Progress Report

Project Specific Aims

  • To provide an open, freely available, and collaborative development, testing, simulation and dissemination platform for in silico exploration of the biomechanics of healthy and diseased knees.
  • To develop in silico biomechanical models of healthy and diseased knee joints of different genders and ages, supported by specimen-specific joint and tissue level experimental mechanics.

Activities of Progress Period

  • Cloud computing prototype

    • Cleveland Clinic and Stanford University teams continued to have monthly conference calls to to discuss web based computation interface. Please refer to meeting minutes in Cleveland Clinic - Stanford University section of ["RecurringMeetings"].

    • Detailed specifications on a prototype for web-based computing infrastructure was provided by the Cleveland Clinic team, see [http://wiki.simtk.org/openknee/Specifications/CloudComputingPrototype?action=recall&rev=19 Revision as of May 18, 2013] or [:Specifications/CloudComputingPrototype: current version].

    • A prototype of a web-based interface for submission of simulations was developed on a staging server; this was summarized in the progress report submitted to National Institutes of Health along with a snapshot of the interface, see https://simtk.org/websvn/wsvn/openknee/doc/R01_rppr-y1-activities.pdf.

    • Upcoming steps include development of a results retrieval interface, model administration interface, and launching of cloud computing infrastructure.
  • Simulation software features

    • Cleveland Clinic and University of Utah teams continued to have monthly conference calls to to discuss enhancements in FEBio, the simulation software used in Open Knee(s). Please refer to meeting minutes in Cleveland Clinic - University of Utah section of ["RecurringMeetings"].

    • The Cleveland Clinic team detailed the prioritization of desired features and provided various test problems, see [http://wiki.simtk.org/openknee/Specifications/FebioFeatures?action=recall&rev=38 Revision as of May 18, 2013] or [:Specifications/FebioFeatures: current version].

    • Feature to accommodate in situ ligament strains was implemented; this was summarized in the relevant wiki page, see [http://wiki.simtk.org/openknee/Febio/InSituStrain?action=recall&rev=14 Revision as of May 18, 2013] or [:Febio/InSituStrain: current version]. This activity was also summarized in the progress report submitted to National Institutes of Health along with some preliminary results, see https://simtk.org/websvn/wsvn/openknee/doc/R01_rppr-y1-activities.pdf. Relevant to this work, a conference abstract was submitted to CMBBE 2014, 12th International Symposium on Computer Methods in Biomechanics and Biomedical Engineering. Additional work will be conducted for general purpose use of this feature. It is anticipated that FEBio version 2.0 will incorporate this implementation.

    • Upcoming activities for simulation software enhancements include work on set definitions and rigid body movements.
  • Experimentation
    • Experimentation on Specimen 001 had to be postponed to accommodate maintenance and upgrades to the robotics testing system. The anticipated timeline for data collection, dissemination, and related modeling efforts was pushed back by approximately three months.
    • Three knee specimens were acquired and identified as the first set of Open Knee(s) - Generation 2 specimens:

    • The experimentation workflow was illustrated in the specifications wiki page; see experimentation workflow section in [http://wiki.simtk.org/openknee/Specifications?action=recall&rev=36 Revision as of May 18, 2013] or [:Specifications: current version].

    • A large group of experimentation specifications, detailed description of protocols, are in a mature state (completely documented or close finalization):
    • The team has also worked on other experimentation steps to finalize the protocols and enable their achievement:

      • Specimen preparation was found to be a logistically challenging task given the intensity of experimentation that need to be conducted on a specimen. Various stages were agreed upon by the team and documented in the relevant wiki page, see [http://wiki.simtk.org/openknee/Specifications/SpecimenPreparation?action=recall&rev=90 Revision as of May 18, 2013] or [:Specifications/SpecimenPreparation: current version]. Remaining work on this specification (about joint level preparation) is merely editorial. Additional documentation is needed about tissue level preparation.

      • The Cleveland Clinic team purchased a materials testing machine dedicated for Open Knee(s) tissue testing needs, see section on characterization of tissue mechanical properties in ["Infrastructure/ExperimentationMechanics"]. Tissue testing on this setup has been performed; as pilot tests and as part of preliminary work on tissue material properties conducted with Elvis Danso & Rami Korhonen, which is relevant to Open Knee(s). Detailed tissue testing specifications needs attention, see [http://wiki.simtk.org/openknee/Specifications/ExperimentationTissueMechanics?action=recall&rev=11 Revision as of May 18, 2013] or [:Specifications/ExperimentationTissueMechanics: current version].
