Additional Information:
Brief summary description of your project, include what worked and what did not work.
Our project was successful in that we were able to complete the necessary aims described in our
proposal, testing 8 cadaveric knees across both translational and rotational biomechanics and
assess the ability of our surgical technique to restore stability to the knee via the ACL. This led to
a poster presentation at the Maryland Orthopaedic Association meeting and a manuscript that has
been written (attached to the email). We would have preferred a better “potting” technique for the
knees though the MTS machine that we were using for testing our specimens also limited this. In
addition, if we had access to more knee specimens, we would have been able to trial more
specimens to increase our ‘n’ for the study.
 
Was the primary outcome measure of success reached?
Yes, the primary outcome measure was achieved in that we were able to demonstrate that retensioning
the residual posterolateral bundle after an AM bundle tear of the ACL restores anterior
translation without affecting rotational stability. The POSNA micro-grant was pivotal in the
success of this project and allowed us to have the financial means to achieve the ultimate goal of
our project-thank you!
 
Future plans, presentations or publications as a result of this grant.
We hope to present this in a podium format at POSNA as well as other conferences. Our biggest
goal is to have our manuscript accepted for publication-it is currently in submission to
Arthroscopy.
