Notes:

  1. Ahmet asked about each team's status on delivering the outputs of Model Development stage. Denver group is on track for within April delivery. Cleveland State University is on track for delivery at the end of April. Hospital for Special Surgery can meet end of April deadline as well. Auckland group is running behind; they have quite a few model changes to make. By the end of April they can get one model done; end of May for both models is more realistic for them. Cleveland Clinic team is on track to meet end of April deadline. Ahmet recommended that groups that can meet the April delivery schedule should submit their Model Development packages when ready and move on to preparation of Model Calibration specifications. Ahmet will make Model Development outcomes of all teams public only after he receives them all. This will give some elbow room for groups that may be falling behind to catch up. It will also allow other groups to move on with the activities of the next stage. Carl wondered if it is feasible that some groups has less to do in calibration phase as they may have done some related activities in the development phase. Ahmet emphasized that the teams should focus on what they proposed to do as part of their Model Development specifications and not necessarily add new activities that can be implemented in next stages. All contributing teams agreed with the discussed scheduling and dissemination plan to finalize the Model Development phase.
  2. Ahmet asked if the teams need any clarification about the preparation of Model Calibration specifications. He had some correspondence with Don about references at the wiki page. He reminded the teams that they can rely on the references and any other information provided in that page. Ahmet and Kevin have had a communication about the Natural Knee Data. Don and Kevin discussed checking the data and noticed that load and displacement data may need to be resynchronized. Kevin offered providing a resynchronized data. Ahmet recommended keeping the data as is; list this issue as a data limitation at the wiki page and let everyone deal with it in their own way. In response to a question from Jason, Don noted that plots of load vs displacement indicate obvious trends related to this issue. Don had a follow up thought related to the longevity of the project by adding a set of corrected calibration set. Will responded that all teams should disseminate reprocessed data and accompanying documentation on how you get the original data set to reproduce this. Ahmet reminded that this was asked in the Model Calibration wiki. He also mentioned the importance of this documentation and dissemination of processed data as these activities will enhance working with readily disseminated Natural Knee Data and Open Knee(s).
  3. Ahmet told that JBME paper on the overview of the project is in press; he has been waiting for proofs. Jason did not have any update on the manuscript to understand reproducibility potential of previous knee modeling studies. Carl indicated that he has provided JOR May as the timeline for tentative submission of workshop summary manuscript. He noted that on the front end there was a lot of work; the manuscript will be more compilation than writing of new material. He will send out drafts by the end of April or early May. He also compiled workshop feedback. Thor wondered if the survey results will be uploaded to the wiki for public release. Ahmet and Carl communicated about making workshop material publicly available either as a separate project site at SimTK or within the our project site. Carl summarized the survey results. There were 103 surveys with ten of them discarded. Most were complete. For 95% of the participants reproducibility was an important issue, 95% like the workshop and 90% indicated that they will come again. Overall, it was great feedback to make the project and knee modeling more visible to the ORS. Carl reached out to organizers to ORS and they will connect us with topic chairs where we can advocate our work in this multidisciplinary conference.
  4. Ahmet mentioned that abstracts from the group (his, Jason's, and Carl's) have been accepted for CMBBE conference as invited talks. The session was supposed to be on the art and reproducibility of modeling. Yet, the abstracts were accepted for a session on modeling and simulation of diarthrodial joints. Ahmet has been in contact with CMBBE to resolve this. Thos will be at ISB. He will give a keynote and will mention the project. Pete will be at ISB as well. Jason asked about ISTA. Pete and Kevin indicated that there will be presentations from their group but not necessarily from them. May 1 is the deadline for ISTA. The group also discussed about the possibility to have a submission on the summary of model development of all groups. This may be too soon; Ahmet wants to wait for eveyone's packages. Ahmet and Carl also caught up in the recent BMES/FDA meeting on modeling and simulation of medical devices.
  5. Ahmet and Kevin had a discussion a while back on Brian's presentation. Brian put together some slides to summarize the Model Development specifications of all the teams to compare and contrast. Ahmet thought that this may be an interesting presentation for all to see. He notified the teams that he is interested in starting webinars that can be presented by team members, for all the groups to get informed and for the presenter to get some practice and exposure. He asked for nominations. Carl wondered if these presentations should be leveraged for community outreach. That will be possibility. If the topic is of broad interest, we can invite external groups. Ahmet intents to record and disseminate the presentations as well.
  6. The group discussed May or June gathering in Denver. Thor will be at ISB in Calgary by the end of July. He will be in Europe the month before. Early June meeting for him is good. Kevin and Pete will be happy to host, creating exciting team building activities. The week of June 10th or June 17th sounds good. Tentative dates were set at June 13-14, 2019.
  7. All previous action items were taken care of.
  8. Shady asked for clarification. In their development stage they proposed to do some calibration. Ahmet noted that if it is in their specifications, they may want to work on it. If they decide to not do it (changed their mind), it can be noted as a protocol deviation with a justification.
