Recurring Meeting of Cleveland Clinic Core Team

Date: September 15, 2015

Time: 10:30 AM EST

Means: In person meeting

Attendees:

1. Ahmet Erdemir
2. Craig Bennetts
3. Snehal Chokhandre
4. Robb Colbrunn
5. Tara Bonner
6. Joseph Lesueur

Agenda:

1. Discuss immediate action items from the last meeting.
2. Discuss progress of tissue testing protocol evaluation.
3. Decide immediate action items for the next meeting.
4. Other.

Immediate Action Items:

• Ahmet
  • Disseminate the remainder of joint mechanics testing data.
  • Prepare flowcharts to describe data flow for pre-processing of joint kinematics/kinetics data.

• Robb & Tara

  • Go through in-house data management system to ensure completeness of joint mechanics data for specimens that has not been disseminated.
• Craig
  • Start documenting meshing experience using various software in relevant mesh generation wiki page.
  • Explore hexahedral meshing workflows in Salome for STL surfaces.
  • Document in the relevant wiki page convergence of Open Knee(s) - Generation 1 model when using springs.
• Snehal
  • Follow-up Scientific Data to assess suitability of Open Knee data for publication.
  • Follow-up with Anatomy Gifts Registry, another specimen supplier, for new specimens.
  • Design optical thickness measurement system frame (check 80/20).

Ongoing Action Items:

• Craig
  • Anatomical imaging manuscript.
  • Large-scale analysis of simulation parameters for convergence.
• Snehal
  • Pivot shift manuscript.

  • Cruciate ligament modeling & simulation.

• Robb
  • Patellofemoral joint experimentation manuscript.
• Tara
  • Tibiofemoral joint experimentation manuscript.

Notes:

1. Discuss immediate action items from the last meeting.
   • Ahmet disseminated joint mechanics data for oks006. He noted that some data appears to be missing. So far, he has identified that contact pressure calibration files for oks002 were not uploaded to in-house data management system. He also noted that data for left knees, e.g. oks003 were only available in right knee abstraction. Ahmet asked Robb and Tara to go over the joint mechanics data in the in-house data management system and upload additional files for completeness. Ahmet also mentioned that there are groups interested in using the data. Trent Guess submitted an NSF grant application proposing to utilize patellofemoral joint testing data. Jason Halloran is also planning to use Open Knee(s) data. Jason and his student (Will Zaylor) will be attending Open Knee(s) meetings in future.
   • Ahmet contacted Carl Winalski to arrange time for grading of the knees from MRI.
   • Craig successfully meshed the tibial cartilage in Salome using hexahedral elements. He will document his meshing experience in mesh generation specifications; e.g. hex meshing in IA-FEMesh using STL surfaces, hex meshing in Salome using IGES. He will also explore hex meshing in Salome starting with STL surfaces. The group discussed potential issues relevant to defining element, node, surface sets on the meshes. This process will likely be manual, e.g. picking nodes, faces, elements in Salome using the mouse. Nonetheless, manual selection in Salome is easy to use.
   • Snehal has been awaiting for a response from the editor of Scientific Data on the suitability of Open Knee(s) data for publication. She has not received any information from other specimen suppliers yet.

Order specimens from Anatomy Gifts Registry, another specimen supplier.
