Date: October 21, 2014

Time: 10:30 AM EST

Means: In person meeting

Attendees:

1. Ahmet Erdemir
2. Snehal Chokhandre
3. Robb Colbrunn
4. Tara Bonner

Agenda:

1. Discuss immediate action items from the last meeting.
2. Discuss coordinate systems and transformation matrix information required to build and run FE models.
3. Discuss oks002 testing plan.
4. Decide immediate action items for the next meeting.
5. Other.

Immediate Action Items:

• Ahmet
  • Setup a test problem to evaluate workflow of joint data processing for modeling purposes.
• Snehal
  • For oks001, provide information on specimen preparation including notes, deviations, and team members.
• Tara

  • Provide documentation on SimVitro configuration files to extract registration and kinematics information (potentially requires few weeks).

• Robb & Tara

  • Review tissue testing specifications.

• Snehal & Craig

  • For oks001, provide information on joint imaging including notes, deviations, and team members.

• Robb & Tara

  • For oks001, provide information on tibiofemoral joint testing including notes, deviations, and team members.

• Robb & Ahmet

  • For oks001, provide information on patellofemoral joint testing including notes, deviations, and team members.

Notes:

1. Discuss immediate action items from the last meeting.
   • Snehal updated tissue testing specifications. In particular, she described how the loads are applied in a way to collect data at different frequencies during hold periods of stress-relaxation. She also organized specifications for each type of tissue. Robb and Tara will read and review these specifications for next week.
   • Snehal was not able to finish meniscus testing for oks004 as she was waiting for the O-rings to prevent leakage of the tissue bath. O-rings are received and the tissue testing can continue.
   • For oks004 tissue components, Snehal changed the sample labeling to conform data management strategies.
   • Tara provided laxity curves for oks001. The data seem to be in order and the laxity response appears to be as expected.
   • For summarizing coordinate systems, Snehal and Craig will need another meeting with the group (also see the following agenda item).
   • Updates for oks001 specimen page were discussed.
     • Snehal filled out various sections of the oks001 wiki page. There are not many issue and deviations for joint level imaging and testing.
     • All group members were asked to fill in information on the parts they were in charge of (including notes, deviations, team members): Robb and Tara - tibiofemoral joint testing (include laxity curves), Robb and Ahmet - patellofemoral joint testing, Snehal - specimen preparation and dissection, Snehal and Craig - imaging
   • The group emphasized the need to consolidate joint and tissue testing tools (grips, supplies) potentially by listing them in a database. There are issues with various tools, fixtures, parts missing. Also some parts may return as damaged, i.e., some of the screws stripped tapped holes of the tension grips. To prevent this, all were advised to use torque wrench when using tension grips. Various ways to keep track of supplies were discussed, e.g., labeling, logging, sign-out sheet. Robb and Tara will provide a sign-out sheet to exchange of tools between laboratories.
