E. Adverse Events
There are no adverse events to report.

F. Significance

Successful completion of this study will provide
quantification of the pivot shift test. The data from
this study will be useful for diagnosis, surgical

planning and assessing outcome of treatments for
ACL injuries. The measurement of tibial translation

and acceleration during the pivot shift test coupled
with the standardized pivot shift test maneuver could

provide consistent evaluation of rotatory knee laxity in
ACL deficient and reconstructed knees. These new

non-invasive technologies could be used for patient-
individualized and functional treatment of ACL injury.
