- Curation of outcomes from Model Benchmarking (including Recalibration) and Model Reuse.
- Planning of manuscripts for Model Benchmarking and Model Reuse.
- Mobilizing for potential renewal.
- Presence in ORS 2023 meeting.
- Other
Immediate Action Items:
- Jason
- Submit Model Reuse specifications.
- Work on Model Reuse outcomes.
- Carl
- Follow up in regard to decision on ORS workshop manuscript.
- Follow up with Shady on Model Benchmarking and Reuse packages.
Thor & Kevin
- Collect reviews for Model Calibration manuscript and update as needed.
- Nynke
- Pull data from Model Development manuscript to share with DU group.
- All
- Review Model Calibration manuscript ensuring their approach and data are represented properly.
- Schedule meeting on ligament anatomy representation.
- Promote project at ORS meeting.
Notes:
- ORS workshop paper was reviewed, Carl has been waiting for formal response.
- Calibration manuscript was written, it should be reviewed by co-authors. The teams should also check if their approach and data are represented properly. Ahmet noted the disparity in the figure which labeled reference strain, whereas the data appeared to be for reference stretch. The group will collaboratively edit in MS One Drive. DU group will share the document. Carl wondered what matters when it comes to calibration differences. Can we provide a message in this regard, e.g. consensus on the ideal way vs the pragmatic way. The group agreed that primary challenge and burden in calibration is related to computation. Per Thor, elaborating these may leading towards benchmarking. DU group also asked for Model Development data for passive flexion (full trajectory) in order to provide model prediction capacity for anterior translation and varus/valgus before and after calibration. Nynke will look at her code to pull data for passive flexion.
- Ahmet reminded the groups that we need to decide who the lead would be for the benchmarking paper. Deep comparisons of model predictions can be presented as part of this manuscript, e.g., load sharing in ligaments (per Jason), contact load sharing (per Ahmet). These may follow a first pass evaluation of joint mechanics, e.g. may be consider benchmarking as a two part paper.
- Ahmet asked Carl if there was model recalibration in their workflow. He also wondered HSS outcomes for model benchmarking ad reuse. Carl will follow up with Shady. Jason is done with Model Reuse specifications, he will send them. He still needs to work on model reuse outcomes.
- Carl introduced Jacob and mentioned an article on primer for knee anatomy, which he has been working on to improve reproducibility. Jason mentioned about a relevant study that he has been conducting with medical students on the variability in ligament site identification. Denver group also has some relevant data. Participants agreed to have a separate meeting for imaging of ligaments and methods for identification of ligament insertions. Ahmet indicated that we need a knee modeling resources grant for combining data, primers, and representation of the data in a unified way.
- DU, WSU, HSS will be in ORS. The group will promote our work with NIAMS and connect with potential Delphi participants for anticipated renewal.
