The primary purpose of this study is to determine the interrater reliability and validity of
the Sportcord Test as a measure of physical performance following anterior cruciate ligament
(ACL) reconstruction. A secondary purpose is to systematically track subjective and
objective outcomes on patients following ACL reconstruction to help identify differences
between those who have subsequent knee problems and those who do not. The study hypotheses
are the following:
1) The Sportcord Test will provide a valid and reliable measure of functional performance
following ACL reconstruction. 2) Patients who have subsequent knee problems in the 12 month
study period will exhibit different scores on clinical special tests compared to those who
- Undergoing surgical reconstruction for a torn ACL.
- Returning to participation in a sport(s).
- Will receive physical therapy/rehabilitation after surgical reconstruction for a torn
- Between ages of 10 and 50.
- Non-weight bearing.
- At least 12 weeks removed from surgery.
- Unable to walk, squat, or jump/land without pain in the surgically repaired knee.
