Dr. Paul Saluan (Advisory Board member) to provide update on the Open Knee(s) progress. He offered to help review sample segmentation (particularly ligaments) to confirm whether our identification of tissues is correct. Snehal will arrange a meeting in the upcoming weeks.
- Rici is working on python scripts to process joint data in user readable form. The goal is to have the scripts ready by December 2018.
- Rodrigo gave an update on his work. He has started working on writing python scripts to calculate ligament length changes under various joint motions (using Rici's scripts to extract information from joint testing data files and animate the tibia-femur motion). The script works for ACL and PCL so far but not for MCL. Ahmet recommended using a bounding box to identify the major axis.
- Knee Hub
- Ahmet sent a reminder to the co-investigators for completing the phase 1 specifications.
- Specifications documented by Ariel for Cleveland Clinic team were discussed.
- May use implicit static simulation (bone density not needed).
- Ligament densities were taken from generation 1 documentation.
- Ariel added fiber direction description.
- Quadriceps tendon properties are not decided yet.
- For menisci, the fiber direction will be along the tangent to a circle fit to the menisci geometry.
- For in situ strain, an average value will be used for each ligament.
- Python scripts will be developed to update the template model.
- Passive flexion application: along flexion axis, all other forces zero, all other cylindrical joints set free.
- Patellofemoral joint will also be defined.
- Spring may be defined to represent MPFL for now.
- None noted.
