Brief Summary
The purpose of this study is to see if the study team can use micro-Doppler signal (MDS) technology to determine if someone has had an anterior cruciate ligament (ACL) reconstruction. The investigators will do this by comparing the movement data from a group of people who have had the surgery with a group who has not had the surgery to see if the micro-Doppler radar technology can accurately and predictably tell the difference.

Outcome Measures
Primary Outcomes (1)
accuracy and predictability of MDS differentiation between ACL repair and control group
The investigators hypothesize that MDS will differentiate subjects who have recovered from an ACL reconstruction from a control cohort with accuracy and predictability. Participants will perform drop jumps, sit to stand, and walk on a treadmill in the presence of the micro-Doppler radar. MDS will be obtained for the ACL group as well as control. The micro-Doppler signature projection algorithm (mD-SPA) will then be applied to the data sets showing what percentage of the MDS are successfully classified to the ACL group versus control.
Day 1
Secondary Outcomes (2)
accuracy of MDS differentiation between ACL repair and control groups versus the motion capture system
Day 1
ability of micro-Doppler radar and deep learning algorithms to automatically produce predictive data
Day 1
Study Arms (2)
high risk/ACL repair cohort
The high risk cohort will be subjects who have had an ACL reconstruction procedure 9-24 months prior to enrollment.
control group
The control group will be individuals who have not had an ACL reconstruction procedure.
